Exercise Boosts Brainpower After All-Nighter
3 Sep
Summary
- Exercise or a short nap can help mitigate sleep deprivation effects.
- Cognitive performance improved significantly after exercise or naps.
- Exercise aids memory recall by making brain resources more efficient.
Sleep deprivation, affecting one in three adults globally, has detrimental impacts on physical and mental health. However, new research from McGill University suggests that exercise or a short nap can help mitigate these effects. A study supervised 54 healthy young adults who were kept awake for 30 hours.
Participants were then divided into three groups: one group cycled for 20 minutes, another napped for 90 minutes, and a control group did nothing. Memory recall tests conducted three days later revealed that those who exercised or napped performed approximately 22% better on memory tasks than the control group.
While napping aided the brain in absorbing new information, exercise helped the brain utilize its available resources more effectively. Researchers highlight that exercise is an accessible and inexpensive method to maintain cognitive sharpness during periods of limited sleep, offering practical applications for fatigue-management strategies in demanding work environments like healthcare.
