Obstructive sleep apnea is a condition marked by brief pauses in breathing, often triggering loud snoring, grunts, gasps, and choking noises. Because sleep apnea can put stress on your heart and circulation, it's important to learn the signs and symptoms and get treatment.

Napping for  more than 30 minutes each day may be associated with increased risks for health problems. Causes of excessive napping include boredom, poor sleep at night, underlying conditions such as anemia or depression, medication side effects, dehydration, or malnutrition. Treating underlying conditions, staying hydrated, eating a healthy diet, becoming more active, and practicing good sleep hygiene may help reduce prolonged nap times.

There’s no evidence that maintaining a healthy lifestyle will suddenly boost the immune system. However, it’s clear that healthy lifestyle habits contribute to overall health, supporting the body’s ability to fight infections instead of creating new problems. Healthy habits that help maintain a robust immune system include getting seven to nine hours of sleep per night, exercising, reducing stress, eating a healthy diet, not smoking, drinking alcohol only in moderation, maintaining a healthy weight, and getting underlying conditions under control.
