Cold when you wake up Dr. Andrew Huberman from the Huberman Lab Podcast says timing is key. He explains that:
Cold dunking before a workout may also enhance alertness and mental focus.
Cold plunging immediately after a strength session, however, might dull hypertrophy (muscle growth).
Huberman’s tip: If your goal is muscle building, wait 4-6 hours after resistance training before cold plunging_WARN. If you are training for endurance-type exercise, post-training diving may help.
💪 Cold Plunge Before Workout Testosterone: Is There Science Behind It?
Chances are you follow some influencers out there who would tell you that cold plunges “boost testosterone.” Let’s separate fact from myth.
A Japanese study found that men can have temporary boosts in testosterone and sperm quality after cold exposure. But it is a shortterm, modest effect.
🧠 Cold plunges may help support hormonal regulation through improved stress management — not automatically cause your testosterone levels to shoot up overnight.
That said, dipping before workouts might be beneficial by making you mentally sharper and more lovely, which should in turn up your levels of physicality (indirect testosterone spike alert!) and keep fatigue at arms length (again, boosting the gains potential).
🕒 How Long to Cold Plunge on Workout Days: Safe Time and Best Practices
The Sweet Spot The ideal length of a pre-workout cold plunge is short and intense.
✅ Optimal Duration:
Beginners: 2–3 minutes
Experienced users: 5 minutes max
Temperature: 50–59°F (10–15°C)
✅ Timing Before Exercise:
Leave 10-20 minutes in between your dip and when you begin exercising. This allows your muscles to warm back up so that they won’t stiffen.
⚠️ Don’t overdo it — extra time doesn’t bring extra benefit. Too much can leave you weak and prone to injury.

The science of preexercise cold water immersion, let’s take a look.
🧪 Study #1 — Performance When It’s Hot:
A 1999 study by Kay et al. demonstrated that endurance athletes pre-cooling with cold water before an exercise bout in a hot environment achieved significantly longer time to exhaustion.
🧪 Study #2 — Attention and Alertness
A 2023 study in the journal Biology was conducted during an hourlong rest period in which a participant took a five-minute cold bath (68°F) and discovered he/she/they felt more alert, attentive and inspired shortly after.
🧪 Experiment #3 — Power and Muscle Response
A 2014 paper in the European Journal of Applied Physiology found that cold exposure prior to strength-based training diminished muscle output — confirming it’s better for endurance, not strength.
