A number of years in the past, I obtained a prognosis that might have made a former Goth completely happy: I’m allergic to the sun.

It’s really extra of a sensitivity kind than an allergic response (we’ll get to that in a bit), however it causes my pores and skin to interrupt out in tiny, horrible, itchy bumps each summer season.

This is known as polymorphic gentle eruption and seems as a rash that happens when the pores and skin is uncovered to daylight. Although the pores and skin can grow to be allergic to the sun for a number of causes, photodermatosis is the commonest type of photosensitivity. And he is extremely annoying.

It normally begins behind the hand after which slowly strikes up the hand. Scratching makes it worse, however it is so itchy that I get up scratching my arm in the course of the night time. Also, it’s not fairly in any respect – some fool commented on my “zombie” arms at a celebration.

First, I obtained a number of false eczema diagnoses earlier than realizing that eczema is an annual rash, which is not unusual. In reality, it impacts 15 % of all individuals, and it principally impacts youngsters and truthful-skinned girls of their 20s who stay within the north and have a household historical past of the illness.

Sun allergy symptoms: Some persons are particularly susceptible to itchy rashes

I requested the dermatologist to present me all of the details about sun allergy symptoms.

First, it is not the identical as an allergy. “I do not suppose you can name it an allergy,” says Dr. Whitney High, MD, chief of dermatopathology on the University of Colorado School of Medicine.

However, it is comprehensible why it is usually known as “sun allergy”. Allergies happen when the immune system overreacts to proteins in meals, pollen, or animal dander. Polymorphic gentle eruption, then again, is photosensitivity or the physique’s response to ultraviolet rays.

Doctors nonetheless do not know precisely what causes it, however in individuals with photodermatosis, publicity to the sun’s UV rays causes irritation, swelling, itching, and an immune response that causes a number of rashes, together with small blisters and swollen pores and skin. coating.

“Even now, when it’s really widespread, we nonetheless do not know why individuals get it,” High continued.

But the passing of time offers info. How the rash develops over time is an necessary indicator of photodermatosis, not one other pores and skin illness.

“Swelling and redness normally happen 4 to six hours after publicity to the sun,” says Hai. “The rash, redness, swelling, itching and related signs final 2-3 days. Then the immune system slowly stops reacting and the pores and skin returns to regular.”

This normally occurs in early summer season, when our pores and skin is uncovered to extra daylight. For me, the breakouts normally begin within the fall after which step by step worsen earlier than beginning to clear up once more in mid-summer season. This is very typical, as a result of the longer the pores and skin is uncovered to the sun, the much less the signs can be.

Sun allergy symptoms can’t be cured, however the signs can be handled

But dermatosis is not solely in summer season. I’m fairly certain it’ll be up and working inside 24 hours if I’m vacationing someplace heat within the winter. Not humorous.

There is no treatment, however dermatosis can be handled. Instead of ready for the rash to go away by itself, you can pressure your physique to combat the issue. Hai says he as soon as had an intern with photodermatosis polymorphosis who used UV gentle to pressure the response to hurry up. (You ought to needless to say tanning beds are suspected of inflicting pores and skin most cancers. Although UV lights are used to deal with pores and skin situations akin to psoriasis, you ought to seek the advice of your physician first about utilizing photodermatosis.)

Otherwise, topical corticosteroids are beneficial. I can inform you from my very own expertise that an anti-itch ointment is additionally a boon.

Prevention is additionally necessary, which means carrying lengthy sleeves and large hats. You suppose sunscreen is good, however it does little. It takes little or no sun to set off a response, so sunscreen has little impact, High says. All in all, the sunscreen is overrated due to these 19 cool photographs (which are not meant to be taken solely critically).

But the excellent news is that dermatosis doesn’t hurt the pores and skin in the long term. “It’s not harmful in any respect,” High confirms. “It would not trigger most cancers or an infection, and it’s not contagious.”

The worst factor about it is how it seems to be, however the good factor is that you all the time have an excuse to hold an umbrella. The danger decreases throughout menopause: some research present that dermatosis is related to the feminine hormone estrogen.
