झोप दररोज रात्री तुमचा मेंदू स्वच्छ करते

Just as workers clean busy streets before morning traffic, sleep cleans your brain every night.

Many people think, "If I get eight hours of sleep, I will feel great." But this is not always true. Compare sleep to washing clothes in a washing machine. If the machine stops mid-cycle, the clothes remain dirty even after hours inside it. Similarly, your brain needs complete sleep cycles to properly clean and repair itself.

Each night, the brain typically goes through four to six cycles of sleep. Each cycle lasts about 90 minutes. During deep sleep, something remarkable happens: the spaces between brain cells get bigger, and fluid flows through the brain washing away waste products.

Scientists have found an important waste protein called beta-amyloid. Excessive amounts can cause diseases like Alzheimer's, which affects memory and thinking. Deep sleep helps remove this waste.

Another stage of sleep helps with memory. The brain sorts important information, as if arranging books in a library. Things you learn and skills you practise are stored more securely. That is why good sleep helps students remember lessons better.

The biggest lesson: the quality of sleep is just as important as the amount of time you sleep. A cool, dark room, minimal screen time before bed, calm breathing, and a regular sleep schedule help your brain get its important work done at night.
