Long Deep Breathing:

• Influences the Parasympathetic Nervous System to Relax and Calm
  
• Stimulates the Brain to produce Endorphins, which reduces or eliminates depression, or keeps depression away
  
• Creates Alertness in the Brain
  
• Pumps Spinal Fluid to the Brain
  
• Regulates the body's pH to help handle stressful situations
  
• Allows physical and emotional healing, or disease prevention
  
• Reduces or Eliminates Pain (like Lamaze breathing during childbirth)

Sit in a chair with your feet flat on the ground and parallel to one another.  If this is your first time doing this, it helps to put one hand on your belly, and the other on your chest to reinforce the feel of your belly, rib cage, and shoulder movements.

Use your timer on your smart phone.  Start with a two minute timer, with four counts on the inhale and four counts on the exhale.  As your breath becomes stronger over time, increase the counts, and increase the time up to five minutes.

You can also do this standing straight, feet parallel, and hip distance apart, with your hands and arms relaxed down on your sides.  

Eyes may be open or closed, but if you have privacy, or are with people doing this together, close your eyes and focus on the point between your eyebrows. 

This is so simple that a doctor could teach this to relieve anxiety, instead of offering Zoloft or Prozac.
