What should you do if you are pregnant during Singapore haze? Begin with the NEA one-hour PM2.5 reading and the Ministry of Health’s pregnancy-relevant haze advice. Pregnant women are included in the group advised to take greater care with outdoor exposure. When pollution is elevated, reduce or avoid outdoor activities according to the current band, especially prolonged or strenuous exercise. Keep essential prenatal appointments organised rather than cancelling medical care by yourself. Reduce smoky air entering the home when appropriate, maintain a comfortable and safely ventilated room, and discuss respiratory symptoms or personal complications with your own obstetric team. A well-fitted N95 can reduce particle exposure in selected necessary outdoor situations, but masks increase breathing resistance and are not universally suitable during pregnancy.
This Singapore haze pregnancy guide covers first-, second- and third-trimester daily life, prenatal appointments, walking, swimming, gym classes, commuting, HDB windows, air conditioners, HEPA purifiers, N95 masks, fatigue, sleep and family support. It is written for expectant parents who want practical guidance without frightening unsupported claims about a baby’s risk from a single PSI reading. The HealthHub pregnancy exercise guide supports appropriately adapted physical activity during pregnancy; MOH’s haze advisory adds a separate environmental-exposure decision. Combining the two helps a family preserve healthy routines while avoiding unnecessary smoky-air exposure.
In Singapore’s October 2026 haze episode, the NEA Haze Task Force notice of 9 October specifically named pregnant women among groups requiring more precautions. It also described workplace adjustments, community responses and conditional mask distribution when PSI becomes Very Unhealthy. That statement is relevant context from a dated event, not a permanent forecast. Each day, refer to current official measurements and your own clinical care plan.
The immediate pregnancy haze checklist
Start with the real decision you face: a short journey to a clinic, an optional morning walk, a prenatal yoga class, an outdoor family celebration or a day at work. Do not treat them as identical exposures. A necessary medical appointment has a different priority from a prolonged recreational jog, and an enclosed classroom is not the same environment as an open-sided fitness studio.
Check the one-hour PM2.5 reading for an outdoor activity about to start. Then read the MOH guide for vulnerable people, a category that includes pregnant women. If the activity involves several hours outdoors or physical exertion, consider whether a shorter route, suitable indoor alternative or postponement is sensible. Do not base the decision solely on how smoky the sky looks.
Next look at your own health. Are you unusually breathless, dizzy, wheezy or experiencing another concerning symptom? Has your clinician placed restrictions on exercise or travel for an existing pregnancy condition? An environmental reading cannot overrule individual medical advice. If you are unwell, obtain appropriate clinical guidance promptly.
Finally make the household plan easy. Know the transport for prenatal visits, keep needed medication and contact details accessible, decide which outdoor errands can be delegated or combined, and prepare a comfortable room. There is no advantage in turning the entire pregnancy into continuous air-quality monitoring.
The difference between PSI and one-hour PM2.5
Singapore’s Pollutant Standards Index, or PSI, is an air-quality index used with the 24-hour forecast for planning. One-hour PM2.5 indicates a more immediate concentration of fine airborne particles, measured in micrograms per cubic metre. These are related but different measures; do not equate their numbers or subtract one from the other.
MOH’s one-hour PM2.5 bands are Normal at 0–55, Elevated at 56–150, High at 151–250 and Very High at 251 or above. For vulnerable people, including pregnant women, the advisory recommends avoiding strenuous outdoor activity at Elevated and avoiding all outdoor activity at High and Very High for the next hour. The exact guidance should be read directly from MOH’s latest table, because personal conditions can warrant further caution.
For the following day, the 24-hour PSI forecast categories are Good 0–50, Moderate 51–100, Unhealthy 101–200, Very Unhealthy 201–300 and Hazardous above 300. When the forecast is Unhealthy, pregnant women are advised to minimise prolonged or strenuous outdoor exertion. At Very Unhealthy, minimise outdoor activity; at Hazardous, avoid outdoor activity.
A forecast is not a pregnancy-specific exposure diagnosis. It also is not a reading inside your own bedroom or doctor’s waiting room. Use it as public-health information to guide practical decisions, alongside clinical advice and symptoms.
Why pregnancy receives more cautious haze advice
Pregnancy brings physiological changes, including changes in breathing, circulation, fatigue and the body’s response to physical exertion. The degree and timing vary from person to person. Singapore’s public-health advice therefore places pregnant women among the vulnerable groups when haze is significant, alongside older people, children and people with chronic lung or heart disease.
