Does catching up on sleep during weekends really compensate for fatigue and physical damage accumulated during the week? According to foreign reports, a recent study found that just a few days of sleep deprivation can have negative effects on the body. While weekend sleep recovery may moderately reduce tiredness, the damage caused by weekday sleep deprivation persists.
Sleep Deprivation May Worsen Chronic Inflammation
According to the UK's *Daily Mail*, existing research shows that a few days of sleep deprivation can lead to chronic inflammation and impaired blood sugar regulation, directly affecting bodily functions. Weekend sleep recovery sounds like an appealing plan, and many people prefer this approach.
However, a U.S. study found that weekend sleep recovery cannot make up for weekday sleep deprivation. The study pointed out that while weekend sleep may moderately reduce fatigue, the lack of focus and physical damage caused by sleep deprivation will still persist.
Researchers from the University of Pennsylvania Hospital recruited 30 volunteers for a week-long test. They first restricted the participants' weekday sleep and then allowed them to sleep more on weekends. At different time points, their physical functions were tested.
The researchers found that participants' sleepiness increased after restricted sleep but decreased after weekend recovery. Similarly, inflammatory responses in the blood rose during sleep restriction and dropped after recovery. However, attention tests showed no improvement even after recovery sleep.
The results emphasize that a short weekend of extra sleep cannot reverse the damage caused by staying up late or sleeping insufficiently during the week. Maintaining regular sleep daily is the only way to keep the body free from disease threats. The study has been published in the *Journal of Physiology* by the American Physiological Society.
