I stay in the air all day in the office, then why do I get cold when I sleep with the AC (ac rooms) running all night? Open your eyes in the morning and close your nose, someone sneezes continuously! The elders of the house often say that you should practice showering without AC. Otherwise, the ability to tolerate heat is completely reduced, immunity also goes to the bottom. But what is the way? In summer it becomes difficult to connect the eyelids.

Later the temperature increases. AC is no longer a luxury, but has become a necessity in the lives of common people. Even so, the middle class spends the whole year trying to get an AC before summer. And if the night’s sleep is not comfortable after the whole day’s work, is it possible to get the energy to go on the next day?

If the AC is run for a long time without cleaning the filter, then the dust comes out again with the air of the AC, spreading into the indoor air. As the windows and doors of the house are closed, these dust particles are inhaled into our noses. Which causes sneezing or other problems.

Do you enter the AC without drying the sweat of the body?
Not the opportunity to dry off the sweat when entering the office or anywhere else outside the home. But many habitually do it at home. Instead of sitting in the air of the fan to dry his body, he turned on the AC of the room directly from outside. This can cause severe lung damage. People with pre-existing conditions such as asthma, sinus problems or allergic rhinitis are at increased risk. Sudden changes in temperature increase prolonged discomfort.

But apart from these, AC absorbs moisture from the indoor air completely. As a result, the wet part of the human nose-throat-respiratory tract, which usually prevents dust-bacteria etc., also dries up a lot. As a result, sudden coughing starts. Or the nose stops suddenly.
