Most health experts around the world, a healthy adult should take at least 8 hours of sleep a day, it gives us a lot of relief. But have you ever thought that why we spend a quarter of a day sleeping? Sleep is necessary for good health. We need sleep to stay alive. Just like food and water are necessary for us. Let us know what is its connection with our health.
This biological process happens while sleeping
When we sleep, our brain stores new information and gets rid of toxic thinking. Our nerve cells do the work of communication and reorganization. During this time our body repairs cells, restores energy, and releases molecules such as hormones and proteins. All these processes are very important for our overall health.
Why is gold important to us?
We are still unaware of many reasons for sleeping, although its importance can be understood due to biological reasons. Let's have a look at them.
1. Energy Conservation
If we have to maintain energy in our body, then for this we need sleep. Sleep reduces our caloric needs. According to research, sleep reduces our daily energy requirement by about 35 percent.
2. Cellular Restoration
According to the Restoration Theory, our body needs sleep to restore itself. Sleep gives our cells a chance to repair and regenerate. The process of muscle repair, protein synthesis, tissue growth, and hormone release takes place during sleep.
3. Brain Function
Brain plasticity theory says that sleep is essential for brain function, specifically, it helps your neurons, or nerve cells, to reorganize. When you sleep, your brain's glymphatic (waste clearance) cleans the dirt of the central nervous system, which keeps accumulating throughout the day. It helps your brain to function well when you wake up.
4. Insulin Function
Insulin is a hormone that helps your cells use glucose, or sugar, for energy, but in insulin resistance, your cells don't respond properly to insulin. This can make your blood sugar level high and there is a risk of type 2 diabetes.
