Taking a medical history, baby P. often has sore throat and runny nose. He often stays in an air-conditioned room at school and home; at night he sleeps in an air-conditioned room around 22 degrees Celsius. For a week now, he has had the above symptoms but taking medicine has not helped.

In another case, Mr. DNT (27 years old, living in Binh Thanh District, Ho Chi Minh City) had a sore throat, hoarse voice, prolonged dry cough, and fatigue. He coughed so much and continuously that he felt pain in both sides of his ribs. Mr. T. bought medicine to drink and gargle for the past 2 weeks but it did not get better, so he went to Tam Anh General Hospital, Ho Chi Minh City for examination.

The results of the nasopharyngoscopy at the ENT Center, Tam Anh General Hospital, Ho Chi Minh City, showed that Mr. T. had a congested throat, tonsil ulcers, and swollen lymph nodes in his neck.

Similarly, MTKP (5 years old, living in Binh Thanh district) came to Tam Anh General Hospital in Ho Chi Minh City with a continuous cough, runny nose, sore throat, discomfort, fatigue... The symptoms appeared a week ago, when the child went swimming and came home and immediately went into an air-conditioned room with a temperature of 18 degrees Celsius.

After that, the more the baby lay in the air conditioner, the more he coughed and his throat hurt, but when the air conditioner was turned off, he could not stand it and cried. After the endoscopy, the doctor diagnosed baby P. with acute pharyngitis, treated him with internal medicine and returned for follow-up examination.

The habit of sleeping with your mouth open increases the risk of sore throat.

Master - Doctor CK1 Truong Tan Phat, ENT Center, Tam Anh General Hospital, Ho Chi Minh City, explained that hot weather causes high temperatures, people tend to use air conditioners continuously, all day long, keeping the room temperature around 17-20 degrees Celsius or letting cold air blow directly on the face, neck, and back of the neck. This seriously affects the respiratory system.

To prevent sore throat in hot weather, if using air conditioning, do not set the temperature below 26 degrees Celsius.

When using air conditioning, the doors are closed, cold air is a condition for bacteria to grow. The cold environment also causes the nasal and throat mucosa to dry, the body's resistance to weaken, and the body temperature to decrease. These factors are opportunities for bacteria and viruses to attack the throat mucosa. For people who are sick, with weak resistance, when attacked by bacteria and viruses, the throat mucosa will be more damaged, the disease will not go away but will last for a long time.

In particular, the habit of sleeping with your mouth open in an air-conditioned room increases the risk of sore throat. When sleeping, saliva is not enough to supply the throat, while the air conditioner dehumidifies the air, making the throat dry, sore and painful.

According to Dr. Phat, in addition to the habit of overusing air conditioners, there are other causes that cause sore throats in many people, such as drinking too many cold drinks or letting the fan blow directly on the person.

Hot weather, when using air conditioning, do not set the temperature below 26 degrees Celsius

Doctor Phat recommends that to prevent sore throat in hot weather, if using air conditioning, the temperature should not be below 26 degrees Celsius. The temperature of the air-conditioned room should be stable at around 26-28 degrees Celsius, the air conditioner should only be turned on from 11 pm to around 3-4 am the next morning. Cover yourself with a thin blanket when sleeping at night, and clean the air conditioner 2-3 times a year. Families with small children need to ensure the minimum temperature is 28 degrees Celsius.

In addition, everyone should clean their nose and throat daily with saline, drink enough water (2 liters/day), limit eating foods that are too cold, spicy, hot; limit smoking and drinking alcohol; wear a mask when leaving the house; and limit going to places with a lot of dust and smoke.
