If you have a headache, here are some things you can do. First, try to rest in a quiet and dark room. Relax and close your eyes. Applying a cold or warm compress to your head may also help relieve the pain. Drink plenty of water to stay hydrated. Avoid loud noises and bright lights. If the headache persists or is severe, you can take over-the-counter pain relievers like ibuprofen or acetaminophen. However, if the headache is very severe, accompanied by other symptoms like nausea, vomiting, or vision problems, seek medical attention immediately. ????
