More doctors are now prescribing it almost as a medication to help with healing and more.
Tiffany Bullard is in full nesting mode. The 31-year-old costume designer and her director husband are about to welcome their first child, but it's been a difficult journey. Bullard miscarried twice.
Unsure of where she was mentally and physically she turned to meditation.
"I thought maybe this is what I need to get back on track so I can heal," she said.
She took a class at Northwestern Integrative Medicine, where doctors work meditation into their clinical care to alleviate physical and emotional symptoms.
Its gaining respect in the medical community as more research reveals this practice of calming the mind and focusing isn't just an exercise in self-indulgence. It can actually bring real changes to the brain.
"The use of meditation is based on hard-nosed science," said Dr. Melinda Ring, internist, Northwestern Integration Medicine. "It is amazing the capacity of our brain this organ has for change."
These changes seem to promote higher levels of well-being and resilience.
