    The Science

    Cold therapy reduces pain by desensitizing nerves and reducing swelling.

    Inflammation occurs at specific sites within the body, for example an injury, or can be systemic. Cold therapy reduces localized inflammation from exerciseand injuries by reducing edema. Systemic inflammation is usually identified through blood samples and identification of specific hormone markers. Cold therapy reduces systemic inflammation through changes in hormones due to stimulation of the Vagus nerve complex. 

    Cold therapy can help alleviate depression and anxiety. Research indicates that people with depressive symptoms typically have inflammatory markers and cold therapy significantly improves both the systemic inflammation and depression and anxiety symptoms. Cold therapy is a non-pharmaceutical supporting therapy.

    Cold therapy activates hormonal responses in healthy people as well those suffering from chronic diseases such as depression, fibromyalgia, and rheumatoid arthritis. This reduces whole-body inflammation and has antioxidant effects.

    Heart Rate Variability is an indicator of physical and psychological stress. Cold therapy reduces stress and improves exercise recovery times as shown by improved heart rate variability.

    Cold therapy initiates vasoconstriction of blood vessels in the skin and extremities, which aids in reducing muscle pain, fatigue, and swelling. Cold therapy initiated vasoconstriction may be a preventative measure against dementia including Alzheimer’s Disease.

    Top insights

    Research journals on cold therapy

    Autoimmune disorders such as rheumatoid arthritis and fibromyalgia are inflammatory responses. Cold therapy has been proven to provide non-pharmaceutical relief to symptoms. Whole-body cold therapy provides short-term pain relief allowing for chronic pain management and treatment.

    Additional studies by Lange et al also showed tha tinflammatory markers such as TNF-alpha and IL-1 are significantly reduced with cold therapy, indicating a long-term effect.

    There is strong evidence of improvement for psychological factors such as depression and mood disorders with whole-body cold therapy with effects lasting at least two weeks after the final session.

    Intensive physical exertion (exercise) results in fatigue, muscle damage, and edema. Cold water immersion therapy reduces pain, fatigue, and edema for 90-96 hours after treatment.

    Stress in the form of physical exertion (exercise) as well as life stress trigger similar hormonal responses that affect heart rate and heart rate variability. Cold water immersion therapy stimulates the Vagus nerve, which in turn lowers the subject’s heart rate and improves heart rate variability. These reduce stress and induce relaxation.

    Dementia including Alzheimer’s disease is believed to be an inflammatory response with impairment of the vascular system and oxidative stress on the brain. Similar to the short-term benefits to athletes for vasoconstriction and reduction of inflammation and edema, studies indicate that the brain receives similar benefits. Cold water immersion may be a cost effective preventative measure for development of dementia before symptoms develop.
