What Are The Risks Of Sun Exposure
As with any source of UV, sunlight comes with some dangers. UVA wavelengths penetrate to the deeper layers of the skin and are largely responsible for the tanning effect of the sun. However, UVA can eventually cause damage to the skin, resulting in the typical signs of photoageing: wrinkles, broken veins, sagging skin and age spots. Meanwhile, UVB is largely responsible for sunburn. It is thought that episodes of severe sunburn, especially in young people, increase the risk of melanoma skin cancer in the future. Also, bad sunburn can cause psoriasis to start where the skin is burned . So, it is wise to gradually expose your skin to the sun in order to avoid sunburn. Excessive lifetime exposure to all wavelengths in sunlight can increase the risks of skin cancers, and this has been illustrated in the great increase in the numbers of skin cancers seen in recent decades since overseas holidays have been affordable and widely available. You are at the highest risk if you are fair and your skin does not tan easily. Always check your skin type for suitable sun care protection.
The Right Amount Of Sun
A weekend at the beach is unlikely to clear up psoriasis, because you need long-term exposure. Too much sun, however, can cause a sunburn and result in injury and aggravation of psoriasis.
Increase your sun exposure levels slowly. That way your skin benefits from exposure to the ultraviolet light, but adapts to the effects of the sun gradually. Start with just 10 minutes at a strong, sunny point of the day, such as noon or 1pm. Gradually increase your exposure by 30-60 seconds a day.
Wear sunscreen and sunglasses to protect yourself from harmful rays that can age you and cause a burn. If you take medications or have a condition that makes you especially sensitive to the sun, clear sun therapy with Dr. Fromowitz before heading outside.
Why Does Psoriasis Suddenly Disappear
Even without treatment, psoriasis may disappear. Spontaneous remission, or remission that occurs without treatment, is also possible. In that case, it’s likely your immune system turned off its attack on your body. This allows the symptoms to fade.Read more

How Often Should You Shower With Psoriasis
Showering or bathing too often can increase the amount of moisture you lose through your skin, making it dry and irritated. It can make already inflamed skin feel even worse, says Dr. Unwala. She suggests bathing once a day and limiting baths to no more than 15 minutes and showers to 5 minutes.
When Should I See A Doctor For Psoriasis
Since psoriasis is a systemic disease of inflammation with dramatic skin involvement, most people should seek medical advice early in its course when symptoms and signs appear. Besides arthritis, people with the condition are more likely to be obese and to have coronary artery disease and/or diabetes. Psoriasis, if limited to small areas of skin, may be an inconvenience for some people. For others, it may be disabling.
- Those with psoriasis commonly recognize that new areas of psoriasis occur within seven to 10 days after the skin has been injured. This has been called the Koebner phenomenon.
- People should always see a doctor if they have psoriasis and develop significant joint pain, stiffness, or deformity. They may be in the reported 5%-10% of individuals with psoriasis who develop psoriatic arthritis and would be a candidate for systemic therapy. Psoriatic arthritis can be crippling and cause permanent deformity.
- Always see a doctor if signs of infection develop. Common signs of infection are red streaks or pus from the red areas, fever with no other cause, or increased pain.
- People need to see a doctor if they have serious side effects from their medications.

What Does Guttate Psoriasis Look Like
Guttate psoriasis is a type of psoriasis that looks like small, salmon-pink drops on the skin. The word guttate is derived from the Latin word gutta, meaning drop. Usually there is a fine scale on the droplike lesion that is much finer than the scales in plaque psoriasis, the most common type of psoriasis.
How Long Can I Expose My Skin To The Sun Before Burning
This depends on many factors, including:
The strength of the sunThis can be assessed by the UV index, announced in summertime weather reports. The UV index is a number representing the strength of the sun, and ranges from 1 to 11+. 1-2 represents low UV, 3-5 moderate UV, 6-7 high UV, 8-10 very high UV and 11+ extreme UV. In the UK the UV index rarely goes above 6 or 7.
Other factors also need to be taken into consideration. For the UK some very approximate guidance can be given on how long individuals can tolerate the sun before burning. Assuming moderate sun strength , and for previously unexposed and currently unprotected skin, then exposure times possible before onset of sunburn are approximately: phototype I, 5-10 minutes phototype II, 10-20 minutes phototype III, 20-30 minutes phototype IV, 40 minutes .
Your sun sensitivityThis is assessed by the Fitzpatrick phototyping scale, which describes how the skin reacts to sun exposure. It was developed in 1975 by Thomas B. Fitzpatrick, the American dermatologist, as a way to classify the typical response of different types of skin to sunlight. The Fitzpatrick scale remains a recognised tool for dermatological research into human skin pigmentation.
What increases the chances of burning?This also depends on many factors, including:
- Which areas of skin are exposed
Scalp, neck, face , upper back and shoulders are more sensitive to the sun than the lower legs.
- How much exposure you have already had
For example, a sunscreen.

