Staying Healthy In Extreme Heat: Health experts say that after staying in AC for a long time, suddenly going out in strong sunlight and hot air can be harmful for the body.

Why does one's health deteriorate after coming out of AC and going into the sun?
Why Stepping Out Of AC Into Heat Can Make You Sick: Amidst the scorching heat, AC has become a necessity. Whether at home, at the office, or traveling, most people spend hours in air-conditioned rooms. However, health experts say that suddenly stepping out into the bright sun and hot air after staying in an AC for a long time can be very taxing. This is why many people are experiencing problems like sore throat, dry cough, headache, fatigue, and dizziness these days.
Why does it affect?
According to a report by Dr. Nilesh Sonawane, consultant pulmonologist at Apollo Clinic, people often mistake these symptoms for a viral infection or a summer cold, but in many cases, they're caused by altered indoor air quality and a lack of humidity due to AC. According to the doctor, "Air conditioners reduce both heat and humidity in a room. This makes the air dry, which directly impacts the throat and respiratory system." Experts say that after sitting in an air conditioner for a long time, the moment a person steps outside, they are faced with intensely hot air and a sudden change in temperature. This change is a shock to the body, especially for those who spend hours in an air-conditioned office and then step directly into the midday sun.
What problems do we face?
According to doctors, it takes time for the body to adjust to sudden changes in temperature. During this time, problems like dehydration, headache, weakness, dizziness, and sometimes heat exhaustion can occur. For those who already have asthma, allergies, or respiratory problems, this situation can become even more problematic. Health experts advise avoiding direct sunlight immediately after leaving the AC. If possible, spend a few minutes in a place with a normal temperature so that the body can gradually adjust to the outside weather .
What things should be kept in mind?
Keeping the body hydrated is also considered extremely important. Prolonged exposure to air-conditioned air can increase dryness in both the body and skin. Many people don't even realize this, and as soon as they step outside, they begin to feel dehydrated. Doctors recommend drinking small amounts of water throughout the day. Coconut water, lemonade, buttermilk, and fresh fruit juice can help maintain electrolyte balance in the body.
Experts also recommend wearing light, loose-fitting cotton clothing during the summer. Also, use an umbrella, hat, or scarf when outdoors. Avoid drinking ice-cold water or drinks immediately after coming in from the hot sun, as this can increase throat irritation and discomfort.
