Introduction: Physical activity performed by patients with multiple sclerosis, alleviates the effects of the disease and helps maintain physical condition. However, the rising of the body temperature due to being physically active can trigger symptom aggravation. Body cooling before or during a physical activity is used as a therapeutic method, which reduces the emergence of newly created symptoms and enables better cooperation of patients. Purpose: The purpose of the dissertation was to make an overview of writings about the effects of cooling on the symptom suppression on patients suffering from multiple sclerosis. Methods: The research papers were found in the corpora of PubMed, Cochrane library and PEDro. Results: There were five research papers integrated into the writings overview, which were published between 2008 and 2020. In these research papers cooperated a various number of patients, namely between ten and 24 with different stages of the disease, mostly with the relapsing-remitting form. A cooled room during a physical activity aids in a higher level of walking speed, a better physical condition, a higher contraction maximum of plantar flexors, a higher quality of life, and lowers the levels of exhaustion. Drinking cool water during training prolongs the period of a physical activity. The cooling of the whole body during training, lowers the heart rate in inactivity and the feeling of exertion. The cooling of the upper limb during a physical activity prolongs the period of training and raises the maximum heart rate. Conclusion: Body cooling during a physical activity is an efficient method to improve walking speed, prolong the period of a physical activity, raise the contraction maximum of muscles, and lower the body core temperature. It also helps lower the levels of exhaustion, feeling of exertion and overall contributes to the higher quality of life of patients with multiple sclerosis. For more reliant results, there needs to be more randomised controlled trials with a higher number of patients.
