When it comes to neck and back pain, you can be your worst enemy.
People tend to get into bad habits all the time and their bodies suffer for it.
Do you rest against the back of the seat or do you lean forward? Do you let your head rest against the headrest? Are your arms reaching far to steer the steering in an uncomfortable position?
These are some things that can make a difference of either being in pain or not being in pain. Now, what can you do?
Adjust the seat a little closer rather than further away will allow you use the back of the seat and the headrest. This will also reduce the reaching distance to the steering wheel. This also helps if your hamstrings are tight by allowing the knees to bend a little more. If your seat doesn't support your lower back by keeping it arched, try adding a small pillow to support it. This is one simple way to put your back into a more relaxed position.
