Whether you have imagined it or not,  we spend around a third of our lives (around 25 years) sleeping. A good 8 hours of sleep helps us to recover from the previous day’s exertions and prep for a new day. But do you know what actually goes on while you’re conked out?

Your Brain Is Active

Our brains are “on” throughout the night. The brain is actually very active during sleep doing important things. According to a study, the brain is processing the information we gained during the day and shutting out the information we don’t need.

 

Your Heart Rate and Breathing Slows Down

Physiological processes during bedtime slows down and so does your breathing and heart rate.Also the liver quites down from trying to detoxify.

And so does your body temperature

While we sleep, core temperatures drop a bit. Furthermore, keeping your room cool before bed can help you sleep better.

Your blood pressure plummets

Total body relaxation leads to something called a “nocturnal dipping” of your blood pressure. It’s normal for people if the blood pressure can drop by about 4 to 7 points while you are having  a good night’s sleep.

You pump out growth hormones

We’re talking about HGH, or human growth hormone which is a protein that fights aging and injury for which you need to sleep deep for seven to eight hours. Even if you’re not growing taller, you’re always growing: building muscle cells.

 

When it comes to staying healthy, we put a lot of attention nutrition and fitness, which are both very important. But we should put sleep on that same level.
