Should You Cold Plunge After a Workout? When to Plunge for the Best Results

The short answer: It depends on your workout. After cardio, like walking, running, cycling or swimming, a cold plunge right away is fine and can help you feel less sore. After strength training, like lifting weights, it’s better to wait at least a few hours, or plunge on a different day, because plunging right after lifting may slow muscle growth over time.

Why timing matters

When you exercise, your body has a natural recovery process. Muscles get a little inflamed, blood rushes in, and your body starts repairing and getting stronger.

Cold water slows that process down. That’s why a cold plunge feels so good on sore muscles. But it also means that if your goal is building strength or muscle, plunging too soon after a workout can work against you.

After cardio: plunge anytime

If you’ve just finished a walk, run, bike ride, swim or tennis match, a cold plunge right afterward is a great choice. It can:

• Help muscles feel less sore the next day
• Cool your body down quickly, especially on hot days
• Leave you feeling refreshed and alert

This is also helpful if you’re doing two workouts close together, like a tournament or back-to-back training days, where feeling recovered quickly matters most.

After strength training: wait a while

If you lift weights or do resistance training to build strength or muscle, it’s best to give your body time first. A study published in The Journal of Physiology found that people who used cold water right after strength training gained less muscle and strength over several weeks than people who recovered without the cold.

You don’t have to give up plunging. You can:

• Wait at least a few hours after lifting before you plunge
• Plunge in the morning and lift later in the day
• Plunge on your rest days instead
• Plunge before your workout for a quick energy boost

What if you just want to feel good?

Not everyone exercises to build muscle. If your main goals are feeling less sore, sleeping better, or simply enjoying the routine, plunging after any workout is fine. The best timing is the one you’ll stick with.

How long and how cold after a workout?

Most people do well with water between 50°F and 59°F for 2 to 5 minutes. Beginners can start with 30 seconds to a minute and build up over time. Colder isn’t always better, so there’s no need to start at the lowest setting.  For more tips read our beginners guide:  How Cold, How Long and How Often.

Try contrast therapy

Many people like to alternate hot and cold after exercise. A few minutes in warm water followed by a short cold plunge can feel relaxing on tired muscles. Repeat a few rounds and finish on whichever feels best to you.

A quick safety note

Cold water raises your heart rate and blood pressure for a short time. If you have a heart condition, high blood pressure, or other health concerns, check with your doctor before you start cold plunging.
