Understanding the Søeberg Principle

What is the Søeberg Principle?

The Søeberg Principle encourages you to finish cold exposure without immediately heating up.
Instead of jumping into a hot shower or sauna right away, you let your body naturally re-warm.
This “End with Cold” approach makes your system work harder, creating adaptive benefits.
It’s about embracing the mild discomfort of shivering to unlock health improvements.

Dr. Susanna Søberg and Her Pioneering Research in Cold Therapy

Dr. Susanna Søberg is a Danish researcher known for her work on cold exposure.
Her studies explore how cold immersion activates brown fat, improves metabolism and supports health.
She promotes deliberate cold exposure protocols that include allowing the body to shiver.
Timing and natural re-warming are key to these benefits.

The Core Concept: Natural Reheating, "End with Cold," and Shivering Response

The idea is straightforward: finish cold and avoid rapid re-warming.
Shivering is part of the therapeutic process.
It activates brown fat, burns calories, and improves thermogenesis.
This approach is essential for unlocking cold therapy’s full effects.

The Science Behind the Principle

The Power of Shivering: Brown Fat Activation and Enhanced Metabolism

Shivering activates brown fat, which burns energy to produce heat.
This process improves metabolic health and may boost insulin sensitivity.
It’s a hormetic stress—mild and beneficial over time.
Cold exposure helps the body regulate temperature better.

Neurotransmitter Release: The Role of Dopamine, Epinephrine, and Norepinephrine

Cold exposure raises neurotransmitters like dopamine and norepinephrine.
These chemicals improve mood, focus, and alertness.
They also help build stress resilience.
The result is sharper thinking and better well-being.

Comprehensive Benefits of the Søeberg Principle

Health and Wellness Advantages

Enhancing Metabolic Health: Brown Fat Activation, Calorie Burning, and Insulin Sensitivity

Cold exposure increases brown fat activity.
This burns calories and supports healthy glucose metabolism.
Regular practice can improve metabolic health overall.
It’s a natural method for weight management support.

Boosting Mental Resilience, Mood Elevation, and Improved Focus

Cold plunges enhance mental toughness.
They elevate mood by increasing dopamine levels.
They also sharpen focus and aid stress management.
This builds resilience for daily challenges.

Physical Performance and Recovery

Optimising Post-Exercise Recovery and Reducing Muscle Soreness

Cold immersion helps reduce muscle soreness after workouts.
It manages inflammation and speeds up recovery.
Athletes use it to maintain training consistency.
It’s a solid addition to any recovery routine.

3.2.2 Strategic Timing for Athletes and Muscle Growth

Timing is key with cold exposure.
Post-exercise plunges help manage inflammation for recovery.
However, too much cold too soon may reduce muscle growth signals.
Athletes can adjust timing based on their goals.

Implementing the Søeberg Principle: Practical Guidelines

Protocols for Deliberate Cold Exposure and Contrast Therapy

Recommended Duration and Frequency (e.g., the 11-minute Weekly Guideline)

Dr. Søberg suggests around 11 minutes total cold exposure weekly.
This can be divided into several sessions.
Consistency is more important than extremes.
Aim for sustainable, regular habits.

Different Methods: Cold Showers, Ice Baths, and Cold Water Immersion

You can choose Cold Plunge Tubs, Ice Bath Tubs, or even cold showers.
Each option has its advantages and accessibility.
Pick what suits your space and comfort level.
All promote adaptation when used well.

Integrating with Heat Exposure: Sauna Use and the "End on Cold" Strategy

Contrast therapy pairs hot and cold.
Saunas relax muscles and improve circulation.
Ending with cold maintains adaptive stress.
This combination enhances the overall benefits.

Safety Considerations and Tips for Beginners

Gradual Adaptation and Listening to Your Body's Signals

Start with short exposures—even 30 seconds.
Notice how your body reacts.
Increase duration gradually over time.
Your system will adapt with practice.

Important Precautions and When to Consult a Professional

If you have heart conditions or other health issues, consult a professional first.
Avoid cold plunging alone, especially when starting out.
Know the signs of hypothermia or extreme discomfort.
Stay safe while building resilience.

Takeaways

  • The Søeberg Principle is about finishing cold and letting your body naturally reheat.

  • Benefits include boosted metabolism, better focus, and stress resilience.

  • Cold Plunge Tubs, Ice Bath Tubs, and showers can all be used.

  • Start slow, stay safe, and enjoy the healthy boost!

