咖啡可能有助於緩解頭痛 Coffee May Help Alleviate Headaches
It is a common belief that drinking coffee can alleviate pain when experiencing a headache. The caffeine in coffee is believed to constrict blood vessels, which helps relieve headaches. It also affects chemicals in the brain associated with pain perception, increasing pain tolerance. Studies have shown that caffeine can enhance the effectiveness of certain pain relievers, especially for migraines caused by blood vessel dilation. However, individual responses vary, so caution is needed when using it, and it is best to do so under medical advice.
When experiencing mild headaches, drinking coffee can reduce the sensation of pain because caffeine has a vasoconstrictive effect, which is particularly effective for headaches caused by blood vessel dilation. However, excessive consumption may actually exacerbate headaches. Beverages such as coffee and tea contain caffeine.

Caffeine is often added to over-the-counter pain medications such as paracetamol or ibuprofen, which can increase the pain-relieving effect by 5% to 10%, but at least 65mg of caffeine is needed for it to be effective. Caffeine has both benefits and drawbacks for headaches. Whether it's tension headaches or migraines, caffeine added to painkillers shows increased benefits. The pain-relieving effect of caffeine itself requires very high doses, with more than 200mg needed for migraine patients to be effective.

However, it's important to note that excessive caffeine consumption may lead to some side effects, including palpitations, anxiety, and insomnia. For some individuals, caffeine may also trigger or worsen headaches. Therefore, please take precaution when using caffeine to relieve headaches, and it is best done under the guidance of a doctor. Additionally, drinking coffee is just one way to alleviate headaches, not a treatment method. If headaches are frequent or severe, it is recommended to consult a doctor to determine appropriate treatment methods.
