For CrossFit athletes, recovery is where the real progress happens. After you’ve pushed through a challenging WOD or heavy lift day, your body needs time and the right conditions to repair, rebuild, and come back stronger. While rest and good nutrition are essential, many athletes add tools like a sauna or cold plunge to their recovery toolkit.
Both have strong followings in the fitness world, and for good reason. Sauna sessions use heat to relax muscles and boost circulation, while cold plunges use cold exposure to ease soreness and reduce inflammation. They work in different ways—but together, they can give you a powerful edge in how you feel and perform.
In this guide, we’ll break down the benefits and how to use each method so you get the most out of your training week.
| Key Takeaways | Details |
| Sauna relaxes muscles | Heat increases blood flow, eases stiffness, and supports recovery |
| Cold plunge reduces soreness | Cold lowers inflammation and swelling but may slow muscle growth if overused |
| Combining both works well | Alternating hot and cold boosts circulation and recovery |
| Timing matters | Best after intense sessions, not every single workout |
The Benefits of the Sauna
The sauna is more than just a place to relax—it’s an active recovery tool. The heat causes your blood vessels to widen, which improves circulation and helps deliver oxygen and nutrients to tired muscles. This can ease stiffness after heavy lifts and help your body clear metabolic waste from training.
Regular sauna use has also been linked to heart health, improved endurance, and stress reduction. Some athletes who use a sauna after resistance training report less soreness and maintain better performance in explosive movements. If you’ve had a week filled with strength sessions or you’re feeling tight, a sauna session could be exactly what your body needs.
The Benefits of the Cold Plunge
A cold plunge, sometimes called cold water immersion, works in the opposite way. When you submerge in cold water, your blood vessels narrow. This helps reduce inflammation and swelling, which can make you feel less sore after an intense workout. Some athletes also say it gives them a mental boost—cold exposure triggers a release of endorphins and adrenaline, leaving you feeling awake and energized.
That said, cold plunging has some nuances. While it’s great for immediate relief after high-intensity training, using it too often right after strength work could slow muscle growth. The key is to use it strategically—saving it for your toughest sessions or when you need to be fresh for another workout soon.
Why Using Both Can Work Even Better
When you combine heat and cold—often called contrast therapy—you create a cycle of expanding and narrowing your blood vessels. This “pump” effect helps improve circulation, flush out waste, and speed up recovery. Athletes who use contrast therapy often report reduced muscle soreness and a quicker return to training.
For example, you might spend 10–15 minutes in the sauna to loosen your muscles, then hop into a cold plunge for 1–3 minutes to reduce inflammation. The switch between hot and cold can also leave you feeling mentally refreshed, which is especially helpful during intense training cycles.
When to Use a Sauna or Cold Plunge (or Both)
Here are some practical ways to fit these tools into your routine:
- After a heavy strength day: Start with the sauna to relax your muscles, then finish with a cold plunge to reduce swelling.
- Following a high-intensity metcon: A cold plunge can provide quick relief from soreness and help you bounce back for your next class.
- On recovery days: A sauna session can increase blood flow without adding more stress to your body.
- Before a competition or event: Contrast therapy can help you feel loose yet refreshed going in.
At Adamas CrossFit, our coaches and nutrition experts can help you decide how to time sauna or cold plunge sessions based on your training plan. Recovery should work with your workouts, not against them.
Recovery Tips from Our Coaching Team
- Personalize your plan: Everyone responds differently. Work with a coach to figure out the best schedule for you.
- Be mindful of timing: Using the sauna or cold plunge is best after hard training days, not after every single session.
- Listen to your body: If you’re feeling run-down, heat may help you relax. If you’re sore and need a quick reset, try the cold plunge.
- Start slow: If you’re new to cold plunging, begin with short sessions and gradually build up your tolerance.
- Stay hydrated: Both heat and cold can stress your system, so hydration is key for safe recovery.
The Bottom Line
Recovery isn’t one-size-fits-all. Some athletes feel their best with regular sauna use. Others swear by the cold plunge after a tough workout. And many find that alternating the two gives them the best of both worlds.
At Adamas CrossFit, we believe your recovery plan should be just as intentional as your training program. By working with our certified coaches, you can find the right mix to keep your performance high and your body feeling great.

FAQs
Can I use the sauna or cold plunge every day?
Sauna can be done more often if you’re healthy and hydrated. Cold plunges are better 2–3 times a week to avoid slowing muscle growth.
Which is better—sauna or cold plunge?
It depends on your goal. The sauna relaxes muscles and improves circulation. Cold plunge helps reduce soreness and swelling.
How long should I stay in each?
Aim for 10–20 minutes in the sauna, and 1–3 minutes in the cold plunge. Adjust based on comfort and experience.
Is one better for recovery after lifting?
The sauna is often better right after lifting. Cold plunge can be used later or on non-strength days to avoid slowing muscle gains.
Can these help with mood or sleep?
Yes. Sauna promotes relaxation and can improve sleep quality. Cold plunge boosts mood and alertness through endorphin release.
