Psoriasis Triggers That Make Your Skin Erupt

Dealing with psoriasis can often feel like walking through a minefield. You have a few fried snacks at a party, and boom, there’s flakes pouring out of your ears! Make another wrong move, and now its your scalp starts mass producing skin like a factory. There are some psoriasis triggers that are personal (i.e. frustrating wives), but there are also other ones, below, that seem to affect everyone.

Stress is the nuclear bomb of psoriasis triggers!

Stress is one of the worst psoriasis triggers

“GRRRUUUUNNGHHH!” grunted Mary as she bit into a delicious laptop

Stress is one of the biggest psoriasis triggers out there, and in fact, many people can trace the beginning of their psoriasis to a particularly nerve-racking period in their life. I know I can; my skin started going off on tantrums when I was in 10th grade, stressing out about all of “LIFE’S BIGGEST PROBLEMS”, and to this day, it tends to get more inflamed than usual when I am stressing over work, deadline or other worries.

The reason is simple, when you’re stressed, your body reacts in ways that increase inflammation. Studies have been done that link stress and general anxiety to psoriasis flare-ups, but this won’t probably come as a surprise to you.

The biggest challenge is that its a catch-22 situation: psoriasis makes you stressed and stressing makes psoriasis worse. So how do you deal with it? I’m not going to sprout crap like “breathe deep and count to 10 when your house is getting repossessed”, but I will say that you need to watch all the other little things that can go hand-in-hand with stress, such as slugging gallons of coffee and eating fast food, as all those things combined will make your skin weep little flakelets.


Smoking is another one of the most common psoriasis triggers

Gary would often wonder why his psoriasis was bad as he went outside for his 20th smoke break

Smoking is a bad idea if you have psoriasis, because the more you light up, the worse it gets! Studies have demonstrated this time and time again, and my personal experience goes along with their results.

I smoked quite heavily during my first year of uni and my skin looked like someone had taken a grater to a baboon’s ass.

The good news is that reducing the amount you smoke, or kicking the habit if you can, will often have a very significant effect on your psoriasis. Some have even found that their psoriasis disappeared – like a wisp of smoke – when they stopped.

Studies have also been done that show smokers are more likely to develop palmoplantar psoriasis (the pus filled kind), and this is because nicotine binds with T-cells in your immune system. They essentially tell your skin cells to hurry up and flake already! And you don’t want that unless you’re a skin pervert.


Alcohol is another one of those universal psoriasis triggers that tips everyone over the edge. So if you’re wondering if you should do that line of 10  tequila shots, the answer is: you will pay, boy.

Alcohol makes your skin weep

If you think this is bad, John, wait until your flare-up in the morning

One  study from Harvard Medical School and Brigham and Women’s Hospital found that psoriasis was really exacerbated when people drank non-light beer in particular. However, others say that most alcohol is off-limits, except for minuscule amounts of red wine and the like.

I won’t tell you to stop drinking, because that would be hypocritical. I also drink to make the pain of 21st century living go away, and my recommendation is that you should slug a pool-sized amount of water and take a couple of high strength painkillers before you pass out. And don’t mix, mixing leads to horrid flare-ups.

Skin cuts and other injuries

People with psoriasis really need to watch themselves when it comes to scrapes and bruises, because instead of healing, they can often magically transform into brand new patches of psoriasis.

Cuts and scrapes can lead to the Koebner phenomenon

“Oh no! Not the Koebner effect!” thought Mary as she deep-fried her digits

This phenomenon was first described by Heinrich Koebner in 1872 after he noticed that one of his patients with psoriasis had it spread to his arm when a horse bit it. This relationship between skin injury and new psoriatic lesions has been observed to occur in up to 50% of patients.

The types of skin trauma which can cause new lesions to pop up are far and wide, including cuts, burns, scratches, tattoos, shaving, harsh chemicals and more. I even read a case in the New England Journal of Medicine about a 73 year old man that developed new psoriasis patches when he was getting acupuncture!

As a clumsy person who hurts himself on a daily basis, I can attest to this. Just last week I burned myself cooking eggs and the area is turning suspiciously red and verging on flaking.


Infections can cause psoriasis outbreaks

Barry, who’s had psoriasis for 40 years, swears by his gas mask to keep him from getting infections

There are some who say that certain infections can worsen psoriasis. Thrush, strep throat and yeast infections are the common ones that will make your epidermic volcano erupt flakes, but other, less known ones include boils (yes, it didn’t die out in the Middle Ages) and some upper-respiratory infections.

Personally, I used to get colds quite often in the past, and my psoriasis always went downhill whenever I did. The good news is that most infections are quite easy and quick to treat with antibiotics, and flare-ups normally calm down quickly when they’re gone. It’s not one of the universal psoriasis triggers, but it is quite common.

