6 Diseases that often occur in people who often stay up late

You must have felt sleep deprivation. Sleep only a few hours because you have to stay up late doing college assignments, office assignments, or other reasons. The next day, you will feel sleepy throughout the day, feel weak, lack of focus, lack of enthusiasm, or your mood becomes not good so you get angry easily. Many people do not realize that it all happened because of lack of sleep at night. 

Not only affects the next day, lack of sleep can also have an effect on health in the long term. 

The risk of lack of sleep for health

Lack of sleep is associated with chronic diseases, such as diabetes, high blood pressure, and heart disease. Several studies have shown a link between sleep habits and disease risk. 


Lack of sleep can increase the risk of weight gain. Research shows that people who sleep less than 6 hours per night have a higher Body Mass Index (BMI) and people who sleep 8 hours per night have the lowest BMI. BMI is a measure of a person's body is said to be thin or fat based on their height. The fatter his body, the higher his BMI. 

Lack of sleep is associated with increased hunger and appetite, leading to weight gain and obesity. During sleep, the body produces hormones that help control appetite, energy metabolism, and glucose processing. Lack of sleep makes the work of these hormones and other hormones disrupted. 

Lack of sleep is associated with hormones that regulate appetite, namely lower levels of leptin (a hormone that stimulates satiety signals to the brain) and higher levels of ghrelin (a hormone that stimulates hunger signals to the brain). So, lack of sleep makes the body feel hungry, even if we have eaten. 

Lack of sleep can also increase the production of the hormone cortisol or stress hormone and is also associated with increased insulin production. Insulin is a hormone that regulates glucose and fat storage. High insulin levels are associated with weight gain, a risk factor for obesity. 

Type 2 diabetes mellitus 

Lack of sleep is associated with the risk of type 2 diabetes mellitus. Research shows that lack of sleep can increase the risk of type 2 diabetes mellitus because it affects the work of glucose in the body. Research that reduces sleep time in healthy people from 8 hours to just 4 hours per night shows that their bodies process glucose longer than if they slept for 12 hours. During sleep, the body continues to process glucose to maintain blood sugar levels. 

Heart disease and hypertension 

Lack of sleep can contribute to a rise in blood pressure. Research shows that just one night of people who have hypertension (high blood pressure) lack of sleep, can cause their blood pressure to rise in the following days. This impact can develop into heart disease and stroke. People who already have hypertension should sleep enough at night so as not to aggravate the disease. Other studies have shown that sleeping too little (less than 5 hours) and sleeping too much (more than 9 hours) can increase the risk of coronary heart disease in women. 

Mood disorders

Just one day of lack of sleep at night can cause you to be irritable and moody the next day. Long-term sleep problems, such as insomnia, are linked to depression, anxiety, and mental stress. Research conducted on 10,000 people showed that people with insomnia were five times more likely to become depressed than those without. 

Another study reported that people who slept 4.5 hours per night showed more feelings of stress, sadness, anger, and mental exhaustion. People who slept 4 hours per night also showed a decrease in optimism and sociability. It is also reported that all these effects of sleep deprivation can be overcome when the person returns to normal sleep duration. 

Decreased immune function 

When you are sick, you will usually be advised to sleep more. Sick people who seep more are better able to fight off infection than those who sleep less when sick. The body produces more immune cells to help fight infection when sick. This harder body work causes the body to be tired so sleep is needed for the body to produce energy again. 

In addition, lack of sleep can also make your body susceptible to disease. The body and its system need time to rest to recharge after tired of doing many activities all day. However, if you don't give your body enough time to rest, it can become weak and susceptible to disease. 

Reduced skin health 

Lack of sleep can lead to less firm skin, leading to fine lines and dark circles under the eyes in many people. This happens because lack of sleep makes the body produce excessive amounts of the hormone cortisol and causes the body to break down collagen in the skin so that the collagen content in the skin decreases. This is not good for skin health. Collagen is a protein that makes skin smooth and elastic. 

How to make up for the lack of sleep?

The only way to regain your lost sleep is to get more sleep. You can make up for your lack of sleep on holidays. Try to increase your nighttime sleep by an hour or more. All you have to do is sleep when you feel tired at night, and allow your body to wake up in the morning on its own. That way, you will slowly get your normal sleep time. 

Reduce the habit of staying up late at night if there is nothing to do. In addition, try to reduce the consumption of caffeinated drinks. Caffeinated drinks may help reduce your sleepiness at night for a few hours, but the downside is that it can damage your sleep patterns in the long run.
