Hello there! :D
Wow, there’s a lot of reasons for why sleep is so crucial to the body and mind but I’ll keep it short and sweet!
For one reason, sleep is the most stimulating source of energy and the most natural. Secondly, it’s vital for the brain to get up to at least eight hours of sleep for proper development. Lastly, functioning off of little to no sleep while doing daily life activities can be extremely harmful and dangerous, for example like driving, cooking, etc.
