Lauri Leadley

CCSH, RPSGT, President- Clinical Sleep Educator

My fascination with the physiology of sleep began more than 30 years ago when I was a respiratory therapist and saw a patient with sleep apnea for the first time. It led me to become a sleep technologist. I remember my very first patient who woke up after a sleep study and said, “Wow, I’ve never dreamt before and l last night I had dreams!” It was a turning point in my career.
 
Our culture, in general, doesn’t recognize the human body’s need for adequate sleep. I was guilty of this for years. Chronic pain has interrupted my sleep and life for as long as I can remember and I continued to ignore it.
 
It wasn’t until my second cancer diagnosis that I found myself struggling to fall asleep and stay asleep and I knew that the lack of sleep was impacting my body’s ability to heal. I experienced first-hand the results of having a long-running pattern of sleep loss and its effect on my health.
 
My own health challenges over the years fed my desire to change lives. Now I’d like to help you overcome your battles.
