Norwegian National Headache Center from Trondheim reveals that high blood pressure does not increase the risks for headaches and migraines as previously thought. A study they performed went further and found that people who suffer from high blood pressure are less likely to have headaches and migraines.

Scientists examined data from two large studies that included over 120000 people. The first study took place between 1984 and 1986 and examined the link between blood pressure and diabetes. The second study occurred between 1995 and 1997 and questioned headache frequency and had blood pressure measures as well as about taking blood pressure drugs that are also used in migraine treatment.

Those people with who measured higher systolic blood pressure were 40% less likely to have headaches while those with higher pulse pressure had 50% lower rates of headaches.

The study also gave an idea about how hypertension affects headaches: high blood pressure occurs because of stiffer blood vessel, stiffer vessels cause less activated nerve endings and less sensitive nerve endings mean less headaches.

This study is not to useful to the sufferers and general public as it is to scientists. These findings may help uncover the nature of headaches and blood pressure, and develop better treatments for patients.
