Few nights of bad sleep increases risk of heart attack and stroke
- Swedish researchers examined the impact of several consecutive nights of limited sleep on proteins related to cardiovascular disease risk in 16 healthy young men within a controlled laboratory setting.
- The study aimed to clarify mechanisms by which lack of sleep could increase heart attack or stroke risk, as past research mostly focused on older at-risk individuals.
- The team measured about 90 blood proteins and found that many related to inflammation and cardiovascular risk rose after sleep deprivation even in young healthy men.
- Dr. Jonathan Cedernaes explained that the body’s reaction to exercise varies somewhat after sleep deprivation, and while exercise can help mitigate certain negative impacts of insufficient sleep, it cannot substitute for the vital benefits of a full night’s rest.
- These findings suggest that insufficient sleep promotes molecular mechanisms increasing cardiovascular risk early in life, and further research is needed on diverse populations and sleep patterns.

Columbia students report sleep problems, but is weed the answer?
For two weeks before midterms this semester, Riley McGuire, a sophomore fine arts major, barely slept three hours a night. That wasn’t unusual, she said, because she has struggled with sleep for years. She was prescribed sleep medication five years ago, but it made her feel drowsy the next day. “I’d rather not sleep at all than sleep well, then be too tired when I wake up,” McGuire said. She tried smoking weed more than a year ago, but she …
