Many doctors believe that people commonly mistake a migraine headache for a sinus headache. This can be because migraine headache causes can be similar to what most people think causes sinus headaches.

One of the migraine headache causes people commonly mistake for sinus headache causes is the weather. The change in air pressure causes many people to have migraine headaches, some people are so sensitive to this change that even high humidity can change cause migraine headaches.

Food Sensitivities

Food sensitivities can also cause migraine headaches. Common foods are dairy products, artificial sweeteners, chocolate, alcohol, processed meat products (lunch meat, hot dogs), caffeine, and most fatty foods.

For a person to determine if their migraine headache cause is food related there are simple tests that can help to make this clear. A doctor may suggest omitting the suspect food from the person's diet for a set amount of time or keeping a food and headache diary, recording what foods the person eats and which of those days headaches occur to try to establish a pattern.

Environmental Factors

Some migraine headache causes are from a person's surroundings such as bright lights, strong smells or rhythmic motion. There are many external migraine headache causes which people cannot always avoid, these people may be able to take some precautions such as wearing sun glasses or taking an over the counter motion sickness medication if the nausea leads to headaches when traveling.

Mental Stress

Stress is a common cause of migraine headaches. Many people have anxiety from situations in the work place, at home, with family, and many other situations which lead to severe headaches.

Depression has also been linked as a possible migraine headache cause; when people suffer from depression they tend to use extra stimulants such as coffee or nicotine to compensate for their moods which can also cause migraine headaches. Some people also tend to consume alcohol when they are depressed to cope with their feelings. An excess of alcohol is also a known cause of migraine headaches.

Physical Causes

A disruption in a person's normal sleeping pattern can also be one of a migraine headache's causes, every person's body requires a unique amount of sleep, for most people that is between six and nine hours each night. When a person has trouble sleeping it can affect their whole next day by plaguing them with severe head pain, nausea, and sensitivity to light or sound.

This can also be true if a person is getting too much sleep either all at once or by napping throughout the day. Most people thrive on sleeping for a set amount of time each day waking and sleeping at the same times, for some migraine headache sufferers regulating their sleeping pattern could reduce their occurrence of headaches immensely.

There are many more migraine headache causes, if a person thinks they may be suffering from migraine headaches, they should consult a doctor. No one should suffer with migraine pain because there are so many medications, some with very rare and mild side effects which can help migraines last less than an hour instead of hours or days which are common to some sufferers.
