do you think the stress balls really helps to reduce tension???

I have never tried them, but I am sure they do work for some people, but probably not for everyone. Stress and dealing with stress is something pretty individual after all!

What they do is they make some type of distraction so you can focus on something else, but if problem is way more serious then you may need some heavier alternatives, I don't know, just to mention a few, some natural teas to relax, therapy, play sports, read a book without any outside noises, etc.