Cold and dry weather

Cold weather is terrible for psoriasis

“I’m not sure if this is a good idea” thought Ben as he looked down at his chapped willy

Winter is the worst season in the psoriasis calendar. Trust me, I know what I’m talking about – I used to live in a country where I turned into a walking, human popsicle every time it came around. I’m talking about -60°C temperatures, when most things on Earth shrivel up and die.

The biggest problem is that cold weather is dry weather, which strips your skin of essential moisture, leaving it a ragtag collection of flakes. Those big, coin sized pieces that are so fun to pull off and yet so bad to look at. The other negative is that cold weather means that most people will have their central heating systems and radiators on full blast, further drying up your skin.

Your only weapon is nice, warm fur and plenty of moisturiser. Moisturise your body within an inch of your life, until your skin can’t take any more. And then moisturise some more!

What other psoriasis triggers would you add to the list? Add it below and I’ll make sure to include it!

I'm just an average 28 year old living with psoriasis. Over the last decade, I've tried everything, from real snake poison to rubbing banana peels over my body. I've finally found an approach that's working for me, and I'm sharing it with all the flakers out there. But Psoriasis Blob is not about one man, it's a growing community of great, red people.

    I usually only get flare ups when I don’t sleep enough (goes back to your stress statement). I usually drink 2 cups of espresso with cream a day, so coffee doesn’t seem to effect me. Doctor gave me cream that did nothing… The best thing I’ve found is pealing an aloe leaf and rubbing the inside on the patches, and they are gone in a few days. I think exposing to sun also helps (for me anyway – that goes back to someone’s vit D statement). My psoriasis usually only appears on my legs and arms (both usually covered during the day)

    Glycerin and aloe works and its cheap…can be gotten at the supermarket…they should mix thay circumin with glyerin and aloe.

    The turmeric and black pepper advice I found to be very accurate along with most everything on this site. It seems psoriasis is a skin oversensitivity that may be remnants of a caveman’s adaptation to disease. Yes, I have studied it and do believe it’s a liver problem as well. Any buildup of foreigners toxin or allergen is going to affect the liver or spleen and some are more sensitive. You know though only 30% are hereditary leading to a combination of causes: ancient mutations, mutations during a lifetime, changes in diet, lifestyle, liver or spleen damage. Scientists say some people have yet to evolve to process the modern diet. Interestingly, there appears to be a diet adapted to each blood type and I believe that may be true. So yeah, high vegetable diet, fresh, low salt, too much fats, not enough vitamin D and magnesium or uv light, potassium (healing, water in cells, stress), excess sodium, avoiding toxins and irritants and excess stress is important. Anger or emotions like worry probably irritates it by affecting the liver and spleen. Finally, a regular sauna or hot shower helps a lot to remove toxins from sweat and skin. The skin breathes from inside the body, the liver, the air, and out…. I’ve studied the disease. The liver filters fat and toxins, the spleen makes cells to fight inflammation, and the kidneys help activate vitamin D using magnesium.
    I used to work in research.

    Thinking about psoriasis can also cause flare ups, lol! I’ve had paresthesias for about 8 months (they’re gone now). These were warning signs that flare ups would be coming, and I usually got them during awkward social situations hahaha! I dont know what I did, but they eventually went away, just like my athritis. Thank God!!!

  5. So stop eating meat, fruit, grain, dairy seafood etc. And my psoriasis will clear? Gahhhh is that because it won’t be an issue when I die of malnourishment? What are you guys eating? I need help!

    • redblob says:

      Hahaha, you’ve cracked it 😉 Yeah it can feel like that at times… but saying that you’d be surprised what kind of wonders can be knocked up with half a carrot, some onions and two leaves of lettuce.

    • Andy says:

      Firstly have an allergy scan to eliminate any obvious ones your body doesn’t like. Also restore your gut bacteria with daily tablet. No alcohol, no bread etc and no dairy will really help

  6. i’m a light smoker .. i smoke from 6 to 8 smokes per day . Is it a bad idea ?? i tried quitting .. the stress involved during the withdrawal also results in flare ups .

    dont know what to do . I have cut down coffee intake to zero .

    Stopped eating Meat and sea foods .

    Does coffee cause flares?

    • redblob says:

      In my experience, it does. Coffee has a diuretic effect, but saying that, there are many variables. Do you drink it with milk, and does your P get worse with milk? What about sugar? Having a black coffee once in a while ain’t so bad.

  8. S. Gustavus says:

    Spicy and greasy foods, as well as all things you listed, cause mine to flare up like mad.
