Ice baths are everywhere in modern fitness culture. From professional athletes to weekend warriors, many swear by the post-workout plunge, hoping the icy shock will ease soreness, calm inflammation and help their bodies bounce back faster. But recent research from the Netherlands reveals a surprising downside: those freezing dips might actually slow muscle growth.
When you expose your body to cold, like during an ice bath, your blood vessels constrict. This can reduce swelling, flush out waste products from your workout and ease the muscle soreness that occurs a day or two after intense exercise. That post-workout ache is a sign that your muscles are repairing. So when it fades, it feels like you’re ready to hit the gym again, which helps explain why ice baths are so popular.