It is reasonable to want to protect both yourself and the developing baby. At the same time, a general health guide should not calculate an individual’s fetal risk from a single regional PSI value. Environmental health studies may discuss population-level associations, but those findings cannot be translated into a guaranteed outcome for one pregnancy on one afternoon. Avoid internet claims that “every hour outside causes a particular complication” unless credible evidence supports the exact statement.
The most useful protective measures are practical: follow current official outdoor-activity guidance, avoid unnecessary smoke exposure, manage indoor air appropriately, keep normal antenatal care and respond to symptoms. Do not replace prescribed medical treatment with supplements marketed as haze detoxifiers.
If you have a high-risk pregnancy, asthma, significant anaemia, heart disease or other relevant medical conditions, seek personalised instructions. A generic article cannot identify a safe exertion level or respirator duration for every expectant parent.
First trimester: early pregnancy and everyday work
During the first trimester, some people experience nausea, fatigue and changes in energy. Haze-related planning should not assume that every expectant parent can easily add a longer transport route or an elaborate indoor exercise class. Start by keeping essential appointments and managing discomfort with the guidance of your healthcare provider.
If a walk to the MRT normally takes several minutes, assess whether the actual route and current air quality warrant an adjustment. A short necessary journey may still be workable, while an optional long outdoor workout can be changed. If you feel unwell, the personal medical issue deserves attention, regardless of whether PM2.5 is categorised as Moderate or Elevated.
Physical activity can remain beneficial during uncomplicated pregnancies, but a person who was not previously active should not begin a vigorous new programme solely because outdoor haze disrupts normal life. HealthHub’s pregnancy exercise advice recommends gradual, comfortable and appropriate activity, with clinical advice where needed.
Be careful about indoor remedies for nausea. Strong fragrances, incense or aerosol sprays may add irritating substances to a room, especially when windows are temporarily closed against smoky outdoor air. A pleasant scent is not a PM2.5 filter.
Second trimester: movement without unnecessary outdoor exposure
The second trimester can bring greater energy for some expectant parents, making walking, gentle fitness or a prenatal class attractive. But the time of pregnancy does not change the fact that outdoor air can be smoky. The MOH haze advisory remains relevant to pregnancy, and individual medical recommendations should still guide activity.
HealthHub suggests that appropriate pregnancy exercise can include walking, stationary cycling, suitable strength movements, swimming and some prenatal yoga. The exact choices depend on the individual. During poor outdoor air, a confirmed suitable indoor class may be more practical than an extended park walk, provided the room’s actual air quality and the person’s medical situation support it.
Avoid describing every sheltered studio as an indoor low-pollution space. An open-sided hall can admit smoky outside air even if it has a roof. Ask the provider about the real environment and current programme status. A closed air-conditioned room may reduce outside particle entry but still requires adequate ventilation and safe operation.
A family can adjust without losing all physical activity. If the outdoor walk is postponed, consider an appropriate indoor alternative or rest. A healthy pregnancy fitness plan is measured over time, not by whether a particular evening session was completed regardless of conditions.
Third trimester: comfort, breathing and travel are central
Later pregnancy may involve increasing fatigue, altered balance, more frequent bathroom needs and breathlessness with exertion. For some, travelling across Singapore for an optional class can become more demanding even before haze is considered. The goal is to preserve comfort and safety while following both antenatal and air-quality guidance.
MOH specifically cautions that women in the second and third trimesters may already have reduced lung volumes or breathing issues and should not use an N95 or equivalent respirator for long durations. It also says pregnant women who have difficulty breathing at rest or with exertion should consult their doctor before using one. This is much more useful than a blanket internet instruction to wear a respirator continuously throughout every journey.
Plan transport to prenatal appointments early. Know the building entrance, clinic contact, waiting arrangements and suitable transport route. A predictable and accessible journey can reduce stress and unnecessary exposure. If a visit needs adjustment, discuss it with the clinical team rather than automatically cancelling it.
Do not dismiss new significant breathlessness as ordinary third-trimester discomfort or automatically blame haze. If you develop serious breathing difficulty, chest symptoms, fainting, bleeding, reduced fetal movements or another obstetric warning sign, seek urgent medical evaluation according to the situation. Individual care takes priority over a scheduled outdoor event.
N95 masks during pregnancy: exactly what MOH says
Respirators can filter fine particles when they meet appropriate standards, are fitted correctly and are used in suitable circumstances. MOH states that N95 or equivalent masks are generally not needed for short ordinary trips from home to school or work, nor for indoor environments. The first precaution is to reduce outdoor activity and exertion when the guide calls for it.
