You may have some problems with your cervical spine because you have been sewing clothes with your head down for a long time. You are still young, so you should cherish and protect your body in the high-intensity production rhythm. You can get up once an hour, go to the toilet or walk around the corridor to create more opportunities for yourself to move around. Bend your head and neck back for more than 15 minutes and do some stretching and chest expansion exercises, which can promote the smooth blood supply to your brain. Sleeping at night without a pillow and replacing it with a cylindrical bean pillow with a diameter of 15 cm can also alleviate cervical problems. If none of these methods can relax you, you can change your post and go to the packaging workshop.
