1. Physical Health Benefits
a. Reduces inflammation and muscle soreness
• Cold water constricts blood vessels and reduces inflammation in muscles and joints.
• Commonly used by athletes after intense workouts to speed up recovery.
b. Boosts circulation
• When you enter cold water, your body redirects blood to vital organs.
• After exiting, blood vessels dilate, improving overall circulation.
c. May support weight management
• Cold exposure can activate brown fat, a type of fat that burns calories to generate heat.
• This can slightly increase calorie expenditure.
