Red Blotchy Skin After Infrared Sauna: 9 Possible Causes

Many enjoy infrared saunas for improved circulation, detoxification, and relaxation. However, some experience lingering redness or blotchy skin after a session. If this happens to you, don’t worry – there are usually harmless explanations. 

Infrared heat warms the body gently from within, often bringing a pleasant, rosy glow. For most, any redness fully fades within 30 – 50 minutes. But some deal with prolonged redness, which takes on a blotchy appearance. 

Infrared wavelengths penetrate the skin, boosting circulation and blood flow to superficial vessels. However, temporary temperature increases and exposure to dry heat can exacerbate existing skin issues or cause damage if sessions are not conducted properly.

This article will explore nine potential causes of red blotchy skin after infrared sauna use and provide prevention tips.

Why Does Red Blotchy Skin Occur After Infrared Sauna Use?

Several potential factors can trigger lingering redness or blotchy patches on the skin following an infrared sauna session. Here are 9 causes that I found based on my research:

1. Increased Blood Flow and Circulation

Infrared saunas elevate body temperature, causing the expansion of blood vessels near the skin’s surface. After infrared sauna sessions, this additional blood flow can lead to red blotchy skin. For most, this is a temporary condition indicative of improved circulation.

2. Underlying Skin Conditions

Infrared saunas for eczema and psoriasis users can cause symptoms to be exacerbated due to dry heat activating skin conditions. Thermal stimulation might prolong redness and itchy skin, which underscores the need to carefully manage infrared sauna sessions.

3. Uneven Blood Vessel Dilation

Mottled skin emerges from uneven blood vessel dilation, resulting in a lace-like pattern on the skin. This can be particularly noticeable in individuals with varying skin circulation patterns during exposure to hot environments.

4. Erythema Ab Igne

Regular, prolonged infrared sauna use without adequate breaks can lead to erythema ab igne, a condition marked by skin discoloration and red patches on the skin after the sauna. This underscores the importance of moderating sauna sessions to prevent skin damage.

5. Toasted Skin Syndrome

Excessive exposure to infrared saunas can cause toasted skin syndrome, a severe skin damage from prolonged heat source contact. It is a caution against overuse and highlights the risk of skin lesions.

6. Infrared Dermatitis

Individuals with sensitive skin may experience infrared dermatitis, a type of skin irritation following sauna use. This reaction is due to sensitive skin types’ heightened response to dry heat and infrared exposure.

7. Sensitive Skin Types

Those with sensitive skin are more prone to infrared sauna skin damage, experiencing adverse effects more quickly than others. This group requires shorter sessions and careful monitoring of skin health post-sauna.

8. Prolonged Exposure

Consistently long infrared sauna sessions without proper cooling intervals can escalate the risk of skin conditions like erythema ab igne and toasted skin syndrome, highlighting the need for balanced exposure.

9. Pre-Existing Lesions

Entering a sauna with existing skin lesions or wounds can worsen these conditions, leading to complications. It’s advisable to allow such areas to heal before partaking in heat treatments.

10 Prevention of Red Blotchy Skin After Infrared Sauna

Enjoying the benefits of saunas without the downside of red blotchy skin after infrared sauna use is all about taking the right steps. Here’s how to keep your skin healthy and in top shape while maximizing your infrared sauna session.

  1. Moderate Use:
    Keep those sauna sessions short and sweet. Overdoing it can crank up your body temperature and lead to skin damage. It’s like sunbathing; a little bit is significant, but too much can cause harm.
  2. Hydration:
    Drink up before and after your sauna. Dehydration can mess with blood circulation and slow skin healing, making redness stick around longer. Think of water as your skin’s best friend.
  3. Cooling Down:
    Jump into a cold shower or grab a cool compress after your sauna time. This helps your skin chill out gradually, preventing a shock to your blood vessels.
  4. Monitor Temperature:
    Don’t let things get too hot. If you start feeling overly warm, take a break. Keeping an eye on the heat helps avoid skin irritation from excessive dry heat.
  5. Gentle Exfoliation:
    Treat your skin with care. Rough scrubbing can aggravate sensitive skin, so opt for a softer touch to keep things smooth without causing red patches on skin after sauna.
  6. Skin Care:
    Moisturize with kindness, choosing products without harsh chemicals. Daily hydration keeps your skin’s barrier strong and less prone to irritation from infrared dermatitis.
  7. Clothing Choice:
    After your sauna, go for loose, comfy clothes. Tight or rough fabrics can rub your skin incorrectly, especially if it’s already irritated.
  8. Body Position:
    How you sit matters. Some positions can make you heat up more in certain areas. Pay attention to how your skin feels and adjust to avoid localized skin issues.
  9. Seek Help As Needed:
    If redness hangs around or gets worse, it’s time to see a board-certified dermatologist. They can pinpoint the issue and may suggest effective treatment, like laser treatment, for underlying conditions.
  10. Overall Skin Health:
    Keep an eye on your skin’s overall condition. Skipping sauna sessions when you have cuts or rashes can prevent further complications. It’s all about giving your skin the care it needs to heal.

2 Important Ways to Prevent Skin Issues After Infrared Sauna Use

Navigating the warmth of an infrared sauna requires a smart approach to keep your skin happy and healthy. Let’s talk about two key players: hydration and temperature control. 

1. Hydration: Your First Line of Defense

Why It Matters:
Staying hydrated is crucial. Your body loses water during a sauna session through sweat. This can leave your skin dehydrated, making it more prone to red blotchy skin after infrared sauna use. Hydrated skin heals faster and can better maintain its protective barrier.

What to Do:
Drink plenty of water before stepping into the sauna. Don’t stop there. Keep sipping water during your session and rehydrate generously afterward. Think of water as your skin’s best friend, keeping blood circulation smooth and supporting quick recovery from any temporary redness.

2. Temperature Control: Keeping the Heat Just Right

Understanding the Impact:
Overheating is a big no-no. Excessive heat can stress your skin, leading to infrared sauna skin damage. When your body temperature spikes too high, your blood vessels expand too quickly, sometimes causing red patches on skin after sauna sessions.

How to Manage:
Keep an eye on the sauna’s thermostat. Aim for a comfortable heat setting that allows you to enjoy the benefits of saunas without pushing your skin into the danger zone. 

If you start feeling too warm, take it as a sign to cool off. A cold shower post-sauna isn’t just refreshing; it helps bring your skin temperature down safely, reducing the risk of skin irritation.

Disclaimer: If you’re experiencing persistent skin health issues or have concerns about infrared sauna for eczema, psoriasis, or other medical conditions, consulting with board-certified dermatologists is always the best course of action.

Key Takeaways

Red blotchy skin can sometimes occur after infrared sauna sessions due to increased blood flow and circulation near the skin’s surface. The rise in body temperature from infrared heat causes blood vessels near the skin to expand, leaving some people with redness that lingers longer than 30 minutes.

The heat from the sauna causes blood vessels to dilate, leading to temporary skin redness or a mottled appearance for some. Key things to keep in mind for minimizing this issue include:

  • Hydration is important before, during, and after sauna use to support circulation and skin healing. Dehydration can prolong any redness.
  • Monitor your body’s temperature response. If you start to feel overly warm, take a break or cool down to avoid overstressing the skin.
  • Gradually cool off after sessions, such as with a cold shower, to allow your blood vessels to adjust without going into shock.
  • Be gentle exfoliating skin and choose soothing moisturizers to support the skin barrier and prevent irritation.
  • Seek medical advice if redness persists or worsens, as underlying conditions may need treatment from a dermatologist.
