Sleep is the natural recurring state of rest for both mind and body. It is accompanied with complete or partial consciousness of mind, reduction in bodily movement and less responsive to external stimuli.
Many people are often neglecting enough sleep because of the lack of knowledge on how sleeping is benefiting to their health. Sleep has remarkably improved a person’s health, performance and potential.
Good sleep depends on the quality of sleep. Without quality sleep, you will only spend more and more time sleeping but feel restless even after sleeping for many hours. So, quality sleep is very important to get enough sleep in a short period of time.
Why good sleep is important for good health?
1. Lack of sleep cause obesity:
when you are not taking enough sleep the level of leptin hormone that inhibits appetite decrease and increases the level of ghrelin hormone that increases the appetite and also reduces energy expenditure. This makes you eat more and more carbohydrate.
Leptin hormone is produced from fat. If you don’t sleep well, this production will decrease drastically and as a result, more fats will start storing in your body. Thus, lack of sleep can cause obesity.
Lack of sleep will also make you feel more tired and tends to skip your daily exercise.
2. Good sleep helps in weight loss:
Good sleep makes a person consume fewer calorie because of the production of high leptin hormone. This reduction in calorie consumption definitely helps in weight loss.
Good sleep also helps in burning more fats in the body.
3. Poor sleep can cause cancer:
Sleeping for only 4-5 hours daily is not enough. Short sleep reduces the number of anti-cancer immune cells from the body. As a result of this, the risk of developing numerous types of cancer is increasing.
Even the World Health Organization has decided to classify nighttime shift work as a probable carcinogen because it disrupts the sleeping order of a person.
4. Insufficient sleep can cause diabetes:
Consistent evidence has shown that prolong sleep loss results in impaired glucose metabolism and decrease insulin sensitivity. Due to this, the level of sugar in the blood increase.
The report also found that people who sleep less than 6 hours daily have a high risk of causing type-2 diabetes.
5. Reduce cardiovascular disease:
Taking good sleep daily reduce the chances of causing cardiovascular disease. Good sleep helps in balancing one’s heartbeat rate and as a result, it helps in balancing blood pressure.
If one takes poor sleep, the blood pressure will rise and there will arise the chance of having a fatal heart attack or stroke.
6. Improve physical performance:
Sleep has a direct impact on physical performance. Good sleep is a part of the recovery from physical tiredness, injury and illness. It also increases the energy level in the body. Thus, increase a person’s physical performance.
For athletes, an increase in sleep duration and sleep quality will help in achieving their desired goal.
7. Effects on the brain due to a prolonged lack of sleep:
Prolonged lack of sleep prevents the brain from learning and storing new lessons and memories. Because of this, one will become unable to have experience in new memories.
Lack of sleep also tends to produce a more toxic protein in the brain and as a consequence of it, one can suffer from Alzheimer’s disease and dementia.
8. Good sleep helps in reducing stress:
Good sleep is one of the most effective ways of reducing stress. Persons who sleep less always have the risk of causing mental stress. This disturbs their physical and mental health.
Consistent stress for a long time can cause many chronic diseases and also can develop premature ageing to a person.
9. Boost the immune system:
Adequate sleep helps a person in well functioning of all body organs and maintain a proper balance in biological metabolism. Good sleep is important for producing anti-disease cells and defend from so many possible diseases.
A weak immune system is prone to more diseases. So, one must sleep at least 6-7 hours daily at night. Sleeping in day time will always give you insufficient rest that your body requires for well functioning.
10. Poor sleep can cause inflammation:
Older people have more risk of causing inflammation than younger people because of the disturbance in sleeping pattern of older people increases with age.
Some of the diseases caused by inflammation include cancer, cardiovascular disease, stroke, type-2 diabetes, Alzheimer’s disease, autoimmune disorder etc.
A night of good and quality sleep is one of the best way for reducing inflammation in the body.
