You need to physically and mentally recover from a concussion. In the first few days after the injury, it’s important that you refrain from physically or mentally strenuous activities. This doesn’t mean sitting in a dark room all day. In fact, studies have shown that complete rest with no stimuli can actually negatively affect recovery.
After the first 48 hours or so, you can gradually start to increase activity levels, such as watching TV and reading. After several days, you can begin to work in some light physical activities such as walking. It is recommended, however, that you avoid strenuous physical activity until approved by your doctor.
In general, work your way back to your daily routine gradually. Talk to your doctor about activities that may worsen your symptoms, and avoid anything too strenuous or demanding until you begin to feel better. Consult your doctor before fully incorporating your regular activities back into your daily life.
