What Do Boxers Sniff Before A Fight

What are nasal sprays and oils used in Roc films? 3

I watched the movie Rock (1976). While Apollo and Rock are preparing for the match in their locker room, the film shows Apollo with a nose-to-nose spray, so they deal with Roc for a nose-to-nose spray. Then they anointed Apollo's arms and legs with oil, then Rocs anointed his arms and legs with oil. What are nasal sprays and oils used for? Is there a good reason for them to do so? Are all boxers suitable or just for movies?

Thank you very much!

Nasal sprays are used to open the sinuses so that you get more oxygen and oil, so when you are wearing gloves, the opponent hits you and the force does not fall directly on you.

Nasal sprays help reduce inflammation. Frequent blowing of the nose can cause swelling. The spray helps control the swelling. As far as oil is concerned, it prevents the opposition from giving it direction and position. It also protects the skin from cracking. That's why you can see fighters spraying Vaseline on their faces. Its appearance will break down the oil on the skin, preventing it from burning. After all, it protects the skin.
