Wooziness is often just a passing episode of lightheadedness. But it might signal something very serious, such as a stroke or heart attack. When wooziness occurs, one should sit or lie down for a few minutes, rest, and have a drink of water or juice. If wooziness eases, it's best to report the episode to your doctor. If lightheadedness hasn't improved or if it's accompanied by other symptoms, such as chest pain, trouble speaking, or weakness or numbness on one side of the body, call 911 immediately.

To reduce the pain of aching hip or buttocks muscles, one might consider stretching them. The activity makes muscles healthier and more flexible, which might keep them from pressing against nerves or bursae that can become inflamed and tender. It's best to stretch regularly with static stretches of the muscles at least three to five times per week, after a brief warm-up or a regular exercise routine. If hip or buttock pain flares, doing gentle stretches might ease discomfort in the moment.

In the summertime, one of the chief contributors to symptom flares of lung problems is hot air, especially if it's also humid, stagnant, or very dry. Such weather might narrow the airways, making it much harder to breathe normally. This might occur because hot air irritates the nerves, widens blood vessels near the lungs, or causes people to breathe faster. To avoid breathing difficulty, doctors advise people with lung disease to follow strategies such as keeping their inhalers handy and staying in air-conditioned spaces.

In a 2025 study of more than 85,000 people (average age 63), followed for six years, those who were the most active-even if they were simply doing light-intensity activities-had a 26% lower risk for cancer, compared with those who were least active.

In a 2025 study, researchers estimated that fewer than four emergency department visits attributed to semaglutide (Ozempic, Wegovy) occurred for every 1,000 patients taking the drug in 2022 and 2023. Most of the visits were related to gastrointestinal problems.
