The harmful effects of the sun on the skin can be noticed by observing the appearance of sunburn, spots and even the terrifying skin cancer. Moreover, exposure to sunlight always carries a greater or lesser risk. Apply sunscreen and develop healthy habits.
Do you know the harmful effects of the sun on the skin associated with excessive sun exposure?
It is true that without the sun the development of life on Earth would not be possible, and the sun’s rays have their positive sides. Thanks to their absorption, plants are able to carry out photosynthesis. In turn, for humans they are a source of vitamin D. However, in order to enjoy the full benefits of the sun, you need to carefully monitor the time in which we expose ourselves to it.
Staying in the sun is healthy only in limited amounts. After exceeding a certain limit, its rays can start to harm the skin, eyes and the health of the entire body. The harmful effects of the sun on the skin can manifest as wrinkles, dark spots, burns and premature aging of the skin. Some people may develop photoallergic reactions and even skin cancer.

The harmful effects of the sun on the skin
Virtually all of us have experienced unpleasant symptoms associated with sunburn. Perhaps it happened on a sunny day at the beach or in the mountains, when the skin was not properly protected. I don’t think anyone can forget those nights of pain and discomfort.
When sunburn does occur, the skin turns red. Occasionally it has blisters and may even become inflamed. Plus, it is hot to the touch and hurts all the time, such as when clothes rub against it. Dehydration may even occur at times, and in extreme cases, second-degree burns may occur.
The sun’s UV radiation is responsible for the burns. It triggers a defensive reaction consisting in thickening of the epidermis. Symptoms usually appear a few hours after being in the sun, and their intensity depends on several factors, mainly on the body’s ability to absorb this type of radiation.
Premature skin aging
The negative effects of solar radiation accumulate, even if you are exposed to low intensity rays. One of the most visible effects is premature skin aging associated with spending too much time in the sun. 90% of it is caused by sunlight. This harmful effect manifests itself in the form of discoloration, wrinkles and loss of firmness through the skin. This is because excessive sun exposure reduces the amount of collagen and elastin.
When in the sun, UV rays are responsible for premature skin aging. It gets to it because they penetrate your skin and reach the dermis, leading to sudden and transient melanin pigmentation that makes the skin darker.
Allergy to the sun
Allergy to the sun seems strange, especially considering the fact that it is present in our daily lives. However, this condition affects many people. It is estimated that about 20% of people worldwide suffer from them.
This type of allergy is associated with other allergic reactions, such as those caused by certain foods, chlorine in the pool, lotions, medications, and even clothes. Allergic reactions may occur when staying in the sun.
Skin cancer: worst effect of the sun
Exposure to the sun can also lead to the development of skin cancer, caused by UV rays, which damage skin cells. Several factors influence the appearance of this type of neoplasm. For example, its occurrence is associated with frequent exposure to the sun, leading to the appearance of sunburn, skin phototype, genetic factors and age.
This type of cancer is most common in the areas of the skin that are most exposed to sunlight, including the face, hands, and neck. The risk of its occurrence increases dramatically in the event of sunburn. The type of skin is also important: people with lighter skin and eyes are among the high-risk group.
Another determining factor is family history of melanoma and age. The risk of skin cancer increases in people over 40 years of age. The most common types of skin cancer are melanoma and basal cell carcinoma.
- Melanoma is a fairly aggressive and very malignant type of skin cancer.
- Basal cell carcinoma is the most common type of skin cancer that grows slowly and is easier to treat.
In conclusion, we hope you already know the harmful effects of the sun on your skin and why you should protect yourself from it. As in most cases, prevention is better than cure!
