What are Heatwaves?

Heatwaves are prolonged periods of excessively hot weather, often accompanied by high humidity. They can have serious health implications, especially for vulnerable populations. In April - May 2024 we are seeing lot of extreme temperatures with as high as 52.3 degrees in Delhi.

Heatwaves in India:
   - India is particularly susceptible to heatwaves due to its geographical location, climate, and population density.
   - Rising temperatures are linked to climate change, which exacerbates the frequency and intensity of heatwaves.
   - Hot days and nights have increased significantly, and projections indicate a two to four-fold rise in heatwave occurrences by 2050.
   - Average temperatures in India have already risen by about 0.7% between 1901 and 2018, partly due to climate change.
   - Heatwaves can be lethal: Official figures show that more than 22,000 people died from heatstroke between 1992 and 2015, but the actual toll is likely higher.

Preventing Heat-Related Illnesses:
   - Stay Hydrated: Drink plenty of water, even if you don't feel thirsty. Dehydration is a common risk during heatwaves.
   - Seek Shade: Avoid direct sun exposure between 12 pm and 3 pm, as this is when temperatures peak.
   - Wear Appropriate Clothing: Opt for lightweight, light-colored, loose-fitting, and breathable cotton clothes.
   - Protect Your Eyes and Skin: Use sunglasses, an umbrella, or a hat to shield yourself from the sun.
   - Limit Outdoor Activities: Avoid strenuous physical activity during extreme heat.
   - Know the Signs of Heat-Related Illnesses: Symptoms include dizziness, nausea, headache, and rapid heartbeat. Seek medical help if you experience these symptoms⁵.

Remember, taking preventive measures and staying informed about heatwave warnings can significantly reduce the impact of extreme heat on your health. Stay safe!
