Headwinds put me inside of myself. 95% of the time in Summer, I ride home into a hot Southwesterly headwind from 12 to 25 mph.

I get in the drops and focus on cadence and breathing - usually I can make myself disregard it for stretches of time.

I also found it helps to never, ever complain about it, or even bring the subject up in conversation. Somehow that helps me notice it less when I'm on the bike.
