Not for the First 24-48 Hours Avoid being alone for the first 24-48 hours after concussion. The initial period carries the highest risk for delayed complications that require emergency intervention: worsening symptoms from brain swelling or bleeding, which, while rare after concussion, are time-sensitive emergencies. Having someone present who recognizes deterioration and calls for help provides a critical safety net (McCrory et al., 2017). After 48 hours without red flag symptoms, the risk of acute complications drops significantly. Most adults with stable or improving symptoms safely resume being alone, with a check-in system rather than constant supervision. The transition from monitored to independent recovery happens gradually, guided by symptom trajectory. The practical challenge: many adults live alone, work alone, or lack available companions for 48 continuous hours. This doesn't mean you need round-the-clock bedside monitoring. It means someone should check on you regularly and know how to reach you. What Monitoring Actually Requires First 24 hours (highest vigilance): Someone should be in the same residence (not necessarily in the same room) Check on the person every 2-3 hours during waking hours Confirm they are oriented and responsive Watch for: worsening headache, repeated vomiting, increasing confusion, one-sided weakness, seizure One wake check during the first night of sleep Hours 24-48 (continued monitoring): Someone available in the residence or checking in every 4-6 hours The person should not drive or operate machinery Continue watching for red flag symptoms Monitor symptom trajectory: are symptoms stable or improving? After 48 hours (transition to independence): If symptoms are stable or improving with no red flags, being alone is appropriate Establish a check-in schedule: text or call a designated person 2-3 times per day Have a plan for emergencies (phone accessible, emergency contacts saved) The check-in system continues until major symptoms have resolved If You Live Alone Ideal approach: Stay with a friend, family member, or partner for 48 hours. Or have someone stay at your place. This is the safest option and worth the inconvenience. If that's not possible: Ask someone to check on you in person at least twice in the first 24 hours Set up a scheduled text check-in with a friend: text "ok" at agreed times (e.g., 9 AM, 1 PM, 6 PM, 10 PM). If you miss a check-in, they call. If you don't answer, they come over or send emergency services Keep your phone charged and accessible at all times Sleep near your phone with the ringer on Leave your front door unlocked or give a spare key to a neighbor (so help reaches you if needed) Know your nearest emergency department and how to get there Technology solutions: Medical alert devices (like those used by elderly individuals) provide a wearable emergency button Smart speakers with emergency calling capability Fall detection features on smartwatches Video check-ins via FaceTime or Zoom (allows the other person to see your face and assess responsiveness) Mobility During Monitored Recovery Gentle movement provides appropriate activity during the supervised recovery period: JME 1 Cervical rotation keeps the neck mobile during the rest-focused early recovery days. JME 14 Chin tucks maintain cervical strength during the reduced activity of the monitoring period. JME 3 Lateral flexion releases bilateral neck tension from resting positions and stress. JME 42 Shoulder mobility provides gentle movement during the activity-restricted first days. Start your 14-day free trial for structured mobility routines during concussion recovery. Independent Recovery Movement JME 68 Shoulder range of motion counters the stiffness from prolonged resting during recovery. JME 151 Thoracic mobility maintains mid-back function during recovery-period inactivity. JME 152 Upper back extension counters the flexed posture from lying down and resting. JME 164 Scapular mobility keeps the shoulders mobile during the reduced activity recovery phase. When to Seek Help Whether you're alone or with someone, these symptoms require immediate emergency evaluation: Headache that worsens progressively and doesn't respond to medication Vomiting two or more times Seizure (any convulsive activity or prolonged unresponsive staring) Increasing confusion (losing track of time, not recognizing familiar things) One pupil noticeably larger than the other Weakness or numbness on one side of the body Difficulty speaking or slurred speech Difficulty walking or severe balance problems Clear fluid from the nose or ears If you're alone and experience any of these, call 911 immediately. Do not attempt to drive yourself to the hospital. If you feel "something isn't right" even without specific red flags, call someone. Trust your instinct. A cautious emergency call is never wrong. Returning to Full Independence Safe signs for resuming normal independent activities: Symptoms are stable or improving (not worsening) You've passed the 48-hour mark without red flag symptoms You feel confident managing daily activities Balance is stable enough to walk safely around your home You can use the phone and make decisions clearly Maintain check-ins even when independent: Continue the text or call check-in system with a designated person until your symptoms are substantially resolved. This takes 5 seconds per check-in and provides an ongoing safety net without requiring in-person supervision. Driving: Do not drive until symptom-free and cleared by your healthcare provider. Concussion impairs reaction time, visual processing, and attention, all critical for safe driving. If you live alone and need transportation, use rideshare services or ask for rides during recovery. Support your recovery with independence through simplmobility's self-guided mobility programming. How long does someone need to stay with me after a concussion? Someone should be present or checking on you regularly for the first 24-48 hours. After 48 hours without red flag symptoms, most adults safely manage alone with a check-in system. If symptoms are severe or worsening at 48 hours, continue the monitoring arrangement until evaluated by a healthcare provider. What should the person monitoring me watch for? They should watch for worsening headache, repeated vomiting, seizure, increasing confusion, one pupil larger than the other, one-sided weakness, and progressive drowsiness (becoming harder to wake rather than simply being tired). They should also assess whether you seem like yourself: are you oriented, making sense, behaving normally? I live alone and have no one to stay with me. What do I do? Set up a check-in system: scheduled texts or calls with a friend, family member, or coworker every few hours. Keep your phone charged and nearby. Leave your door accessible. Consider a medical alert device. Ask a neighbor to check on you. If you have no support network, inform the emergency department during your initial evaluation so they can recommend resources or keep you for observation. References McCrory, P., et al. (2017).