What If Those Psoriasis Treatments Dont Work
If psoriasis doesnt improve, your healthcare provider may recommend these treatments:
- Light therapy: UV light at specific wavelengths can decrease skin inflammation and help slow skin cell production.
- PUVA: This treatment combines a medication called psoralen with exposure to a special form of UV light.
- Methotrexate: Providers sometimes recommend this medication for severe cases. It may cause liver disease. If you take it, your provider will monitor you with blood tests. You may need periodic liver biopsies to check your liver health.
- Retinoids: These vitamin A-related drugs can cause side effects, including birth defects.
- Cyclosporine: This medicine can help severe psoriasis. But it may cause high blood pressure and kidney damage.
- Immune therapies: Newer immune therapy medications work by blocking the bodys immune system so it cant jumpstart an autoimmune disease such as psoriasis.
Adverse Effects Of Prolonged Exposure To Sunlight
Haircare experts and dermatologists state that only 10 to 30 minutes a day is enough to benefit from the sun rays without risking your health. However, sometimes this period may be longer due to reasons beyond your control. In such a case, some negative effects can be seen on your hair and skin. These are as follows:
- UV rays exposed for a long time break down hair proteins and thus there occurs splitting in hair
- More active aging of the skin marked by pigmentation and dark spots
- Irritation, sunburn, redness, and tanning on the skin
Therefore, whether the sun is beneficial or harmful for your hair depends entirely on the time you spend. With the right timing, you too can enjoy the incredible benefits of sunlight.

Can Anyone Who Has Psoriasis Use Phototherapy
While dermatologists prescribe phototherapy for many people, it is not recommended for anyone who has:
Had a melanoma or any other type of skin cancer
A medical condition that makes you more likely to develop skin cancer, such as Gorlin syndrome or xeroderma pigmentosum
A medical condition that makes you sensitive to UV light, such as lupus or porphyria
To take medicine that makes them more sensitive to UV light, such as some antibiotics, diuretics, and antifungals
The Role Of Sunlight: How Can It Help Psoriasis
Most people who have psoriasis find that the sun helps to improve their skins appearance. For some the change is dramatic, with red scaly patches almost disappearing altogether during summer months in a warm climate.
In order to help clear psoriasis, sun exposure needs to be spread over time. A week on a sunny holiday may help but rarely completely clears psoriasis, and if the skin is exposed too soon for too long, sunburn can result, which could cause injury to the skin. In some people with psoriasis such injury can start a new plaque of psoriasis at the site of the injury. This is known as Koebnerisation, after the German dermatologist Heinrich Koebner. Therefore it is important to increase exposure to the sun gradually, to allow your skin to adapt to the sun without burning.
Because ultraviolet light is so effective for many with psoriasis, it is often used in various artificial forms. Ultraviolet phototherapy is a highly effective set of treatments for psoriasis given by hospital dermatology departments and specialist phototherapy centres. UV phototherapy is used in one of two forms: UVB or PUVA. UVB uses short-wave UVB light while PUVA uses a plant-derived photosensitiser with long-wave UVA light. If you need these treatments, your GP or healthcare provider can refer you to a dermatologist who will discuss the most suitable treatment for your psoriasis, including phototherapy.

What About Tanning Beds
You may wonder if indoor tanning beds can treat psoriasis. This has been a topic of discussion among the psoriasis community. However, the benefits of tanning beds arent clear. This practice is actively discouraged by many medical groups because it carries an increased risk for skin cancer.
The NPF discourages the use of indoor tanning beds for a variety of reasons. One is that tanning beds generally emit more UVA light than UVB light. UVA light without medication, such as psoralen, is relatively ineffective at treating psoriasis.
Still, some research suggests that indoor tanning beds can help psoriasis. One study concluded that indoor tanning beds may be useful in treating dermatologic conditions for people who are unable to access light therapy prescribed and managed by a doctor. The study encourages doctors to provide guidelines for this practice, as many people try it anyway.
What To Discuss With Your Dermatologist
If you use phototherapy to treat psoriasis, your dermatologist will check you after you have had a certain number of treatments, usually four to six in the beginning. These checkups are essential, so be sure to keep all of your appointments.
During these appointments with your dermatologist, you should tell your dermatologist if you have:
Any side effects
Worsening psoriasis after phototherapy
Missed more than two appointments
If you miss appointments, its unlikely that phototherapy will be helpful for you. Research shows that patients see steady improvement only when they receive phototherapy two to five times per week.

