I've never had a problem with peripheral vision.
Aslo, you'll be so overloaded with what's going on in front of you, the instructor yelling at you telling what you're doing wrong, you'll never notice wether your head is getting hot or not!

Gona build myself a castle, High up in the clouds.
There'll be skies outside my window,
Lose these streets and crowds.
Will find myself an ocean, Sail into the blue.
Live with golden swordfish, Forget the time of you.
Dance myself to nothing, Vanish from this place.
Gonna turn myself to shadow, So I can't see your face.
Dance the night away.
