Irregular Sleep Patterns Linked to Increased Cardiovascular Risk
A study involving over 3,000 middle-aged adults has found that consistent bedtimes are associated with a lower risk of major cardiovascular problems, such as heart attack and stroke. Conducted over nearly a decade, the research used wearable devices to track participants' sleep patterns. It revealed that irregular bedtimes and variable mid-sleep times significantly increase the risk of cardiac events. Conversely, getting more than eight hours of sleep per night appeared to mitigate heart issues. The study suggests that regular bedtimes may be crucial for heart health as they align with the body's circadian rhythms, which govern vital processes. Additionally, a separate study highlighted that fluctuating sleep apnea severity could impose strain on the heart, linking severe apnea and habitual snoring to faster vascular aging.
