6 Signs of lack of sleep shown by your body

Sleep is very important to maintain body condition. After sleep, the body will usually return to its energy because during sleep, the cortex (the part of the brain that plays a role in storing memories of thoughts, language, etc.) will release itself from the senses and enter recovery mode. Adequate sleep can improve the body and mind so that the body can perform its best function.

The average sleep requirement for each person is at least 7 to 8 hours per day. However, often someone, maybe including you, sacrifices sleep time to complete work, tasks, or just play with their smartphone to surf in cyberspace. In fact, according to a study, lack of sleep can be associated with psychological distress and a greater risk of heart disease / type 2 diabetes.

Here are some signs that you are not getting enough sleep:

1. It's easy to forget

Sleep not only replenishes your energy, it also plays a role in the learning process. Lack of sleep can affect cognitive abilities, including in the process of learning, thinking and problem solving. So that lack of sleep can make it difficult for you to study effectively. Plus, not getting enough sleep can make it difficult for you to remember what you've learned.

2. Weight gain

If you are sleep deprived, your body will tend to produce more of the hormone ghrelin which plays a role in causing hunger and produces less of the hormone leptin which plays a role in causing satiety.

Plus, not getting enough sleep will keep you feeling tired. When you are tired, you don't pay attention to what you eat or the amount of food you eat. This can increase the risk of gaining weight.

Lack of sleep not only keeps you hungry, but also the desire to eat foods high in fat and carbohydrates. A study showed that someone who slept less than 6 hours per day was more at risk for obesity than those who slept more than 6 hours per day.

3. Get sick more easily

When you get enough sleep, your immune system will produce cytokines, proteins that help protect the body from infection. So, lack of sleep can worsen the immune system which has an impact on the production of these cytokines. As a result, lack of sleep can make it easier to get sick.

A study found that people who slept less than 7 hours per day were three times more likely to develop a cold or flu than those who slept more than 8 hours per day.

4. Stress, emotions, and depression

A study states that lack of sleep makes it easier for a person to experience stress and emotions become out of control. These uncontrollable emotions will often lead people to act without thinking or doing something bad without intending to do it.

Difficulty sleeping is usually the result of depression, while lack of sleep can also make it more prone to depression. These two things are interrelated.

5. The skin looks dull or blotchy

Enough sleep can make the skin perform optimal regeneration. So that lack of sleep can have an impact on the health of your skin, namely:

Increase the production of the hormone cortisol. The large amount of the hormone cortisol can break down collagen, a protein that plays a role in maintaining the softness and elasticity of your skin. As a result, your skin will wrinkle more easily and look older.
Reducing the production of growth hormone which plays a role in the growth process and increases muscle mass, skin thickness, and strengthens bones.
Disrupts hormonal balance and increases estrogen levels in the body. So that it can trigger the growth of acne on the skin.
Makes your eyes look tired and increases the risk of fine lines on the skin, skin tightness, and dark circles under your eyes or what is often called panda eyes.

6. Eye disorders

Without realizing it, a sign that you are lack of sleep is a disturbance to your eye health. Red eyes, tired eyes, eyes that are more difficult to focus on, and the potential for double vision is one of the traits of sleep deprivation.
