Sleep is more than just rest it’s a vital process that supports nearly every system in the human body. During sleep, the brain organizes and stores information from the day, the body repairs tissues, and hormones that regulate growth and appetite are released. There are different stages of sleep, including deep sleep and REM (rapid eye movement) sleep, each playing a key role in memory consolidation, emotional regulation, and physical recovery. Getting consistent, high quality sleep helps improve mood, strengthen the immune system, and enhance overall cognitive function.
Several factors influence sleep quality, such as light exposure, stress levels, and daily routines. Avoiding screens before bedtime, keeping a regular sleep schedule, and creating a calm sleeping environment can make a big difference. Most adults need 7 to 9 hours of sleep per night, though the exact amount varies by individual. Understanding the science behind sleep helps people make healthier choices that support long term well being and productivity. Shutdown123
