How Sleep Deprivation Affects Our Body

Sleeping properly each night is important to help recharge and reset the body. Lack of sleep can lead to many health complications.


Lack of sleep can affect your mood

It is recommended that an adult get about seven to nine hours of sleep each night. Sleep deprivation is defined as receiving less than the amount of sleep needed. Children and teens need even more sleep each night than adults. Even one night of insomnia or lack of sleep can leave you feeling tired and frustrated the next day. However, prolonged sleep deprivation can have more serious effects on the body.

Here’s what prolonged sleep deprivation does to your body:

Increase weight

A prolonged lack of sleep affects the levels of food-related hormones in the body. The two hormones, leptin (an indicator of satiety/appetite) and ghrelin (an indicator of hunger) are respectively reduced and increased. Hence, making you feel hungry faster. Also, the reduction in leptin could cause you to overeat without realizing it.

Reduce physical activity

Prolonged lack of sleep can hurt your energy levels and can make you feel tired and fatigued. This could cause you to reduce your movements and physical activities or stop exercising altogether.

Affect the immune system

Lack of adequate sleep can also hamper the abilities of your immune system. When you sleep, your immune system works to fight off any external factors that could harm your body, such as viruses and bacteria. Lack of sleep can reduce the body’s ability to make enough substances to fight off these invaders.

Negative impact on mental health

Lack of sleep can have a negative impact on our mood and cause mental disorders. Lack of adequate sleep has been proven to cause mental disorders such as paranoia, anxiety, depression, etc. In fact, long periods of insomnia can even cause hallucinations. A state in which you might hear, see, or feel things that do not actually exist.

cause heart disease

Sleep also affects the regular functioning of the heart as well as blood sugar, blood pressure, and other heart-related functions. Sufficient sleep allows the body to repair and heal all heart problems. A prolonged lack of sleep can increase your risk of contracting cardiovascular disease. A study has shown that insomniacs are more prone to strokes or heart attacks.

cause diabetes

As stated above, the body needs adequate sleep to properly perform heart-related functions. Lack of sleep can affect the body’s ability to regulate blood sugar levels in the body. This can cause the body to develop diabetes or other metabolism-related disorders.

Cause hormonal imbalances

Just like the diet-related hormones described above, all hormone-producing organs require the body to get enough rest in order to produce hormones in the correct amount. Lack of sleep can affect growth hormone production in children. Insomnia can also affect testosterone production in the body.

As stated above, it is extremely essential for us to get enough sleep on a regular basis. Lack of sleep affects our mood and makes us tired. In addition, a prolonged lack of sleep can cause irreversible damage to the body. If the lack of sleep is prolonged, we encourage you to consult a health professional. A doctor can help you figure out what’s disrupting your sleep routine. Plus, help you understand how to improve your sleep cycle.
