Is it healthy to jump in cold water?
Better circulation. ‘When we jump into cold water, the extreme change in temperature signals to our heart to pump more blood to our organs,’ says McCormick. ‘As a result, circulation is improved, and toxins are more readily flushed out of our system, which leads to clearer skin and a healthy glow.

| Short-term | After 3 minutes | Superficial neuromuscular cooling |
What does a cold plunge do for your body?
