Sleep duration is a topic in which I have heard many different opinions. Some people say that 6 hours is good, other say that 8 hours; some other people say (at least I have heard) that the older you get the less sleep you need. I decided to investigate a little on the importance, rather than the hours needed, of a good night sleep and these are some facts I found.
Sleep helps your brain work properly. While you’re sleeping, your brain is preparing for the next day. It’s forming new pathways to help you learn and remember information. Studies show that a good night’s sleep improves learning. Whether you’re learning math, how to play the piano, how to perfect your golf swing, or how to drive a car, sleep helps enhance your learning and problem-solving skills. Sleep also helps you pay attention, make decisions, and be creative.
Your immune system relies on sleep to stay healthy. This system defends your body against foreign or harmful substances. Ongoing sleep deficiency can change the way in which your immune system responds. For example, if you’re sleep deficient, you may have trouble fighting common infections.
Getting enough quality sleep at the right times helps you function well throughout the day. People who are sleep deficient are less productive at work and school. They take longer to finish tasks, have a slower reaction time, and make more mistakes. After several nights of losing sleep—even a loss of just 1–2 hours per night—your ability to function suffers as if you haven’t slept at all for a day or two.
Bottom line is that we need a good quality sleep to replenish our brains and body to function properly the next day! Sleeping good is giving your body Jet Fuel!