When one-hour PM2.5 is High, vulnerable people who must be outdoors for necessary immediate activities may wear a well-fitted N95 or equivalent to reduce exposure. But the fit, health status and duration matter. Pregnant women who have breathing difficulty should consult a doctor before use. During the second and third trimesters, prolonged N95 use is specifically discouraged by MOH.
A respirator increases the effort required to breathe. If it causes discomfort, follow the official advice to take a break; do not ignore worsening symptoms merely to complete a commute or fitness session. Masks should not be shared. Different certified standards, such as KN95, KF94 and FFP2, have their own requirements. Avoid assuming a loose surgical mask provides identical fine-particle filtration.
Do not make an N95 the centre of the entire pregnancy plan. A shorter necessary trip, appropriate indoor air and clinician-guided care may be more important than buying a fashionable or uncomfortable mask.
Prenatal appointments: keep the medical schedule in view
Routine prenatal care, ultrasounds, specialist reviews and medical tests are not equivalent to recreational outings. If air quality worsens, contact your clinic about any concern and follow its advice. Do not skip a medically important appointment based on a social-media haze forecast or a general blog article.
A practical appointment plan covers departure time, transport, waiting, a safe pickup point and return journey. Someone attending a clinic near an MRT station may still need to cross an exposed plaza or wait outside for a ride. Shortening unnecessary outdoor time may be useful when current guidance advises less exposure, especially if the expectant parent is tired or breathless.
Keep pregnancy records and relevant medication information available through the usual care system. Do not self-adjust prescribed medicines because of pollution. If an appointment is rescheduled, note the new date and any instructions about tests or symptoms that should be reported in the meantime.
Caregivers and partners can help by arranging transport, collecting groceries or looking after older children, where appropriate. Support does not have to be elaborate to reduce avoidable strain.
Walking in pregnancy: don’t treat a park as obligatory exercise
Walking is often recommended as a convenient form of pregnancy activity, and HealthHub describes its benefits and practical precautions, including hydration and avoiding overheating. In Singapore, parks and connectors make walking easy. During haze, however, prolonged outdoor walking may need to be reduced or postponed.
A person who normally walks thirty minutes at East Coast Park, MacRitchie, Jurong Lake Gardens or Punggol Waterway should check current air-quality advice before leaving. A waterside breeze or wooded path does not guarantee low PM2.5. A covered park walkway is not necessarily enclosed or filtered.
If the official guide advises avoiding strenuous or all outdoor activity for vulnerable people, an outdoor fitness target should not override it. An appropriate indoor walk, gentle clinician-approved movement or rest may fit the day’s needs better. Do not invent a precise safe number of steps for all pregnant people.
Exercise during pregnancy should be comfortable, and unusual pain, dizziness, breathing difficulty or other concerning symptoms should prompt stopping and seeking clinical advice. The aim is health, not competitive performance.
Swimming, yoga and indoor exercise
Swimming can be a useful low-impact option for an uncomplicated pregnancy, but an outdoor pool is still exposed to outside air. The water’s cleanliness does not tell you the PM2.5 concentration the swimmer inhales. A sheltered teaching pool may have open sides, and an indoor pool’s ventilation or chemical environment can vary.
Before a swim, check the operator’s current status and the actual venue. SportSG’s haze management measures explain how facilities and programmes may change during haze. The Singapore Haze Swimming Guide gives the detailed pool decision, including partial shelter and programme closures.
Prenatal yoga or appropriate strength training may be possible in a suitable indoor environment, but “indoor” is not a guarantee of perfect filtration. Check whether the class uses an enclosed room and whether the instructor is qualified to adapt movement for pregnancy. Tell the instructor about relevant clinical restrictions. Avoid heat and overexertion and never treat internet exercises as a substitute for medical advice.
HealthHub’s Being Fit When Pregnant discusses gradual movement and warning signs. If physical activity triggers concerning symptoms, stop and seek appropriate guidance. The purpose is sustainable wellbeing, not replacing every missed outdoor workout with another hard session.
Work and commuting during haze
Many pregnant people continue work throughout much of their pregnancy. Some commute by MRT and bus; others work outdoors or must move between locations. Their options differ. A desk-based employee may be able to rearrange meetings or work from home in some circumstances. An outdoor worker or a person with fixed site duties needs a more structured exposure assessment.
