The 7 Benefits of a Cold Shower, According to Experts
For many, the idea of stepping into a cold shower first thing in the morning sounds like a nightmare. However, science and wellness experts suggest that embracing the chill could come with surprising health benefits. From boosting circulation to improving mood, here are seven reasons to consider turning that temperature dial down.
1. Improves Circulation
One of the most well-known benefits of cold showers is their impact on blood flow. When exposed to cold water, the body works harder to maintain its core temperature. This process constricts surface blood vessels and increases circulation in deeper tissues. Dr. Christopher Minson, a human physiology professor at the University of Oregon, explains that this can promote better cardiovascular health over time.
2. Boosts Mood and Mental Clarity
Cold showers are known to stimulate the release of endorphins—feel-good chemicals in the brain. According to Dr. Nikolai Shevchuk, who studied cold exposure therapy, a cold shower can act as a mild form of electroshock therapy, sending electrical impulses to the brain and resulting in an anti-depressive effect. The shock of cold water can also increase alertness and mental clarity, making it a powerful morning pick-me-up.
3. Enhances Immunity
Cold exposure may strengthen the immune system. Research published in the journal PLOS ONE found that people who took cold showers for at least 30 seconds reported fewer sick days. Experts believe this is due to an increase in white blood cell count, which helps the body fight off illness.
4. Reduces Muscle Soreness and Speeds Recovery
Athletes have long used ice baths to reduce inflammation and speed up recovery after intense workouts. A cold shower can offer a similar, albeit less intense, benefit. Cold water can help reduce muscle soreness and fatigue by lowering tissue temperature and decreasing inflammation, according to Dr. Stacy Sims, an exercise physiologist.
5. Improves Skin and Hair Health
Hot showers can strip the skin of natural oils, leaving it dry and irritated. Cold water, on the other hand, helps tighten pores and cuticles, reducing the likelihood of clogged pores and acne. It also helps hair retain moisture and appear shinier and healthier, says dermatologist Dr. Whitney Bowe.
6. Supports Weight Loss
Cold exposure may activate brown fat—a type of fat that burns calories to generate heat. A study published in the Journal of Clinical Investigation found that cold exposure increases metabolic rate, potentially supporting weight loss efforts when combined with a healthy lifestyle.
7. Builds Mental Resilience
Taking a cold shower is not just a physical challenge—it’s a mental one. Regular exposure to discomfort can help build mental toughness and stress tolerance. “It’s a small, controlled way to teach your body and mind how to handle stress,” says wellness coach Dr. Sarah Ballantyne.
Final Thoughts
While cold showers aren’t a cure-all, experts agree they offer a range of physical and mental health benefits. If you’re new to cold exposure, start slowly—try ending your regular warm shower with 30 seconds of cold water and gradually increase the time. Your body—and mind—might thank you.
