Does cycling without stretching make you shorter? My brother said recently:


  You need to stretch after you cycle or you will become shorter.


I am very sceptical about this and a simple Google search doesn't bring up anything in the affirmative.

My question is, is it true that cycling without stretching afterwards is linked to height loss?
Everyone gets shorter during the day as the spine compresses under the influence of gravity.  This is then reversed as you sleep at night.  Yoga and stretching that improve core strength and posture can counter this effect.  However it is not clear that cycling will make the effect any worse - in fact the extra exercise may actually help!