The Ministry of Manpower’s haze guidelines require attention to susceptible workers and appropriate safeguards for outdoor duties. Pregnant workers may need arrangements that limit prolonged strenuous exposure. Discuss relevant needs through suitable workplace and medical channels rather than relying on informal group advice.
For an ordinary commute, plan the actual door-to-door route: home to stop, waiting, main ride, transfer and final entry. A roofed bus stop may be open to outdoor air; an enclosed train carriage is different but not guaranteed to have a specific particle concentration. Choose a comfortable safe journey and avoid unnecessary outdoor detours.
An appropriate arrangement should not require dangerous rushing. Pregnancy can change balance and energy, and the last thing a haze plan should do is increase fall or traffic risk to save a few minutes outdoors.
HDB windows and balcony doors: a realistic home-air routine
During a period of poor outdoor air, temporarily closing windows and doors where appropriate can reduce haze particles entering the home. The actual effect depends on room leakage, ventilation and indoor sources. An HDB flat is not a sealed laboratory; open corridors, service yards and other pathways may let outside air enter.
Use the room where the expectant parent spends significant time as a practical priority. Keep it comfortable, avoid smoking and burning incense, and consider suitable particle filtration if available. A fan moves air but does not by itself filter PM2.5; air conditioning cools a room but its filtration performance varies.
The home also needs adequate ventilation and reasonable temperature. Do not permanently block essential vents, disable appliance safety arrangements or overheat the room by insisting every opening remain closed indefinitely. Reassess when outside air improves, using HealthHub haze precautions and any relevant building guidance.
The Singapore Haze at Home Guide explains room sizing and filter selection. Pregnant readers do not need to memorise every filtration specification to make a sensible daily plan.
HEPA and CADR: air purifiers without miracle promises
A portable air cleaner with suitable particulate filtration can lower indoor fine-particle concentrations when it is correctly sized, installed and maintained. A HEPA filter is one effective particle-filter technology, but the actual appliance’s airflow and leakage also matter. A scented device or a fan without effective filtration is not equivalent.
NEA’s air-cleaning devices guidance discusses particle removal. Clean Air Delivery Rate, or CADR, is useful for comparing how much cleaned air an appliance delivers under a particular test. Check the room volume and smoke CADR, not just an attractive “large room” label.
A purifier cannot guarantee zero haze particles, remove every gas or provide an adequate fresh-air supply by itself. Effectiveness depends on closed or open windows, filter condition, room size and indoor sources. A device placed behind a curtain or used only briefly may deliver less benefit than its advertisement implies.
There is no medical reason to demand that every expectant parent buy a costly purifier immediately. Source control, appropriate management of smoky-air entry, safe ventilation and prescribed medical care remain important. Avoid product claims that a device will prevent specific pregnancy complications without evidence.
Sleep during haze and the temptation to worry all night
Sleep matters for comfort and wellbeing during pregnancy. Haze can add respiratory irritation or anxiety, but it should not be assumed to cause every episode of poor sleep. Pregnancy itself, work patterns, temperature, stress, late caffeine and unrelated medical conditions can influence rest.
Create a comfortable sleeping space, manage outdoor-air entry sensibly and keep a familiar bedtime routine. Avoid burning incense or using strong fragrances as a supposed air purifier. A cool room may help comfort, but cooling is not proof that fine particles have been removed.
If coughing or breathlessness repeatedly disrupts sleep, speak to a healthcare professional. Do not independently take over-the-counter medicines, supplements or sedatives simply because they promise relief from haze. Pregnancy can change medication suitability; ask a qualified clinician or pharmacist who knows the pregnancy.
The Singapore Haze and Sleep Guide has more detail on bedroom air, nocturnal symptoms, HEPA and sleep habits. The practical goal here is to support a pregnant person’s rest without creating a cycle of anxious checking.
Morning sickness, food and the false “haze detox” idea
Singapore food culture offers many comforting meals and drinks, and relatives may suggest herbal tea, soups or supplements when haze appears. Good nutrition and hydration support everyday health, but there is no sound basis for claiming that a particular meal removes inhaled PM2.5 from the lungs or guarantees protection for the developing baby.
During pregnancy, diet and supplement choices may have medical considerations independent of haze. Do not take unregulated products, concentrated herbal preparations or large additional doses of supplements because a social-media post advertises them as air-pollution detox. Discuss relevant questions with a maternity-care professional.
Cooking at home is a reasonable way to avoid some outdoor trips, but high-temperature frying and smoky indoor cooking can add particles. Use appropriate safe kitchen ventilation, avoid indoor smoke sources and keep the room comfortable. Do not obstruct required ventilation for fuel-burning equipment in an attempt to exclude outside haze.
