Scientists in the USA have found a strong link between headaches and warmer weather. For many years people have believed that sudden increases in temperatures cause headaches. Doctors at a medical centre in Boston now say they know it’s true. Researchers did a study on 7,054 patients who went to hospital because of a headache. Their research showed that the main cause of the patients’ headaches was a change in the weather. A rise in temperature in the previous 24 hours was the biggest trigger. The research team said the chances of getting a bad headache increased by 7.5 percent with every five-degree Celsius rise in the temperature. The second biggest cause was a fall in air pressure, which happens especially after thunderstorms.
Lead researcher Dr. Kenneth J. Mukamal of Harvard Medical School gave a simple explanation of his research. He said: “In the summer, you may think that ice cream sets off your migraine. But it wasn’t the ice cream, it was the temperature increase on that very hot day that led you to eat the ice cream.” Dr. Mukamal added: “Our results are consistent with the idea that severe headaches can be triggered by external factors. These findings tell us that the environment around us does affect our health.” One doctor said to avoid headaches, we should stay away from things like coffee and wine when the weather suddenly gets hotter. Bad headaches and migraines affect millions. Around 18 percent of women and six percent of men suffer from them.
