A restless night often leads to fatigue the next day, but it can also indicate health problems that may not arise until much later. Scientists at Stanford Medicine and their collaborators have developed an artificial intelligence system that can examine the body signals from a single night of sleep and assess a person’s risk for […]
This Trick for the Brain Makes Exercise Seem Easier
Why are some people out of breath after a short jog, while others seem to glide along effortlessly? Training, fitness level, and muscle strength naturally play a role. Researchers have found that the brain also has a strong influence, especially on how strenuous physical activity is perceived. Sport challenges not only the body, but also […]

Older adults with weaker, more disrupted activity patterns were far more likely to develop dementia than those with stable routines. A later daily energy peak was also associated with a higher risk. The study points to the internal clock as a […]

The study, funded by the National Institute on Drug Abuse, found that 22% of Americans aged 19 to 30 reported using cannabis, alcohol, or both to help them […]

One study found that both conditions were associated with significantly lower numbers of NK cells—particularly the circulating types responsible for destroying infected or abnormal cells. As anxiety severity increased, NK […]
