Sounds silly doesn't it, take time to breathe today, after all we are all breathing all the time... But if you will just stop what you are doing, just for a minute or two, and give yourself some time alone - and focus on your breath, breath in and breath out... you will start to feel the benefit of relaxation. Let your thoughts drift, simply bring your awareness to your breath in and then your breath out, then keep focussed only on your breath for a minute or two, or 20 if you can.
If there is somewhere in nature you love to go to - picture this place in your mind, or have an image of nature you like to gaze at, and bring your awareness to your breath.
