A lack of sleep is associated with a higher risk of being involved in a car accident. According to an analysis by the United States Traffic Safety Foundation, if you drive a car when you have slept less than five hours, you are 4.3 times more likely to be involved in a traffic accident. If you drive after only sleeping four hours, you are 11.5 times more likely to be involved in a car accident.
5) Hormonal health
A lack of sleep can affect growth in children and adolescents. Insufficient sleep may also affect fertility in men. According to a study published in 2013 in the American Journal of Epidemiology, men who do not sleep enough or who do not have enough quality sleep would have a sperm count of 29% less than those who regularly spend a good night’s sleep.
6) Sports performance
Insufficient sleep is associated with a decrease in athletic performance. Research indicates that a lack of sleep in athletes is associated with a lack of energy, poor post-workout recovery, a weakened immune system, increased risk of injury, and a lack of concentration during sports. A lack of sleep can also reduce the production of glycogen (which is the energy stores used during exercise) and muscle synthesis (building and repairing muscles).
