Sending out job applications for the last few weeks and I noticed my neck was aching before I even got out of bed. Most of the applying happens from the couch, laptop on my knees, screen way below eye level, and looking back that’s basically been my posture for about 3 weeks straight.
What actually helped was almost embarrassingly simple. Stacked some old textbooks under the laptop until the screen top was roughly eye height, stuck a rolled up towel behind my lower back so I’m not sinking into the cushions, and started standing up for a minute every time I hit submit on an application instead of tabbing straight to the next one.
Morning stiffness let up after about 5 days of doing that consistently. Still creeps back if I’m gaming late and skip the towel, but nowhere near what it was.
Wasn’t about sitting up straighter through sheer effort, just made the setup do that part for me instead.
