An unexpected risk factor for heart disease has been identified

Irregular sleep has been linked to an increased risk of heart disease.

As reported by TUT.AZ with reference to foreign press, scientists have discovered an alarming pattern: a chaotic sleep schedule can double the chances of facing serious cardiovascular diseases.

In a large-scale study covering more than 3,200 middle-aged individuals, specialists tracked participants' sleep patterns over approximately ten years using wearable devices. They recorded how consistently people went to bed and woke up each day. During the observation period, 128 individuals experienced severe cardiovascular events — heart attacks, strokes, heart failure, as well as deaths related to the functioning of the heart and blood vessels.

The data obtained proved quite telling: people who went to bed at varying times had approximately twice the risk of dangerous complications compared to those who maintained a strict schedule. This pattern was particularly pronounced among participants who slept less than eight hours per night. Interestingly, fluctuations in wake-up times did not show a noticeable impact on heart health.

The study authors emphasize an important conclusion: what matters is not only the duration of sleep but also its regularity. According to the specialists, the habit of going to bed at the same time each night could become a simple and effective way to reduce the likelihood of cardiovascular problems.
