Delhi-NCR is experiencing a severe heatwave, with temperatures expected to soar up to 45°C this week. The India Meteorological Department (IMD) has issued a yellow alert for heatwave conditions on Monday and Tuesday. The mercury rose sharply to 42.1°C at Safdarjung, Delhi’s main weather station, on Sunday—crossing the dreaded 40°C mark once again. And it’s not cooling down anytime soon. The IMD warns the heatwave will persist, affecting not just your comfort but also your health—especially your skin.
The combination of scorching heat, high humidity, and pollution is a dangerous mix for your skin. From painful sunburns and prickly heat to fungal infections and acne flare-ups, your skin faces multiple threats during this intense pre-monsoon spell—one of the hottest Delhi has seen in years. Severe heatwave alerts have also been issued in nearby cities like Noida, Gurugram, and Faridabad.
To better understand how extreme heat affects the skin and how to protect yourself, we spoke with Dr. Sheena Kapoor, Consultant Dermatologist at Kokilaben Dhirubhai Ambani Hospital, Indore.
1. Heat rash (Prickly heat or miliaria)
Heat rash happens when sweat ducts get blocked, trapping sweat under your skin. It shows up as tiny red bumps or blisters, usually on the neck, back, chest, and underarms. “Wearing light, breathable fabrics and taking cool showers can prevent heat rash,” advises Dr. Kapoor.
A 2018 study in the Indian Journal of Dermatology observed a sharp rise in sweat-induced dermatitis cases from April to June in India’s coastal regions, indicating how common this problem is during the hot months.
2. Sunburn and UV damage
With Delhi’s UV index often hitting “very high” levels, sunburn can occur in as little as 20 minutes. Symptoms include redness, burning sensation, and peeling skin. Further, UV damage can lead to premature ageing and increase skin cancer risk.
“Apply a broad-spectrum sunscreen with SPF 30 or higher, especially between 10 am and 4 pm when UV rays are strongest,” Dr. Kapoor urges. Wearing hats and sun-protective clothing is also recommended.
3. Hyperpigmentation and tanning
Constant sun exposure not only tans your skin but can also cause uneven pigmentation and dark patches. The heat itself, even without direct sun, can stimulate pigment-producing cells, worsening skin tone irregularities.
Experts suggest using antioxidant serums with vitamin C or niacinamide alongside sunscreen to combat pigmentation issues.
4. Acne breakouts
Heat, sweat, and pollution combine to clog pores and fuel acne. Heat and humidity create the perfect environment for acne-causing bacteria. Switch to gentle cleansers, avoid heavy creams, and opt for non-comedogenic skincare products during the summer months, suggests Dr Kapoor.
A 2015 study found that acne severity increases during the hot months due to increased oil production and sweat.
5. Dry skin
You might expect oily skin in the heat, but dry skin is also common—especially from air conditioning and dehydration. Flaky, tight skin can result if you don’t hydrate enough or use harsh soaps.
The American Academy of Dermatology recommends lightweight, water-based moisturizers and plenty of water intake to maintain skin hydration.
6. Eczema and redness flare-ups
If you suffer from eczema or sensitive skin, the heatwave can worsen your symptoms, causing itching, redness, and inflammation.
“Heat and sweat trigger flare-ups, so use fragrance-free skincare, avoid hot showers, and apply doctor-recommended barrier creams,” advises Dr. Kapoor.
7. Fungal and bacterial infections
Sweaty, warm skin folds are ideal breeding grounds for fungi and bacteria. Conditions like athlete’s foot, ringworm, and heat boils increase during heatwaves.
A 2022 report by the National Institute of Communicable Diseases noted a seasonal rise in fungal infections in Delhi during heat spells. “Change sweaty clothes quickly, keep skin dry, and use antifungal powders or creams if needed,” says Dr. Kapoor.
Prevention is key
To protect your skin during this brutal heatwave, Dr Kapoor recommends:
- Avoid going outdoors between 11 am and 3 pm when the sun is strongest.
- Wear loose, breathable cotton clothing.
- Apply sunscreen generously and reapply every 2-3 hours.
- Stay hydrated by drinking plenty of water.
- Wash your face and body regularly to remove sweat and pollution.
- Use gentle, non-comedogenic skincare products.
- Keep skin folds dry and change clothes if they get sweaty.
If you experience persistent or worsening skin problems, it’s best to consult a dermatologist for early treatment. This heatwave is a threat to your skin’s health. Hence by taking simple precautions, you can keep your skin safe, healthy, and glowing even in the hottest days ahead.