Conclusion
The Søeberg Principle offers a simple yet powerful approach to cold therapy.
By ending cold and letting your body do the work, you unlock real adaptive benefits.
Ready to shiver your way to better health?

Steamy Shower Steam Room

Can Steam Room Cause Spots?

Ever left a Steam Room feeling like a glowing goddess—only to wake up with surprise spots? Steam Bath bliss can backfire! Short answer: Yes, steam rooms can cause spots if your skincare routine misses a step. Keep reading to find out why—and how to keep the glow, not the pimples. The Surprising Truth: Can Steam Rooms Really Cause Spots? Steam rooms are often praised for boosting relaxation and leaving your skin glowing.But for some people, that post-steam glow turns into a breakout the next day. The reality is this: yes, steam rooms can cause spots if the skin isn’t properly prepared or cleansed.The mix of heat, sweat, and surface dirt can become a recipe for clogged pores.Still, with the right approach, you can enjoy a steam without the blemishes. The Pros: How Steam Can Benefit Your Skin Steam isn't all bad—in fact, it can be brilliant when used well. Deep Cleansing: How Sweat Works Steam encourages your body to sweat, which helps lift dirt, oil, and debris from the skin’s surface.This can aid in unblocking pores and gently flushing impurities.For many, this results in a fresher, cleaner feeling post-session. Hydration vs. Dehydration: The Steam Room's Role Steam makes the skin feel dewy—but this is often superficial.In reality, it draws water out from your body.If you don’t rehydrate afterwards, skin can end up feeling tight or even dry. Drinking water and applying a light, non-comedogenic moisturiser can help restore balance. The Stress Factor: Reducing Cortisol for Clearer Skin Steam can also help reduce cortisol, the hormone linked to stress and inflammation.Lower cortisol levels may support clearer skin in some people.Relaxing in a steam bath provides not just calm for the mind, but a chance for your skin to reset too. The Cons: When a Steam Room Can Worsen Breakouts For some, steam does more harm than good—especially if your skincare routine slips. The "Pore Opening" Myth: What Really Happens to Your Pores Contrary to popular belief, pores don’t actually “open” or “close”.Steam softens the surface of your skin, making it easier to clear out debris.But if your skin is dirty going in, that heat could just drive impurities deeper. The Overheating Effect: Why Excess Heat Can Inflame Acne Too much heat can lead to inflammation.This may trigger oil production, aggravate acne, and even make blemishes worse.People with active breakouts should limit their time inside or avoid high heat altogether. A Comedogenic Cocktail: The Problem with Sweat and Impurities If you enter a steam room wearing makeup or SPF, you risk creating a pore-clogging mixture.The sweat combines with dirt, oil, and products—creating a layer that clings to your skin.This is one of the most common causes of steam room breakouts. Triggering Specific Conditions: Rosacea and Melasma Certain skin conditions don’t pair well with steam.Rosacea can flare up due to the heat and humidity, while melasma may darken.If you have either, it’s best to check with a dermatologist before stepping in. A Clear-Skin Protocol: Making Steam Rooms Work for You Steam can still be part of your skincare routine—it just needs structure. Pre-Steam Preparation: The Importance of a Clean Face Always cleanse your skin before entering.Remove any makeup, SPF, or dirt to prevent it mixing with sweat.This gives your pores the best chance to purge without trapping grime. During the Session: Hydrate and Limit Your Time Bring water and sip throughout your session.Stick to around 10–15 minutes max—any longer and you risk overheating or irritation.This helps you get the benefits without pushing your skin too far. The Critical "Golden Window": What to Do Immediately After This is the moment your skin is soft, warm, and most absorbent.Gently rinse your face with lukewarm water to remove sweat and any remaining debris.Follow with a light moisturiser or calming serum to lock in hydration. Skincare to Avoid: Spotting Problematic Ingredients Skip products with heavy oils, artificial fragrance, or drying alcohols.These can irritate freshly steamed skin or clog the pores again.Stick with calming, non-comedogenic products to avoid undoing your good work. Takeaways Can steam room cause spots? Yes—especially when used without proper skincare steps. Heat and sweat can clog pores if makeup or dirt are left on the skin. Limit session time, hydrate, and cleanse before and after. People with rosacea or melasma should use steam rooms with caution. A few simple habits can make steam a safe part of your routine. Conclusion Steam rooms can give your skin that post-yoga glow—or trigger a breakout if you're not careful.When done right, they offer skin-cleansing, stress-reducing benefits.But skip the prep, and you might end up with unwanted spots instead. So next time you hit the steam bath, treat it like a mini facial—clean in, calm out, glow on.

