In brief: Many reasons
Hormonal-low thyroid makes you cold and shivering generates heat, low blood sugar causes adrenaline to be released; neurologic-pinched nerves cut connections betn brain and spinal releasing control of muscles, damage to parts of brain eg parkinsons; anxiety causing excess adrenaline, drugs like caffeine, stimulants mimic adrenaline.
