Ever noticed that blotchy red or white pattern on your skin after a sauna session?

These could be due to the expansion of blood vessels and increased blood circulation caused by the heat in the sauna. It's generally harmless and can even lead to improved skin health.

Other causes that may not be sauna-related are; acute urticaria or hives, which could also result in itchy, red lumps on the skin - but you don't have to worry! You can look out for certain signs which will tell you whether reactions are severe or not.

We recognise the understandable concern that may arise from such a reaction. Hence, this blog aims to address all your inquiries regarding post-sauna skincare concerns.

We have included relevant links to resources and medical papers, ensuring that you can access accurate and helpful information directly from the source. Rest assured that the details provided here are both reliable and beneficial.

Why do my legs look blotchy after sauna?

After a sauna session, you might notice blotchy red or white patterns on your skin. This could be due to the expansion of blood vessels and increased blood circulation caused by the heat of the sauna.

It's generally harmless and often a result of your body's cooling mechanisms. There are two main terms for this skin reaction to heat:

Toasted skin syndrome, also known as erythema ab igne is a condition that causes skin discolouration, itching, and burning sensations due to prolonged exposure to low-grade heat sources.

Common modern causes of toasted skin syndrome include using laptops on thighs, seat heaters in cars, heating pads or hot water bottles, and space heaters.

Mottled skin, also known as livedo reticularis, is a temporary condition caused by disrupted blood flow to the tiny vessels under the skin. It results in a lace-like pattern of bluish-red discolouration.

There are different types of livedo reticularis causes including; physiological (due to cold exposure), primary (unknown reasons), and secondary (complication of underlying medical conditions).

Other terms for this condition include congenital livedo reticularis, erythema ab igne, idiopathic livedo reticularis, and livedo racemosa. However, for the purpose of this blog, our focus will be on discussing skin redness that occurs after sauna use, excluding these specific causes.

If you believe you have a more underlying health issue causing your mottled skin, it is recommended to seek medical advice.

In the instance of red, blotchy patches of skin post-sauna session, especially on your thighs or legs, chances are it's the opening of capillaries and additional blood flow to the normally poor circulated areas.

Treatment when mottled skin occurs

If your symptoms of mottled skin are infrared sauna-related, the best source of treatment is to rest, gently cool down and monitor if it goes away naturally.

Unless you have an underlying medical condition, the skin rash which appears is likely caused by the increased blood circulation and vessel dilation and will subside naturally.

How to avoid mottled skin: Blood flow, blood vessels, and blood circulation

If you are experiencing rashes after sauna bathing on your thighs and arms, more likely than not it's due to poor circulation. It is common in most people who do not regularly exercise and who do not regularly participate in saunas or a steam room.

If this is you, and you want to continue using your sauna without having the mottled skin experience, the best thing to do is to gently and regularly continue sauna bathing consistently over a long period of time.

This will improve your circulation to those areas, and open up healthy pathways for your blood flow to work optimally both during and after your sauna sessions.

Another way is to support this blood flow to those areas by stimulating your lymphatic system with a lymphatic massage or compression massage.

You can also tailor workouts to target those areas of your body to help open up those pathways. Eating anti-inflammatory foods and maintaining a healthy diet will also contribute to your body's ability to regulate blood circulation thus lowering the severity of your redness post sauna sessions!

Are infrared saunas worse for blotchy skin?

When it comes to infrared saunas versus traditional saunas or even a steam room for the blotchy skin reaction, there is no difference. This is because the blotchiness comes from warmth and not the application. Some people experience blotchy skin after a hot shower or bath!

What may help with infrared saunas is that they use infrared heaters to heat the body directly, helping to evenly distribute heat without causing extreme temperatures.

This could potentially aid in preventing blotchiness, as it promotes healthy circulation and helps to regulate the skin's temperature without over-exerting the skin.

Moreover, using infrared saunas regularly can help flush toxins from your body through sweating, which can improve your overall health. Just remember to wash your skin gently afterwards to remove sweat from open pores.

Should you be worried about blotchy skin after sauna?

In conclusion, the appearance of blotchy skin after a sauna session is generally a normal response of the body to heat.

It's mainly due to increased blood circulation and the dilation of blood vessels. While it may be alarming at first, these skin changes are often harmless and subside naturally.

Regular sauna use may actually improve your circulation over time, potentially reducing the occurrence of these blotches.

