I can easily hold my breath for well over 45 seconds under normal conditions, but when I stick my face directly into stiff blowing restroom handdryer or a high powered hair dryer, or some other type of powerful fan, I can only hold my breath for 15-20 seconds?
Why is this?
How can I hold my breath for longer lengths of time when I stick my face in the blowdryer?

Has to do with perceptions of air. When you hold your breath normally, air is trapped in your nasal passages, dormant, and doing nothing.
When you blow the air at your face, the air pressure changes in the nasal passages, causing you to feel as if the air is being sucked from your lungs.

It's a psychological thing. You're physically just as able to hold your breath, but your mind isn't letting you.

Your heart rate speeds up because of the increased stimuli, and you to use more oxygen.
