Pain is a common experience for many people, and it can be caused by a variety of factors, including injury, inflammation, and chronic conditions - or even pain and soreness post-workout.

Did you know that the Egyptians were the first known users of cold therapy to treat inflammation? And, interestingly, Hippocrates, considered the father of cryotherapy, referenced the use of snow and ice to combat swelling in his writings. Cold therapy, as a tool for alleviating pain and inflammation, has a long history, yet the biological mechanisms behind how cold exposure reduces pain and swelling still hold some mysteries. Today, I'll shed light on some of these answers.
First, let's clarify some terms that can sometimes cause confusion.
What is Cold Water Therapy?
"Cryotherapy" is a broad term encompassing various cold exposure methods, including cold-water immersion, exposure to cold air in cryochambers, or using ice packs to alleviate symptoms by removing heat, reducing core body temperature, and altering blood flow to the injured area. This, in turn, yields benefits such as reduced perception of pain and improved overall well-being, especially during post-exercise recovery and/or after injury.
Whole-body cryotherapy, developed in Japan in the 1970s, is an extreme cold therapy lasting 1–3 minutes, conducted in a cold room with an air temperature of -110˚C. Widely used in several European countries, it is primarily employed for medical reasons. Winter swimming also falls under the category of whole-body cryotherapy and has been utilized for centuries in Denmark, serving both as a treatment for rheumatic diseases and as a recreational pastime in frozen waters.
Biological Explanations for Pain Relief with Cold Exposure
Cold therapy, renowned for its pain-relieving and anti-inflammatory effects, has been used anecdotally for many years. Hormones frequently studied in relation to whole-body cold exposure include catecholamines: adrenaline, noradrenaline, endogenous opioids (β-endorphins), and the steroid hormone cortisol. Dopamine also plays a significant role in pain relief. β-endorphins, often referred to as our "natural painkillers," are a potent means of reducing pain and enhancing quality of life. However, other hormones and neurotransmitters contribute to the process.
Here's a summary of key hormone-related facts:

Post-Workout Recovery: Noradrenaline and Cold Water Immersion
Unlock the Power: Noradrenaline and Cold Water Immersion Discover the Secret: Easing Joint and Muscle Pain
If you are interested in maximizing your workout recovery, cold water immersion is a fast solution for pain relief. Research shows that noradrenaline levels increase during the initial few minutes when you submerge in cold water, providing a natural remedy for discomfort. By stimulating both noradrenaline and dopamine, cold water can help alleviate joint and muscle pain, facilitating accelerated muscle repair.
Cold Water Immersion for Chronic Pain Management
Both whole-body cryotherapy and cold-water immersion can be employed for managing various types of pain, including acute injuries (such as sprains, strains, and bruises), chronic pain conditions (like arthritis and fibromyalgia), post-surgical pain, headaches, and migraines.
Whether you are seeking cold water immersion for post-workout recovery or seeking relief from chronic pain, cold therapy continues to prove its effectiveness through various biological pathways.
