When it comes to relieving stress, people say, “Take a deep breath.” But a deep EXHALE may be more crucial than a deep INHALE. Physical therapist Dr. Emily Kiberd says most people think deep breathing should be about taking IN more oxygen. But the stress-relieving oxygen doesn’t reach our bloodstream until we breathe OUT. So, try this: Inhale through your nose for a count of 4… Hold it for another 4 seconds… Exhale for 8 seconds. That’s in for 4, hold for 4, exhale for 8. That’ll calm your nervous system, relaxing you.