Sun Protection For Psoriasis
Even if you didnÃ¢â¬â¢t have psoriasis, it would be smart to protect your skin from the sunÃ¢â¬â¢s damaging UVA and UVB rays. With psoriasis, you have an extra reason to do so, since sunburn can make it worse. Dermatologists recommend doing these things:
- Avoid being outside during the sunÃ¢â¬â¢s peak hours: 10 a.m. to 2 p.m.
- Wear a broad-brimmed hat, sunglasses that have UV protection, and cover up in light fabrics like cotton that are cool, especially in pale colors.
- Wear sunscreen every day thatÃ¢â¬â¢s Ã¢â¬Åbroad-spectrumÃ¢â¬ï¿½ with an SPF of at least 30.
Because you have psoriasis, you may want to try a fragrance-free sunscreen thatÃ¢â¬â¢s made for sensitive skin. And you can put the sunscreen on in areas where you have psoriasis.
Does The Sun Make Your Hair Thicker
Sun rays in appropriate doses have many positive effects on the human body. Thickening of the hair can also be considered as one of them. When you spend enough time outdoors, you may notice some thickening of your hair over time.However, it should be noted that this is not a miraculous effect. Yes, it has positive effects on hair thickening, but these effects are limited. Therefore, it should not be thought that the problems related to hair thickness can be solved only in this way.

Psoriasis And Vitamin D
Vitamin D can help reduce inflammation throughout your body. The nutrient, as well as the UV rays from light exposure, can help clear or prevent psoriasis plaques. Sunlight triggers your body to make the nutrient, which is beneficial to strong bones and immune function. Vitamin D is a nutrient found in few foods naturally.
A study published in the found that people with psoriasis tend to have low vitamin D levels, particularly in colder seasons. People with low levels of vitamin D can boost their levels by consuming:
- fortified milk and orange juice
- fortified margarine and yogurt
Healing Potential Of Sunlight
Sunlight can resolve many cases of psoriasis, at least temporarily. Some people find their symptoms come close to disappearing during the summer months in warm, sunny climates.
The reason why sunlight is powerful is due to its UVB rays. Sunlight is composed of ultraviolet light, consisting of UVA and UVB rays. The UVB rays slow the rapid rate of skin growth that appears as psoriasis.
Ultraviolet light is so powerful in easing psoriasis symptoms that its used in phototherapy. If you dont live in a sunny climate, a special light box emits the healing rays. Although UVB is the effective wavelength for psoriasis treatment, UVA may be prescribed for phototherapy in combination with medications called psoralens. These medications, applied topically or taken orally, sensitize your skin to the UVA treatment so it works better.
The National Psoriasis Foundation warns against using conventional tanning beds for psoriasis treatment. The wavelengths in these beds contain more UVA than UVB, which increases your risk for photoaging and skin cancer. The UVA rays alone are less effective in easing psoriasis plaques, too.
Is Psoriasis Fungal Or Bacterial
Psoriasis happens due to an overactive immune system that attacks healthy skin cells. This overreaction speeds up the production of new skin cells, causing the symptoms of psoriasis. Candida is a type of yeast that can cause a fungal infection called candidiasis. When this develops in the mouth, it is called thrush.
Should You Treat Psoriasis In A Tanning Bed
Tempted to treat your psoriasis in a tanning bed on your own time rather than during clinic hours with your dermatologist? It’s not a terrible idea, but there are some risks.
Phototherapy, or light therapy, is a psoriasis treatment your dermatologist might recommend as part of your psoriasis treatment plan when other strategies havent helped enough. Exposure to ultraviolet B light can slow the growth of skin cells, essentially turning off your plaque-making mechanism sometimes for up to a year and clearing large areas of psoriasis.
A course of usually involves a series of office visits over several weeks. There are many ways to deliver the light, including by laser, and the exact number of sessions that are needed depends on your doctors approach . For example, German doctors found that three sessions over nine days with a new type of excimer laser delivered safe and effective results.
But not every dermatology clinic has high-powered lasers. And for many people, just getting to the dermatologist as often as phototherapy requires can be a logistical nightmare. Given the financial and time commitment involved, you might wonder whether you can go the do-it-yourself route with a tanning bed.

Get Sun While You Can
Getting sun is a great way to help relieve your psoriasis during the warmer months. Try sunbathing each day for about 5-10 minutes, but dont go beyond 15 because it could cause a sunburn, which can be bad for all of your skin, including your psoriasis patches.
A sunburn can even cause flare-ups, so make sure to wear sunscreen on every part of your body except the patches where your psoriasis occurs and by limiting your sun time to 15 minutes.
