A person sleeps for one-third of their lives. Most likely, this is connected to relaxing. However, our bodies and brains go through a number of crucial processes in addition to sleeping.

1. A decrease in body temperature.

Your body temperature drops a few degrees as you grow tired before going to bed, and it reaches its lowest point around two hours before you wake up. Your body thermometer is turned off by your brain during REM sleep, which is when you are most sensitive to the temperature of a room.

2. You can’t move your muscles.

Our entire body relaxes while we sleep non-REM, which results in a reduction in the total energy used by the body. The respiratory rate rises and the eyes actively move during the REM stage. The body is immobile throughout this time. We require this brief state of “paralysis” to ensure our safety. As a result, we never kick, push, or carry out the activities from our nightmares.

3. Your urge to urinate is eliminated by an anti-diuretic hormone.

The body’s water metabolism is controlled by the anti-diuretic hormone (ADH). The level of ADH in the body affects how much urine is produced. The body produces less urine when the hormone level rises. ADH concentrations are higher at night. This lowers the chance of urinating as you sleep.

4. Hormones aid in weight management.

Ghrelin and leptin, two critical hormones in our body, are controlled by sleep. Leptin aids in regulating satiety, while ghrelin regulates appetite. Limiting sleep might cause leptin levels to drop and ghrelin concentrations to rise. These adjustments may result in eating disorders and weight gain.

5. Stress levels decrease.

A hormone called cortisol aids in controlling our bodies’ levels of stress. Cortisol levels fall throughout the first few sleep hours. But as daylight draws near, this hormone’s level starts to rise once more. Since this is a natural process, the brain is getting ready to awaken in order to properly activate all the organs.

6. Daily information is sorted and processed by your brain.

Each person encounters a tremendous amount of information throughout the day. The brain transfers information from short-term memory to long-term memory as you sleep and processes all the information you have just been exposed to. This procedure aids in gathering the information for later usage into one place. Additionally, the brain purges unneeded information during in the REM state.

7. Your breathing and heartbeat become more relaxed.

During stage 3, non-REM sleep, breathing and heart rate drop and reach their lowest levels. The breathing speeds up and may even become erratic during the REM state. The pulse also accelerates at the same time, nearly matching the frequency of wakefulness.

8. Your body heals itself.


Our pituitary gland releases growth hormone while we sleep, which aids in the body’s repair of muscles, organs, and other cells. The immune system also creates unique cytokines proteins.
