Why do People Sleep So Much in Their Lifetime?

We feel tired because of the excessive accumulation of a toxin named “Lactic acid”, due to which we feel the need to sleep. After we sleep, this toxin disappears and we feel quite energetic.

Following are the reasons why we need to sleep:

  1. Full brain function- Lack of sleep may result in low brain functioning, i.e., troubles in recalling and concentration. After a good sleep, your brain is refreshed and helps in storing new and recalling older information, improves our decision-making, and decreases error-making.
  2. Good mood- Getting enough sleep will help you to reduce stress, anxiety, irritability, or any other emotional problems. It’ll surely put you in a good mood, and help you in being optimistic throughout the day.
  3. Proper fitness- Believe it or not, but sleep also helps you in weight control. Lack of sleep may result in hormonal imbalance, which is responsible for controlling appetite. This may lead to overeating or the temptation to eat unhealthy food. A night of good sleep will work towards maintaining the balance between your hormones and appetite.
  4. Improved immune system- Lack of sleep may cause serious issues of diabetes, memory loss, hallucinations, trembling hands, and high blood pressure as well. That is why human beings need to sleep.
