The optimal amount of sleep per night and the consequences of its absence Is it worth talking about the harm of not getting enough sleep? It's clear enough. Here's a more detailed guide to what happens to your body when you sleep: 0 hr - complete lack of sleep provokes microsleep (drowsiness) and memory lapses
1-2 hrs - cognitive functions such as concentration are impaired, and feelings of confusion and fatigue increase
3-4 hours - insulin resistance and blood sugar levels increase. Fat cells become 30% more sensitive to insulin and easier to grow
<5 hours - associated with 15% increased risk of death
5-6 hours - more energy burned from muscle and less from fat
<6 hours - increased feelings of hunger; weakened immune system and increased risk of catching an infection.
There is nothing more important than your body recovering fully - don't deprive yourself of rest in favor of late work or watching soap operas.