A family can have a good meal at home, order takeaway or use a suitable enclosed dining venue when the trip and health advice permit it. Our Singapore Haze and Hawker Centres guide explains the distinction between open-air dining exposure and ordinary food hygiene.
Pregnancy symptoms: what haze does not explain
Mild throat or eye irritation can occur during haze, but symptoms in pregnancy deserve broader consideration. Significant breathlessness, chest pain, fainting, vaginal bleeding, severe abdominal pain, fluid leakage, concerning swelling or reduced fetal movements can indicate important conditions unrelated to smoke and should not be dismissed as normal haze discomfort.
HealthHub’s guidance on being fit when pregnant lists exercise warning signs that should prompt stopping activity and seeking medical advice, including chest pain, dizziness, vaginal bleeding, fluid leakage and decreased fetal movements. The exact appropriate response depends on symptom severity and pregnancy stage. Seek urgent medical help for serious symptoms.
A pregnancy health plan should name the hospital or clinic contact, usual instructions and emergency route. Do not rely on an app showing Moderate pollution to reassure yourself when a serious clinical problem is occurring. Air-quality data describes the environment; it cannot diagnose a pregnancy.
Equally, do not automatically blame haze for every headache or cough. Infections, dehydration, pregnancy complications and other causes require proper assessment when relevant. This distinction avoids both unnecessary alarm and dangerous false reassurance.
Outdoor weddings, festivals and family gatherings
Pregnant guests may be invited to a wedding, outdoor concert, garden celebration or community event while haze is present. A ticket or invitation does not override individual public-health advice. Consider the current PM2.5 band, time outdoors, seating, access to a comfortable enclosed room and the option to leave without a long queue.
An outdoor wedding can involve more exposure than the ceremony itself: waiting for photographs, dining under an open-sided tent, travelling between sites and remaining for an evening reception. Ask the host or organiser whether a suitable indoor option or shorter attendance is possible. You can celebrate an important occasion without preserving every outdoor minute.
Avoid feeling obligated to explain private pregnancy complications to everyone. A simple statement—“I need an indoor or shorter arrangement for health reasons”—may be enough. If the event is not suitable, missing an optional part can be a reasonable decision.
Our Singapore Haze and Outdoor Events Guide provides practical contingency ideas for organisers and guests.
A partner or family’s practical support plan
Support can be concrete rather than dramatic. If outdoor air is poor, someone else may be able to collect groceries, coordinate school pickups, confirm a prenatal appointment or arrange transport. Those changes can reduce unnecessary exertion and outdoor waiting without requiring the pregnant person to stop participating in ordinary family decisions.
Make a short checklist: current official readings, essential healthcare schedule, transport, comfortable home room, medications if prescribed, contact details and a plan for unexpected symptoms. Ask the expectant parent which tasks actually feel burdensome. Different households have different work schedules and budgets, so the plan must fit reality.
Family members should avoid pressuring someone to take unverified supplements, wear a respirator continuously indoors or cancel medical care without professional advice. Helpful support means reducing unnecessary friction and respecting clinical recommendations.
A good household also avoids constant alarming messages. When someone has already checked the official readings and made an appropriate plan, repeated speculation about air-quality trends may add stress without improving safety.
Four realistic Singapore scenarios
Clementi: first trimester and work travel. A pregnant office worker has a necessary morning commute and a planned evening park walk. She checks one-hour PM2.5 and MOH guidance, keeps the work journey practical and adjusts the optional long walk if the band warrants it. She does not assume an N95 is required for every short transit segment.
Punggol: second trimester and prenatal yoga. A parent-to-be wants to attend an outdoor wellness class beside the waterway. Haze conditions make that setting less suitable. The class can be rescheduled or moved to a verified suitable indoor environment with an instructor trained to modify movements for pregnancy. If she is unwell or has clinical restrictions, she follows her care team’s advice.
Bedok: third trimester and specialist appointment. An expectant parent has an appointment requiring travel. The family checks transport and the clinic’s instructions, avoids unnecessary waiting outside and keeps the appointment unless told otherwise. They do not insist on prolonged respirator use despite breathing discomfort; MOH’s third-trimester cautions are considered.
Queenstown: staying home with an older child. A pregnant mother is caring for a preschooler while outside air is poor. The family adjusts HDB windows appropriately, uses a comfortable room, avoids indoor smoke sources and chooses a short story or craft activity instead of an extended outdoor playground session. The parent remains attentive to her own symptoms and the child’s needs.
