Circadian rhythms are the body's internal "clock" that regulate various biological processes over a 24-hour cycle. It's true that factors like stress hormones, blood pressure levels, and changes in blood viscosity can contribute to the timing of heart attacks. However, the exact cause of this phenomenon can be influenced by a combination of genetic predisposition, lifestyle factors, and underlying health conditions. The mention of a gene variant affecting circadian rhythms and influencing mortality time is intriguing, as genetics can indeed play a role in an individual's natural sleep-wake cycle. Lifestyle choices, sleep habits, and overall health can also have significant impacts on the timing of health events and longevity.
