sleep facilitates much more than physical rest. It allows us to carry out essential repairs and maintenance. It giving us a chance to ‘reboot’ our internal hard drive and ditch those unnecessary bytes of data we carry around.
it’s still not entirely clear why human beings want to sleep. However,
We must widely accepted that during sleep we were physically and mentally inactive. However ,Now we know, it is not true. We also know that right through the night, all kinds of stuff to keep you in tip-top health is going on.
Repairs in progress
During the deep sleep phase, Our Muscles, organs and other cells are lovingly repaired. chemicals vital for strengthening our immune system coarse through our blood. So when you wake up and you say “what a great night’s sleep – I feel like a new person”,
Taking out the trash
REM sleep is a kind of ‘trash dumping’ mode. During this phase, brain discards useless information. So after sleep, humans are significantly better at solving puzzles, it help to remembering facts or how to carry out complex tasks.
Let’s get physical All beings go through a sleep cycle. Typically, we move through all its stages several times a night. When we move from moderate to deep sleep. brain activity slows down.
After this stage, the brain starts to become more active again. It entering the REM stage & It help to pop up most of our dreams .
Did you know that as we get drowsy just before bedtime, our body temperature drops by a couple of degrees?
Our body temperature reaches its lowest point around two hours before waking. that in REM sleeping stage, the brain switches off the body’s thermometer.
We assume that when we sleep, we breathe at the same rate all night.It is not true. When we enter deep sleep, breathing slows down. It takes on a more regular pattern. When the REM phase starts, our breathing speeds up again. we also experience variation in breathing rates.
when you first close your eyes and start to drift off into non-REM sleep,
brain activity levels start to tail off. Our brains ‘fire’ in a more regular pattern. The peace doesn’t last though.When we enter the dream phase, your brain does a little electrical dance with lots of activity. In fact, brain activity in this phase looks remarkably similar to when we’re awake.
You’ll be pleased to hear that deep, non-REM sleeping stage is like balsam for our pulse and blood pressure.
All the stresses and strains of the day are left behind and our poor blood vessels grab a few precious minutes of recovery time.
