Mindfulness Blue, staying in the now and only right now...each second. It is an ecellent way to not become stressed, anxious, depressed or otherwise. It can also include the breathing which is excellent. More oxygen and blood flow, and bringing your attention to now is no wonder why it works. And we do forget about the breath because we don't have to think about breathing or pay it attention, which is natural but it is so important. I have learned to check in on the breath especially when I start feeling stressed and see what it is up to, usually it is also going a little haywire, same as the mind..where is it? What is it gettong up to? And where do I want it? It can really help to make a practise of just checking in to see what these two are doing.

What I found most helpful was learning to use mindfulness all the the not just when I was having stress or just during a time of meditation. If you keep practicing being mindful throught the day it becomes a new way of approaching life.

I hope that might help..if you want Jon Kabat Zinn has really good videos on youtube that can help a lot. Its something we can do anytime.

With the breath too it is helpful to just sit or lay comfortably and just drop in on the breathing. Focus on the in and out breath and the feeling of the chest rising wnd falling but without manipulating or controlling the breathing. Just paying attention, your body does the rest. Try that for five min, when you mind wanders off just bring it back to the breath. It's very calming and bring your focus to the each moment.

There are so many good breathing exersices..pranayama if you google that you will find a lot of helpful exersices to try and see what works for you.

Another one is makeing each breath slower..so inhale and exhale 3 seconds, next breath 4 seconds, 5 seconds etc. That is a good way to bring the breath back to a relaxed state if you notice the breath is too fast.

I hope you find some ways that help to relieve your stress.
