Can We Ever Catch Up On Lost Sleep?

The old dogma on sleep is that we never catch on the lost sleep. People who did not have consistent sleep had the increased risk of hypertension, diabetes and Alzheimer’s disease.

Åkerstedt (Åkerstedt, et al. 2019) studied 44,000 people over 13-year period in Sweden. The researcher showed that people who tend to sleep less and catch up on weekend did not have increased risk of death than their counterparts.
