Sunlight and Health Issues

Sunlight Exposure and Health Benefits

• Vitamin D production occurs after 10-15 minutes of exposure to sunlight on face, arms, or back of legs. Use care when exposing your skin to sunlight.

 

 

Lack of Sunlight Exposure and Health Concerns

• Seasonal Affective Disorder (SAD)  may be effectively treated with light therapy, anti-depressant medicines, and/or counseling. Ask your doctor what is right for you.
  
  
  
• Even without exposure to sunlight, vitamin D may also be obtained from egg yolks, fatty fish, vitamin D enriched milk, vitamin enriched cereal, and calcium supplements. Some people may need extra vitamin D. Ask your doctor about your health concerns.

 

 

Sunlight Exposure and Health Concerns

• Photosensitive Medicines: Ask your pharmacist or doctor if any of your medicines cause sensitivity and if so, avoid sunlight while using these topical or oral medicines. Look out for photosensitivity in over-the-counter and prescription medications.
  
  
  
• Suntans and Sunburns: Sunburns can increase your risk of developing skin cancer later in life. Limit sun exposure between 10am and 4pm. Wear protective clothing and sunscreen of SPF 15-30 or more even on cloudy days. Some people also develop rashes and other conditions after sun exposure.
  
  
  
• Skin Cancer: Skin cancer is the most common form of cancer and may occur on face, lips, ears, neck, chest, arms, and hands. Some cancers are easily treated. Melanoma is less common but more dangerous than other types of skin cancer. Check with your doctor if you have any changes in your skin or you develop unusual markings. Early detection is important. Some skin cancers can spread.
  
  
  
• Eye Problems: Sunlight can damage your eyes. In the short term, exposure to UV rays can burn your eyes and long-term exposure increases the risk of cataracts, skin cancer around your eyes and other eye problems. Wear wide-brim hats and wraparound sunglasses with maximum UV protection (99-100% UVA and UVB). Eat fruits and vegetables.

What is sunburn?

What is Seasonal Affective Disorder (SAD)?

• SAD is symptoms of depression in fall and winter when there is less available sunlight and less exposure

 

What is suntan?

• A suntan is a type of skin damage where skin produces more melanin as a result of UV exposure
