Surprising things that give ya Headaches!

Ever been struck by an awful headache and not known why? Maybe your high heels or even a ham sandwich could be the cause.

However if they're severe and very frequent please consult a doctor.

Mobile Phones - With smartphones becoming widely used to do everything from checking emails to reading books and watching TV shows, the small screens are putting our eyes under great strain which leads to headaches.

Lack of Sleep - Over 1,200 migraine sufferers were tested in a study at the Headache Center of Atlanta where they found that those who slept for about six hours a night or less were more likely to suffer from more frequent and severe headaches than those who had more sleep.

High Heels -While there may not be any scientific or biological evidence that wearing high heels can trigger a migraine, muscular tension that heels put on your back can lead to migraines.

Ponytails - Sure it's great when you're having a bad hair day but a tight ponytail or even braids and headbands can strain the connective tissue in the scalp causing pain.

Jogging - Known as 'exertion headaches', any type of physical exertion, such as jogging or pounding a treadmill, causes blood vessels in the head, neck and scalp to swell, producing a build-up in pressure.

Sex - Although quite rare this type of headache is known as a coital headache, where sharp pain in the head occurs almost instantaneously at the moment of orgasm.

Ham - Food triggers are notorious for bringing on a migraine and it might surprise you to know that ham is one of them. Ham contains tyramine, which is a compound known as an amine found in many foods, produced from the natural breakdown of the amino acid, tyrasine. Tyramine can cause blood vessels to dilate and increase blood flow to the brain, triggering headaches.

Going to the Hair Dresser - Having your hair washed lying back over a basin puts your neck in an awkward position which stimulates one of the nerves that brings on a dull headache that could last a couple of days.

Perfume - Strong odours activate the nose's nerve cells, this in turn stimulates the nerve system associated with head pain causing headaches to those with a strong sense of smell.

Coughing - This type of headache is caused by the build-up of pressure in the brain and can be triggered by not only coughs but things like blowing your nose or even sneezing.
