Jakarta: UV rays can cause sunburn, even when the sky looks cloudy. The harm to the skin also varies. However, you can take preventive measures before a bad condition occurs to your skin.
Anyone who spends time outdoors should be careful. Here are things you can do as a prevention, quoted from Medical News Today.
1. Wear sunscreen, even in the shade, on sunny days
2. Use a broad spectrum sunscreen that has a sun protection factor (SPF) of at least 30
3. Avoid sun exposure from 10:00 to 16:00.
4. Wearing tightly woven cloth
5. Wear UV blocking sunglasses
6. Wear a wide brimmed hat
7. Seek shade, if possible

Meanwhile, the UV index provides an idea of how safe you are to be outdoors at all times. At night, the index is 0, but at midday it can go up to 12 or higher.
However, these figures are not evenly distributed across regions. So, check the UV index when you are anywhere and at any time, to adjust the protection of your skin.
On the other hand, covering the sun can help, but the degree of protection depends on the clothing. For example, a plain white shirt offers an SPF of around 7, but drops to 3 if the shirt is wet.
The opacity of the fabric is also important. As the American Cancer Society says, “If you can see light through a cloth, UV light can also penetrate.”
