Delhiites are experiencing unusal sharp rise in temperatures, with the city facing some of the hottest days of the season. On March 12, the temperature hit 34.8°C, the highest so far in 2025, and today, March 13, it’s already at 32.47°C.

The India Meteorological Department (IMD) has predicted that it could reach 36.08°C by the afternoon, signaling a potential heatwave.

The day started at 19.05°C, with low humidity at 17% and winds at 17 km/h, making it feel even hotter. The sun rose at 06:33 AM and will set at 06:28 PM, giving residents a long, hot day.

What is a Heatwave ?

A heatwave is defined as a prolonged period of excessively hot weather, which may be accompanied by high humidity, especially in oceanic climate countries. In India, a heatwave is typically characterized by temperatures that are significantly higher than the normal maximum temperature expected for that time of year. This phenomenon usually occurs during the summer months and is marked by dry and oppressive conditions that can lead to severe health and environmental impacts.

What is Heat Exhaustion and Heat Stroke?

The extreme weather can lead to serious health issues like heat exhaustion and heatstroke. While heat exhaustion may cause fatigue, weakness, and dizziness, heat stroke is more dangerous and can be life-threatening if not addressed immediately.

Heat Exhaustion: Heavy sweating, weakness, headache, nausea, and cold skin. If not treated, it can escalate to heatstroke.

Heat Stroke: High body temperature (above 104°F), hot and dry skin, rapid pulse, confusion, or unconsciousness. This is a medical emergency and requires immediate attention.

Dos and Don’ts to Prevent Heat Exhaustion:

To protect yourself and your loved ones from heat-related illnesses during this intense heatwave in Delhi, here’s a quick guide on the dos and don’ts:

Dos:

Stay Hydrated: Drink plenty of water throughout the day to stay hydrated. Avoid beverages that can cause dehydration, like alcohol and caffeine.

Limit Outdoor Activities: Avoid going outside during peak heat hours (10 AM to 4 PM). If you must go out, wear a hat, use sunscreen, and take frequent breaks in the shade.

Wear Light Clothing: Opt for loose, lightweight, and light-colored clothing to reflect the sun’s heat.

Use Fans or Air Conditioners: If you have access to them, stay in air-conditioned areas. Use fans to circulate air and keep cool.

Check on Vulnerable Individuals: Ensure that elderly family members, children, and people with pre-existing health conditions are coping well with the heat.

Apply Cool Compresses: Use cold towels or ice packs to cool down your body temperature if you begin to feel overheated.

Don’ts:

Avoid Strenuous Exercise: Do not engage in strenuous physical activity during the hottest parts of the day. If exercise is necessary, opt for early mornings or late evenings when temperatures are cooler.

Do Not Ignore Warning Signs: If you experience dizziness, nausea, or extreme fatigue, move to a cool place immediately, hydrate, and seek medical help if symptoms worsen.

Don’t Skip Meals: Eating small, frequent meals can help maintain energy levels, but avoid heavy, hot meals that can increase body temperature.

Avoid Alcohol and Caffeine: These substances can dehydrate your body, making you more vulnerable to heat-related illnesses.
