A study from 2014 found that people who spent two hours in a mildly cold room (around 19°C or 66°F) burned about 100 to 200 extra calories. That’s nice, but it’s roughly the same as taking a brisk 20-minute walk. Meanwhile, you’re sitting there in a sweater, wondering why your toes are turning blue.
The real hero here isn’t just the cold water—it’s your lifestyle. If you swap your daily ice bath for a healthier diet and a walk around the block, you’ll get far better results. Think of cold water as a supporting actor, not the star of the show.
The Ice Bath vs. Real Life
Meet Sarah, a friend of mine who bought a cold plunge tub for her backyard. She was determined to “burn fat” while binge-watching Netflix. After three weeks, she lost maybe a pound and gained a lot of sympathy from her neighbors. She now uses it to wake up, not to lose weight.
On the other hand, cold water can help in other sneaky ways. Ever notice how a cold drink makes you feel more awake? That’s because your body burns a tiny bit of energy to warm it up. But don’t go chugging ice water after dinner hoping to counteract that slice of cheesecake—it won’t work.

The real benefit of cold exposure is improving your metabolism’s flexibility. When you regularly expose yourself to cold, your body gets better at adapting and burning energy efficiently. It’s like teaching your car to run on different types of fuel—helpful, but not a replacement for an oil change.
