From UC Berkeley (June 4, 2020):
“We’ve discovered that fragmented sleep is associated with a unique pathway — chronic circulating inflammation throughout the blood stream — which, in turn, is linked to higher amounts of plaques in coronary arteries,” said study senior author Matthew Walker, a UC Berkeley professor of psychology and neuroscience.
Disrupted nightly sleep and clogged arteries tend to sneak up on us as we age. And while both disorders may seem unrelated, a new UC Berkeley study helps explain why they are, in fact, pathologically intertwined.
Some tips to improve sleep quality
- Maintain a regular sleep routine, going to bed and waking up at the same time each day.
- As part of a nightly wind-down routine, avoid viewing computer, smartphone and TV screens in the last hour before bedtime, and keep phones and other digital devices out of the bedroom.
- Engage in some form of physical exercise during the day.
- Get exposure to natural daylight, especially in the first half of the day.
- Avoid stimulants, like caffeine, and sedatives, like alcohol, later in the day.
UC Berkeley sleep scientists have begun to reveal what it is about fragmented nightly sleep that leads to the fatty arterial plaque buildup known as atherosclerosis that can result in fatal heart disease.
