Health Maintenance During Heatwaves
To minimize the impact of heatwaves and prevent heat-related illnesses, consider these measures:
- Stay Hydrated: Drink sufficient water frequently, even if you’re not thirsty. Carry water with you while traveling and consume fluids like lemon water, ORS (Oral Rehydration Solution), and juices. Avoid alcohol, tea, coffee, and carbonated soft drinks, as they can dehydrate the body.
- Appropriate Clothing: Wear lightweight, light-colored, loose, and porous cotton clothes. When going out, use protective goggles, an umbrella/hat, and shoes or sandals. Apply SPF 30+ sunscreen.
- Avoid Peak Heat: Avoid going out in the sun, especially between 12:00 noon and 3:00 p.m. Avoid strenuous activities when the outside temperature is high and avoid working outside during the hottest hours.
- Dietary Precautions: Avoid high-protein and stale food. Eat fresh, seasonal fruits, salads, curd, and water-rich foods like cucumber and watermelon. Avoid oily, spicy, and heavy meals.
- Keep Cool: Stay in cool places. Keep your home cool by using curtains, shutters, or sunshades and opening windows at night. Use fans and damp clothing, and take cold showers frequently. Check your fans and air-conditioners to make sure they are working and that filters, pads, and air vents are clean.
- Protect Yourself Outdoors: If you work outside, use a hat or an umbrella and a damp cloth on your head, neck, face, and limbs.
- Take care of your eyes: Wear sunglasses.
- Avoid strenuous activities: Cancel or reschedule activities for the coolest part of the day and avoid exercising and being outdoors in the heat.
- Additional Tips: Do not leave children or pets in parked vehicles. If you feel faint or ill, see a doctor immediately. Use homemade drinks like lassi, torani (rice water), lemon water, and buttermilk to rehydrate the body. Keep animals in the shade and give them plenty of water.
- Monitor Air Quality: If the air quality deteriorates, cover your face with a mask, limit outdoor activities, and take prescribed medications if you have pre-existing conditions like asthma or bronchitis
