People with allergic rhinitis should not use air conditioning and the harm of using air conditioning

In the hot summer, especially in the south, people are tortured by the high temperature. The summer in the north, especially in the northeast, is relatively okay, with the maximum temperature basically not exceeding 30 degrees Celsius, while in the south the maximum temperature may reach 37 or 38 degrees Celsius. Therefore, air conditioning is a must-have in summer. However, frequent use of air conditioning will inevitably cause many harmful effects and can easily induce allergic rhinitis. Patients with allergic rhinitis are advised not to use air conditioning.

1. Air conditioning can easily cause allergic rhinitis

The cold air blown out by the air conditioner will stimulate the peripheral nerves in the nasal cavity, causing rapid contraction of the nasal mucosa and increased glandular secretions, leading to symptoms of rhinitis such as clear runny nose and sneezing. In addition, some people are allergic to dust and dust mites blown out by air conditioners. Studies have found that a large number of dust mites may be attached to uncleaned air conditioning filters. Once the air conditioner is turned on, dust will float everywhere. When the concentration of indoor mites reaches a certain level, it will induce allergic rhinitis.

2. Clinical manifestations

The typical symptoms of allergic rhinitis are mainly paroxysmal sneezing, clear watery nasal discharge, nasal congestion and nasal itching. Some are accompanied by decreased sense of smell.

1. Sneezing

There are several paroxysmal attacks a day, more than 3 each time, mostly in the morning or at night or immediately after contact with allergens.

2. Clearing nasal discharge

A large amount of clear watery nasal discharge may sometimes drip from the nostrils unconsciously.

3. Nasal congestion

Intermittent or continuous, unilateral or bilateral, with varying degrees of severity.

4. Itchy nose

Most patients experience itching in the nose, while those with hay fever may also experience itching in the eyes, ears, and throat.

3. What are the hazards of using air conditioning?

1. The temperature difference between indoor and outdoor is too large. If people go in and out frequently and the temperature fluctuates between hot and cold, it is easy to cause dysfunction of the body's balance regulation system. When you suddenly enter and exit an air-conditioned room, your sweat pores open and close suddenly, causing sweating dysfunction, reduced sweating, and waste from the body not being easily discharged. Sweating is the most important function for the human body to maintain a normal and healthy state in summer, and people cannot help but sweat in summer.

2. The air-conditioned room is well sealed. The indoor and outdoor air cannot be exchanged, and harmful microorganisms such as bacteria and viruses in the indoor air are easy to breed and multiply. The air quality is low. In the long run, it is easy to reduce the body's own immunity and make it easy to be infected by bacteria and get sick.

3. The air conditioner blows directly down, and the sudden cold air stimulates the sweat pores to suddenly contract, causing people to have headaches. Experts suggest that it is best to keep the room temperature constant at around 24°C, and the temperature difference between indoor and outdoor should not exceed 7°C. Windows should also be opened frequently to ensure indoor and outdoor air convection.

4. If there is a patient with rheumatism in the family, you will often hear that they feel joint pain due to the rapid drop in temperature before the weather changes. Therefore, they are often jokingly called "weather stations", meaning that their physical condition can generally predict the weather. When the temperature drops to 20-22 degrees or a strong cold wind blows directly on the body, the blood vessels in the skin and muscles will contract and the muscles will spasm. Many people will feel uncomfortable and even suffer from pain in deep muscles and joints.

5. Try not to stay in the air-conditioned room for a long time. Place a humidifier in the air-conditioned room to maintain the indoor humidity. Open windows frequently to allow air to circulate. Be sure to drink plenty of water to keep your throat moist. If you have symptoms of dry throat or sore throat, you can take throat lozenges. Once redness, swelling, pain, or cough occurs, seek medical attention promptly and receive standardized treatment under the guidance of a doctor. The effect of nebulizer inhalation treatment is often very obvious. Patients with a history of chronic pharyngitis should also receive appropriate intervention to reduce the occurrence of inflammation.
