SORE MUSCLES: Could Sauna Help or Be Good For It?

The human body is a complex machine, capable of performing extraordinary feats of strength and endurance. However, these physical exertions often come with a cost - sore muscles. For centuries, people have sought out various remedies to alleviate this discomfort, and one method that has stood the test of time is the use of saunas. But could sauna therapy truly be beneficial for sore muscles? Let's delve into the science and research behind this age-old practice.

The Science Behind Sore Muscles

Before we explore the potential benefits of sauna therapy, it's important to understand why our muscles become sore in the first place. When we engage in strenuous physical activity, especially something we're not accustomed to, microscopic damage occurs in our muscle fibers. This damage triggers an inflammatory response, leading to pain and stiffness commonly referred to as Delayed Onset Muscle Soreness (DOMS).

Our bodies naturally repair this damage, a process which leads to stronger and more resilient muscles. However, the accompanying soreness can be uncomfortable and even debilitating. It's here that sauna therapy may offer some relief.

The Healing Power of Heat

Heat therapy, or thermotherapy, has been used for centuries to alleviate muscle soreness and promote recovery. The heat helps to increase blood flow, delivering more oxygen and nutrients to the damaged muscle fibers. This can speed up the healing process and reduce the duration of DOMS.

One form of heat therapy that has gained popularity in recent years is sauna therapy. Saunas provide a controlled, high-temperature environment which can induce a state of hyperthermia in the body. This elevated body temperature can have several beneficial effects on muscle recovery.

Increased Blood Flow

As mentioned earlier, heat can help to increase blood flow. When you sit in a sauna, your skin temperature rises, and your blood vessels dilate. This increases circulation, allowing more blood to reach your sore muscles. The increased blood flow not only delivers more nutrients to the muscles but also helps to remove waste products, further aiding in recovery.

Research supports this claim. A study published in the Journal of Science and Medicine in Sport found that sauna use after strenuous exercise increased participants' blood flow and reduced their muscle soreness.

Release of Heat Shock Proteins

Another potential benefit of sauna use is the release of heat shock proteins (HSPs). These proteins are produced by our bodies in response to stress, including heat stress. HSPs help to repair damaged proteins and protect against future damage.

Research has shown that HSPs can help to reduce muscle damage and inflammation, potentially reducing the severity and duration of DOMS. A study published in the Journal of Applied Physiology found that heat stress increased the production of HSPs, and this increase was associated with a reduction in muscle damage.

Considerations and Precautions

While the potential benefits of sauna therapy for sore muscles are promising, it's important to approach this practice with caution. Saunas can be intense environments, and it's crucial to listen to your body and avoid overdoing it.

Here are some considerations and precautions to keep in mind:

  • Stay hydrated: Saunas can cause significant sweating, which can lead to dehydration. Make sure to drink plenty of fluids before, during, and after your sauna session.
  • Start slow: If you're new to sauna therapy, start with shorter sessions and gradually increase your time as your body adapts.
  • Listen to your body: If you start to feel dizzy, nauseous, or otherwise unwell during your sauna session, it's time to get out.
  • Consult your doctor: As with any new therapy, it's important to consult your doctor before starting sauna therapy, especially if you have any underlying health conditions.


So, could sauna therapy be beneficial for sore muscles? The scientific evidence suggests that it could be. Increased blood flow and the release of heat shock proteins may help to alleviate muscle soreness and promote recovery.

However, it's important to remember that everyone's body is different, and what works for one person may not work for another. Always listen to your body and consult your doctor before starting any new therapy.

So, whether you're a seasoned athlete or a weekend warrior, consider giving sauna therapy a try. It could be just what your sore muscles need.
