Exercise with caution
It is advised to drink water before, during, and after physical activity if you're going to be trekking or playing a sport in the heat. Water is the best beverage for activities that last less than an hour. After an hour, replenishing lost glucose and electrolytes can be done by consuming drinks that include both sodium and carbohydrates.
Make sure to take regular breaks and have cooling supplies like ice cloths on hand. Additionally, avoid the sun between 10 a.m. to 4 p.m. and restrict your exposure. Apply sunscreen again and dress appropriately with a hat, sunglasses, and suitable clothes if you must be outside during those hours to avoid sun exposure.
