As India enters a scorching summer, temperatures are expected to surpass 40°C in some regions. Dr. Vimal Pahuja, an Internal Medicine specialist at Dr. Hiranandani Hospital in Mumbai, emphasizes the importance of hydration and diet in combating heat. While water remains the best coolant, it may not be enough during extreme heat. Oral rehydration drinks, buttermilk, and tender coconut water are recommended to replenish lost electrolytes. Cooling foods such as watermelons, cucumbers, and whole grains can help maintain energy levels without straining the metabolism. Conversely, caffeine and alcohol should be avoided due to their diuretic effects. Individuals with conditions like diabetes or heart issues are particularly vulnerable to heat stress, making it essential to adopt healthy eating habits and stay hydrated. By making informed dietary choices, people can effectively mitigate the effects of the heatwave and safeguard their health this summer.
