For years, scientists have been proclaiming the benefits of exercise. Studies showing that regular exercise benefits human health have exploded in number, examining many health problems ranging from cancer and diabetes to arthritis and pre-mature death.

Disease management programs that help guide the care of patients with chronic health problems appear to improve the quality of health care, but there is little evidence that such efforts actually save money, according to a study issued today by the RAND Corporation.

A new UC Davis study shows that a common antibacterial chemical added to bath soaps can alter hormonal activity in rats and in human cells in the laboratory—and does so by a previously unreported mechanism.

A Children’s Memorial Hospital researcher has developed a powerful and innovative health advocacy program that uses photovoice, a combination of digital photography and storytelling, to empower minority teens to identify and address important health problems in their communities.

A sweeping review of research studies of aspartame says there is no evidence that the non-nutritive sweetener causes cancer, neurological damage or other health problems in humans

In 2006, the World Health Organization issued a report that a critical shortage of doctors and nurses has contributed to severe health problems in Africa and parts of Asia.

Angiogenesis inhibitors that block a tumor’s development of an independent blood supply have been touted as effective cancer fighters that result in fewer side effects than traditional chemotherapy. However, a new study by researchers at UCLA’s Jonsson Cancer Center showed that one method of blocking blood supply development could result in serious and potentially deadly side effects.

Chronic sleep restriction has a negative effect on a person's cardiac activity, which may elevate the risk of cardiovascular disease and mortality, according to a research abstract that will be presented Wednesday at SLEEP 2007, the 21st Annual Meeting of the Associated Professional Sleep Societies (APSS).

Slow wave activity (SWA), a stable trait dependent marker of the intensity of non-rapid eye movement (NREM) sleep, is lower in young healthy African-Americans compared to Caucasians who were matched for age, gender and body weight, according to a research abstract that will be presented Tuesday at SLEEP 2007, the 21st Annual Meeting of the Associated Professional Sleep Societies (APSS).

Nurses who work the night shift are more likely to have poor sleep habits, a practice that can increase the likelihood of committing serious errors that can put the safety of themselves as well as their patients at risk, according to a research abstract that will be presented Monday at SLEEP 2007, the 21st Annual Meeting of the Associated Professional Sleep Societies (APSS).

Driving a vehicle requires coordination of horizontal eye movements and steering. A research abstract that will be presented Monday at SLEEP 2007, the 21st Annual Meeting of the Associated Professional Sleep Societies (APSS), finds that even a single night of sleep deprivation can impact a person's ability to coordinate eye movements with steering.

Children from a lower socioeconomic environment have worse sleeping patterns than children from middle class status. Excessive daytime sleepiness due to poor sleep the night before may have a negative impact on a child's academic performance and also put them at risk for developing health problems, according to a research abstract that will be presented Monday at SLEEP 2007, the 21st Annual Meeting of the Associated Professional Sleep Societies (APSS).
