Little sleep is not recommended because it has a harmful effect on health, but too much sleep also affects it.
British researchers determined the impact of sleep hours on metabolism:
12 hours A study published in the journal Sleep found that sleeping this number of hours increases your chances of becoming obese by 25 to 35 percent.
10 hours You will improve your sprint times eight percent, according to researchers at Stanford University in the United States. They will also improve your reflexes.
8 hours A study published in the Journal of Clinical Investigation found that growth hormone (GH), responsible for repairing muscles, is released during sleep. Therefore, the more you sleep, the higher the dose of GH.
6 hours If you train and have not slept enough, the muscles will not receive the stimulus they need to grow, researchers in the California State University in the United States warn in a recent study.
Less than 4 hours Your resistance will decrease between 15 and 40 percent, according to a study published in the European Journal of Applied Physiology and Occupational Physiology. In addition, you will be in a very bad mood.
