With rising temperatures due to heatwaves in India, health professionals are advising against the common practice of immediately entering air-conditioned rooms from the heat. This abrupt change can stress the body's thermoregulation, leading to symptoms like headaches, nasal congestion, and respiratory issues, particularly in sensitive individuals. Dr. Basavaraj S Kumbar from Aster Whitefield Hospital in Bengaluru emphasizes that sudden cooling can shock the body, disrupting its natural processes. To mitigate these effects, experts recommend allowing the body to adjust gradually by spending a few minutes in a shaded or moderately cool area before entering an AC room. Proper hydration is also essential, as dehydration can exacerbate the body's response to temperature shifts. Additionally, maintaining AC units is vital; dirty filters can worsen indoor air quality and contribute to respiratory discomfort. For optimal comfort and health, it is advised to set AC temperatures between 24-26 degrees Celsius and avoid direct airflow onto the body. By following these guidelines, individuals can enjoy the benefits of air conditioning while minimizing potential health risks associated with extreme temperature changes.
