In recent years, cold-plunging has moved beyond elite sports and into the wellness routines of more and more people.
Whether you’re just starting to explore this practice—or you’re already doing cold plunges but want to better understand how it works—this article is for you.
What Is Cold-Plunging and What Is It Used For?
Cold-plunging is a wellness practice that involves deliberate exposure to cold. How? By immersing the body in ice-cold water for a short period of time. Most commonly, cold-plunges are done in water between 13°C to 3°C for 2 to 5 minutes.
Although it’s often associated with elite athletes, many cultures—Nordics, for example—have practiced cold exposure for centuries as part of their way of life.
What’s the goal? To activate a series of physiological processes in the body that generate both physical and mental benefits, including:
-
Increased energy levels
-
Improved circulation
-
Cardiovascular strengthening
-
Reduced inflammation
-
Faster muscle recovery
-
Better mood
All of this happens because cold acts as a controlled stressor, forcing the body to adapt. And those adaptations are exactly what produce the benefits.
What Should You Know Before Starting To Cold-Plunge?
Even though cold-plunging is a simple practice, it shouldn’t be taken lightly. Cold is a powerful stimulus, and three key factors determine whether the experience is safe, effective, and enjoyable.
Temperature
To unlock the benefits of cold exposure, the water temperature should be below 13°C.
The recommendation is to start near that threshold and gradually lower the temperature as your body adapts.
“You’re going to step into cold water that you want to get out of—but you can calm yourself enough to stay in for two or three minutes,” explains Andrew Huberman.
Time
With just 2 minutes of immersion, you can already experience the benefits of cold-plunging. Do not exceed 8 minutes in the water to avoid the risk of hypothermia.
It’s very important not to push yourself or take your body to the limit. Everyone adapts to cold differently. If you’re shaking intensely or feel like you can’t take it anymore, get out and start moving to warm up.
With each session, your body will adapt to the cold, and you’ll naturally be able to extend your time.
Breathing
Breath control is the most important key.
How should you breathe? Inhale deeply through the nose and exhale slowly through the mouth. Make the exhale slightly exaggerated—like you’re blowing on a spoonful of hot soup.
When you focus on your breath, your attention shifts away from the cold. The internal voice saying “I need to get out now” starts to quiet down.
How to Cold-Plunge
Step by step:
-
Relaxation and mindset. Before entering, take 3 deep, controlled breaths. Calm your nerves and avoid going in with fear or anxiety.
-
Hands first. Immerse only your hands for 1 minute. The hands contain many nerve endings and are often the most uncomfortable part. This step helps your body acclimate.
-
Committed immersion. Enter the water smoothly: inhale as you submerge your feet, exhale as you lower your entire body. Don’t stop halfway—pausing makes it much harder.
-
Conscious breathing. Once inside, maintain deep, controlled breathing to regulate your body’s response and calm the mind.
-
Rewarming. After getting out, do light movement for twice the amount of time you spent in the water: squats, horse stance, joint mobility exercises.
Tip: With Alfa Humans ice baths, you can keep your hands and feet out of the water to make the experience more manageable.
Can Everyone Cold-Plunge?
Cold-plunging is safe and beneficial when done in a controlled way. However, it’s not suitable for everyone.
It’s not recommended for people with:
-
Arrhythmias or cardiovascular disease
-
Uncontrolled high blood pressure
-
Asthma or other respiratory conditions
-
Raynaud’s syndrome
-
Epilepsy or neurological disorders
-
Pregnancy (first trimester; afterward only with medical approval)
Whether you have a medical condition or not, consulting a doctor before starting cold-plunging is always a good idea.
Conclusion
Ice-bathing is a simple yet powerful tool to improve energy, recovery, circulation, and mental well-being.
It’s not about “enduring the cold.” It’s about using the right stimulus so the body can adapt and grow stronger.
