If you’ve been scrolling through social media lately, you’ve probably noticed your favorite wellness influencers taking icy plunges into freezing waters or standing in cryotherapy chambers. It’s all part of a trending practice called cold exposure therapy, and it’s gaining serious traction in the mental health and wellness space.
Let’s dive into (pun intended) what cold exposure therapy is, why it’s trending, and whether science backs up its claims of mental clarity and improved emotional well-being.
What Is Cold Exposure Therapy?
At its core, cold exposure therapy involves intentionally subjecting your body to cold temperatures for a short period of time. This can include:
- Cold showers
- Ice baths
- Cryotherapy (standing in a chamber cooled to subzero temperatures)
- Winter swims in natural bodies of water
The idea isn’t new—many cultures, from Scandinavian countries with their sauna-to-cold-dip traditions to ancient practices in Japan, have embraced the health benefits of cold exposure for centuries.
The Link Between Cold Exposure Therapy and Mental Clarity
Advocates of cold exposure therapy often claim it can boost mental clarity, reduce stress, and even enhance emotional resilience. But how does being uncomfortably cold help your brain?
- Endorphin Release
Exposure to cold triggers a rush of endorphins—your body’s natural feel-good chemicals. This is often referred to as the “cold high,” and it can leave you feeling euphoric, clear-headed, and motivated. - Stress Adaptation
Cold exposure activates the body’s fight-or-flight response. Over time, this can train your nervous system to handle stress more efficiently. A study published in Medical Hypotheses found that regular cold exposure may reduce stress-related inflammation, which is linked to mental health disorders like anxiety and depression. - Improved Focus Through Dopamine
A fascinating study shared by Dr. Andrew Huberman, a neuroscientist at Stanford, reveals that exposure to cold water can increase dopamine levels by up to 250%. Dopamine is a key neurotransmitter for focus, motivation, and emotional regulation.
The Physical and Mental Health Connection
It’s no secret that the body and mind are deeply connected. By improving your physical health, you can indirectly support your mental health. Cold exposure therapy may help by:
- Boosting Circulation: The rapid temperature change increases blood flow, delivering oxygen to the brain.
- Reducing Inflammation: Chronic inflammation is a known contributor to mental health issues. Cold exposure can help reduce it.
- Improving Sleep: A quick cold plunge can regulate your circadian rhythm, leading to better sleep quality—a cornerstone of mental wellness.
How to Get Started With Cold Exposure Therapy
If the idea of willingly stepping into an icy environment sends shivers down your spine, don’t worry. It’s all about starting small and working your way up.
- Start With Cold Showers
Begin by ending your usual warm shower with 10-15 seconds of cold water. Gradually increase this time as you get comfortable. - Try an Ice Bath
Once you’ve mastered cold showers, try a 2-3 minute ice bath. Keep the water temperature between 50-59°F (10-15°C). - Experiment With Cryotherapy
Cryotherapy chambers are a great option if you prefer a more controlled environment. Sessions typically last 2-3 minutes and are supervised.
Is Cold Exposure Therapy Safe for Everyone?
While cold exposure therapy has many potential benefits, it’s not for everyone. People with cardiovascular issues, Raynaud’s disease, or other circulatory problems should avoid it or consult their doctor first.
Also, keep in mind that moderation is key. Overdoing it can lead to hypothermia or cold-related injuries. Listen to your body and gradually increase your tolerance.
Does the Science Back It Up?
While anecdotal evidence is strong, the scientific research on cold exposure therapy is still evolving. Early studies are promising, showing potential for improved mental health, reduced stress, and enhanced cognitive function. However, more large-scale studies are needed to confirm these benefits.

Just a Trend?
Cold exposure therapy isn’t just a trending wellness hack—it’s a practice rooted in science and history that may offer profound mental health benefits. Whether you’re looking to boost mental clarity, build resilience, or simply shake up your wellness routine, this icy trend might be worth a try.