These examples are not claims about a fixed pollution level in any named neighbourhood. The same reasoning can be used across Singapore with the current official readings.

Frequently asked questions about pregnancy and Singapore haze
Are pregnant women considered vulnerable during haze?
Yes. MOH includes pregnant women in the group receiving more cautious outdoor-activity advice. Use the one-hour PM2.5 guide for immediate activity and the 24-hour PSI forecast for planning, alongside your individual medical care.
Is haze exposure guaranteed to harm my unborn baby?
A single regional PSI reading cannot predict a particular baby’s health outcome. Environmental risks should be taken seriously, but unsupported claims about precise individual outcomes are misleading. Follow public-health exposure advice and discuss personal concerns with your obstetric clinician.
Can I walk outdoors in the first trimester during haze?
Consider current PM2.5, duration, exertion and your health. MOH’s vulnerable-person guidance applies throughout pregnancy. When the band advises avoiding strenuous or all outdoor activity, adapt or postpone the walk. Consult your clinician if you are unwell or have pregnancy-related restrictions.
Should I wear an N95 mask whenever I leave home?
No blanket requirement follows from MOH’s advice. Respirators are generally unnecessary for short commutes and indoors. They may help in selected necessary outdoor situations at high particle levels, but breathing resistance and medical suitability matter. Follow the current MOH guidance and your doctor’s advice.
Can I wear N95 for several hours in my third trimester?
MOH specifically says women in the second and third trimesters should not use N95 or equivalent masks for long durations. Pregnant women with breathing difficulty should consult a doctor before use. Adjusting the trip and reducing unnecessary exposure are important alternatives.
Is swimming during haze safe when pregnant?
Swimming can be a suitable low-impact exercise during an uncomplicated pregnancy, but an outdoor pool still has outdoor air. Check the current health guide, pool operations and individual medical advice. An indoor venue is not automatically guaranteed to have perfect filtration.
Should I cancel prenatal scans because of poor PSI?
Do not cancel essential healthcare without consulting the provider. Plan sensible transport and discuss any unusual symptoms or concerns with the maternity team. The medical importance of the appointment and your individual condition determine the next step.
Will an air purifier protect my pregnancy completely?
No appliance can guarantee complete elimination of pollution or prevention of a specific medical outcome. Effective particle filtration may reduce indoor PM2.5, but room size, maintenance, ventilation and incoming air matter. Use it as one environmental measure alongside clinical care.
Is it safe to close HDB windows all day?
Temporarily reducing smoky-air entry may help during poor outside conditions, but adequate ventilation and comfortable temperature still matter. Reassess when the air improves and do not block essential safety ventilation. Follow NEA and HealthHub guidance.
Is prenatal yoga indoors automatically free from haze?
Not necessarily. An open-sided studio may admit outdoor air, and an enclosed studio’s filtration varies. Check the actual setting, programme and instructor. Exercise intensity and individual pregnancy restrictions still require attention.
Should I stop all exercise until haze season ends?
Not necessarily. Suitable activity during pregnancy can remain beneficial, but location and intensity may need adjustment. Follow MOH’s current haze guidance and your clinician’s advice. Rest can be appropriate when symptoms or conditions make activity unsuitable.
Can herbal drinks or supplements detoxify haze particles?
There is no sound basis to claim they filter inhaled PM2.5 or protect a pregnancy from all smoke exposure. Some preparations may not be suitable during pregnancy. Discuss supplements and medication with an appropriate healthcare professional.
What if I am short of breath at night?
Consider the severity and other symptoms. Breathlessness during pregnancy can have several causes, some serious. Significant, new or worsening breathlessness, chest symptoms or fainting requires prompt assessment. Do not assume haze is the only explanation or wait for a lower PSI.
Does a coastal breeze make an evening walk safer?
No guaranteed benefit follows simply from being near water. Wind may transport as well as disperse smoke. Use NEA’s current measured reading and MOH personal guide, not the sensation of fresh air on the face.
Can a pregnant person attend a long outdoor concert during haze?
Assess current conditions, length of outdoor exposure, access to a suitable indoor alternative and personal health. A ticket or invitation does not override public-health or obstetric advice. Shorten, modify or postpone optional exposure when appropriate.
What if my workplace requires outdoor duties?
Discuss the actual job and personal health with your employer through suitable channels. MOM’s haze guidance addresses susceptible workers and outdoor exposure precautions. Individual medical advice and applicable workplace safety arrangements should inform the plan.
