The best antistress medicine we have may be right under your nose! Think you know how to do it? Try this simple test: sit or stand wherever you are and take a deep breath, then let it out. What expanded more as you inhaled, your chest or your belly? If the answer is your chest, you’re like most people and you’re doing it wrong.
Take another deep breath and breathe like a baby. 
Watch a baby breathe and you’ll see the belly go up and down, deep and slow. Slow, deep breathing is probably the single best antistress medicine we have. When you bring air down into the lower part of the lungs, where oxygen exchange is most efficient, everything changes. Heart rate slows, blood pressure decreases, muscles relax, anxiety ceases and the mind calms.
I'm a teacher but sometimes patience is not my virtue. I'm moody but caring, sensitive but thoughtful and generous to a fault.
