4 Benefits of Getting Enough Sleep

4 Benefits of Getting Enough Sleep

  1. Improved memory- New memories will stay for longer periods of time if enough sleep is had. This is due to activation of brain regions changing while sleeping. It is thought that these memories shift to areas of the brain that are better at storing and accessing memories [1].
  2. Increased weight loss- Those who are sleep deprived have been shown to intake 385 extra calories a day when compared to people who have a had a sufficient amount of sleep [2]. This is believed to be caused by a change in the timing of hormones released in the body. More specifically hormones that are responsible for hunger and satiety could be altered [3]
  3. Improved cardiovascular system- 7 hours per night is the recommended amount of sleep per night. Those who get less can experience symptoms that can lead to coronary heart disease [4].
  4. Improved immune system- There is a greater chance of getting sick when sleep deprived due to the decrease in lymphocytes and monocytes that are at their high point while sleeping, and the decrease in various hormones that release while asleep[5].
