Why do you smell a fishy smell in the air when you wake up in the morning?

Nocturnal plants undergo respiration.

Absorbs oxygen and releases carbon dioxide.

It reduces the oxygen content in the air, but the freshness of the air is not determined by the oxygen content of the air alone. 1.Ozone content.

When the amount of ozone in the air is slightly higher, humans will feel that the air is fresh. (Actually, the ozone content is very low, so humans don't feel the smell of ozone itself.) Ozone is very unstable and decomposes easily when exposed to sunlight, so when there is no sunlight at night, the ozone content becomes slightly higher.

2.The smell of actinomycetes. Actinomycetes are microorganisms that live mainly in soil.

The "smell of grass and earth" we smell in the suburbs is actually the smell of actinomycetes. The smell of actinomycetes is stronger in the early morning, so we feel fresh in the morning air. 3.

The amount of moisture in the air. At night, water molecules in the air as the temperature gets lower.

The saturation limit is also lower than during the day when the sun is shining and the temperature is high, which means that the air is easily saturated with moisture at night. This results in slightly humider air at night and early in the morning than during the day. This feeling of humidity makes the air feel clean.

At the same time, the supersaturated water becomes water droplets, which, when liquefied, carry away the total suspended particulate matter in the air. So the air is cleaner at this time.

In cities, pollutants, dust, and water vapor are lowered to the ground as the surface temperature drops at night. As soon as the sun comes out, the temperature starts to rise, and pollutants, dust, and water vapor begin to rise. As a result, the concentration near the ground is very large, and there is this sour and wet taste.

When the surface temperature and air temperature are high enough, these pollutants rise higher into the air, and the concentration near the ground decreases, so gradually the smell becomes less pronounced.

Therefore, when exercising in the city in the morning, you must be optimistic about the weather, otherwise you may not inhale a large amount of pollutants.

It is likely that there are printing and dyeing companies around, and it is the smell of acetic acid!

It is normal for many people to sleep with the doors closed and the windows closed, the air is not circulated, and the smell of carbon dioxide is foul and unpleasant. It is necessary to wake up in the morning and open the windows for ventilation.

That's because men don't pay attention to hygiene, men themselves exercise a lot, some men don't wash their feet at night, don't take a bath, the smell of smelly socks plus sweat, plus the smell of perfume used by someone, this smell comes out, open the window, less air conditioning will be better. Forget to adopt!

Men don't like hygiene, and they don't like shampooing with all kinds of body odor and clothes.

Do you have a nosebleed and have you been on fire lately? Didn't stay up late. It is still necessary to follow the right schedule for your life.

The air has a slightly higher ozone content, ozone has a fishy smell, and at the same time has a refreshing effect. The air in the forest is fresh, which is because it contains a small amount of ozone.

It is possible that there is a release of chemicals because the doors and windows are closed and not ventilated at night.

If the conditions are insufficient, someone may be spoiled.

It is estimated that some reactions have occurred in the metabolic process of the human body, and some unpleasant gases have been produced, but it is not clear what they are.

Hello dear netizens:

First, let me introduce myself. I am a medical student studying clinical practice, mine can only represent personal opinions, do not have any authority, and are for reference only. However, please be assured that mine is cautious and confident as a member of the brilliantly knowing team.

If it's an environmental factor, there's no way around it, no one can help you online. If you are thinking about diseases, is it possible that your nasal mucosa is fragile and has a faint bleeding that causes something to smell bloody? It's not impossible, but you can try it with toilet paper, and if it's not for this reason, it's for environmental reasons, and I can't help it.

Know, help others, be happy yourself, and hope my answers will be helpful to you.

The weather was hot, and the debris in the water fermented.

The smell of earth may be the smell of ozone, and ozone has a fishy smell. It's pretty much the same as you said. Ozone can remove harmful substances in the air, in addition to not being able to remove dust, it can sterilize, disinfect, oxidize and decompose harmful chemicals in the air. Your purifier though.

There should be a certificate of conformity, some inspection reports or something. If so, there should be no problem.

Generally man-made negative ions.

All of them are negative oxygen ions produced by ionizing air at high pressure.

This is accompanied by the production of a small amount of ozone.

As for the negative oxygen ions you mentioned, it is very good for people, especially in rooms with air conditioning and computers.

The earthy smell you smell is the smell of ozone, ozone is highly oxidizing and can quickly kill bacteria and viruses and remove odors from the air.
