Heat sensitivity

High temperatures make it harder than it already is for demyelinated nerve cells to conduct electrical signals. Because of this, many people with MS may experience a temporary worsening of MS symptoms when exposed to heat or dealing with a fever. Symptoms caused by heat are typically temporary and do not cause further damage to the nerves. Once the temperature cools, even by a small amount, the symptoms usually subside.
