I guess cycling gloves can cut off circulation and exacerbate hand tingling and numbness. I have always had some bother with it on long bike and motorcycle rides. I found an on bike stretch that helps to relieve it. Kind of hard to describe but take one hand at a time and bend the wrist and place the base of your thumb into your solar plexus. It's like a monk's prayer (and it may even be called that). Hold it for 15-20 seconds in front of you then do the reverse behind your back for another 15-20 seconds, but flip your wrist first. Repeat with your other hand. Your fingers should be point upwards in both positions.
