I am taller, have a lower desk, and work at a desk for a long time, which causes low back pain, how can I solve it?

Padding the height of the table, lower the height of the chair, look at the computer screen flat or up instead of looking down, and walk around and move after 30 minutes of work. Pay more attention to the functional training of the lumbar area, increase the strength and stability of the core muscles of the lumbar area, and swim more if possible.
