If you’re involved in a rear end collision, the position of your headrest can play an important role in how your spine is affected.
At impact, the seat you’re in translates forward. This movement shifts the head backwards, stretching the neck. If your headrest is positioned too low, the head and neck will extend back significantly, which increases the forces applied to your cervical spine.
To properly position your headrest, elevate it to the point that it matches the top of your head.
It’s ideal to place the least amount of distance between the back of your head and the front of the headrest, so you may also have to shift the angle of your seat to a more upright position.
If you can reduce or eliminate the distance that your head travels during a rear-end collision, you can mitigate the damage caused by these types of accidents.
