Most people spend a large part of their day looking down. Phones, tablets, and laptops pull the head forward and hold it there, often for long stretches without a break. After a car crash, that habit can be hard to judge, because you may not notice how often you do it until your neck starts to complain. A simple screen log gives you something concrete to bring to an examiner, and it costs nothing but a notebook or a note on your phone.
Start the log on the day you can manage it, even if you feel only partly back to normal. Each day, write down the approximate number of hours you spent looking at a phone, a tablet, a laptop, or a monitor. Estimates are fine. Round to the nearest half hour and be honest about the total, including scrolling in bed or watching videos on the couch. Note the setting too, such as at a desk, on the sofa, in bed, or in the car as a passenger.
What to Record Besides Hours
Hours alone do not tell the whole story. Add a few short notes to each day. Write down whether you held the device low in your lap, at chest height, or up near eye level. Note whether the screen felt too small, too bright, or too far away. If you use a laptop, record whether you typed on a surface at about elbow height or on a bed or cushion where your arms and head drifted.
Also track what happened afterward. Did your neck feel tighter within an hour? Did a headache, a tired jaw, or pain between the shoulder blades follow a long session? Did a break, a stretch, or a change in position help, and how quickly? Write these down in plain words, such as "neck ache started about 40 minutes in" or "upper back eased after I stood up." Specific times and sensations are more useful than general phrases like "felt bad."
Why the Log Helps
An examiner works from what you can describe. Memory tends to blur over several days, and a bad afternoon can feel like a bad week. A written record shows patterns, such as whether symptoms climb on days with long screen sessions or whether they seem unrelated to screen use. It also helps you separate activities that clearly make things worse from those that may not matter much. Bring the log to your visit and read it aloud or hand it over, whichever you prefer.
The log is also useful for you. Seeing your own hours on paper often reveals habits you did not realize you had, like checking messages every few minutes or working through lunch without moving. Small changes, such as raising a laptop to a stack of books or setting a timer to stand every half hour, are easy to test and easy to record. Whether any change helps is something to note, not something to assume.
Keep It Simple and Consistent
Use the same format every day so the entries are easy to compare. A basic table with columns for date, screen hours, setting, device height, and symptoms works well. Keep it going for at least a week, and longer if your symptoms come and go. If you miss a day, leave it blank rather than guessing later.
Do not change your whole routine just to make the log look neat. The goal is an accurate picture of an ordinary day, not a perfect one. If you find yourself avoiding screens entirely to protect your neck, write that down too, because it tells your examiner something about how the injury is affecting your daily life.
When Not to Wait
A screen log is a record for an examination, not a substitute for one. If you notice numbness or weakness in an arm or hand, trouble with balance, confusion, slurred speech, trouble swallowing, a sudden severe headache, or pain that is getting worse quickly, do not wait for a scheduled visit. Seek emergency care right away. For ordinary, non-urgent concerns about your neck or how you feel after a crash, bring your log to a licensed clinician who can examine you in person and explain what they find.
