Because meditation can increase both emotional and physical sensitivity, McLean said it's important to "take care of the integration period after a mediation practice.  You don't want to come out too quickly.  It's like jumping out of bed when the alarm goes off."

According to McLean, it's best to meditate in the morning or early in the evening, ideally on an empty stomach.  Attention, a focus for that attention and willingness are the three most important factors to start meditating, she said.

During meditation, focus on breathing.  Whenever a random thought passes, keep redirecting the attention back to your breath, Mclean directed.

"You're training your brain not to be reactive to the external world or the ideas you have," McLean said.

McLean stressed meditation takes work to achieve.  "That's why it's called a practice," she said.
