8 Migraine Triggers That You May Not Be Aware Of

Migraine is a common condition in the world population. Know what are the causes that perhaps you did not know; so you can prevent them by changing some habits.

It is characterized by causing an intense headache. It usually occurs on one side only or in areas such as the temple, forehead, or around the eyes. It is also linked to various symptoms such as hypersensitivity to light, intolerance to noise, nausea and vomiting. But what are the causes of migraine?

Unlike headaches, this disorder worsens over time and can become a reason for disability. In fact, according to data from the World Health Organization (WHO), migraine is one of the 10 most disabling diseases worldwide.

In some cases, the pain lasts for up to 72 hours and is difficult to alleviate with pain relievers. And, although how it develops is unknown, it is believed to be related to hormonal changes that cause blood vessels to tighten. Take note!

Possible causes of migraine

It is difficult to know how a migraine occurs. So we share the 8 main factors, collected by the specialist María Elena Navarro Calvillo, that could influence this alteration so that you try to avoid them.

1. Eating food while you work

Meal times should be respected. However, as a consequence of multiple commitments, some ignore them or eat them while doing other activities.

According to a study published in 2019 by the Journal of Neurological Sciences , this has been related to an increase in headaches and other symptoms of migraine. Apparently the distraction it causes in the brain causes serotonin levels to drop ; the wellness hormone.

2. Sleep disorders

Too little or too much sleep can trigger migraines. By not giving the body the necessary hours of sleep, some of its functions are performed poorly.

The problem is that, in addition to the lack of concentration, there is a strong feeling of fatigue. So it is difficult to carry out daily activities. In addition, these difficulties also appear when you rest excessively; since the vital rhythms change and, consequently, disorders are created in the organism.

3. Ingesting alcoholic beverages in excess

Excessive consumption of alcoholic beverages can increase migraine episodes by up to 30%. 

Ethanol, one of the compounds in these drinks, causes the body to become dehydrated and have imbalances in body fluid levels. As a consequence, circulation problems occur, oxygen delivery to the brain decreases and a severe headache is generated.

4. Eat fast foods and cold snacks

Although it is the most ignored factor, diet is related to the constant appearance of migraines. Fast foods, cold snacks and a wide range of processed foods generate negative reactions on a physical and mental level.

For example, expert Katherine Zeratsky explains that monosodium glutamate (a flavor enhancer found in processed products) affects  inflammatory processes in the body ; causing these types of conditions.

5. Strong smells

Often, those who suffer from constant migraines have relapses when they perceive a strange or too strong odor.

And is that perfumes, air fresheners or some chemicals in everyday products can cause this reaction.

6. Temperature changes as one of the causes of migraine

Along with sudden changes in temperature, a series of consequences are triggered in the body ; such as a weakening of the immune system, colds and headaches.

Going from hot to cold, or vice versa, causes some people to release substances that cause migraines. This was demonstrated by the following pilot study carried out in Germany between June 2011 and February 2012:

7. Loud sounds or bright lights

Bright lights or prolonged exposures to loud sounds cause blood vessels to constrict, leading to this disorder.

Along these lines, this can also occur due to continued exposure to sunlight.

8. Being overweight or obese

Some are not aware of the consequences of having a lack of control in body weight. Both being overweight and obese increase the risk of cardiovascular disorders and other conditions.

As it is a main cause of circulatory problems, it is not surprising that it also influences the constant cases of migraine.

Identify the causes of migraine early

After knowing the possible causes of migraine, it is important that you analyze your habits and identify if you are exposed to any of them. If so, try to increase prevention measures so that you do not have to suffer it continuously.

However, if you suffer from these complaints often, it is crucial to contact your doctor. He will be able to detect the problem in time to know what it may be.
