Caffeine 'can ease headaches'
![]() Filter coffee contains the highest dose of caffeine
A cup of tea or coffee might be able to tackle certain types of headache, say researchers.
The caffeine it contains could help a higher number of people gain complete relief from "tension headaches". Caffeine is already routinely added to many painkilling medications, including some which can be bought over the counter at chemists, and the latest research confirms that it has therapeutic value against conventional headache symptoms. But researchers at the Diamond Headache Clinic in Chicago also found that giving caffeine in isolation appeared to be as useful as giving standard pain relief.
Tension headaches involve constant, dull pain, although not generally as excrutiating as a migraine. Just as good Pain is often accompanied by muscle tightness in the shoulders and neck - and can last for days. The Diamond team found that when caffeine was added to standard painkillers, 70% of patients reported complete relief, as opposed to 58%. On average, Britons are still said to consume 3.5 cups of tea a day. Some studies have suggested that other chemicals in the drink may have health benefits. However, the overall health benefits of caffeine are less clear-cut. Some studies have linked high caffeine consumption with an increased number of headaches. Caffeine can cause, in higher doses, a temporary rise in blood pressure, and some doctors suggest that people with heart rhythm problems should avoid it.
