What should I do if I have a headache?
<|assistant|>
If you have a headache, the first thing you should do is to identify what is causing it. Common headache triggers include caffeine withdrawal, lack of sleep, tension and stress, dehydration, fatigue, excessive alcohol consumption, and sensory overstimulation. Once you have identified the cause, you can take measures to either prevent it or treat it. To prevent headaches, drink plenty of water and stay hydrated; practice good sleep hygiene; and get regular exercise. To treat a headache, the best option is often an over-the-counter pain reliever such as ibuprofen or naproxen. If the headache is severe or does not respond to medication, seek advice from a healthcare professional.
