What causes headaches?

Despite the years of research, the real mechanism of most headaches is still a bit of a mystery. It was originally assumed that they were caused by the reduction of blood vessels or tightening the face muscles and heads of the head. Modern studies suggest that headaches can be caused by a low level of natural pain reliever called serotonin. When the levels of serotonin decrease, inflamed neurotransmitters into the face and the scalp sends messages that we perceive as headaches. After the levels of serotonin returns to normal, most of the pain tends to retreat. What can function as a medicine per trigger can cause more damage to another than good. If the current theory of serotonin/neurotransmitter is true, then many drugs used to relax muscles or open blood vessels may not be as effective as it was once believed.

One of the most common causes of headaches is emotional stress or depression. Feelings of anger or anxiety can cause muscle tension in oWitches and scalp, leading to a fully blowing tension of the head. Insomnia and depression can also cause headache, which gives some credibility of the connection between serotonin levels and irritation of the face nerves. Some scientists suggest that the emotions themselves do not start headaches, but leave a person more vulnerable to the neurotransmitter/serotonin conflict. Suppressed emotions also tend to cause more pain than expressed anger or anxiety.

other common triggers are sensitivity to food and chemical. Some may be familiar with the concept of Chinese headaches . The main cause of headaches that occurred after the consumption of Chinese meal is the sensitivity to a taste amplifier called monosodium glutamate (MSG). In other foods, MSG may appear on the list of ingredients such as hydrolyzed vegetables.

6 suffering should avoid consumptionACI high levels of chocolate, sour cream, yogurt, aging cheeses and organs. Another chemical that needs to be avoided when fighting headaches is a preservative called nitrity. Many canned or processed meat contains a significant level of nitrites that help maintain fresher meat and provide a healthy pink color. The nitrite trigger mechanism can be the same as the monosodium glutamate, causing pain of allergic reaction.

Some suffers believe that caffeine is a trigger and treatment. Positive is that many headache medicines contain caffeine to accelerate the drug through the digestive system and into the bloodstream. Once the medicine has reached the source of pain, caffeine stimulates the circulatory system for even faster results. Unfortunately, caffeine can also cause headache sensitive people, especially at higher dosage levels. Sudden crash after ingestion of caffeine can also lead to "caffeine headaches", which is a form of withdrawal that is released only over time or morecaffeine.

One common trigger is alcohol consumption. Some red wines contain tyramine that can cause headaches. All forms of alcohol can cause dehydration, the main trigger behind the infamous hangover, which has experienced in the morning after a bout of drinking. Some scientists also believe that alcohol causes blood vessels to expand, which can trigger headaches when they later try to enter into a contract.

other triggers include glare, poor lighting conditions, drug interaction, eye level and physical exertion. Sinus problems are not responsible for a significant number of headaches, although the sinus cavities themselves are very close to neurotransmitters that can be the culprit. It can be very difficult to diagnose headaches, so the trip to the doctor, allergic or eyes, nose and neck specialist (ent) can prove useful.
