Consequences of not getting adequate sleep


1. Reduced concentration and productivity

Sleep is important for various aspects of brain function. This includes cognition, concentration, productivity and performance. When you haven’t slept enough, you are likely to experience excessive daytime sleepiness, tiredness and lethargy.

This could lead you to make mistakes at work, including causing accidents due to poor memory and lack of focus.

2. Increased risk of chronic diseases

Sleep deprivation also prompts your body to release higher levels of insulin after you eat. Insulin controls your blood sugar level. Higher insulin levels promote fat storage and increase your risk for type 2 diabetes.

Inadequate sleep also affects processes that keep your heart and blood vessels healthy, including your blood sugar, blood pressure, and inflammation levels. It also plays a vital role in your body’s ability to heal and repair the blood vessels and heart.

3. Reduced immunity

During sleep, your immune system produces protective, infection-fighting substances like cytokines which helps fight bacteria and viruses that could harm your body

4. Weight gain

Sleep affects the levels of two hormones, leptin and ghrelin, which control feelings of hunger and fullness.

Leptin tells your brain that you’ve had enough to eat. Without enough sleep, your brain reduces leptin and raises ghrelin, which is an appetite stimulant. The instability of these hormones could explain nighttime snacking or why someone may overeat later in the night.

A lack of sleep can also contribute to weight gain by making you feel too tired to exercise.

5. Lack of sex drive

In addition to a bad mood, sleep may also affect hormone your levels, which may cause changes in desire and arousal for sex. As a man, you will experience lower levels of testosterone, which results in a low sex drive.
