Hello Friend, there are some common stress management techniques like self bahaviour therapy, yoga, meditation, exercise, learning hobbies, change of dietary (reducing spicy foods), break out from job, avoid caffeine, few lifestyle changes etc. However it better to take a professional counselling support to assess your current level of stress to identify the root cause for your stress and suitable solutions that you can follow practically. Don't hesitate to consult.

Solutions vary from person to person. It is actually customized according to the issues related to that person. I suggest you to consult a psychologist personally in your city.
