Heat sensor pill
I've been reading about these heat sensor pills that runners use to monitor their core temperatures every couple of miles or so.
Any information anyone would like to share regarding their use will be greatly appreciated.
For those of you like myself who have never used these pills, there's an interesting article by Lisa Schnirring entitled, "Core Temperature Measurement Goes High Tech: Pill Sensor Enables Wireless Monitoring," The Physician and Sportsmedicine, Vol. 32, No. 7, July 2004. Go to:
Apparently a company called HQ, Inc. acquired the patent and licensing right from NASA in the mid 1980s to market the pill, but it's not new technology. The cost is high: $2,500 for the handheld monitor and $40 per pill. Hmmmm....a rectal thermometer costs a few bucks.
Also, according to William O. Roberts, MD, a family physician/President of the American College of Sports Medicine, "...it only works if it stays in, which is a problem with some runners who have active GI tracts."
