To say that the sun is both friend and foe is no exaggeration.
Its glow gives us warmth, light and vitamin D, but it can also be a formidable adversary, especially when it comes to sunburn.
While many think they are safe underwater, the reality is quite different.
Yes, you can get sunburned in the water, and here’s why.
Sunlight: A Double Sword
The sunlight consists of a spectrum of different wavelengths, ranging from infrared to ultraviolet.
The majority of these wavelengths are beneficial to our health, promoting the production of vitamin D and helping to regulate our biological clock. However, the ultraviolet rays (UV) can have harmful effects on our skin.
There are two types of UV rays that reach the earth’s surface: UVA and UVB rays. THE UVA rays are able to penetrate deep into the skin causing long term damage such as premature aging and skin cancer. THE rayons UVBalthough less penetrating, are directly responsible for sunburn.
The effects of UV rays underwater
Contrary to popular belief, water does not completely block UV rays.
In fact, it can even amplify them. This is due to the refraction light, a phenomenon that occurs when light passes from one medium to another, in this case from air to water.
Refraction can increase skin exposure to UV rays, especially in clear, shallow waters where sunlight can easily penetrate. Additionally, reflective surfaces like water can reflect up to 10% of UV rays back to the skin, increasing the risk of sunburn.
Sun protection: a necessity even underwater
Even underwater, the use of a sunscreen is crucial.
It should be applied generously to all parts of the body exposed to the sun, including the underarms and the backs of the legs, which are often neglected.
It’s also important to choose water-resistant sunscreen and reapply it regularly, especially after swimming or sweating. In addition, it is recommended to use sunscreen with a sun protection factor (SPF) of at least 30, which blocks 97% of UVB rays.
How to calm a sunburn?
To calm a sunburn, there are several natural and simple remedies to put into practice. First, it’s important to protect yourself from the sun and avoid further exposure until the sunburn has healed.
To relieve pain and inflammation, applying cold compresses to the affected area can be effective. You can use ice cubes wrapped in a clean cloth or apply damp, cool towels.
It is also recommended to moisturize the skin abundantly using after-sun creams or lotions containing aloe vera, cucumber or chamomile gel, which have soothing and moisturizing properties.
Certain herbs can also help relieve sunburn, such as brewed green tea, which can be applied to the skin or used to take cooling baths.
Finally, it is essential to drink plenty of water to maintain good hydration and promote healing of the skin. If symptoms persist or worsen, it is recommended to consult a health professional.
It is quite possible to get a sunburn underwater. The sun’s UV rays can not only pass through the surface of the water, but can also be amplified by refraction and reflection.
Therefore, it is imperative to always use sun protection, even when in the water. By understanding the dangers and taking the necessary precautions, we can enjoy the sun while protecting our skin.
