Psoriasis is a long-term autoimmune condition that affects the skin. There is no cure, but treatments, home remedies, and self-care strategies can prevent flare-ups or reduce their severity.

Managing psoriasis might involve using prescribed medications, avoiding triggers, and making other lifestyle changes.

Below, find 11 ways to reduce psoriasis symptoms and prevent them from flaring up in the future.

The best treatment option may vary from person to person. Experimenting and finding the best combination of approaches can help. A dermatologist can provide guidance, and a person might ask which of the strategies below are most likely to be effective for them.

1. Wrap up during cold, dry weather

This type of weather can trigger psoriasis flares.

Scientists do not fully understand why flares are more common in wintry weather, but some research suggests that cold and dark conditions with low humidity cause the skin to thicken and become inflamed.

Wrapping up warm reduces the skin’s exposure to cold, dry air, and this may help prevent winter flare-ups.

2. Keep the skin moisturized

Moisturizing is a key technique for people with psoriasis. This is because dryness can trigger flares and make skin scaling so severe that the skin cracks and bleeds.

A 2016 review notes that moisturizers containing mineral oils, such as liquid paraffin and petrolatum, may be particularly suitable for psoriasis management.

People might also try moisturizing with coconut oil or aloe vera gel, both of which have antibacterial and anti-inflammatory properties.

3. Keep the scalp moisturized

When psoriasis affects the scalp, it is important to keep this area moisturized.

According to the National Psoriasis Foundation, tar shampoos and salicylic acid can help.

4. Use a humidifier

Using a home humidifier helps keep the air moist. This may help moisturize the skin and reduce psoriasis symptoms. A humidifier may be particularly useful in the winter.

5. Get regular exposure to sunlight

UV radiation has immunosuppressive effects. As a result, it may help reduce symptoms of autoimmune conditions, such as psoriasis.

UV light therapy is a treatment option for people with psoriasis. But short, regular exposure to natural sunlight may also help improve psoriasis symptoms and prevent flares. This may be due to the anti-inflammatory and immune-modulating effects of sunlight.

6. Avoid sunburn

Skin damage, including sunburn, is a common cause of psoriasis flares. Wearing sunscreen and limiting time spent in the sun during the hottest part of the day are helpful strategies.

7. Supplement with Vitamin D

Research has suggested that vitamin D deficiency is common in people with psoriasis, particularly in the winter.

While identifying a link between the vitamin and the health condition requires additional research, maintaining sufficient levels of vitamin D may help prevent psoriasis flare-ups.

People can get more vitamin D from:

  • natural sunlight
  • certain foods, such as salmon, milk, and fortified cereals
  • vitamin D supplements

8. Prevent skin injuries

Skin injuries can trigger the development of psoriasis lesions in areas where they are otherwise uncommon. This effect is called the Koebner phenomenon.

Avoiding skin injuries, when possible, may help prevent psoriasis flare-ups. Tips include:

  • taking extra care when cutting the nails or shaving
  • avoiding tattoos or piercings
  • protecting against insect bites
  • taking extra care when preparing food
  • wearing gloves while gardening
  • avoiding dangerous activities and sports

9. Reduce stress

Stress is a potential trigger for psoriasis, and it may lead to flare-ups in 68% of adults with the condition.

Taking steps to reduce stress may help prevent flare-ups. Tips include:

  • avoiding stressful situations
  • practicing yoga, meditation, and other mindfulness and breathing techniques
  • having therapy or counseling

10. Improve the diet

As with many areas of health, the diet may play a role in psoriasis management.

A 2018 review found that dietary interventions can reduce the severity of this condition — particularly focusing on foods that reduce inflammation.

Food triggers for psoriasis may vary from person to person. Trying an elimination diet and recording any improvements in symptoms may help a person identify their triggers.

A calorie-controlled diet may also help improve psoriasis symptoms for people with overweight, while avoiding gluten may reduce the severity of symptoms for people with gluten sensitivity.

11. Avoid certain medications

Some medications may trigger psoriasis flares. A doctor can examine a person’s treatment regimens and identify any medications that may be having this effect, then recommend the best next steps.

The various types of psoriasis, such as plaque psoriasis, guttate psoriasis, and pustular psoriasis, each have different symptoms. The location and extent of affected skin can also influence how the symptoms appear.

Psoriasis often causes dry patches that may be thick, elevated and covered in whitish scales. The patches may also itch. If a person’s skin is lighter, the affected areas may be pinkish. If a person’s skin is darker, the areas may be purple, violet, or gray.

A flare-up involves symptoms worsening. As it subsides, the symptoms may become milder or disappear.

Psoriasis is an autoimmune condition. Certain triggers cause the immune system to release T cells, a type of white blood cell, as a defense mechanism to fight infection.

However, these cells then mistakenly attack the body’s own cells, rather than the invasive pathogen. In someone with psoriasis, this leads to excessive growth of skin cells.

The underlying cause of psoriasis is not clear, but it may be genetic.

Environmental triggers, such as medications, stress, smoking, or an injury, can cause the condition to erupt for the first time, and they can cause existing symptoms to flare. The specific triggers vary from person to person.

The strategies above can help, but it may not be possible to prevent all flare-ups.

Knowing how to manage symptoms when they arise is key. A doctor may recommend:

  • regular moisturizing
  • UV light therapy
  • medicated creams
  • oral medications
  • systemic or biologic medications
