Why do people always want to sleep on rainy days?

1. The weather is relatively dark.

The secretion of melatonin in the human body is very closely related to sleep, when the secretion of melatonin is high, people will be more likely to enter a deep sleep state, so that it is very comfortable to sleep. The secretion of melatonin is related to light, and the secretion of melatonin will be more at night. In the afternoon, the weather is dark, which makes melatonin secretion, and people are more likely to be sleepy.

Although this is indeed not the time to sleep, the body's melatonin secretion does not care about this set, so the sleepiness comes, and it can't be stopped.

2. Low oxygen content.

Whether a person feels sleepy or not depends on the sympathetic nerves, and if the sympathetic nerves are very excited, people are naturally very energetic. How do you get the sympathetic nervous system excited? The answer is plenty of oxygen.

The reason why people feel sleepy on rainy days is because there is no way for plants to photosynthesize, and oxygen will be relatively low, so the sympathetic nerve is not excited, and people are prone to sleepiness.

3. The influence of sound.

If some people can't sleep at night, they will listen to some white noise on the Internet, which contains many types of sounds, one of which is the sound of rain, and the sound of rain is very typical of white noise. Noise is usually very restless and annoying, but white noise is different in that it soothes the nerves and makes people feel comfortable, so you can listen to it as a sleep aid. When the surrounding environment is very quiet and there is only the sound of rain, people will be in a very relaxed state, the body is relaxed, the spirit will also be relaxed, and they will naturally sleep very deeply, and the quality of sleep will be particularly high.

How can I keep myself from falling asleep on a rainy day?

Not everyone can sleep comfortably on a rainy day, and most people still have to continue to work and study, so they need to overcome the drowsiness caused by rainy days. If you want to make yourself feel more energetic on a rainy day, you have to start with some small details of yourself. For example, you can drink a cup of tea or coffee to refresh your mind.

Change the content of the work, and put some particularly boring and sleepy work tasks to the back to feel the energy time to do.

If you are particularly sleepy, you can take a proper lunch break, but don't take a lunch break for too long, don't let the rain affect your sleep, and wake up immediately when the time comes. If you haven't slept enough the night before, especially late, and you've stayed up late, you will feel very sleepy the next day, whether it's a rainy day or not, which will affect your work and study efficiency. Only by going to bed early and getting up early can you make your spirit better, otherwise it will be useless to do anything.

It's not your own reason that you get sleepy on a rainy day, it has a lot to do with the rain itself, so don't just look for the reason from yourself. If you want to stay awake on a rainy day, you can try some small methods to keep yourself productive.

The lowered temperature awakens the instinct for natural sleep.

Many people will sleep more soundly on rainy days for the following reasons: 1. When it rains, the increase of negative oxygen ions in the air will improve the functions of various systems such as nerves, cardiovascular, blood and respiration of the human body, and have the effect of sedation and hypnosis, making people more comfortable and easy to fall asleep.

2. The sound frequency of rain sound is generally located between 0 and 20 kHz, and this sound frequency presents a uniform distribution on the power spectrum, which we call "white noise.""Unlike other noises, white noise can make people feel calm, and the increase in water vapor in the air on rainy days leads to a decrease in air pressure and a decrease in oxygen content, at which time the brain is slack, the sympathetic nerve is low, and people will be sleepy. 3. In dim light, the pineal gland in the human body will also secrete melatonin, which is to make people tired. Melatonin is a hormone in the body that induces natural sleep, which overcomes sleep disorders and improves sleep quality by regulating a person's natural sleep.

When it rains, you sleep more soundly, not because the air is moist when it rains, nor because the rain infiltrates everything, but what affects people's sleep is actually the sound of raindrops falling on the ground, which scientists call "white noise".

Many bodily functions are in a state of slow relaxation when I am sleeping and resting, but hearing is working hard even when I am resting.

This allows some people, especially those who are more stressed, to hear very small noises in their ears when they are resting.

However, if it is a natural white noise such as the sound of rain on a rainy day, it will block out other noises, so although there is white noise of rain, it is still relatively soundly to sleep.

People want to sleep when it rains on a cloudy day, and there are several reasons:

1. Melatonin: On rainy days, melatonin in the human body will be secreted more than usual, which can shorten the time to fall asleep, promote sleep neurotransmitters, and make people tired.

Melatonin, an amine hormone produced by the pineal gland in mammals and humans, is named melatonin because it makes melanin-producing cells shine.

It is found in a wide range of organisms, from algae to humans, and its levels in the body vary sooner or later, with more secretion at night and less secretion during the day. On rainy days, when the sky is dark and the light time is insufficient, melatonin will be secreted correspondingly, and it is not surprising that people are sleepy.

2. Mild hypoxia: In the air on rainy days, there is more water vapor content, resulting in a decrease in air pressure and a decrease in air oxygen content. At this time, due to the lack of oxygen, the brain will automatically make protective adjustments to reduce excitability, resulting in sleepiness.

3. White noise: From the explanation of human living environment factors, the clicking sound of raindrops belongs to "white noise", which has the effect of promoting sleep. “

"White noise" is the opposite of "noise", which is noisy, harsh, and hinders people's normal rest, study and work, while white noise is evenly distributed and relatively "pleasant" sound.

Soothing, regular white noise can make a person feel calm and fall asleep easily. In fact, there are specialized white noise generators on the market that can emit sounds similar to those that cannot be picked up by a radio, and are marketed to insomniacs who are easily awakened by neurasthenia.
