Cold plunging has moved from fringe practice to mainstream wellness tool, supported by growing scientific research and endorsed by experts like Wim Hof, Dr. Susanna Søberg, and Dr. Andrew Huberman. For beginners, the idea of stepping into icy water can feel intimidating. The good news? You don’t need extreme exposure or daily ice baths to benefit.
Research suggests that as little as 11 minutes of cold exposure per week can deliver meaningful physical and mental health benefits when practiced correctly.
This guide breaks down everything beginners need to know—what cold plunging is, why it works, how to do it safely, and how to build a sustainable practice backed by science.
What Is Cold Plunging?
Cold plunging refers to deliberate immersion of the body in cold water, typically between 4–15°C (39–59°F), for short, controlled periods. It is a form of cold exposure therapy that activates powerful physiological and neurological responses designed to enhance resilience and recovery.
Cold exposure has been used for centuries across cultures, from Nordic ice bathing to Japanese Misogi rituals and Eastern European winter swimming traditions.
Why Cold Plunging Works (The Science)
Cold plunging works by triggering the body’s acute stress response, followed by rapid adaptation.
Key physiological effects include:
- Peripheral vasoconstriction followed by rebound vasodilation
- Activation of brown adipose tissue (BAT)
- Increased norepinephrine and dopamine release
- Improved insulin sensitivity
- Nervous system regulation via vagal tone
Dr. Andrew Huberman explains that cold exposure significantly increases dopamine levels—by up to 250% above baseline—with effects lasting hours after exposure. Source: Huberman Lab

The 11-Minute Rule: Why Less Is More
One of the most important breakthroughs in cold exposure research is the realization that volume matters more than intensity.
Dr. Søberg’s work suggests:
- ~11 minutes of total cold exposure per week
- Spread across 3–4 sessions
- Yields metabolic, immune, and mood benefits
This means beginners do not need extreme temperatures or long durations to benefit.
Cold Plunge Benefits for Beginners
Physical Benefits
- Reduced inflammation and soreness
- Improved circulation
- Enhanced recovery
- Increased cold tolerance
Mental & Emotional Benefits
- Improved stress resilience
- Reduced anxiety symptoms
- Increased mental clarity
- Elevated mood via dopamine release
Metabolic & Immune Benefits
- Activation of brown fat
- Improved insulin sensitivity
- Potential immune modulation
How Cold Plunging Affects the Nervous System
Cold plunging trains the nervous system to tolerate stress without panic. Controlled breathing during cold exposure shifts the body from sympathetic (“fight or flight”) into parasympathetic recovery once the exposure ends.
This nervous system adaptability is one reason cold plunging is increasingly used for:
- Anxiety regulation
- Burnout recovery
- Emotional resilience
How to Start Cold Plunging (Beginner Protocol)
Temperature
Start between 10–15°C (50–59°F).
Duration
- Week 1–2: 30–60 seconds
- Week 3–4: 1–2 minutes
- Progress gradually
Frequency
- 2–4 sessions per week
- Total weekly exposure ≈ 11 minutes
Breathing Techniques for Cold Plunging
Breathing is critical. Recommended approach:
- Nasal breathing
- Long, slow exhales
- No breath-holding while submerged

Cold Plunge vs Cold Showers for Beginners
Cold showers are a great entry point but lack:
- Full-body immersion
- Consistent temperature
- Measurable exposure control
Cold plunges provide more predictable, research-aligned exposure.
Safety Guidelines for Beginners
Avoid cold plunging if you have:
- Uncontrolled cardiovascular conditions
- Severe Raynaud’s syndrome
- Acute illness or fever
Always:
- Warm up naturally afterward
- Avoid alcohol before or after
- Exit immediately if dizziness or numbness occurs
Common Beginner Mistakes
- Going too cold too fast
- Staying in too long
- Poor breathing
- Skipping warm recovery
Consistency beats intensity.
Frequently Asked Questions (Q & A)
Q: Is cold plunging safe for beginners?
A: Yes, when started gradually with controlled temperatures and durations.
Q: How cold should the water be for beginners?
A: 10–15°C (50–59°F).
Q: How long should I stay in a cold plunge?
A: 30 seconds to 3 minutes depending on experience.
Q: How many minutes per week do I need?
A: Approximately 11 minutes total.
Q: Can cold plunging boost immunity?
A: Research suggests improved immune regulation with consistent practice.

A: Yes, through nervous system regulation.
Q: Can beginners cold plunge every day?
A: Yes, with short sessions and proper recovery.
Q: Should I cold plunge after workouts?
A: It depends on training goals; avoid immediately after strength training if hypertrophy is the goal.
Q: Is cold plunging better than cold showers?
A: Cold plunges provide more consistent exposure.
Q: What breathing technique should I use?
A: Slow nasal breathing with long exhales.
Q: Can cold plunging help with weight loss?
A: It supports metabolic health but is not a standalone solution.
Q: Is shivering dangerous?
A: Mild shivering is normal; intense shivering means exit.
