inhale. Keep your back to the wind ; it helps protect your eyes

to lighten your load. In the daytime always wear a woolen 
cloth around your abdomen to prevent chills, especially when

Chilling of the abdomen may bring on diarrhea and other 
complaints.

move helps create a little breeze which aids in evaporation
