Obstructive sleep apnea (OSA), marked by breathing pauses during sleep, is linked to high blood pressure, heart disease, stroke, and diabetes. A 2025 study found that people at high risk for OSA also had about 40% higher odds of depression and other mental health conditions.

Certain strategies can help people avoid flare-ups of diseases that seem to be affected by cold weather. For example, people with psoriasis can ward off dry skin (which causes flare-ups) by taking short, lukewarm showers, using a humidifier at home, and moisturizing with cream-based emollients. People with asthma should try to do outdoor activities during warmer parts of the day, take a puff of a rescue inhaler before going out, and wear a mask when outdoors. And people with arthritis can exercise and try heat therapy.

People with asthma should be aware of seemingly harmless substances, such as wood smoke and candle scents that could worsen symptoms such as coughing, chest tightness, wheezing, and shortness of breath. They should also get vaccinated against viral infections, see a specialist if necessary, keep watch for signs of a flare, and create a plan with their doctor to address flare-ups, which send millions of Americans to hospital emergency departments every year.
