Varanasi is experiencing an intense heatwave that has spread across parts of Uttar Pradesh. Experts are warning that without proper precautions, this extreme weather could escalate into a health crisis. Hospitals in the region are reporting an increase in heat-related cases, prompting urgent advice from medical professionals.
Body's Cooling System Disrupted by Extreme Heat
Dr Shivshakti Prasad Dwivedi, Government Medical Officer and CPR specialist, explained that extreme heat disrupts the body's natural cooling system. Normally, sweating helps regulate temperature, but severe heat combined with high humidity can stop this process. This leads to the loss of essential water and electrolytes like sodium and potassium, which can adversely affect the brain and heart.
Vulnerable Groups at Higher Risk
According to Dr Dwivedi, heatwaves pose a particular danger to children, elderly individuals, pregnant women, and those with pre-existing conditions such as diabetes, hypertension, heart disease, obesity, and kidney disorders. These groups have a lower adaptability to extreme temperatures, making them more susceptible to heat-related illnesses. Extra caution is essential for these high-risk populations.
Precautionary Measures Advised
Dr Dwivedi appealed to the public to avoid unnecessary exposure to sunlight between 11 am and 4 pm. If stepping out is unavoidable, individuals 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.
Dehydration becomes a major health concern during extreme heat. Maintaining adequate hydration is extremely important, even if one does not feel thirsty. Dr Dwivedi advised consuming natural fluids such as lemon water, buttermilk, coconut water, lassi, fresh fruit juices, and traditional drinks like shikanji. He warned against excessive consumption of sugary, caffeinated, and carbonated beverages, as they may worsen dehydration.
Recognizing Early Symptoms of Heat Illness
Early symptoms of heat-related illnesses should never be ignored. These include excessive thirst, headache, dizziness, weakness, heavy sweating or sudden absence of sweating, vomiting, restlessness, and high fever. In severe conditions such as unconsciousness, chest pain, breathing difficulty, confusion, or reduced urination, immediate hospitalization is strongly advised. Heat stroke can become life-threatening if left untreated.
