Health Benefits of a Good Night's Sleep

It’s a common knowledge that sleep, which makes up a mysterious part of your life, is beneficial for your body. When you don’t sleep for too long, you feel terrible and tired, and minor dark circles and eye bags appear around your eyes. Your brain is also affected and your vigilance is reduced, which increases the risk of human-error related accidents. To avoid these harmful effects of sleep deprivation, you need to sleep well. Some of the benefits of a good night's sleep are listed below.
  • Memory Improvement
Sleep helps you to consolidate new memories. During a normal slow-wave sleep (SWS), your body is resting, yet your brain is busy and is making connections between memories, events and sensory inputs. It makes you remember and process things better after waking up from a deep sleep, which may also give you a higher creativity.
  • Alertness
Sleep sharpens your attention. You feel energized, alert, vigilant and refreshed after waking up the following day, which means you can engage with things better during the day. That also means the chance for you to sleep healthy the next day also increases.
  • Healthy Weight
Sleeping for less than 7 hours within a 24-hour period may affect the balance of hormones in your body, which in turn may affect your appetite for food. That’s why you need to sleep well if you are interested in controlling your weight.
  • Body Repairs
Your cells produce more proteins while you are sleeping. These proteins are required for the modulation and maintenance of cellular activities. So sleep helps in body repairs.
  • Reduction in Depression
Depression is often found in people with a deficiency of serotonin, a neurotransmitter with a close relationship to the body’s sleep-wake cycle. Sleeping in a right amount can help you reduce depression.
  • Avoid Accidents
Insufficient sleep accounts for many single-car run-off-the-road crashes each year all around the world. Sleeping sufficiently in the night will make you avoid the risk for such fatal accidents.
  • Lesser risk of Death from Cardiovascular Disease
According to researchers from the University of Warwick and University College London, a lack of sleep increases the risk of death from cardiovascular disease by more than two times, but too much sleep also doubles the risk of death from cardiovascular and other diseases.  It all means you need a right amount of sleep to enjoy these benefits.
