In high-temperature environments, excessive sweating can reduce appetite and lead to digestive disorders. Prolonged exposure to strong sunlight may cause photodermatitis. How should one travel during hot weather?
Experts recommend the following precautions for outdoor activities in extreme heat:
1. Avoid traveling during peak hours around noon, minimizing outdoor activities between 10 a.m. and 3 p.m.;
2. Conduct outdoor activities in shaded areas whenever possible;
3. Wear breathable, heat-dissipating cotton clothing;
4. Reduce physical exertion;
5. Carry hydrating beverages; those sweating profusely may replenish fluids with diluted saltwater in small, frequent doses;
6. Enhance ventilation and utilize air conditioning where available to lower indoor temperatures;
7. Ensure adequate sleep and consume nutrient-rich fruits and vegetables;
8. Pay special attention to vulnerable groups, particularly the elderly and children, as extreme heat may trigger cardiovascular issues in seniors and adverse symptoms in children;
9. Avoid immediate cold showers when drenched in sweat; rest until perspiration dries before bathing;
10.Prevent sunburn and photodermatitis after sun exposure. If skin shows redness or swelling, rinse with cool water; seek medical attention for severe cases. If experiencing dizziness, nausea, dry mouth, confusion, chest tightness, or shortness of breath, suspect early heatstroke symptoms. Rest immediately, drink cool water to lower body temperature, and seek urgent medical care if severe.
Eating outdoors in hot weather poses risks: food is prone to microbial contamination under high temperatures. Combined with increased water intake, which dilutes stomach acid, this weakens the body's first natural defense barrier. Bacteria can enter the intestines, where bile's alkaline nature reduces its sterilizing power, increasing susceptibility to food poisoning and foodborne illnesses. Here are key reminders:
1. Thoroughly cook seafood.While summer seafood is temptingly fresh, avoid blindly prioritizing "freshness." Always ensure seafood is thoroughly cooked, stir-fried, or deep-fried before consumption. Minimize raw seafood intake. Aquatic products like hairy clams, snails, soft-shelled turtles, and bullfrogs harbor pathogens in their body cavities. Inadequate heating can cause illness.
2. Avoid wild mushrooms; ensure green beans and soy milk are thoroughly cooked. Refrain from consuming toxic or harmful foods such as wild mushrooms, fresh daylilies, or ingredients and seasonings of unknown origin. When preparing green beans or raw soy milk, ensure they are thoroughly cooked to prevent poisoning.
3. Consume cold treats in moderation.During hot summer days, people—especially children—often crave cold treats like popsicles and ice cream. While delicious, excessive consumption dilutes stomach acid, disrupts normal gut flora, weakens local immunity, and creates conditions for pathogenic bacteria to invade, increasing the risk of diarrhea.
