Dry air produced by air conditioning can lead to dehydration and dry skin and lips, according to Associate Professor, Dr. Nguyen Nhu Vinh, Head of the Department of Respiratory Function Investigation at Ho Chi Minh City University of Medicine and Pharmacy Hospital. To minimize these effects, it is important to set the right temperature in the room, keep the air conditioned space well ventilated, and regularly clean the air filter to prevent the spread of bacteria and viruses. Additionally, staying hydrated by drinking enough water throughout the day and avoiding direct exposure to cold air can help prevent dryness. Adjusting the lighting in the room can also help reduce the feeling of heat caused by air conditioning. If you are experiencing health issues related to air conditioning use, it is recommended to consult a medical professional for appropriate advice and treatment.
