Headaches have become a common problem for many people because of busy lifestyles, workplace pressure, prolonged screen time, lack of sleep and psychological stress.When a headache strikes, some people turn to a cup of hot tea, while others prefer coffee. Regular coffee drinkers may even develop a headache in the morning if they skip their usual cup.But how effective are tea and coffee in relieving headaches? Experts say it depends on the type of headache, the amount of caffeine consumed and a person’s daily habits.Why caffeine may reduce headachesCaffeine, a natural stimulant found in tea and coffee, can affect blood vessel activity in the brain. In the early stages of migraine or in some cases of tension-type headache, a limited amount of caffeine may help reduce pain.This is also why caffeine is included in some over-the-counter painkillers. It can enhance the effectiveness of these medicines and help relieve pain more quickly.However, caffeine does not affect everyone in the same way.Too much caffeine can make headaches worseDrinking tea or coffee repeatedly whenever a headache occurs does not necessarily provide faster relief.Excessive caffeine consumption can increase the risk of rebound headaches, including headaches associated with overuse of medication.People who regularly consume large amounts of caffeine can also become dependent on it. Suddenly reducing or stopping caffeine may cause withdrawal symptoms such as headache, fatigue, difficulty concentrating and irritability.In other words, caffeine that once helped relieve headaches can eventually become a contributing factor when consumption becomes excessive.Coffee is not a solution for every headacheTea or coffee will not be equally effective for all types of headaches.Headaches caused by dehydration, high blood pressure, sinus problems, infections or other medical conditions cannot simply be treated by drinking coffee.For some people, caffeine can also increase anxiety, accelerate the heartbeat or interfere with sleep, which may further aggravate headaches.What to do when a headache startsThe first step is to consider whether dehydration could be contributing to the headache. Drinking enough water and resting for a while in a quiet, dimly lit environment may help.Spending long periods looking at a mobile phone, computer or television screen can also put additional strain on the eyes and brain. Taking a break from screens may therefore be beneficial.It is also important not to remain hungry for long periods. Eating healthy meals regularly can help, as low blood sugar can trigger headaches in some people.When medical advice is urgently neededA sudden headache that is the worst headache of your life should not be ignored.Urgent medical attention may be necessary if a headache is accompanied by fever, a stiff neck, repeated vomiting, numbness or weakness in the limbs, difficulty speaking or blurred vision.People should also consult a doctor if headaches occur regularly, do not improve after taking painkillers, or suddenly change in pattern or severity.Moderation is keyA cup of tea or coffee may provide temporary relief for some people when a headache begins. However, caffeine should not be considered a permanent treatment for headaches.Rather than becoming dependent on caffeine, headache management should include adequate water intake, regular and sufficient sleep, a balanced diet and stress management, along with moderate tea or coffee consumption.
