What is the reason for fatigue and wanting to sleep?

Sleep is a key activity to ensure that the body gets enough rest. Sleep must happen every day. Once sleep is affected, the body may be affected. Therefore, it is very important to ensure sleep. Sleep is divided into normal sleep and fatigue sleep. Among them, what is the reason for fatigue and wanting to sleep? Let's take a look at the detailed explanation below.

From a medical point of view, there are four reasons for fatigue and wanting to sleep:

1. Physical fatigue: also known as sports or muscle contraction fatigue. When people are doing heavy physical labor, high-intensity exercise or competitions, their muscles are overly tense and the body consumes too much energy, and the body will feel tired. At this time, the body's organs and muscles need sufficient rest in order to restore their mental state. The symptoms of physical fatigue include general or local soreness, weakness, pain, fatigue, weakness and inability to do one's best.

2. Mental fatigue: Working at a desk for a long time and excessive mental work will cause excessive consumption of glucose and multiple amino acids in the blood, resulting in insufficient blood, oxygen and nutrition supply to the brain, and losing the balance between excitement and inhibition of brain cells, causing fatigue.

Symptoms include dizziness, vertigo, headache, memory loss, confusion, and inattention.

3. Mental and psychological fatigue: This type of fatigue is essentially mental fatigue, but it has a stronger mental factor and emotional color.

When repressed emotional conflicts cannot be vented, physical fatigue symptoms will appear, or strong and persistent mental stimulation may cause psychological distortion and perversion, thus inducing psychological fatigue.

4. Pathological fatigue: Studies have shown that viral infection can cause fatigue in the human body, which is characterized by persistent fatigue and difficulty in recovery.
