Specifically, this is most importantEarly rest and supervisionFirst day and two: take it easy, both physically and mentally.Have someone who can keep an eye on you, especially the first night.Limit screens and "brain noise"Reduce TV, mobile, gaming and intense reading in the first few days.Dim the light and sound if you are easily provoked by it.Gradually return to activity - do not lie completely still for too longAfter approx. After 24–48 hours, you should cautiously begin light activities (short walks, simple tasks). Research suggests that complete rest for more than two days can prolong the symptoms. Increase a little day by day, but stop and taper off if the symptoms become clearly worse and last until the next day. Avoid new blows to the head. No contact sports or activities with a high risk of falling/collision until you are completely stable and have been assessed by a doctor. Watch for red flags. Seek EMERGENCY help (113/emergency room) for: severe or increasing headaches repeated vomiting pronounced lethargy or difficulty waking up seizures, paralysis, speech difficulties, severe confusion, vision loss. These may be signs of a more serious head injury than just a concussion. Sleep, alcohol and medication Get enough sleep and regularly; Sleep is important for the brain. Avoid alcohol at first - it often worsens symptoms and makes it difficult to detect worsening. Painkillers: follow your doctor's advice (often paracetamol at first). Follow-up if it does not go away. Most people get better within a few days - a few weeks, but some may have problems for several weeks or months. If you have persistent problems or problems with work/school, you should be followed up by your GP (if necessary, you may be referred).
