As spring begins, the Royal Netherlands Meteorological Institute (KNMI) expects more sunshine in the coming days. As the sun is rising higher in the sky, UV radiation levels can already reach level 3. Since skin is not yet used to the sun after the winter months, it can burn quickly. Experts advise the public to enjoy the weather while taking active steps to avoid sunburn.
Sunlight offers several health benefits. It can improve mood and encourage people to spend more time being active outdoors, which helps prevent chronic diseases. The body also produces vitamin D when exposed to sunlight, which is essential for healthy bones and muscles. However, excessive ultraviolet (UV) radiation is harmful. It causes the skin to age faster, leads to sunburn, and is the primary cause of skin cancer. It can also contribute to the development of cataracts.
From now until September, protection is necessary. The National Institute for Public Health and the Environment (RIVM) advises particular care when the UV index reaches level 3 or higher. Children require extra attention as they have more sensitive skin.
UV index and impact
| UV Index | Exposure Level | Time to Burn | Recommended Protection |
| 0-2 | Low | 60+ mins | Wear sunglasses on bright days. |
| 3-5 | Medium | 30-45 mins | Use SPF 30+, wear a hat, and seek shade midday. |
| 6-7 | High | 15-25 mins | Protection is essential. Reduce time in the sun between 10:00 and 16:00. |
| 8-10 | very high | 10 mins | Minimise outdoor time. Wear UV-blocking clothing. |
| 11+ | Extreme | 5 mins | Avoid the sun. Unprotected skin burns in minutes. |
Protective measures
Health officials recommend several protective measures. When planning activities, check the UV forecast on the KNMI website or app. It is best to stay out of the sun as much as possible between 12:00 and 15:00, when radiation is strongest. Children under two years old should be kept out of direct sunlight entirely.
Protective clothing is also highly effective. Wear items that block UV radiation, including wide-brimmed hats and UV-filtered sunglasses. For any exposed skin, apply sunscreen with at least SPF 30 and a broad-spectrum UVA filter. This should be reapplied every two hours, even when sitting in the shade.
The RIVM measures UV radiation every ten minutes to calculate the current intensity. Monitoring these levels allows the public to take the necessary precautions against skin damage and long-term health risks.
