Varanasi: With an intense heatwave hitting Varanasi and parts of UP, experts warn that it could become a health crisis if precautions aren’t taken.As hospitals in the region are witnessing a rise in heat-related cases, Dr Shivshakti Prasad Dwivedi, Government Medical Officer & CPR specialist, said extreme heat disrupts the body’s cooling system. “Sweating usually regulates temperature, but severe heat and humidity stop that, causing loss of water and electrolytes like sodium and potassium — affecting the brain and heart,” he said.According to Dr Dwivedi, heatwaves can be particularly dangerous for children, elderly individuals, pregnant women, and patients suffering from diabetes, hypertension, heart disease, obesity, and kidney disorders. These individuals have comparatively lower adaptability to extreme temperatures, making them more vulnerable to heat-related illnesses. Therefore, extra caution is essential for these high-risk groups.He appealed to the public to avoid unnecessary exposure to sunlight between 11 am and 4 pm. If stepping out is unavoidable, people should cover their heads with caps, scarves, or cloth and protect their faces and hands as much as possible. Wearing loose-fitting, light-colored cotton clothes is highly beneficial in preventing heat-related complications.During extreme heat, dehydration becomes one of the biggest health concerns. Therefore, maintaining adequate hydration is extremely important, even if one does not feel thirsty. Dr Dwivedi advised people to consume natural fluids such as lemon water, buttermilk, coconut water, lassi, fresh fruit juices, and traditional drinks like shikanji. He also warned against excessive consumption of sugary, caffeinated, and carbonated beverages, as they may worsen dehydration.He further emphasized that early symptoms of heat-related illnesses should never be ignored. Excessive thirst, headache, dizziness, weakness, heavy sweating or sudden absence of sweating, vomiting, restlessness, and high fever may be early signs of heat stroke. In severe conditions such as unconsciousness, chest pain, breathing difficulty, confusion, or reduced urination, immediate hospitalization is strongly advised, as heat stroke can become life-threatening if left untreated.
