Photosensitivity (Holistic)

Photosensitivity (Holistic)

About This Condition

A red rash that breaks out on your body during sun exposure may mean you’re “allergic” to light. According to research or other evidence, the following self-care steps may be helpful.
  • Try beta-carotene

    Increase your tolerance to sunlight by supplementing with beta-carotene

  • Shield your skin from the sun

    Steer clear of excessive sun exposure by wearing protective clothing or smoothing on sunscreen

  • Get a checkup

    Visit a qualified healthcare provider to find out if your photosensitivity is caused by a treatable medical condition or a side effect of medication

About

About This Condition

People with photosensitivity have an immunological response to light, usually sunlight. They typically break out in a rash when exposed to sunlight; how much exposure it takes to cause a reaction varies from person to person. Several conditions, such as erythropoietic protoporphyria and polymorphous light eruption, share the common symptom of hypersensitivity to light—also typically sunlight.

People taking certain prescription drugs (sulfonamides, tetracycline , and thiazide diuretics) or herbs ( St. John’s wort , for example) and those with systemic lupus erythematosus have increased susceptibility to adverse effects from sun exposure.

Symptoms

Symptoms may include a pink or red skin rash with blotchy blisters, scaly patches, or raised spots on areas directly exposed to the sun. The affected area may itch or burn, and the rash may last for several days. In some people, the reaction to sunlight gradually becomes less with subsequent exposures.

Healthy Lifestyle Tips

People with photosensitivity need to protect themselves from the sun by using sunscreen, wearing protective clothing (such as long-sleeved shirts), and avoiding excess exposure to the sun.

Eating Right

The right diet is the key to managing many diseases and to improving general quality of life. For this condition, scientific research has found benefit in the following healthy eating tips.

Recommendation Why
Avoid alcohol
One of the conditions that may trigger photosensitivity—porphyria cutanea tarda—has been linked to alcohol consumption. People with this form of porphyria should avoid alcohol.

One of the conditions that may trigger photosensitivity—porphyria cutanea tarda—has been linked to alcohol consumption.1 People with this form of porphyria should avoid alcohol. Some people have been reported to develop a photosensitivity reaction to the artificial sweetener, saccharin.2

Supplements

What Are Star Ratings?

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by some in the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.

2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.

1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Supplement Why
3 Stars
Beta-Carotene
100,000 to 300,000 IU daily under medical supervision

Caution: Synthetic beta-carotene has been linked to increased risk of lung cancer in smokers. Until more is known, smokers should avoid all beta-carotene supplements.

Years ago, researchers theorized that beta-carotene in skin might help protect against sensitivity to ultraviolet light from the sun. Large amounts of beta-carotene (up to 300,000 IU per day for at least several months) have allowed people with photosensitivity to stay out in the sun several times longer than they otherwise could tolerate.3 , 4 , 5 The protective effect appears to result from beta-carotene’s ability to protect against free-radical damage caused by sunlight.6

1 Star
Adenosine Monophosphate
Refer to label instructions
Learn More

Adenosine monophosphate (AMP) is a substance made in the body that is also distributed as a supplement, although it is not widely available. According to one report, 90% of people with porphyria cutanea tarda responded well to 160 to 200 mg of AMP per day taken for at least one month.7 Complete alleviation of photosensitivity occurred in about half of the people who took AMP.

1 Star
Fish Oil

In a small preliminary trial, supplementation with fish oil (10 grams per day for three months) reduced photosensitivity in 90% of people suffering from polymorphous light eruptions.8

1 Star
Vitamin B3
Refer to label instructions
Learn More

Niacinamide , a form of vitamin B3, can reduce the formation of a kynurenic acid—a substance that has been linked to photosensitivity. One trial studied the effects of niacinamide in people who had polymorphous light eruption.9 While taking one gram three times per day, most people remained free of problems, despite exposure to the sun. Because of the potential for adverse effects, people taking this much niacinamide should do so only under medical supervision.

1 Star
Vitamin B6
Refer to label instructions
Learn More

Cases have been reported of people with photosensitivity who responded to vitamin B6 supplementation.10 , 11 Amounts of vitamin B6 used to successfully reduce reactions to sunlight have varied considerably. Some doctors suggest a trial of 100 to 200 mg per day for three months. People wishing to take more than 200 mg of vitamin B6 per day should do so only under medical supervision.
