Is Sauna Good for Pulled Muscles? (How Heat Helps With Recovery)

Saunas are not just for relaxation. Many people use them to ease stiff joints and tired muscles – but are they good for pulled muscles?

Heat is a comfort tool for a healing strain, not a treatment that speeds repair. Used after the acute phase, a sauna or steam room may reduce stiffness and pain for a few hours; used too early, it can make swelling worse. Keep sessions short, drink water and stop if the injured muscle throbs or swells.

Keep reading to find out when heat helps and when it hurts, whether a sauna or steam room is the better choice, and how to use either safely for sore and strained muscles. This article is general information, not medical advice.

Time since the pull	Sauna or steam room?	What helps instead / in addition
0–72 hours (acute: sharp pain, swelling, bruising)	No	Rest, ice or cool packs 15–20 min at a time, light compression, keep the leg or arm raised, pain-free movement
Day 3–7 (dull ache, stiffness, swelling going down)	Yes, gently: 10–15 min, moderate heat, 1 round	Easy walking, light stretching after the heat, plenty of water
Week 2 and later (tight, weak, no swelling)	Yes: normal sessions, 2–3 times a week	Progressive strengthening, stretching, massage; see a doctor or physio if it is not improving
Any time: can’t bear weight, a pop was heard, a dent or large bruise, numbness	No	Get it examined – this may be a tear, not a strain

Does the sauna help with pulled muscles?

A good sweat session can make you feel (and even look) better. The positive impact a sauna has on your mood is convincing enough for me, but does the sauna help with pulled muscles?

Heat may help a pulled muscle once the acute phase is over: warmth widens blood vessels, relaxes the muscle fibres around the strain and lowers the feeling of stiffness, which makes gentle movement easier. Sauna bathing also raises growth hormone briefly in some studies, but that short spike has not been shown to speed up muscle repair, so treat it as a nice side effect rather than a reason to go.

In order for muscles to rebuild, our body needs fluids. Excessive sweating can deplete electrolytes and diminish hydration, so be sure to drink water before and after the session.

Does heat make pulled muscles better or worse?

For thousands of years, heat therapy has been used by many different cultures, including the Egyptians, Greeks, and Romans, who believed in its healing properties. However, is there a downside to using heat for pulled muscles?

Heat may help pulled muscles, but it can also hurt them. The general rule of thumb is that if you are suffering from an acute injury, cool it for the first 48 to 72 hours. Sports-medicine guidance is consistent on this point: avoid heat during that window because it can temporarily increase swelling and inflammation. 

According to a 2013 study, wet sauna bathing can relieve muscle tension. However, that reduced tightness also means you can over-stretch a healing muscle more easily, so keep stretching gentle in the days after the heat.

This elevation in elasticity will be more beneficial once the strain has progressed further in the healing process.

Do steam and humidity make pulled muscles better or worse?

Due to the moisture levels of most saunas, we have to address: do steam and humidity make pulled muscles better or worse?

Heat at any level (dry or wet) is not recommended during the first days of healing. After that, moist heat may be the more comfortable choice because it warms the tissue quickly without drying the skin, while dry heat tends to give longer-lasting relief after the session.

A 2013 study on heat wraps found that moist heat gave relief faster, while dry heat applied for longer kept its effect for more hours afterwards. The difference is about comfort and timing, not about healing faster.

What this means is that from a pain perspective, either works once the acute phase is over; pick the one you find more comfortable and can stay in without pushing the injured area.

Should you use a sauna, infrared sauna, or steam room for sore muscles?

Ultimately, should you use a traditional sauna, infrared sauna, or steam room for sore muscles?

All three may help with ordinary post-workout soreness and with stiffness around a healing strain. Steam rooms are the gentlest (around 110 °F) and the easiest on a sore leg, infrared cabins are warm but not hot and suit longer, calmer sessions, and a traditional sauna gives the strongest heat and the longest-lasting feeling of loosened muscles. None of them has been shown to speed up the healing of a torn muscle fibre.

If you pair either sauna session with light stretching (for sore, not freshly pulled muscles), you can also limit next-day muscle pain. Alternating with cold is popular too; read our take on an ice bath before or after the sauna before you try contrast therapy on an injured muscle.

If the sore area is your lower back rather than a limb, see our separate guide on whether the sauna is good for back pain.

How to use the sauna for sore muscles

The heat and minor humidity of a traditional sauna will still help your sore muscles feel looser.

Follow these steps to use a traditional sauna for sore muscles:

1. Hydrate before and after.
2. Wait at least 48–72 hours after an acute injury.
3. Keep it to 10–15 minutes per round (see how long to stay in a sauna), 2–3 times a week.
4. Add gentle stretching after the heat, not before.
5. Sit on a lower bench where it is cooler, and keep the injured limb relaxed.
6. Use cool packs in 15–20-minute intervals on days you aren’t using the sauna if the area is still puffy.

