The sun is necessary for plant and animal life. Like plants, humans need the sun to live. The sun helps us synthesize vitamin D (essential for our bones), is fundamental in the regulation of the circadian sleep-wake rhythm and has other biological and psychological functions essential for the proper functioning of our body.

However, the sun has a double face because when ultraviolet radiation (UVR) is too high it is dangerous to health for several reasons. Skin cancer and cataracts are the main problems it causes, but they are not the only ones. For example, it has been shown that intense UVR is able to reach cells circulating in the blood, reaching their DNA and altering our immune status.

For these reasons, the World Health Organization has created a UVR measurement index that is now used worldwide, including Spain. This index can be consulted at any time here.

We will see a size from 1 to 11 or more and different colors. When the UVR index is 1-2 (green) you can sunbathe without any precautions. When it is 3 to 5 (yellow), sun exposure is allowed, although with certain precautions at midday. Between 6 and 7 (orange) the UVR is considered high and therefore it is recommended to be in the shade at midday and to use photoprotection methods such as sunglasses, topical sunscreen, clothing, hat, etc. A UVR index of 8 to 10 (red) is very high and justifies avoiding going outdoors during the central hours of the day, and the use of photoprotection measures is essential.

Before exposing ourselves to the sun, we must know what the ultraviolet radiation index is on that day in the geographical location where we are. In this way we will not make a mistake when choosing the activity we will do that day and the precautions we will take.

TUDERMA Anti-Aging and Antioxidant Capsulesare also a great help to protect the skin from the sun.They are an intensive antioxidant treatment for the skin that prevents skin aging and cell damage caused by ultraviolet radiation.

It also strengthens and softens the skin, improving its quality. It contains ingredients such as Polypodium leucotomos which has a photoprotective effect, due to its powerful antioxidant and anti-inflammatory activity.

It is especially indicated for people who are more vulnerable to the sun:

1. People with light skin and eyes
2. Children
3. Elders
4. People with a personal or family history of cancer

Although dark-skinned people have a lower risk of developing skin cancer, they are also sensitive to the harmful effects of UVR on the eyes and immune system.
