Essential tremor is a nervous system condition, also known as a neurological condition, that causes involuntary and rhythmic shaking. It can affect almost any part of the body, but the trembling occurs most often in the hands, especially when doing simple tasks, such as drinking from a glass or tying shoelaces. #yoga #yogaforbeginners #tremor #handtreatment #handstrength #handexercises #parkinsonsexercise
