The Miracle Behind Sleep: What Does Your Body Do When You Fall Asleep?

We spend a precious time every night, that is, sleeping. However, have you ever wondered what your body does after you fall asleep? It turns out that sleep is not only for rest, but also for the repair and recovery of body organs.

1) Brain clears memory

Your brain accumulates a lot of information and memories during the day, but during sleep, it gets very busy. The brain's "scavenger" cells, called astrocytes, become active and clear away neuronal connections that are no longer needed, helping you filter and organize information so that you can think more clearly.

2) Cell repair and growth

The body's cells are damaged during the day for various reasons, but sleep is the golden period for cell repair and growth. During deep sleep, the body releases growth hormone to promote cell repair and growth, which is essential for wound healing, physical recovery, and the health of the immune system.

3) Strengthen the immune system

The immune system is also active at night. Sleep helps regulate the immune system and improves the ability to fight infection. If you lack sleep, your immune system may not respond effectively to pathogens, increasing your risk of getting sick.

4) Heart Health

Sleep also has a positive impact on heart health. Getting enough sleep can reduce your risk of cardiovascular disease because it helps maintain healthy blood pressure and blood sugar levels, which reduces the workload on your heart.

5) Regulate and relieve emotions

Sleep also has a profound impact on mood and mental health. A good night’s sleep can help relieve anxiety and depression, improve emotional stability, and allow you to face challenges more cheerfully.

In short, sleep is the body's "night engineer", performing various maintenance and repair work while you sleep, ensuring that your body and brain are refreshed when you wake up. Therefore, in order to stay healthy and energetic, do not neglect adequate sleep. Give yourself a precious rest time to allow your body and mind to fully recover.
