What is nighttime erection tracking?
Nighttime erection tracking is the measurement of erections that happen during sleep, without arousal. The TechRing Night Guide uses the term for what the FirmTech TechRing does at home: count each nighttime erection and record its strength and length, then show the trend in an app.
FirmTech explains why that matters: an erection needs blood vessels, hormones and nerves to work together, and nighttime erections happen with no arousal involved, so they are a pure read of the body. FirmTech also notes that penile arteries are smaller than the arteries of the heart, so circulation changes often show up there first. Until recently, measuring them meant a sleep lab. The TechRing brings that measurement home and adds performance support during sex.
