Scientists used artificial intelligence to compare the MRI scans of 134 healthy young volunteers and found that those who were deprived of sleep for 24 hours or more showed signs of brain aging (loss of brain volume). and decreased activity of brain regions).
Specifically, the results show that total sleep deprivation increases predicted brain age by 1 to 2 years compared to actual age. However, following a night of recovery sleep, brain age returns to normal. These results suggest that total sleep deprivation affects brain structure in ways similar to aging, but that these effects are reversible with adequate sleep recovery.
The researchers also found that partial sleep deprivation had no significant effect on predicted brain age.
Sleep plays an essential role in the regeneration of our brain
This research highlights the importance of sleep for our neurological health. Sleep plays an essential role in the regeneration and proper functioning of our brain. During sleep, our brain rests, repairs itself and consolidates our memories.
Excessive fatigue can also have other negative impacts on health, as it can notably lead to weight gain, an alteration in the quality of the skin or even depression.
37% of French people are dissatisfied with the quality of their sleep
According to the INSV/MGEN 2023 survey, 37% of French people are dissatisfied with the quality of their sleep, the majority women (44%).
“At the same time, the average sleep duration of the French continues to decrease: they still sleep little during the week (6h58 on average vs 6h57 in 2019), while on weekends or during their holidays, sleep time has reduced of 34 minutes (7:40 a.m. vs 8:14 a.m.) due to earlier rising on Saturdays and Sundays (at 7:29 a.m.)”details the National Institute of Sleep and Vigilance.
