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 […]
How Disrupted Circadian Rhythms Affect Stomach Function and Health
The circadian rhythm is a biological cycle lasting approximately 24 hours that synchronizes sleep, hormones, metabolism, and nearly all bodily functions. 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 […]
Circadian Rhythm and Diabetes Risk: What is the Connection?
Like all living beings, human physiological processes are influenced by circadian rhythms. The disruption of our internal clocks due to increasingly unbalanced lifestyles is directly linked to the explosive increase in type 2 diabetes cases. By what mechanism? A team from the University of Geneva (UNIGE) and Geneva University Hospitals (HUG) in Switzerland has lifted […]
