Advantages of Ultraviolet Radiation from the Sun
Sunlight, a natural source of energy and vitamins, plays a significant role in our health. Here's a breakdown of the benefits, risks, and recommendations for sun exposure.
Anxiety-related disorders and panic attacks have been linked with changing seasons and reduced sunlight. On the other hand, exposure to sunlight can potentially help those with major depression with seasonal pattern, a condition where symptoms worsen during winter months.
The sun's ultraviolet-B radiation triggers the skin to produce vitamin D3, crucial for bone health. A 30-minute period of sunlight, while wearing a swimsuit, can help the body generate this vital nutrient. However, wearing sunscreen or layers of clothing will not allow your skin to produce vitamin D3.
For shorter periods, anywhere from 5 to 15 minutes of sunlight on arms, hands, and face 2-3 times a week is usually enough to enjoy the vitamin D3-boosting benefits of the sun. But if you're going to be outside for more than 15 minutes, it's a good idea to protect your skin with sunscreen (SPF 15 or higher), a protective hat, and shirt. Sunscreen with an SPF of at least 30 is recommended for extended sun exposure.
Sunburn is more likely to occur when the sun's rays are more direct, usually between 10 a.m. and 4 p.m. Excess sun exposure is linked with increased skin cancer risk. People with lighter skin tones typically get a sunburn more quickly than those with darker skin tones.
Beyond vitamin D3 production, sunlight may also have preventive effects on certain types of cancer, including colon cancer, Hodgkin's lymphoma, ovarian cancer, pancreatic cancer, and prostate cancer. People living in regions with higher sun exposure could expect an improved immune response against these cancers, as higher sunlight increases vitamin D3 synthesis, which supports immune system regulation and cell growth control related to cancer prevention.
Healthcare professionals have also recommended exposure to ultraviolet (UV) radiation for conditions such as psoriasis, eczema, jaundice, and acne. For those living in regions with little sunlight, a light box may provide some of the mood-boosting benefits of sunlight.
However, it's important to note that decreased sun exposure can lead to low serotonin levels, associated with a higher risk of major depression with seasonal pattern. Light therapy, also known as phototherapy, is a treatment for this condition.
Lastly, it's worth mentioning that people with rheumatoid arthritis (RA), systemic lupus erythematosus, inflammatory bowel disease, and thyroiditis may potentially benefit from sunlight, according to preliminary data.
In conclusion, while sunlight offers numerous health benefits, it's essential to balance exposure to reap these benefits without increasing the risk of skin cancer. Always remember to protect your skin when spending extended periods in the sun, and consult with a healthcare professional for personalised advice.
