People with lupus are actually photosensitive to the sun. This increases their risk of low vitamin D levels and could increase the damage done by this disease, resulting in more morbidity of people with Systemic Lupus Erythematosus (SLE).
11. Multiple Sclerosis (MS)
Current evidence has found there is an increased risk of developing MS when there is a vitamin D deficiency. There is also a higher prevalence of MS diagnoses in countries further away from the equator, where sunlight is the strongest. People with increased vitamin D levels have found fewer relapses with MS, less disability, and fewer lesions in the brain.
10. Skin Cancer
The link between the sun and skin cancer is typically not seen as a positive one. Radiation from the sun is said to be the biggest environmental risk factor for non-melanoma cancer. But some believe that you still need to get your sun exposure to be able to receive the vitamin D your body needs and at the same time protect your skin from damage. Research has shown a preventative effect of vitamin D on breast, prostate, and colon cancers.Related: 11 Unusual Places Skin Cancer Can Appear
