Perhaps one in every ten people will experience symptoms of an allergic reaction to sunlight. These symptoms generally appear within a few hours of exposure to sunlight and include swelling of the skin that may appear anywhere on the body and is not limited to the facial area. Blistering of the skin is another common symptom of an allergy to sunlight, which may appear similar to the blistering experienced with sun poisoning, but can also occur without the extreme burn to the skin. Itching and hives are also common symptoms of an allergy to sunlight. Different from a sun burn, this extreme reaction to sunlight is believed to be the result of exposure to the ultra violet rays from the sun.
The appearance of skin affected by rosacea can also vary widely,depending on a number of factors that may influence your condition such as medications you are presently taking, sunlight, dehydration, stress, reactions to foods or beverages, and physical activity. The primary symptoms of rosacea include skin redness in the form of flushing or patchy red splotches on the face or neck, small red bumps, itching dryness of the skin or a sensation of tightness in the skin. Rosacea may be aggravated by sunlight but with rosacea the effect would be limited to the facial and neck area.
Other factors can also affect how the skin reacts to sunlight. Many prescription medications such as antibiotics can cause the skin to be more sensitive to sunlight.Even diet sodas can make the skin more sensitive to the effects of sunlight.
Some sun exposure is needed for good health. Our bodies absorb vitamin D from exposure to sunlight. This can often be achieved with 10 to 15 minutes of direct or indirect exposure to sun light a couple times a week.
Treatment for a sun allergy reaction most often will vary depending on how severe the reaction is. Quite often simply avoiding sun exposure, hydrating the body well with water and soothing the skin with twice daily applications of jojoba oil will be adequate to calm the reaction. In more extreme cases, it may be advisable to consult your primary care physician.
