Extreme heat brings a jump in emergency room visits by adults of all ages, a new study shows.

While it's well known that extreme heat puts adults aged 65 and older at increased risk of hospitalization and death, it's been less clear how it affects young and middle-aged adults.

To find out, the researchers analyzed the associations between heat and ER visits among more than 74 millio...

Singing in a choir may be good for your soul, but it can also spread COVID-19 far more easily than conversation does.

A new study also found that the louder and person sings or talks, the more particles are spewed into the air, and that more particles are released by men than women, and by adults than children.

Fears that airborne transmission of COVID-19 could pose a risk to p...

It's probably fair to say that most people know of the so-called "Freshman 15" -- the weight that college students are often said to gain when they're away from home for the first time.

But in recent decades, matters have gotten much worse in the United States. A new study using national data for people aged 18 to 25 found that while the prevalence of obesity was just over 6% in 1976 to 1...

While climate change gets a lot of notice for its numerous negative impacts around the globe, children's allergies may not be among them.