How to use the steam room for sore muscles

Steam rooms are a gentle option for sore muscles.

Here’s how to use a steam room for sore muscles:

1. Hydrate before and after.
2. Wait at least 48–72 hours after an acute injury.
3. Use 10–15 minutes per session, 2–3 times a week.
4. Add gentle stretching afterwards.
5. Sit rather than stand so the injured muscle stays relaxed.
6. Cool packs on the other days if swelling lingers.

How to use the infrared sauna for sore muscles

Infrared cabins run cooler, so they are easy to tolerate for a longer, calmer session.

To use an infrared sauna for sore muscles:

1. Hydrate before and after.
2. Wait at least 48–72 hours after an acute injury.
3. Use 15–25 minutes per session, 2–3 times a week.
4. Add gentle stretching afterwards.
5. Don’t press the injured muscle directly against a panel.
6. Cool packs on the other days if swelling lingers.

Related Questions

Will the sauna help muscle knots?

The heat from saunas is able to relax muscle fibers and make it easier to get knots out.

The best practice is to combine heat therapy with massage therapy. The sauna is able to loosen your muscles, while physical pressure can help get rid of knots. Drinking enough water after a sauna session is necessary because dehydration can worsen muscle cramps.

What if you have sore muscles after the sauna?

There’s no getting around that after pushing the limits of your body, your muscles will inevitably be sore – whether you use a sauna or not.

However, soreness or cramping specifically after using the sauna (without exercising beforehand) is often linked to fluid and salt loss. If you aren’t increasing your fluid intake, your muscles are more prone to spasms – like the dreaded Charley horse. 

Drink an extra 2–4 glasses of water around each sauna session, with a pinch of salt or an electrolyte drink if you sweat a lot.

What if you have sore muscles after the infrared sauna?

If you have sore muscles after using an infrared sauna, the most likely cause is the same: dehydration.

You may also feel light-headed or achy. Rehydrating usually settles this. Infrared cabins are cooler, but 20–30 minutes is still plenty for most people.

If you feel like this repeatedly, consult your doctor and lower the time spent in your infrared sauna. Always listen to your body so as not to push it too far.

FAQ: sauna and pulled or strained muscles

Is a sauna good for a pulled muscle the day after?

Usually not. One day after a hamstring, calf or thigh pull you are still in the acute phase: the tissue is swollen and the small tears are still bleeding internally. Heat widens the blood vessels and may increase that swelling and the next-day pain. Wait until the sharp pain and swelling settle, typically 48–72 hours, and use cool packs, rest and gentle pain-free movement in the meantime.

A week after a fall, is a sauna or steam room good for a sore thigh?

If the thigh is simply sore and stiff – no new swelling, no large bruise spreading, you can walk normally – gentle heat a week later is generally fine and may make it feel looser. A steam room is the softer start; a short sauna round on a lower bench works too. If the thigh is still swollen, very tender, hard to the touch or you can’t put full weight on it, have it examined first: a fall can cause a deep bruise or tear that heat would make worse.

Does the sauna help a strained muscle heal faster?

There is no good evidence that it does. What heat reliably does is reduce the feeling of stiffness and pain for a few hours and make gentle movement easier, which supports the things that do help healing: pain-free movement, gradual loading and sleep. Think of the sauna as comfort and mobility support, not as a treatment.

Sauna or steam room for a pulled muscle – which is better?

After the acute phase, whichever you tolerate better. The steam room is cooler (about 110 °F) and warms the tissue quickly, so it is the gentler option for a sore leg. A traditional sauna is hotter and its relaxing effect tends to last longer after the session. Infrared cabins sit in between. Keep every option short and leave as soon as the injured muscle starts to throb.

How long should you stay in the sauna with a sore or pulled muscle?

Shorter than usual: 10–15 minutes in a traditional sauna or steam room, 15–25 minutes in an infrared cabin, one or two rounds, 2–3 times a week. Sit on a lower bench, drink water before and after, and do your stretching after the heat rather than before.

When should you see a doctor instead of using the sauna?

If you heard or felt a pop, can’t bear weight or move the joint, see a dent or a large, spreading bruise, have numbness or tingling, or the pain is not improving after a week of rest. Those signs point to a more serious tear that needs an examination, and heat is not the right first step. The same applies if you have a heart condition or take medication that affects blood pressure – ask your doctor before sauna use.

In conclusion, it’s important to know the pros and cons of each kind of sauna to determine if the sauna is good for your pulled muscle.

In order to avoid making swelling worse after an injury, it is recommended that you don’t use any heat therapy within 48–72 hours of the pull. 

Always consult your doctor to make sure the sauna is a sensible choice for your injury!
