One issue that can develop over time is cervicogenic headache. This issue strains your muscles that span over your head. This origins from bad posture, typically from a screen-based job. Some exercises that help in these area, according to my physical therapist, are bending over your head as much as possible. Hold this position for 10 seconds. Then move your head back, such that you make a double chin. Also hold this for 10 seconds. The more you do these exercises, the better. They should strenghten your neck musculature. This way, you will develop a flexible neck.

There are useful Qi Gong moves for facial muscle rejuvenation (especially around the forehead and around the sinus area) and also to release muscle tension in the neck and shoulders. I like to do Qi Gong while waiting for things to happen in the kitchen. You can find decent videos on YouTube that show you how to do this.

I've been doing these neck mobility exercises, I think they seem to help

I am doing something that is similar. But in my case, I maintain the position for 10 seconds. When bending backwards, I try to maintain my head in the same 'vertical position' (if that makes sense to visualize). My physical therapist described it as making a 'double chin'.
