Giant study: The link between night dreaming and reduced risk for over 1,000 diseases

Detailed summary

Sleep patterns of about 95,000 people were examined, and it was revealed that deep sleep was linked to fewer diseases while fragmented sleep was linked to an increased risk for many diseases.

We are used to asking how many hours we slept at night, but a new study claims that this number is only part of the story. The time we spend in the various sleep stages, the number of awakenings, and the differences from night to night may also be linked to health in the coming years.The researchers analyzed data from 95,559 participants in the British database UK Biobank, who wore a smartwatch on their wrist for seven consecutive days and nights. Afterwards, they tracked their medical records for a period of about 9 years and examined links between sleep characteristics and the emergence of 1,049 diseases and medical conditions.The result was a vast map of statistical connections.