For those with persistent issues, a consultation with a health professional is recommended. As always, it's crucial to listen to your body and treat it with respect.

Remember, the key to any sauna experience is relaxation and enjoyment. Stay hydrated, stay safe, and embrace the many health benefits that saunas provide.

Frequently Asked Questions

Why does my skin turn red and blotchy after using a sauna?

After a session in an infrared sauna, you might notice your skin turning red and blotchy. This is due to the dry heat in the sauna leading to increased circulation, causing blood vessels to dilate. It's a natural response and typically subsides once your body cools down.

Is it normal for my skin to appear flushed after using a sauna?

Yes, it's perfectly normal. The heightened blood flow from the increased circulation can make your skin's surface appear red or blotchy after using any type of heat therapy. This is a sign that your body is responding to the heat therapy as it should.

What is mottled skin and why do I get it from using a sauna?

Mottled skin, which appears as a lace-like pattern on the skin's surface, may be experienced by some individuals, especially young women, during a sauna session. This is due to improved blood circulation and is usually harmless.

Should I consult a doctor for skin mottling after sauna use?

While skin mottling can be a harmless side effect of using saunas, if you're experiencing other symptoms or have an underlying condition, we advise you to consult a doctor for proper evaluation and treatment.

Why does my skin warm up quickly and become red in the sauna?

Certain skin types may be more prone to developing redness or blotchiness after sauna sessions, as their skin warms up quickly in response to the heat. This is a normal reaction and should not cause any concern.

Can sauna use exacerbate conditions like idiopathic livedo reticularis?

If you have an underlying condition like idiopathic livedo reticularis, sauna use could potentially exacerbate the symptoms and cause your skin to appear mottled. Always be aware of how your body reacts to heat therapy.

What causes the dilation of blood vessels in infrared saunas?

Infrared Saunas use dry heat that can lead to the dilation of blood vessels and increased blood flow, contributing to redness and blotchiness on the skin's surface. This is a normal physiological response.

How can I alleviate skin redness after using a sauna?

Hydrating well by drinking enough water before and after your sauna session can help maintain your body's moisture levels, potentially alleviating redness and blotchiness on your skin.

Can dehydration cause skin redness after sauna use?

The dry heat in saunas can sometimes result in very little humidity, which can lead to dehydration. Staying well hydrated can help mitigate the redness and mottled skin that occurs.

Why should I wash my body thoroughly after using a sauna?

If your skin looks blotchy after using a sauna, it's crucial to wash your body thoroughly to remove toxins and sweat that may have accumulated on your skin's surface during the session.

Are there any side effects of using a sauna?

While sauna sessions can have beneficial effects on your health, including relaxation and improved circulation, they can also lead to temporary redness and blotchiness as a result of the heat.

Can sweating in a sauna cause skin discomfort?

Yes, the heat in saunas causes your body to sweat, which is a natural way to release toxins. However, this sweating can sometimes result in skin redness and discomfort.

Should I consult a dermatologist for persistent skin redness?

If you're experiencing persistent skin symptoms like redness after using saunas, we recommend consulting with a dermatologist to rule out any underlying skin conditions.

How can I alleviate my skin's redness after a sauna session?

Taking a cool shower after your sauna session can help lower your body temperature and close your pores, which can alleviate the redness and blotchiness of your skin.

Can applying a moisturiser improve dry skin after using a sauna?

Absolutely! Dry skin, a common side effect of saunas, can be improved by applying a moisturizer post-session. This will help lock in moisture and prevent skin irritation.

Are there any health benefits to using a sauna?

Definitely! Sauna use can have numerous health benefits, such as improving blood circulation and releasing toxins from your body. However, it's essential to be aware of the potential side effects of temporary redness on your skin.

Can certain medications or supplements minimise skin redness after a sauna session?

To minimise the appearance of redness and blotchiness on your skin after a sauna session, you might consider taking certain medications or supplements recommended by your doctor.

Is the redness and mottled skin caused by sauna use temporary?

Yes, the redness and mottled skin that occurs after using a sauna is typically a temporary effect caused by the heat and increased circulation. It should subside as your body cools down.

Should I consult a medical professional for persistent skin redness after sauna use?

If you experience persistent or severe redness and blotchiness after sauna use, it's crucial to consult with a medical professional to rule out any underlying conditions that may be affecting your skin's reaction to heat therapy.
