recently i got an amazing garmin 405 forerunner watch which has on board gps and a heart rate monitor. it is awesome for running (main purpose) - but once i have a cool device for data collection i tend to play. recently i have been using the device to graph my heart rate while i sleep. the results are totally amazing (see below). friday night i averaged 55 bpm throughout the night and the curve looks really clean -- i remember sleeping well. saturday i went out with friends and perhaps had a bit too much wine.... my average was significantly higher as a % ... i woke up early after just over 5 hours of sleep, but i remember being basically already awake before i got up... sunday, was i stressed? it really looks like i didn't sleep well.
twitter - @doctors, how am i looking? do i need to come in for a checkup or does the below look normal :) -- is this the future of health?
p.s. garmin - i have now bought another 405 for a friend, and convinced at least 3 other people to buy your watches -- that is a few thousand in revenue for you... how about an affiliate kickback :)
