Routine helmet users reported higher experienced risk and cycled slower when they did not wear their helmet in the experiment than when they did wear their helmet, although there was no corresponding change in HRV. For cyclists not accustomed to helmets, there were no changes in speed, perceived risk, or any other measures when cycling with versus without a helmet. The findings are consistent with the notion that those who use helmets routinely perceive reduced risk when wearing a helmet, and compensate by cycling faster. They thus give some support to those urging caution in the use of helmet laws.
When I switched to off-road riding exclusively I started wearing a helmet full-time, because I suck at off-road riding. I've been doing it for a few months now so don't suck quite as much, and started leaving the helmet at home on occasion. I've noticed that I fall off less without it. When I'm wearing it I "take my chances" even though I don't consciously feel safer with it on. When I'm not wearing it I get off and walk the "riskier" sections. I'm pretty sure that's the whole concept behind the "risk compensation" deal. I honestly don't know if my head is any safer with or without the helmet, but the rest of me definitely stays in better shape when I go bare-headed.
