Pregnant people should also try to avoid spending time outdoors, especially those who are further along, Widmer said.
\"A lot of times, very pregnant people are carrying almost a large weight that sometimes can compromise their respiratory ability. And sometimes they feel short of breath at baseline. So very poor air quality could worsen that,\" Widmer said.
You should wear a mask that covers your nose and mouth, fits tightly to your face and can filter out smoke or ash particles before you breathe them in, according to the CDC. N95 or P100 masks can help protect your lungs from smoke or ash.
Those spending extensive time outdoors in smoky air or an ash-covered area should use a tight-fitting N95 or P100 mask to reduce exposure. Make sure the mask fits over your nose, under your chin and seals tightly to your face. Any leakage around your face will cause unfiltered air to enter and be inhaled, according to the CDC.
Because the particles are so small, Widmer said P100 masks may be more effective in filtering out the smoke particles. But an N95 mask is also a good option.
Wearing a mask while it is hot outside or you are physically active can increase the risk of heat-related illness. Make sure to take breaks often and drink water, according to the CDC.

When inside your house, choose a room closed off from outside air. You could set up a portable air cleaner or a filter to keep the air in this room clean even when it's smoky in the rest of the building and outdoors, according to the CDC.
Keep an eye out for any signs of illness in pets too, including trouble breathing, fatigue, coughing or gagging, red or watery eyes, nasal discharge, inflammation of throat or mouth or reluctance to eat hard foods. Call your veterinarian if you notice any of these symptoms develop.
The CDC advises people avoid using candles, gas, propane, wood-burning stoves, fireplaces or aerosol sprays and don't fry or broil meat, smoke tobacco products or vacuum.
Be on the lookout for coughing, wheezing, general shortness of breath and a general sense of not feeling well, Widmer said.
\"If you don't feel right, call your doctor,\" Widmer said.
