How Often Should You Do Contrast Therapy?

For most people, one to three contrast therapy sessions a week is a reasonable range for supporting faster recovery. If you're new to the practice, start with once or twice weekly, then work up to a total of three if you tolerate it well.

Keep in mind, research hasn't established a precise optimal frequency, though some studies have looked at when to do it following exercise (usually within 24 to 96 hours of a strenuous workout) to help reduce inflammation.^1,2 Recommendations are more about maintaining safety within a sustainable, personalized wellness routine when using home infrared saunas, ice baths, and other contrast therapy devices.

Understanding what contrast therapy is helps you know why frequency matters in the first place. Ahead, get more details on how often to do contrast therapy, including when to use contrast therapy for different training schedules and one important timing exception to know about.

A Practical Weekly Schedule

Knowing how to do contrast therapy makes it easier to plan how often to fit it in. Let's explore what a weekly schedule might look like for different people doing contrast therapy.

Your Starting Point by Training Level

You can base your frequency on how often or how hard you train:

• Beginner – New to working out or getting back into it after taking some time off exercise? Start with one contrast therapy session a week for the first month or so.
• Regular exerciser – Those who train regularly might start with two weekly sessions, ideally after an especially demanding training routine.
• High training load – If you’re an athlete or do heavier weight training, HIIT (high-intensity interval training), distance running, or other strenuous exercise, start with up to three weekly sessions.

In any case, it's best to begin with moderate temperatures and shorter cycle durations. And only maintain a specific frequency if you're tolerating the therapy well.^3,4 It's always OK to cut down or skip a session.

After a Race or Unusually Hard Effort

How often should you do contrast therapy if you're a long-distance runner? Try one session within 24 to 48 hours of a longer run, whether it's a training day or the actual race. It's different for everyone, but some people feel like it helps with perceived soreness.⁵

The same goes for very steep or technical hikes, long-distance bike rides, whole-body resistance training, and endurance workouts.^6,7,8

Understanding whether contrast therapy is good for you helps explain why it's optional here. Bear in mind, contrast therapy isn't required. It's totally optional, but many people like how it feels and enjoy including it in their routines. There are many components of recovery, including sleep, nutrition, rest, and hydration.⁹

What Counts as One Session

Knowing whether you should do hot or cold therapy first helps you get the order right: heat, then cold. One round of heat exposure followed by cold exposure counts as a single contrast therapy session. And you can do it at home with a hot/cold shower.¹⁰

But if you're up for it, you can do up to three cycles. Each round would include five to 10 minutes of comfortable heat, followed by 30 to 90 seconds of cool or cold water exposure, with a few minutes of rest between each cycle.

Adjust Based on How You Respond

Figuring out the best frequency for your personal needs, goals, and lifestyle may take some trial and fine-tuning over the course of a few weeks.

Try a shorter session with moderate temperatures. See how you feel during, immediately after, and the next day. If your body recovers well, consider adding another weekly session or a couple more cycles to each session.

Signs to Cut Back

You may need shorter or less frequent sessions if you experience:

• Persistent fatigue or poor sleep
• Headaches, dizziness, lightheadedness, or heart palpitations
• Muscle soreness that's getting worse instead of better

Aside from the above, don't hesitate to stop a session if you ever feel uncomfortable. Stopping isn't a failure, everybody's different. When in doubt, ask a healthcare provider before starting contrast therapy.

Two Myths Worth Retiring

Let's touch on a couple of common misconceptions about contrast therapy:

1. More is better – False. Daily - sauna and cold plunge sessions aren't necessary.
2. The hotter/colder the better – False. More intense heat or cold exposure with extreme temperatures isn't known to deliver more benefit. And it could actually pose a safety risk to your cardiovascular health.^11,12

One Timing Exception: Strength & Muscle Growth

Avoid a prolonged cold plunge (or cold water immersion) immediately after a resistance-training session. More research is needed, but some warn that frequent cold exposure following strength work could blunt some training adaptations.^8,13

Use It Strategically Instead

Rather than hopping into an ice bath right after finishing a resistance routine, plan ahead for the ideal time to do a contrast therapy session. This could be after an endurance workout like a distance run or a day or two after a fitness competition, when soreness relief is the actual priority.

This doesn't necessarily mean you need to do fewer weekly sessions. It just might mean a different placement in the week.

Before You Set a Schedule

Consult a healthcare provider before doing contrast therapy (or a standalone sauna session or cold plunge) if you have heart disease or another cardiovascular condition, an irregular heartbeat, uncontrolled blood pressure, circulation problems, Raynaud's phenomenon, or reduced sensation.

Immersive (full-body) hot or cold therapy is also often not recommended during pregnancy, but check with your care team for personalized guidance.^14,15

Find Your Rhythm with Lifepro

Some people may assume more is better with contrast therapy. But this generally isn't the case. A gentle routine you'll repeat two or three times a week beats an intense one you abandon before you start to feel better.

Staying consistent with the ritual often comes down to convenience. If you have to go to a spa or gym to do contrast therapy, it might be tricky to fit it into your schedule. But you can actually do it at home, whether by alternating hot and cold in the shower or with our saunas and recovery ice baths.

The home saunas, portable steam rooms, and cold-therapy equipment from Lifepro are designed for that sustainable, moderate cadence. Explore the lineup and build a weekly rhythm that aligns with your training routine and wellness goals.
