If sleep is not guaranteed for 8 hours, please guarantee at least 7 hours.

Editor’s note: Researchers at the University of Colorado at Boulder have found that sleep less than seven hours can affect overall physical health and increase the risk of stroke and heart disease. For most adults, 7 hours is a dangerous threshold. This article was translated from Medium, the original title is “What Happens When You Don’t Get Enough Sleep”, I hope to inspire you.
Insufficient sleep may be associated with a range of diseases, from heart disease, type 2 diabetes to obesity, depression, cognitive impairment, and even Alzheimer’s disease.
We know very little about why poor sleep can cause so much harm to physical and mental health. However, researchers are exploring the causes and mechanisms from blood vessels and brains.
According to a new study published in the journal Experimental Physiology, we can see the levels of three molecules that are thought to play a key role in vascular health in people who sleep less than 7 hours a night. 40% to 60% lower than normal. These molecules are called microRNAs, which inhibit the gene expression of proteins in cells, which were previously thought to be associated with inflammation and vascular health problems.
Christopher De, Professor of Integrated Physiology, University of Colorado Boulder Christopher DeSouza said: “They are like the brakes of cells, so if there is a lack of beneficial microRNAs, it will have a major impact on the health of the cells.”
DeSouza’s research is relatively small, including 24 men and women between the ages of 44 and 62. The study was based on self-reports and required subjects to fill out questionnaires about their sleep habits. As we all know, self-reporting may not be accurate because people may overestimate or underestimate their behavior.
