How Many Ice Baths a Weekの基本情報から最新動向までをわかりやすく整理しました。

So, to answer the burning (or rather, freezing) question: three to four ice baths a week is the optimal dosage for most humans. Less than that, and you’re just playing peekaboo with cold water. More than that, and you’re entering a weird, damp obsession that might require a therapist. Listen to your body—if it tells you to stop, get out. If it tells you to keep going, you might be a Viking reincarnated. Either way, don’t forget to warm up afterward with tea and a blanket. You’ve earned it, you little popsicle.
