When you have a good sleep quality, then all the body activities and activities of everyday life will go smoothly. Conversely, if You have a poor sleep quality, a variety of negative effects appear. Here’s 8 bad effects that can impact your body if you sleep less than 7-9 hours / day, and if you do not sleep soundly.

1. Increasing the desire to eat fatty Foods

Lack of sleep can eliminate the hormone that regulates appetite. As a result, the desire to eat high fat and carbohydrates will increase. You want to eat a high calorie intake. If during the 2 nights you are not sleep soundly, It can trigger excessive hunger. This condition occurs because the ghrelin hormone stimulates appetite enhancer, and lessen leptin hormone as appetite suppressant.

Over time, this can cause weight gain. In research done on identical twins by the University of Washington found that People that sleep 7-9 hours every night, the average body mass index was 24.8, almost 2 points lower than the average Body Mass Index (BMI) of those who lack of sleep.

2. Weaken the body’s antibody

Based on the JAMA study, people who slept less than 7 hours per night could be 3 times more prone to feeling cold. Other research found that in men who sleep less will fail to maintain the immune response or a normal immune after receiving a flu shot. The people that get lack of sleep, antibodies that work after the vaccination only lasts a maximum of 10 days. This condition is very dangerous.

Therefore, improve the quality of sleep, to boost your immune system. If too little time to sleep your immune system could be disrupted.

3. Vulnerable to diabetes

Sugar is the fuel of every cell in the body. If the processing process disrupted, It can cause bad effects. In a study by the University of Chicago, It examined a number of people over 6 days. This condition can develop resistance to insulin, a hormone that helps transport glucose from the bloodstream into the cells.

The study found that sleeping less than 6 hours per night in 6 day can cause inapproriate process of sugar metabolism. The result can cause diabetes.

4. Increasing stress

5. Triggering restless

Sense of restless every night would continue to people who have poor sleep quality. The reaction of the body can decreasing as well. More chronic again, happy feelings will not live up to people with lack of sleep. “Sleep and mood is regulated by the same chemicals in brain,” said Joyce Walsleben, PhD. This can increase the risk of developing depression, but perhaps only for those who are vulnerable to the disease.

People with lack of sleep usually have pale skin and tired face. “Even worse, increased levels of cortisol that can slow the production of collagen which triggered the wrinkles more quickly,” said Jyotsna Sahni, MD, a sleep problem expert at Canyon Ranch, Tucson.

7. Various pain can arise

Not surprisingly, chronic pain such as back problems or arthritis can happen when you make a bad sleep activity. In a study from John Hopkins Behavioral Sleep Medicine Program, director Michael Smith, PhD, waking healthy young adults people for 20 minutes every hour for 8 hours for 3 consecutive days. The result, they have a lower pain tolerance, and easy to experience pain.

various pain can arise

8. Higher Cancer Risk

Exercise helps prevent cancer, but too little closing eyes can damage the protective effect. Johns Hopkins from Bloomberg School of Public Health study examined nearly 6,000 women for about a decade and found that sports fans who slept 7 hours or less per night have a greater chance of 50% have cancer than those who do exercise regularly and have good sleep quality .

Because the poor quality of sleep can cause hormonal and metabolic disturbances associated with cancer risk, and can ‘delete’ the benefits of exercise.
