As temperatures climb, the risk of heat-related illnesses like heatstroke rises significantly. Heatstroke occurs when the body’s temperature regulation fails, pushing body temperature dangerously above 104°F. This condition can severely damage the brain and other vital organs, making prevention crucial. Staying hydrated is one of the most effective ways to avoid heatstroke. Water plays a vital role in regulating body temperature, eliminating toxins, and maintaining overall bodily functions. In extreme heat, your body loses fluids and electrolytes through sweat, leading to dehydration. To stay safe, drink plenty of fluids throughout the day, even without thirst.
