Why do I feel sleepy all day?

If you always feel sleepy and have no energy every day, it may be because in spring, the temperature rises and the pores of the human body open, so the blood supply increases and the brain has less oxygen, so you feel sleepy. This is what we call spring sleepiness. Some white-collar workers sit for a long time, which causes the brain to be deprived of oxygen and feel sleepy. It may also be due to psychological sleepiness.

Cause 1: Internal heat in winter

Spring sleepiness is not just a temporary physiological phenomenon caused by natural climate and rising temperature.

External factors: In the cold winter and early spring, due to the influence of low temperature, the sweat glands of the skin contract to reduce the dissipation of heat in the body. As the temperature gradually rises, the pores of the skin expand, the blood supply increases, and the oxygen supply to the brain decreases accordingly, affecting the brain's function and making the biological clock less accurate.

In winter, due to insufficient ultraviolet rays and sunlight, the body lacks sufficient vitamin D, which greatly reduces the body's immunity and working ability. When spring arrives, most of the body's functions are in a semi-dormant state.

Internal causes: It is also because of the "hot" diet in winter: spicy, fried and grilled foods, dog meat, mutton, alcohol, hot pot, etc., which can easily cause stomach fire to rise, resulting in swollen eyes and face. In severe cases, it may also be accompanied by flushed face and even rising heart fire.

Internal heat can affect a person's mental state and work mood, causing problems such as fatigue, drowsiness, insomnia, dizziness, and lack of concentration at work, directly leading to the occurrence of "spring sleepiness" syndrome. Many homes or office buildings use air conditioning in a closed environment, causing excessive levels of harmful gases such as carbon dioxide in the air, which will also aggravate the symptoms of "spring sleepiness."

Cause 2: Brain hypoxia

People who do mental work, such as office white-collar workers, are also easily "harassed" by spring sleepiness, which requires special attention.

External factors: We have just come out of winter, and many offices still have some fixed mindsets, such as not daring to open windows wide and not turning on ventilation equipment. This leads to poor air circulation, increased carbon dioxide, and extreme brain hypoxia. This is one of the reasons.

Internal factors: mainly lifestyle problems. If you sit in a chair for a long time with your legs hanging down, the blood will not get the venous pressure and will often stagnate in the feet, which will cause cerebral ischemia. Once you sit for a long time, your blood circulation function will be weakened, and you will feel tired all over. Sleepiness will come to you unknowingly, and your mind will be like a mess of paste, and you will not be able to improve your work efficiency at all.

Cause 3: Narcolepsy

When the human body gradually adapts to the rising temperature, spring sleepiness will basically no longer occur, which is why it is called "spring sleepiness". But how long will it take to get rid of the lingering spring sleepiness?

External factors: Experts believe that the length of time it takes to adapt to the temperature is related to a person's physique. People with better physical constitutions will be able to adapt in just a few days, so for them, the spring sleepiness will only last for a few days. Some people don't even experience spring sleepiness because their physical condition and blood vessels are in good condition, and they can easily adapt to weather changes in a very short time.

Internal causes: Psychological problems also cause spring sleepiness. Some people experience spring sleepiness to a very special degree. For example, some teenagers may fall asleep in any situation during the day, such as walking, eating, riding a bike, in a meeting, or even while exercising. This short sleep may last for 5 to 10 minutes, after which the person will be more awake. But you have to be careful if it occurs several times a day. Because this condition may be suffering from "narcolepsy", which is not as simple as spring sleepiness. "Narcolepsy" is common among teenagers, and its onset is uncontrollable and requires psychological treatment to resolve.
