Understand the biological benefits of contrast therapy. Learn how hot and cold cycles improve circulation, lower inflammation, and reset your nervous system.

## The biological benefits of contrast therapy The practice of moving between extreme heat and cold is a staple in Korean culture, but the reasons behind it are purely biological. When you sit in a sauna or a hot room, your blood vessels expand and your heart rate increases to move blood throughout your system. Switching immediately to cold water creates a physical shock that forces those same vessels to tighten, pushing blood back toward your internal organs and flushing out inflammation. This cycle acts as a workout for your circulatory system. By forcing your body to adapt to rapid temperature changes, you are training your nervous system to handle stress more efficiently and reset your baseline energy levels. What you can expect from this practice:
* Improved blood flow and faster muscle recovery after exercise.
* A natural release of norepinephrine to sharpen focus and mood.
* Reduced systemic inflammation and physical swelling.
* A more resilient response to daily mental stress. Incorporating these benefits of contrast therapy into your routine does not require a professional spa. You can start seeing results by ending your daily shower with 30 seconds of cold water to trigger these physiological changes and improve your circulation.
