Cryotherapy, simply put, is to help relieve pain, accelerate recovery, and soothe emotions through exposure to extremely cold environments (local or systemic).
The cold baths and cold compresses we are familiar with are actually basic cold therapies in disguise. In the broad sense, cold therapy refers to whole body cold therapy (WBC) and local cold therapy (LBC), which are produced with the blessing of current technology. Usually the temperature can be as low as -110℃ to -140℃. The use of whole body cold therapy is usually controlled within 3 minutes, and the use of local cold therapy is usually within 15 minutes. It will vary depending on the disease.
What exactly can cold therapy bring us?
Accelerate exercise recovery
After strenuous exercise, micro-damage occurs in muscle fibers, and the accompanying inflammatory response can lead to soreness, stiffness and fatigue. Cold therapy can effectively relieve inflammation, reduce swelling and pain by rapidly constricting blood vessels, reducing anti-inflammatory factors and reducing tissue fluid leakage. At the same time, the low-temperature environment can also activate the metabolic pathways of glucose and fatty acids, improve the body's metabolic efficiency, help the body remove metabolic waste faster, and repair damaged muscles.
Relieve chronic pain and discomfort
For people who suffer from joint soreness, stiff back, shoulder and neck tension, etc., cold therapy is a gentle but highly effective physical intervention therapy. By acting on surface and deep tissues at low temperature, it can reduce the sensitivity of nerve endings and slow down the conduction of pain signals. At the same time, cold therapy can also effectively inhibit local inflammatory reactions, reduce swelling and tissue pressure, thereby achieving sustained relief of chronic pain and helping the body gradually return to a light and comfortable state.
Improve mental state and sleep quality
During cold therapy, the body responds to extreme cold stimulation by activating the sympathetic nervous system and rapidly releasing endorphins and norepinephrine. This process not only brings a short-term 'lightness', but also stabilizes mood and reduces anxiety. At the same time, the natural 'fallback' after the overactive sympathetic nerves will also cause the parasympathetic nerves to take over, which will help calm the body and mind and create a good foundation for high-quality sleep.
Burn fat and boost metabolism
Short-term exposure to extremely low temperatures can activate brown adipose tissue (BAT) in the body, promote heat burning and enhance basal metabolic rate, bringing a 'passive fat burning' effect to the body. At the same time, cold therapy can also stimulate the release of anti-inflammatory factors such as interleukin-6 (IL-6), improve glucose metabolism efficiency, and reduce insulin resistance. This mechanism has positive significance for regulating blood sugar levels and preventing type 2 diabetes, and is especially suitable as an auxiliary intervention for people with metabolic abnormalities.
From Kim Kardashian and Paris Hilton to top NBA stars, many people use cold therapy to stay in top physical condition, restart their energy, and find their true self. Nowadays, it has gradually entered the public eye and has become a cutting-edge method that combines sports recovery, daily maintenance and emotional regulation.
Cold therapy can be a powerful assistant in repairing your body and improving your condition, but for special groups such as pregnant women, severe cardiovascular disease, high blood pressure, and specific skin diseases, it still needs to be used with caution after professional evaluation. Safety always comes first.
