To stay safe from dehydration during hot summer months, prioritize consistent fluid intake. Water is best, but unsweetened herbal tea and diluted fruit juice also contribute. **Crucially, don’t wait until you feel thirsty**—thirst is a late sign of dehydration. Instead, sip fluids regularly throughout the day. Carry a reusable water bottle as a visual reminder. Increase your intake before, during, and after physical activity or sun exposure. For intense exercise lasting over an hour, consider an electrolyte-replenishing drink to counter salts lost through sweat. Monitor your urine color; pale yellow indicates good hydration, while dark yellow signals a need to drink more. Plan your day to avoid the peak heat between 10 a.m. and 4 p.m. When outdoors, wear light, breathable clothing and a hat. Seek shade frequently and use cooling strategies like damp cloths on your neck. Consume water-rich foods like watermelon, cucumbers, oranges, and strawberries, which can provide about 20% of your fluid needs. Conversely, limit diuretics like alcohol and caffeinated drinks, which can increase fluid loss. Recognize early signs of dehydration: dry mouth, fatigue, headache, and dizziness. If these occur, immediately move to a cool place and rehydrate. Severe symptoms—such as confusion, rapid heartbeat, or fainting—require urgent medical attention. By proactively drinking fluids, eating hydrating foods, and staying cool, you can enjoy summer safely and avoid the serious risks of dehydration.
