Having an irregular dream is associated with 172 diseases

A pioneer international study has analyzed data Sleep objectives of 88,461 adults of the BIOBANCO OF THE UNITED KINGDOM and has found significant associations between sleep characteristics and 172 diseases.

The research, led by teams from the University of Beijing and the Army Medical University (both in China), and published in the magazine Health Data Sciencehighlights the regularity of sleep, such as constancy at bedtime and the stability of the circadian rhythm, as a factor little recognizedbut crucial, in the risk of disease.

Using actigraphy data during an average 6.8 yearsthe researchers identified that more than 20% of the risk of 92 diseases It was due to bad sleep habits. The irregular bedtime (after 00.30) was related to a risk 2.57 times Greater of Hepatic cirrhosiswhile low interdiary stability increased the risk of Gangrene 2.61 times.

In addition, the study denies the previous statements that Sleep a lot (about 9 hours) is harmful. While subjective reports have linked prolonged sleep with strokes and heart diseaseobjective data revealed this association only in a disease. An erroneous classification could be the cause: the 21.67 % from those who actually sleep they slept less than 6 hourS, which suggests that the time spent in bed is often confused with the real time of sleep.

“Our findings underline the importance, often ignored, of sleep regularity,” says the teacher Shengfeng Wangmain author of the study. “It’s time to expand our definition of good dream beyond simple duration“

The team confirmed several associations in US populations and identified the inflammatory ways as a possible Biological link. Future investigations will explore the causality and They will evaluate the impact of sleep interventions in the evolution of Chronic diseases.
