I recently read Matthew Walker, PhD #book "Why We Sleep" & it led to some stunning discoveries about sleep that i share via #sketchnote & below:

-#Sleep is not a dormant state.There are some parts of your brain that are up to 30% more active during sleep relative to when you are awake.

-There are two stages of sleep that we cycle- Non Rapid Eye Movement (NREM) sleep & Rapid Eye Movement (REM) sleep.

-If you get up 2 hours earlier (~8 hrs sleep), you may think that you have lost 25% of sleep, in reality, you may have lost 70-80% of REM sleep.

-REM sleep can increase your problem solving capacity. In REM sleep, there is an information alchemy where the brain starts to collide all the things it recently started learning with the pre-existing knowledge.

-NREM stage 2: Important for learning and memory.

-NREM stages 3,4: Important for keeping immune system healthy, help with our cardio-vascular system. It is the best form of blood pressure medication.

Sleep is not an optional lifestyle luxury. Sleep is a nonnegotiable biological necessity,something that needs as intense prioritization as does our work & family time.
If managed well,for all it's benefits,it can be your greatest competitive advantage and a true super power.
