Increases in skin blood flow and sweating are the primary heat dissipation mechanisms in humans. One of the hardest things Brittany has dealt with is comparing . Autonomic dysfunction involving the genitourinary, gastrointestinal, cardiovascular, and thermoregulatory systems is commonly observed in MS (29). Exercising in a pool that is <85 degrees is another option to improve exercise tolerance. Her stories inspire others to live better and staymore, Why MS patients overheat and are sensitive to cold, Living with multiple sclerosis and rheumatoid Arthritis, Lisa Emrich is an award-winning, passionate patient advocate, health writer, classical musician, and backroad cyclist. Spasticity is a common symptom in MS, described as tightness, stiffness, or involuntary muscle spasms, according the National Multiple Sclerosis Society. However, Wilhelm Uhthoff's description of this phenomenon occurring after a hot bath or with exercise in MS patients with a history of optic neuritis has most commonly been cited as the landmark observation of the pathophysiological principle of temperature-induced conduction block in demyelinated axonal segments (Uhthoff's phenomenon) (77). This can lead to a wide range of symptoms throughout the body. MS lesions can also occur in areas of the brain responsible for the control and regulation of body temperature and thermoregulatory effector responses, resulting in impaired neural control of sudomotor pathways or neural-induced changes in eccrine sweat glands, as evidenced by observations of reduced sweating responses in MS patients. People living with MS can be extremely heat sensitive.
