Sunscreen Use Gains Urgency Amid High UV Index (Image: Internet)
New Delhi: Stepping out into the sun has always required caution, but recent data suggests the risks are intensifying. In several Indian cities, including Bengaluru, the ultraviolet (UV) index has surged to extreme levels, crossing the threshold considered harmful for unprotected skin.
The UV index is an international standard measurement of the sun’s ultraviolet radiation at a particular place and time. A reading above 11 is classified as “extreme,” where even brief exposure can lead to skin damage. Reports of the index touching 13 in parts of India signal conditions where protective measures are strongly advised.

Experts attribute the spike in UV radiation to a combination of seasonal changes, atmospheric conditions, and reduced cloud cover. Urban lifestyles also contribute to increased exposure, as people spend more time commuting or outdoors during peak sunlight hours, often without adequate protection.
While sunburn is the most immediate effect, dermatologists warn of longer-term consequences such as premature ageing, pigmentation, and increased risk of skin cancer. Prolonged UV exposure can also weaken the skin’s natural barrier, making it more vulnerable to environmental damage.
Health professionals now stress that sunscreen should be part of everyday skincare, regardless of weather conditions. Even on cloudy days, up to 80 percent of UV rays can penetrate the skin. Broad-spectrum sunscreens with SPF 30 or higher are widely recommended for effective protection.

In addition to sunscreen, experts suggest wearing protective clothing, sunglasses, and seeking shade during peak hours between 10 am and 4 pm. Regular reapplication of sunscreen, especially after sweating or washing, is also crucial for sustained protection.
Despite growing awareness, sunscreen use in India remains inconsistent, often limited to vacations or outdoor activities. However, with UV levels climbing, dermatologists believe a shift in mindset is essential. Treating sunscreen as a daily necessity rather than a cosmetic add-on could significantly reduce long-term health risks.
