Sleeping well helps to strengthen the body's ability to fight infections by helping to stay healthy because during sleep the body produces extra proteins that help the immune system to get stronger, especially in stressful situations.
Other benefits of a good night's sleep include:
1. Reduce stress
During sleep, the body decreases the production of cortisol and adrenaline, helping to decrease stress.
2. Control appetite
Sleep helps regulate hormones that affect and control appetite, so when you sleep poorly, these hormones become deregulated and your appetite increases, leading to a craving for foods rich in calories, fats, and carbohydrates.
3. Improve mood
People who sleep well at night, walk happier and happier during the day. On the contrary, a night of insufficient sleep causes restlessness and malaise the next day. Also, when sleeping poorly becomes a chronic problem, it can cause long-term mood disorders such as depression or anxiety, for example.
4. Activate memory
Sleep well allows the brain to better process new experiences and knowledge, improving memory. During sleep, the brain processes and consolidates the memories of the day, so badly sleeping nights can cause new information not to be stored properly, damaging the memory.
5. Stimulate reasoning
Poor sleep affects cognition, attention and decision making, so people who sleep poorly have greater difficulty solving problems of logic or mathematics and making mistakes like leaving keys in the refrigerator by accident, for example.
6. Rejuvenate the skin
A good night's sleep helps to rejuvenate the skin, reducing wrinkles and lines of expression, because at night the skin cells renew and rest and is produced melatonin that helps prevent aging.
