@biosaber52: What happens to your brain after 24 hours without sleep? After approximately 24 hours of wakefulness, attention, reaction speed, working memory and other cognitive functions decline. The drive to sleep increases, partly because adenosine accumulates during wakefulness. Microsleeps can also occur: brief, involuntary episodes in which the brain partially enters a sleep-like state. Prolonged sleep deprivation can significantly impair performance and the ability to make decisions. #medicine #brain #sleep #science #tiktokgrowthchallenge
