On the afternoon of March 27, the ultraviolet (UV) index in Singapore surged to extreme levels, prompting the National Environment Agency (NEA) to issue a call for heightened sun protection measures.
The UV index serves as a gauge of solar UV radiation reaching the Earth's surface, with a maximum reading of 15. NEA's website underscores that higher readings correlate with increased risks of skin and eye damage.
Health experts emphasized the rapid onset of sunburn at a UV level of 12, suggesting individuals could be susceptible within just 12 minutes of exposure. He warned of the long-term risks associated with UV radiation, including cancer and eye ailments, particularly for fair-skinned individuals.

To mitigate risks, NEA advocates for preventative measures such as using umbrellas, wearing hats and sunglasses, and applying sunscreen with a minimum SPF of 30 every two hours. The agency noted that UV levels typically peak between 11am and 3pm on clear days, with February, March, April, and September witnessing the highest UV radiation.
Measurements from the Changi Meteorological Station, reported hourly from 7am to 7pm, provide insights into UV levels, which fluctuate based on factors such as time of day, season, latitude, cloud cover, and ozone levels.

The NEA advises the public to adopt various protective measures, including wearing sunscreen with at least SPF 30, using umbrellas, wearing hats, and sunglasses, especially during peak UV hours between 11 am and 3 pm. Regular reapplication of sunscreen every two hours is essential for sustained protection.
As Singaporeans navigate the outdoors, especially during peak UV hours, adherence to sun protection measures will be paramount to safeguarding against the harmful effects of excessive UV exposure.
