Sleep is one of the most important factors in our physical and mental health. When we sleep the right amount of time every night, it has a positive impact on our daily lives and the way we feel. Experts agree that 8 hours of sleep is one of the best ways to improve our well-being, but what exactly happens to our bodies and minds when we sleep that much?

The amount of sleep each person needs varies, but most experts agree that adults need 7-9 hours of sleep per day. 8 hours of sleep is the one usually recommended, as it falls in the middle of this range and is associated with many beneficial effects on the body. However, sleep needs can vary depending on each person's age, genetic predisposition, and health status.

And that's why, although for most people, 8 hours of sleep is beneficial and not harmful, if you normally need less sleep, forcing yourself to get 8 hours can make you feel tired or even unhappy.

If you manage to sleep 8 hours every night, the benefits to your health will be manifold.

Recovery and rest

Sleep helps relieve the body of stress that has built up during the day. When you get 8 hours of sleep, your body and brain have the opportunity to fully recover, leaving you waking up refreshed and ready to face the next day rested.

Control your appetite better

Sleep affects hormones that regulate appetite, such as the one that triggers hunger. When we don't get enough sleep, this hormone increases, making us feel hungrier. In contrast, getting enough sleep keeps it at normal levels and helps regulate leptin, the hormone that sends a satiety signal to the brain.

Improves brain function

During sleep, the brain processes information and consolidates memories. It also helps clear out unnecessary information and stimuli, which leads to better concentration, memory, and decision-making. So, when we sleep well, our brain can function efficiently and respond more quickly to stimuli.

Strengthens the immune system

Getting enough sleep boosts the production of immune system cells that fight infection. This is especially important during the winter months, when viruses and infections are more common, as it helps the body better cope with illness and recover faster./ CNA
