What are the benefits of opening windows for ventilation?

There are many benefits to indoor ventilation, and it can also play a good preventive role in some diseases. Therefore, you should develop the habit of opening windows frequently in normal times. When you go out to work or come back in the morning, you should ventilate more. It usually takes about half an hour, and then close it. Sometimes you can also adjust the size of the opening appropriately according to the temperature. The main purpose is to allow fresh air inside. Here are some of the benefits of opening windows for ventilation.

First, ventilation can increase oxygen

If the air contains a lot of carbon dioxide, it is very bad, especially when the concentration is high, it will have a great impact on health. Generally, if the content exceeds 2%, you will feel headache, high blood pressure, etc.; when the content reaches 10%, you will lose consciousness and even die.

Second, keep the air fresh

If ventilation is not carried out for a long time, we will find that there will be a strange smell. This situation is very bad, as it can easily cause people to suffer from hypoxia. If middle-aged and elderly people stay in such an environment for a long time, they are likely to experience dizziness, nausea, palpitations, fatigue, etc. At this time, fresh air is especially needed.

Third, sterilization and dust removal

Doing this can expel some viruses, bacteria, etc., and allow the sunlight to kill some harmful substances inside, or speed up the rate at which these harmful substances fall to the ground, which can greatly reduce the amount of absorption by us. This can reduce some respiratory diseases. This is a relatively simple, effective and economical disinfection method.

What is described above is the benefit of opening windows for ventilation. I believe everyone has already understood it. I would also like to tell you that you should open windows for ventilation once in the morning and afternoon every day, each time for no less than half an hour. 9-11 a.m. and 2-4 p.m. are the best times to open windows for ventilation, because the air quality is best during these two time periods. In addition, you must keep clean when you go out.
