1. Laying: Open the yoga mat completely and lay it flat on the ground or plane, so that the mat has enough space to spread out and put it in a well-ventilated place.
2. Waiting for recovery: Creases usually take some time to recover. 1-2 days later, you should see that the creases are reduced. If the crease is deep, it may take longer.
3. Gently massage: Gently massage the creases with your fingers to help speed up the recovery process.
4. Avoid high temperature and direct sunlight: Avoid exposing the yoga mat to high temperature and direct sunlight, as this may make the wrinkles more obvious.
If none of the above methods can improve the crease, or the crease has affected the use of the mat, you can contact the manufacturer or seller of hatha yoga mat to see if you can provide maintenance or replacement services.
