If the ring is in close contact with the finger, it will cover up the evaporation of sweat secreted by the sweat glands of the finger, and the sweat will stink if it stays on the finger for a long time. Human sweat contains urea, so it stinks.

This is similar to the principle of foot odor. The solution is simple.

Take off the ring, wash your fingers with soap, and wipe the inner ring with a wet soft cloth dipped in detergent to ensure that it doesn't stink!

In addition, according to your situation, sweat glands are developed, remember to wash your hands and clean your ring often!
