Hot Flashes
Sudden feelings of cold chills or hot flashes can be a typical physical sign of panic disorder and panic attacks. When an episode starts, you might start trembling or sweating excessively. Also, the body of many people would become very cold or very hot, depending on the bouts. These conditions are triggered when the production of adrenaline in the body is increased. Fortunately, they tend to disappear quickly in a couple of minutes. There might be not so severe complications, such as fainting. However, it can be hard for some people to realize a panic attack based on this symptom because it often occurs in many other medical conditions. [3]
