If you’ve ever recoiled at the thought of a cold shower, you’re not alone. For most of us, the idea conjures up images of shivering misery, not the secret to a longer, healthier life.
But what if that bracing blast of cold water each morning could do more than just wake you up? What if it could actually add years to your life, boost your mood, and even help you fight off disease?
Let’s dive into the chilly world of cold showers and see if they really deserve a place in your daily routine.
Why are cold showers suddenly so popular?
From Wim Hof’s ice baths to viral social media challenges, cold water therapy is having a moment. But this isn’t just a passing fad.
The practice of using cold water for health dates back centuries, with everyone from ancient Romans to Scandinavian sauna-goers swearing by its benefits.
Today, science is catching up, and researchers are starting to uncover some fascinating effects of regular cold exposure.
Before you rush to turn your hot tap off, a quick word of caution: if you have any pre-existing health conditions—especially heart problems, circulatory disorders, or arthritis—check with your doctor before making cold showers a habit. Safety first!
The science-backed benefits of cold showers
Let’s be honest: the main downside of a cold shower is, well, the cold. But the upsides? They’re surprisingly impressive.
1. Reducing inflammation and easing aches
Inflammation is at the root of many chronic diseases, from arthritis to heart disease. Cold water causes your blood vessels to constrict, which helps reduce swelling and inflammation.
As your body warms up again, fresh, oxygen-rich blood rushes back to your tissues, helping to flush out toxins and speed up recovery.
That’s why athletes have long used ice baths to bounce back after tough workouts.
2. Boosting your mood and mental health
Feeling a bit flat? A cold shower might be just the pick-me-up you need. Exposure to cold water triggers the release of endorphins—your body’s natural feel-good chemicals—by activating the parasympathetic nervous system.
Some studies even suggest that regular cold showers can help reduce symptoms of depression, with participants reporting improved mood and energy levels after just a few weeks.
And unlike many medications, there are no nasty side effects (apart from a few goosebumps).
3. Improving circulation and heart health
Good circulation is vital for a healthy heart and a long life. When you step into cold water, your body goes into ‘survival mode’, ramping up your circulation to keep your core warm.
Over time, this can make your circulatory system more efficient, potentially helping to lower blood pressure and improve overall cardiovascular health.
For those managing conditions like diabetes or hypertension, this could be a simple way to support your treatment plan.
4. Giving your immune system a boost
Want to fend off winter bugs? Cold showers might help.
Research shows that regular exposure to cold water can increase the production of white blood cells, which are your body’s frontline defenders against germs and illness.
Some studies have even found that people who take cold showers regularly take fewer sick days than those who stick to hot water.
5. Supporting healthy weight loss
Maintaining a healthy weight is a key ingredient in the recipe for longevity. Cold showers (and even colder ice baths) can help by activating ‘brown fat’—a special type of fat that burns calories to generate heat.
Your metabolism gets a temporary boost as your body works to warm itself up, which means you burn more energy even after you’ve towelled off. No wonder you feel so hungry after a swim in the ocean!
6. Glowing skin and hair
If you’re after a more youthful appearance, cold water can help here too. It tightens pores, reduces puffiness, and can even make your hair look shinier and healthier.
While it’s not a miracle cure, it’s a simple addition to your beauty routine that costs nothing.
How to start (without turning into a human icicle)
If the thought of a full cold shower makes you want to run for the doona, don’t worry—you don’t have to go from zero to polar plunge overnight. Here’s how to ease into it:
1. Start warm: Take your usual warm shower, washing as normal.
2. Finish cold: At the end, turn the water to cold (anything under 16°C counts) for 30 seconds. Focus on deep, steady breaths and move around to distribute the water.
3. Build up gradually: Over time, increase the cold blast to two minutes, then up to five if you’re feeling brave.
4. Pick your moment: Some people love the morning jolt, while others prefer the calming effect before bed. Experiment to see what works for you.
Dr Majdoline Jayoushe, an internal medicine specialist, suggests starting slowly and listening to your body.
Remember, you’re most sensitive to cold in the morning when your core temperature is lowest, so don’t be surprised if it feels extra bracing at sunrise!
Are cold showers for everyone?
While most healthy adults can safely enjoy cold showers, they’re not for everyone. If you have heart disease, circulatory issues, or certain joint conditions, check with your GP first.
And if you ever feel dizzy, short of breath, or unwell during a cold shower, stop immediately.
The bottom line: Can cold showers really add years to your life?
There’s no magic bullet for longevity, but cold showers are a simple, free, and surprisingly effective way to support your health.
They can reduce inflammation, boost your mood, improve circulation, strengthen your immune system, and even help you maintain a healthy weight. Combined with a balanced diet, regular exercise, and good sleep, they could be a valuable addition to your daily routine.
