A little light treatment for psoriasis

It feels as if this winter has been neverending, with seemingly endless days of cold grey skiesSunflower and rain. I read a newspaper report yesterday telling us that spring is actually a whole month later arriving this year, compared to last year. Sometimes, I fear that we’ll never see the sun again, but at least this weekend’s lovely weather at last gave me some cause for hope that it’s still out there!

For sufferers of psoriasis in particular, this unseasonably poor weather is not great news. A lack of real sunlight during the winter months can manifest itself in the general population as Seasonal Affective Disorder (SAD); so for some psoriasis sufferers, this can be a double blow, as surveys have shown that over 50% of people affected by the condition have suffered from depression to a greater or lesser degree at some time. If this sounds like you, then you really do have my deepest sympathy, as coping with psoriasis can be difficult even when your mood has not been affected.

So in the absence of natural sunlight (or the possibility of flying off to somewhere sunny for a short break), phototherapy or light therapy is a treatment that has been shown to be beneficial. Ultraviolet UVA and UVB light is used to penetrate the upper layers of skin, which helps slow down the growth of new skin, which is believed to be one of causes of psoriasis. This is normally done under a doctor’s supervision, or you can buy your own light box for home treatment – although it is recommended that you continue under medical supervision, as UVA and UVB light can be damaging to your skin if used incorrectly.

Whilst undergoing light therapy, your psoriasis may initially worsen, with increased itching, in response to the treatment, but it should then begin to improve. We would also advise continuing to use topical treatments and creams or gels, but again, you need to be careful when choosing these, as some may produce a negative reaction.

Of course, ideally we would all like to see an improvement in the weather, but in the meantime, light therapy may just help.

    World Psoriasis Day takes place on the 29th of October each year and serves as a podium for people to experience psoriasis to offer their accounts of living with the condition. Though one of the first skin diseases to be recognised psoriasis continues to be misunderstood and those that experience it discover large amounts of misinformation available. World Psoriasis Day is attempting to combat this confusion by encouraging those who experience psoriasis to post pictures of themselves with testimonials.

  • Hug a Vegan This September

    Many consider a vegan lifestyle to be very rewarding and it's certainly easier on our environment. Whether you're aiming to eat nothing that comes from an animal or ensure that you're not using products that use animal products or participate in animal testing, these are all elements that reduce cruelty and pollution. Recent studies have shown that methane from livestock accounts for more greenhouse gasses in the UK than our roads and trains combined! And animal testing accounts for thousands of animals that are forced to endure discomfort for human cosmetic needs. This is why Katharine Botanicals offers a wide range of products that are entirely vegan.

    As the internet makes it easier for conscientious shoppers to make ethical choices, it's also easier than ever to discover the benefits of making these choices when you purchase. In fact, PETA recently held a celebration just for vegans called "hug a vegan day". Last year it was all about vegetarians and now vegans are getting the love from PETA! The official hug a vegan day was held last Friday on the 27th of September but we feel that there is all the time in the world to show your appreciation for all the good things nature has to offer.

  • Sunlight and Benefits to Psoraisis

    Whilst the recent weather has been somewhat unpredictable, we can also say that this has been one of the brightest summers that the UK has enjoyed for some time. This is an excellent opportunity for suffers of psoriasis to enjoy sunlight and the vitamin D that comes with it. Vitamin D and ultra violet light are both completely natural elements that can help to soothe skin suffering from psoriasis. Ultra violet light is already used as a medical treatment by many doctors, where synthesised UVB rays are created with sun lamps. Injections are also utilised to encourage the skin to soak up even more of the beneficial UV light but I’m sure most would rather a natural course of sunbathing. This bright sunshine gives many who live with psoriasis the chance to enjoy a free and completely natural course of UV light and all the benefits that come with it.
