While you sleep, most of your brain stays active, with about 20% in a restful state, helping your body recover and process information
When you sleep, it might seem like your brain is off and taking a break, but that’s not entirely true. In fact, your brain remains quite active, even though you’re resting. During sleep, your brain works on essential tasks like processing memories, repairing itself, and organizing information.
While you are asleep, about 20% of your brain’s activity slows down compared to when you’re awake. This means that 80% of your brain is still working, albeit in a different way. The brain goes through different stages of sleep, including light sleep, deep sleep, and REM (rapid eye movement) sleep. Each of these stages serves a unique purpose.
During deep sleep, the brain is less active, but this is crucial for physical restoration. Your body repairs tissues, builds muscle, and strengthens the immune system during this time. On the other hand, during REM sleep, the brain is highly active and involved in dreaming. For cognitive processes like memory consolidation and emotional control, this stage is crucial.
Overall, your brain doesn’t fully shut down while you sleep. Instead, it goes through various stages where it performs critical functions that help you feel refreshed and ready for the day ahead. So, even though you’re resting, your brain is busy at work, making sure you stay healthy and alert.
