What is the cause of spring sleepiness?

The problem of spring sleepiness cannot be ignored. After all, it will have a certain impact on our work, life and study. As for the cause of spring sleepiness, we should also pay attention to whether it is caused by not drinking enough water, or by eating junk food for a long time, coupled with bad living habits.

1. Not drinking enough water.

Even mild dehydration (a loss of just 2% of normal body fluids) can affect energy levels. Dehydration causes the blood to become thicker, reducing the heart's efficiency in delivering oxygen and nutrients to various tissues and organs.

2. Insufficient iron intake.

Iron deficiency can affect the flow of oxygen to muscles and cells, causing sluggishness, irritability, physical weakness and inability to concentrate.

3. Eating unhealthy breakfast.

Eating a good breakfast can stimulate metabolism and give people enough energy for the whole day. Skipping breakfast will make people feel lazy.

4. Love to eat junk food.

This can cause blood sugar levels to spike and plummet, leading to fatigue.

5. Drinking before going to bed.

Alcohol lowers blood sugar levels, depresses the central nervous system, produces a sedative effect, and ultimately disrupts sleep. This is because alcohol can cause adrenal gland secretion disorders during metabolism, making drinkers easily wake up at night.

6. Playing with mobile phone on bed.

The blue light emitted by the displays of tablets, smartphones, etc. will inhibit the secretion of melatonin, disrupt the body's natural physiological rhythm, and cause fatigue.

7. Staying up late and sleeping in.

This can make it difficult to fall asleep at night and wake up in the morning. You should also wake up at a fixed time on weekends. If you want to take a nap, don't take more than half an hour, otherwise you will be more tired when you wake up.
