About Javier

Most people who tell me they sleep badly sleep a normal number of hours. What they lack is recovery, and you can see it in overnight heart rate variability long before you feel it.

At Kerno I lead the hormonal and sleep blocks. I read the overnight data and the hormone panels, and I decide when a sleep complaint needs a study in a lab rather than a ring at home.

My list is full. I take new members when someone leaves.
