Hot Bathing Water Effects on Psoriasis

It’s been a long day, and it’s almost bath time, the moment you’ve been looking for. But if not done right, it might not be as good for your psoriasis as it sounds in your mind.

There is nothing like a hot bath. It is one of life’s greatest pleasures, especially after a day of hard work.

And… if you work out and sweat, you will find it three times as rewarding.

However, some doctors and experts agree that if the water is too hot, it may do you more harm than good to your skin’s health.

Hot Bathing Water Effects on Psoriasis

Why Does Hot Water Affect Psoriasis?

A scorching shower can aggravate any skin infection.

This is because it removes the skin’s sebum, the fats, and oils needed to keep the skin in tip-top shape. Besides that, it impacts the skin negatively by dehydrating it.

That phenomenon happens right after you get out of the shower, where your fingers look like raisins and wrinkles, meaning a lack of moisture in the dermis.

Water at high temperatures destroys the skin barrier that protects the skin from infectious agents or irritants.

But it’s not just people with skin problems like psoriasis who need to be careful.

Spending long periods of time under a boiling shower can damage the dermis and the hair.

The Effect of Hot Water on Psoriasis

Clearly, if you have psoriasis and the water is too hot, you will only make it worse.

The same applies to conditions such as atopic dermatitis, acne, or cutaneous rose syndrome. Similarly, if you have dehydrated skin, you will only worsen your condition.

If the water is too hot, it will be too harsh on the hair and prevent the shampoo from doing its job and aggravating or triggering scalp psoriasis.

A damaged skin barrier is the main cause of dry skin and the removal of the healthy fats on top of the dermis, composed of cholesterol, fatty acids, and ceramides, which are essential for maintaining good dermatological health.

And it is precisely dry skin that makes the protective lipid layer unable to lock in moisture and keep bacteria or other irritants out.

Ways to Avoid Psoriasis Worsening From Baths and Showers

Even if a hot shower can do more harm than good to psoriasis, it is still important and necessary to shower daily.

However, there are ways to minimize the risks and consequences, such as;

  • Using your hands to cleanse your face gently. Avoid using a loofah, buffing puffs as these can irritate your skin and cause psoriasis flare-ups
  • Rinse the soap or cleanser thoroughly but kindly
  • Blot water from your skin gently with a towel, but leave a small amount of water on your skin so that it feels damp
  • Within five minutes of showering or bathing, gently apply a fragrance-free moisturizer to all of your skin
  • If possible take no more than one bath or shower per day, but don’t neglect hygiene
  • Showers should be no longer than 5 minutes, and baths should be no longer than 15 minutes
  • Only use soft water, avoiding it when hot
  • Use a sensitive-skin-friendly soap or cleanser that is gentle and moisturizing. Stop deodorant soaps and scrubs because they are too rough


In short, the best thing you can do is to avoid having scorching baths and reduce bathing time.

If you take it quickly, you will minimize the damage. Not only that, but you will also gain in quality of life and will be able to minimize psoriasis flares or even prevent them.
