The Integrated Effect of Physical Activity and Sleep Problems on Concussion Symptom Resolution.
Zackary P Salfi, Mathew J Wingerson, Catherine C Donahue and 4 others
Children and adolescents who were physically active and free of sleep problems after concussion resolved symptoms faster than all three other groups, even after adjusting for symptom severity, anxiety, and time to evaluation.
Key findings
1The physically active, no-sleep-problems group resolved concussion symptoms earlier than all other groups, a finding that held after adjusting for symptom severity, anxiety history, sleep history, and time to evaluation.
2In the adjusted model, the physically active, no-sleep-problems group had hazard ratios of 0.52, 0.56, and 0.38 compared to the other groups, all statistically significant.
3The physically active, no-sleep-problems group also had the lowest rates of persisting symptoms, headache presence, headache severity, and total HBI score at initial evaluation.

What it does not show
Retrospective chart review at a single hospital; findings may not generalize to other populations. Cannot infer causality. It is unclear whether better sleep and activity caused faster recovery, or whether milder symptoms simply allowed better sleep and more activity. Sleep and physical activity were captured with a single yes or no question each. No validated questionnaires, wearable devices, or polysomnography were used. The physically active with sleep problems group had only 9 participants, making that comparison unstable. Mean HBI score at enrollment was 19.6 out of 60, so the sample had relatively low symptom burden. Results may not apply to more severely symptomatic patients. Follow-up visits were scheduled by the treating physician rather than at fixed intervals, producing variable assessment points and some loss to follow-up. Data were collected between 2015 and 2019, before the sixth International Consensus Statement on Concussion in Sport, so clinical guidance at the time differed from current recommendations.
The easy way to misread this
Do not read this as proof that physical activity causes faster concussion recovery. The study is a retrospective chart review using self-reported yes or no answers about activity and sleep, and the physically active group also had lower initial symptom severity. The authors note it remains unclear whether better sleep and activity caused faster recovery, or whether milder symptoms simply allowed better sleep and more activity.
