Protecting the skin from too much sun exposure is recommended for all people, especially those with light skin, in order to prevent skin cancer. Those who live with dermatomyositis, however, must be especially vigilant about avoiding sun exposure to the skin. Sun exposure, even for brief periods, can cause symptoms to flare. TMA members recommend the following extreme sun protection measures:
- Always wear sunscreen with SPF 50 minimum, even indoors and year round. Apply it to every inch of exposed skin.
- Repeat application of sunscreen 30 minutes before going out of doors, and reapply often.
- Apply sunscreen even to your hands, and be sure to reapply every time you wash your hands.
- Wear hat, sunglasses, gloves, long sleeves, and long pants/skirt when outside, even when driving.
- Black clothing is more protective than light colors, because it reflects UV sun rays better.
- Wear double layers or clothing that is specifically designed to be sun protective.
- Be aware of unexpected places where reflected UV rays from the sun may also affect your skin: moonlight, metallic rocks (such as mica), water, passing cars, and windows and other glass.
- Be aware that glass does let UV rays pass through, so shades and heavy curtains or special window coatings are recommended for home and office.
- Light bulbs emit UV rays, so LED lightbulbs are recommended for use everywhere.
- Avoid going outside between 11am and 4pm.
- Use laundry detergent with UV protection included.
