Things You Never Knew Your Body Does While You Sleep:

1. You Lose Weight

According to Womansday, you lose water breathing out humid air and through perspiring during the night. This happens during the day too, but drinking and eating, while you are awake negates any weight loss.

If you are getting just 4-5 hours of sleep per night, you could be canceling out whatever exercise and diet choices you are making during the day. To reduce your waistline, get at least 7 hours of sleep per night.

2. Your Body Temperature Goes Down

Your body temperature goes way down. When you are active during the day, you are burning more calories, so, lowering temperature is a way to save calories and reduce the burn rate .

According to Dr. Avi Ishaaya, assistant clinical professor of medicine at UCLA and a sleep specialist, “Sleep is a survival mechanism.”

3. Your Blood Pressure and Heart Rate Decreases

When you are resting, your body does not need to pump as much blood or work as hard, so these systems slow down. Blood pressure needs to go down at night, giving your circulatory system and cardiac muscle time to relax and repair.

It is important for individuals with high blood pressure to get at least 7 hours of sleep to experience that temporary drop, as it reduces the risk for heart disease. If you are suffering from sleep apnea, get treatment because that condition can increase nighttime blood pressure.

4. You Dream

If you have awoken after a vivid dream, then you are familiar about the vague unease of wondering if it was real. Despite much research into dreaming and so many hypotheses about why we dream and these dreams mean, these everyday occurence are still a mystery.

Scientists have not yet determined why we dream as we do, or found a proven process that would explain the content of the dreams.

5. You are Paralysed for a Bit

In REM sleep, the dreamy state of the sleep cycle, the muscle groups become paralysed to prevent you acting out your dreams. Sleep scientists call this atonia, which is important because in this state your brain is active, and your eyes are darting creepily from side to side.

When atonia does not work, you can experience some interesting phenomenon such as sleepwalking. And when atonia works but your brain decides to awake, you experience the mind-body mash-up that is known as sleep paralysis.

6. Produces Human Growth Hormone

Total-body relaxation results in what is cHuman growth hormone, or hgH, helps the bone, muscles, and other tissues regenerate. The helpful hormone is released while you sleep, most especially its deepest stages, and is thought to be prompted by low blood glucose levels present during sleep.Therefore, there is some science behind the concept of beauty sleep.

7. Slows Down Your Kidneys

Kidneys function normally to filter toxins out of the bloodstream, therefore producing urine. As you sleep, the filtering action of the kidneys slow down, so that less urine is produced. This is the reason your urine is usually so dark, the first time you pee in the morning.
