Summers are becoming increasingly hot each year. With global temperatures continuously breaking records, severe heat is no longer only uncomfortable; it poses a major health risk. Heatwaves are becoming more common and powerful as a result of climate change, putting people throughout the world at risk of heat-related diseases, particularly in metropolitan areas with inadequate ventilation or limited green space.
In this blog, we’ll look at the health risks associated with rising temperatures, who is most vulnerable, and what precautions you can take to protect yourself and your loved ones over the summer.
How Rising Temperatures Affect Health
High temperatures don’t just cause discomfort—they can put real strain on the body, especially if exposure is prolonged or if there’s no access to proper cooling. Here are some of the most common heat-related health issues:
1. Heat Exhaustion
- Symptoms: Heavy sweating, weakness, dizziness, nausea, headache
- Cause: Loss of fluids and salt due to excessive sweating
2. Heatstroke (Heatstroke is a Medical Emergency)
- Symptoms: High body temperature (above 104°F or 40°C), confusion, unconsciousness, rapid pulse
- Cause: The body can no longer regulate its temperature
3. Dehydration
- Symptoms: Dry mouth, fatigue, dark-colored urine, muscle cramps
- Cause: Insufficient fluid intake during high heat
4. Respiratory Problems
- High temperatures can worsen air pollution and pollen levels, aggravating asthma, bronchitis, and other respiratory conditions.
5. Sunburn and Skin Damage
- Overexposure to UV rays can cause sunburn and increase the risk of skin cancer over time.
Who Is Most at Risk?
While heat can affect anyone, certain groups are especially vulnerable:
- Elderly people (65+)
- Infants and young children
- People with chronic illnesses (heart disease, diabetes, respiratory problems)
- Outdoor workers (construction, agriculture, delivery)
- People without access to cooling or hydration (e.g., homeless populations)
- Athletes or fitness enthusiasts training in the sun
Essential Measures to Beat the Heat
1. Stay Hydrated
- Drink plenty of water, even if you’re not thirsty.
- Avoid caffeine and alcohol—they can dehydrate you.
- Include electrolytes during prolonged outdoor activity.
2. Wear Light and Loose Clothing
- Choose light-colored, breathable fabrics like cotton or linen.
- Wear wide-brimmed hats and UV-blocking sunglasses.
3. Stay Indoors During Peak Heat
- Avoid going out between 11 a.m. and 4 p.m., when the sun is strongest.
- Use fans or air conditioning where possible.
- If you don’t have AC, spend time in public libraries, malls, or community centers.
4. Apply Sunscreen Regularly
- Use SPF 30 or higher.
- Reapply every 2 hours, especially if sweating or swimming.
5. Create a Cool Environment
- Keep curtains or blinds closed during the day.
- Use wet cloths, cool showers, and DIY ice packs for quick relief.
- Avoid heavy meals and cooking during the hottest parts of the day.
6. Know the Warning Signs
- Learn to recognize symptoms of heat exhaustion and heatstroke.
- Seek immediate medical attention if someone is confused, fainting, or has a high body temperature.
Community and Long-Term Solutions
While individual action is important, community-level efforts can reduce risks too:
- Plant more trees and create shaded public spaces.
- Install cool roofs and reflective building materials.
- Increase access to clean water and emergency cooling shelters.
- Raise awareness through public health campaigns.
Rising temperatures are no longer a distant climate issue—they’re a daily reality affecting our health. As summers become more extreme, being informed and prepared is essential.
Simple steps like staying hydrated, wearing the right clothes, and avoiding peak sun hours can literally save lives. So, take precautions, check on your neighbors, and support initiatives that cool our communities down.
