These are some techniques that I have used to try to stop hand tremors. Some of them have helped me, but fundamentally, I have just had to work out how to do my job with hands that shake.
Exercise – exercising releases chemical mediators called endorphins (not too dissimilar in chemical nature to morphine), which causes the body to naturally rellax and provide natural analgesia for pain. This is why some people can become literally addicted to exercise, because they enjoy the high that they get after exercising. Likewise, some people who are used to regular strenuous exercise, may find that they devellop depression or mood swings as a result of being unable to exercise.
Manage your sleep deprivation. I’m a shift worker, and I understand just how hard it is to get enough sleep. Unfortunately, sleep is like a piggy-bank, if you withdraw too much awake time without replenishing it, you run out, so make sure that if your a becoming sleep deprived, you take steps to have extra sleep later to make up for it. If your sleep piggy-bank is short, it needs re-filling!
Rellax more – this sounds obvious, and easier said than done, but even taking the time to watch a movie, catch up with friends, have a hot bath, or a glass of wine (try to avoid the whole bottle though) all make a big difference in the levels of serotinin (mood stabiliser/natural rellaxant in the body), which reduce the symptoms of hand tremors.
Take up some form or rellaxing activity, such as Tai Chi, Yoga, or Pilates.
