Negative Effects Of Sleep Deprivation



1. The desire to snack fatty foods increased

Lack of sleep can eliminate the hormone that regulates appetite. As a result, the desire to eat fatty foods and high in carbohydrates will increase. So cause you want a high calorie intake.

If you sleep for 2 nights is not of very can trigger excessive hunger. This condition occurs because the hormone ghrelin stimulates appetite, and reduce the hormone leptin as an appetite suppressant.

Over time, this can lead to weight gain. In a study conducted on identical twins by the University of Washington found that those sleeping 7-9 hours every night, the average body mass index of 24.8, almost 2 points lower than the average Body Mass Index (BMI) of their lack of sleep.

2. Antibodies to be weak

Based on the JAMA study, those who slept less than 7 hours per night could be 3 times more susceptible to cold. Another study found that in men who sleep less would fail to maintain the immune response or immune normally after receiving a flu shot.

Those who sleep less, antibodies that work after the vaccination only lasts a maximum of 10 days. The condition is very dangerous.

therefore, improve sleep quality, to boost your immunity. If too little time to sleep your immune system can be disrupted.


3. Vulnerable to diabetes

Sugar is the fuel of every cell in your body. If disrupted processing process can cause adverse effects. In a study by University of Chicago, USA, which examined a number of people for 6 days, get this condition can develop resistance to insulin, a hormone that helps transport glucose from the bloodstream into cells.

Those who slept less than 6 hours per night in the 6 days of this finding, a process of sugar metabolism improper. The result can cause the onset of diabetes.

4. Increased stress

Studies by the University of Chicago also found a 'blind eye' is less than 7 hours could increase the production of cortisol or stress hormones. Even in the afternoon and evening can increase heart rate, blood pressure and blood glucose that can lead to hypertension, heart disease and type 2 diabetes.


5. Trigger anxiety

Anxiety every night will definitely continue to haunt those who have poor sleep quality. The reaction of the body can be decreased. More chronic again, happy feeling will not live up to those who are sleep deprived.

"Sleep and mood set by the same brain chemicals," says Joyce Walsleben, PhD. This can increase the risk of developing depression, but perhaps only for those who are already vulnerable to disease.


6. Looks older

Those who sleep less usually have pale skin and tired face. "Even worse, increased levels of cortisol can slow the production of collagen which triggered the occurrence of wrinkles more quickly," said Jyotsna Sahni, MD, a sleep problem at Canyon Ranch, Tucson.


7. Various pain can arise

Not surprisingly, chronic pain such as back problems or arthritis may occur when you perform activities of poor sleep. In a study from Johns Hopkins Behavioral Sleep Medicine Program, director Michael Smith, PhD, wake healthy young adults 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.


8. Higher cancer risk

Exercise helps prevent cancer, but too little shut eye can damage the protective effect. Johns Hopkins Bloomberg School of Public Health study examining nearly 6,000 women for about a decade and found that sports fans who slept seven hours or less per night have a greater chance of 50% of cancer than those who routinely perform gymnastics and have a 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.