Can a Steam Room Cause a UTI?

Ever left a Steam Room feeling amazing—then panicked, wondering if that blissful Steam bath could give you a UTI? Short answer: Not directly, but poor hygiene can raise the risk. Steam rooms themselves don’t cause urinary tract infections. If you’re wondering whether it’s still safe to enjoy your steam sessions, don’t worry.Keep reading for the facts and easy ways to stay protected. Understanding the Connection: How a Warm, Moist Environment Can Increase UTI Risk The Role of Bacteria in Urinary Tract Infections The primary culprit: E. coli bacteria. Most urinary tract infections (UTIs) are caused by Escherichia coli, or E. coli for short.This type of bacteria is normally found in the gut but becomes a problem when it enters the urinary tract. How bacteria enter the urinary tract. Bacteria can make their way from the surrounding skin into the urethra, then travel to the bladder.In places like steam rooms, shared surfaces and moisture may contribute to this. Why Steam Rooms and Other Warm Environments are a Concern The warm, moist environment as an ideal breeding ground for germs. Steam rooms are designed to be hot and humid.Unfortunately, these conditions are also ideal for bacterial growth—especially on unclean surfaces. The risks of shared public spaces and lingering bacteria. Benches, floors, and other high-contact areas may carry bacteria from previous users.If not cleaned properly, germs can remain and transfer easily. The link to similar environments: Comparing steam rooms to hot tubs and baths. Steam rooms share many traits with hot tubs and public baths.They involve damp, warm spaces and shared surfaces, where bacteria can survive.The risks are similar—particularly when personal hygiene is neglected. Additional Factors that Compound the Risk Wearing a wet swimsuit for a prolonged period. Sitting in damp swimwear keeps warmth and moisture close to the body.This creates a perfect setting for bacteria to thrive near sensitive areas. Dehydration and its effect on bladder function. When you don’t drink enough water, you urinate less frequently.This gives bacteria more time to multiply in the bladder and increases infection risk. Practical Prevention: How to Reduce Your Risk When Using a Steam Room Before You Enter the Steam Room Shower beforehand for good personal hygiene. Rinsing off helps remove sweat, dirt, and bacteria from the skin.It also reduces what you bring into the steam room with you. Stay well-hydrated to help flush out bacteria. Drinking water before your session helps your kidneys and urinary system work effectively.A well-hydrated body is better at flushing out harmful bacteria. During Your Session Limit your time to avoid dehydration. Too much time in the heat can cause your body to lose fluid.Try to keep sessions under 20 minutes and take breaks if needed. Use a towel to create a barrier between you and the bench. Sitting on a towel reduces direct contact with shared surfaces.It’s a small but important step for hygiene and comfort. After Your Visit Urinate immediately after your session to flush your urethra. Going to the toilet after steaming helps clear any bacteria that may have entered the area.It’s a simple way to protect against infection. Change out of your wet swimsuit into dry clothes as soon as possible. Staying in damp clothing creates a perfect spot for germs to grow.Dry off quickly and wear breathable fabric to reduce the risk. Drink more water to continue flushing your system. Hydration doesn’t stop after the steam room.Keep sipping water to help your body stay balanced and clear out any lingering bacteria. When to See a Doctor Common Symptoms of a UTI Pain or burning during urination. A burning sensation while peeing is one of the most noticeable signs.It may also come with discomfort or pressure in the lower abdomen. Frequent and urgent need to urinate. You may feel like you need to wee constantly—even if you’ve just gone.Only small amounts may come out, and the urge can be intense. Signs of a More Serious Infection Back or side pain, fever, chills, or nausea, which could indicate a kidney infection. If the infection travels to the kidneys, symptoms can become more severe.Pain in your back or sides, fever, chills, or feeling sick should be taken seriously.Seek medical attention quickly if these occur. The Importance of Antibiotics The role of a doctor in diagnosing and prescribing treatment. UTIs usually require antibiotics to clear the infection fully.Don’t try to self-treat—only a GP can confirm what’s going on and recommend the right medication.Delaying treatment can lead to complications. Takeaways Can steam room cause UTI? Not directly—but poor hygiene and shared, moist surfaces can increase risk. Bacteria like E. coli thrive in warm, damp spaces. Sitting in wet swimwear and dehydration also raise your chances of getting an infection. Good hygiene, hydration, and post-steam habits can keep you safe. Know the signs of a UTI and speak to a doctor if needed. You can still enjoy a Steam Room or Steam bath—just steam smart!
