The symptoms of headache, which will get better after a sleep, may be related to headache caused by insufficient blood supply and oxygen supply to the brain due to excessive fatigue or overuse of the brain, which will be relieved after rest. The headache will get better after a sleep, but it may also be related to excessive tension, anger, excitement, emotional instability, etc., resulting in vascular tension headache or neuropathic headache, which will get better through sleep and massage. Headache relief after a good night’s sleep may also be related to headache caused by staying up late, insufficient rest, excessive eye use and bright light stimulation. Migraine, headache caused by wind and cold, or headache caused by cerebrovascular spasm can also be relieved by keeping warm and resting more. If you have a headache and it gets better after rest, you don’t need to worry if it doesn’t come back again, but you should go to the hospital for examination for repeated headaches.
