Does Sunlight Exposure Help Eczema?


Eczema is a common, chronic, inflammatory skin condition that makes your skin very sensitive, inflamed, and more susceptible to the UV (ultraviolet radiation) damage. But, since eczema may make your skin more susceptible to the UV damage doesn’t mean that you should avoid going out in the sunlight. On the contrary, the exposure of your skin to the sunlight is beneficial for your skin when you happen to suffer from eczema. And, if you are wondering how sunlight exposure can be helpful to obtain relief from eczema, think no further. Read on to learn all about it.

Causes Of Eczema:

Even though the causes of eczema are quite complex, the following two factors are generally responsible for it.

  1. Altered or disturbed immunity
  2. Deficiencies in an individual’s skin barrier

Itching, skin inflammation, and redness on the skin are some of the common symptoms of eczema. Most of the time symptoms of psoriasis are same as eczema. But in case of eczema, in addition to the itchy, red, and inflamed skin, people with eczema are also more likely to develop skin infections, particularly with the bacteria Staphylococcus aureus. And, the colonization of these bacteria on the skin of the individuals with eczema (particularly, when the bacteria tend to thrive on the skin but fail to invade it), makes the condition worse by giving rise to a vicious cycle of inflamed, itchy skin which turns infected and turns more inflamed. This is why doctors focus not only on treating a person’s inflamed, irritated skin in atopic dermatitis, but also on preventing and treating the skin infection.

Fortunately, one type of treatment which may help combat both the skin inflammation as well as the infection is judicious exposure to the sunlight.

Benefits Of Sunlight:

Even though it is not completely clear why the exposure to the sun help you obtain relief from eczema, but certain medical studies suggest that vitamin D may play a vital role as the sun exposures increase the production of vitamin D in the skin. More specifically, the supplementation with oral vitamin D appears to increase the production of cathelicidin in the skin of people with eczema.

Cathelicidin is a protein which safeguards you against the skin infections, which tend to occur due to viruses, fungi, and bacteria affecting a healthy skin. And, individuals with eczema tend to have low amounts of cathelicidin present in their skin. Cathelicidin plays a critical role in mammalian innate immune defence against invasive bacterial infection. Lower levels of cathelicidin may result in colonization and infection of the skin with bacteria, viruses, and fungi, which is known to worsen eczema.

The increased production of cathelicidin may explain why people with eczema often get better with moderate amounts of sun exposure. Vitamin D supplementation to eczema affected individuals may further help enhance the effect, particularly if you are nutritionally deficient.

Cautious amount of exposure to the natural sunlight can be quite healthy, but too much sun exposure must be avoided, as people with eczema may be more prone to sunburn, particularly when they are using topical steroids.

Diagnosing Vitamin D Deficiency

The most accurate way to measure vitamin D is with the 25-hydroxy vitamin D blood test.

Natural Treatment For Eczema:

Here are some tips which can help you treat eczema naturally.

  • Have sufficient exposure to the sunlight. Going for a brisk walk in the morning can help you receive good exposure to the sunlight. The first sunrays in the morning are not quite intense so there is no risk of sunburn due to it. So, exposure to the sun in the initial phase of the morning is quite healthy.
  • Bathe less frequently with lukewarm water i.e. two or three times a week.
  • Apply moisturizer immediately after bathing or swimming.
  • Choose to use non-irritating soaps and shampoos
  • Soaking the lesion in sodium bicarbonate or colloidal oatmeal to the bath helps in reducing itching.
  • By wearing gloves in the winter, the patient can prevent skin from being exposed to the cold air with a little humidity which can dry the skin.
  • Regularly clip nails to prevent abrasion of skin while scratching. This reduces the chances of developing a secondary infection.
  • Avoid contact with allergens or irritants to the skin.
  • Kids should be encouraged to drink a lot of water daily. A good intake of fluids helps moisturize the skin naturally.
  • Food substances that provoke allergies (allergens) should be avoided.
  • Wear non-irritating cloths
  • Avoid strenuous exercises during a flare-up, as sweating can irritate the rash.
  • Minimize stress.
