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 […]
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 […]
Why Unknown Sleep Disorders are Often Stressful
Unknown sleep disorders are sleep problems for which no clear cause can initially be identified. Those affected sleep poorly, wake up frequently, feel exhausted in the morning or experience unusual nocturnal symptoms – and yet, after initial examinations, neither organic diseases nor typical sleep disorders such as sleep apnoea, restless legs or hormonal changes can […]
Can Sleep Deprivation Have an Antidepressant Effect?
Most people who have ever pulled an all-nighter are familiar with this feeling of “exhaustion and overexcitement.” Although the body is extremely tired, the brain feels euphoric, dazed, and almost dizzy. Neurobiologists at Northwestern University were the first to discover what causes this “punch-drunk” effect. In a study, the researchers induced mild, acute sleep deprivation […]
