some gyms put a fragrance device in their ventilation system to keep the place from smelling like sweaty ass)
Hello,Wear a headband. Also, carry a towel with you everywhere and wipe at least three times per minute. And, you need to make sure that your towel and headband match both each other and your outfit. Additionally, always breath through your mouth if at all possible so as to avoid overworking your nasal region. Finally, avoid sweating at all costs so as to reduce itching and most other exercise-related discomfort.
Hope this helps!
