The beneficial effects of sun exposure are various, starting with the fact that it provides our body with vitamin D, without which we can come to bone diseases. But, at the same time, Sun can cause burns, wrinkles and can lead to skin cancer.

Besides vitamin D producing and syntheses, the Sun also prevents or helps curing some serious conditions such as: breast, prostate and colorectal cancer and multiple sclerosis.

When exposed to gentle sun rays the body is also protected against diabetes, ovary, bladder, womb and stomach cancer.

The sun releases post menstrual syndrome, or pains women encounter when they come to the monthly period.

It is interesting to notice that "the most fearful enemy" of skin - as it is considered to be the most common cause of skin cancer - can protect us from getting affected by skin cancer, psoriasis and skin tuberculosis when we expose regularly and progressively. On the contrary, we can develop melanoma when taking sudden sunbathes without preparing the skin previously.

Sun has also multiple beneficial effects on mood or affective disorders, such as stress, depression or anxiety and their symptoms: fatigue, insomnia, restlessness etc.

However, this does not mean that random exposure to the sun is allowed and risk-free, thereby a moderate exposure, especially in the morning and evening is recommended.

Most skin cancer is produced by UV (ultraviolet) rays that can cause two types of cancer: malignant melanoma, that most usually lead to death, and non-melanoma skin cancer, which is not that dangerous for our lives, but it is nevertheless slow-growing within our epidermis. The most likely to get skin cancer are the fair-skinned people that also get burned when over-exposing to the sun.

Melanoma is a cancerous (malignant) tumor which is produced by the cells in the skin that give its pigment, cells called melanocytes. Melanoma begins as a dark skin lesion and may spread rapidly to other areas on the skin and within the body.

The World Health Organization (WHO) also warns on their official web page against other diseases that may be caused by inadequate over-exposure to the sun.

The negative effects may be harmful to our eyes and vision, leading to: photokeratitis (inflammation of the cornea), photoconjunctivitis (inflammation of the conjunctiva), pterygium (growth of the conjunctiva on the surface of the eye), cataracts (the main cause for blindness) etc.

Excess sunbathing may also lead to weakening our immune system and other disorders of the skin besides cancer: lupus vulgaris (tuberculosis of the skin), psoriasis or vitiligo (a discontinuous depigmentation of the skin.)

Answer 2

The sun provides heat and light that are essential for life on Earth. It enables plants to photosynthesize and produce oxygen, which is crucial for all living organisms. Additionally, sunlight helps regulate our circadian rhythms and is a natural source of Vitamin D.
