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 […]
Anxiety and Insomnia are Associated With a Sharp Decline in Important Immune Cells
Natural killer cells act as the immune system’s rapid response team, but stress caused by anxiety and insomnia can reduce their numbers without anyone noticing. 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 […]

While many people associate the “internal clock” primarily with the brain, the stomach also plays a central role in this timing mechanism. In fact, there is a bidirectional connection: the circadian rhythm influences stomach […]
