Getting enough sleep - sleeping throughout the night - is one of the keys to being emotionally, mentally, and physically healthy. Sleep deprivation or insomnia is associated with serious health problems such as obesity, depression, diabetes, and cardiovascular disease.
Insomnia, not falling asleep fast at night, disrupted sleep, snoring (yours or others), and waking up early are different types of sleep deprivation. Parents with small children know firsthand how hard it can be to get a good night's rest – and what the effects of sleep deprivation are!
Lack of Sleep is Connected to Depression and Low Self-Esteem
Sleep-deprived children have longer illnesses, more severe depression, and greater fatigue than those who aren't sleep deprived. Other studies link sleep deprivation with self-esteem problems. Getting good sleep and curing insomnia helps with fight depression and increase self-esteem.
Emotional well-being, performance, productivity, and mental abilities are all linked with the amount of sleep a person gets...so it's important to know how to fall and stay asleep at night.
Insomnia Doesn't Affect Physical Appearance
Alex Gardner of the British Psychological Society and emeritus professor of dermatology Ronnie Marks of the University of Wales found that sleep deprivation did not alter study participants' physical appearance. However, the study participants who were sleep deprived felt self-conscious about their appearance and thought their skin showed their lack of rest. They were convinced their looks were affected by their lack of sleep, even though they looked the same as when they were rested. Getting good sleep makes you feel better about yourself -- but doesn't change how you look.
Not Getting Enough Sleep Leads to Weight Gain
If you're losing sleep your body mass index (BMI) is likely to increase, and so is your waist circumference. Your risk of becoming obese is almost doubled, according to Professor Francesco Cappuccio of Warwick Medical School. He detected this trend in adults and kids as young as five years old. Getting good sleep can help you lose weight.
Sleep deprivation increases appetite through hormonal changes. Specifically, more of the appetite-increasing ghrelin is produced when you're not getting good sleep; less of the appetite-suppressing leptin is produced. Sleep deprivation and insomnia causes you to eat more.
Insomnia Leads to Memory Loss
Dr. Jeffrey Ellenbogen of the Harvard Medical School found that "sleep protects memories from interference." The more quickly you fall asleep after studying for a test or learning a new skill, the more likely you'll remember it later. If you learn new information and then go about your daily business, you'll have about a 44% lower chance of retaining what you've learned. This research could be particularly helpful when you're learning a new job. Getting good sleep helps your memory, while sleep deprivation damages it.
Sleep Deprivation Leads to Intellectual Impairment
Researchers at the University of Virginia have found that insomnia or lack of sleep can impair IQ and cognitive development in children. Lower grades and poor peer relations could also result from sleep deprivation. Getting good sleep increases cognitive ability and the ability to relate to others.
Exploring different natural sleep remedies can help reduce insomnia in both children and adults.
Lack of Sleep is Connected to Physical Impairment
According to the National Sleep Foundation, your body suffers when you don't get enough good sleep. Your coordination and motor functions may be impaired, and your reaction time may be delayed. You could have reduced cardiovascular performance, reduced endurance, and increased levels of fatigue because of sleep deprivation. Tremors and clumsiness can also result.
Never underestimate the importance of getting good sleep -- your home and work life could depend on sleeping soundly throughout the night!
