What Your Headache Is Trying to Tell You

Common causes of headaches, including diet, stress, and allergies.

Headaches come in many forms, from occasional to chronic, from mild to migraine. But whatever type of headache you experience, your body is trying to tell you something important about your lifestyle and health.

Dehydration

One common cause of persistent headache is chronic, mild dehydration. Dehydration headaches frequently occur after exercise, accompanied by irritability and poor concentration. The more severe your dehydration, the more intense your headache; dehydration is one of the primary triggers for people who suffer from migraines. 

Luckily, there’s an easy solution. Studies have found a decrease in both mild and severe headaches when participants made a conscious effort to drink more water throughout the day. 

Skipping Meals

Not eating enough can also cause headaches. These “fasting headaches” are usually caused by skipping meals, and they can range from mild background pain to severe tension headaches. Fasting headaches are often accompanied by irritability, nausea, and brain fog.

One study in Denmark found that fasting headaches usually happen within 16 hours of skipping a meal. The good news is that eating will resolve the headache; the bad news is that it can take a full 72 hours. Eating regular meals is the only way to prevent fasting headaches; if you do miss a meal, try eating a high-protein snack to keep your stomach full. 

Anxiety

In the last decade, many studies have linked stress levels, anxiety, and headaches. 

Headaches are both more frequent and more severe for those with depression or clinical anxiety, but people without chronic conditions can still experience anxiety or stress headaches. A study of hospital data in Greece found that the high-anxiety period of the economic crisis resulted in higher tension headache levels in the general population and more patients seeking treatment for headache pain. One research team in Nepal found that women are more likely to experience anxiety headaches, though they appear in men as well. 

It’s not just adults who suffer from stress headaches. Studies in China linked high levels of academic stress to students’ headaches, and children with anxiety disorders show a higher frequency of headache symptoms than children without such disorders. 

Anxiety headaches are often accompanied by sleeplessness or neck pain. If you have either of these symptoms along with a headache, take a look at the stress levels in your life. You might be experiencing an anxiety headache. 

Poor Sleep

If you’ve experienced a sleepless night followed by a pounding head the next day, you’re not alone. Many studies have found a link between fatigue and headaches, but the reason can vary from person to person. 

One study found that insomnia is directly linked to frequent headaches. Other research shows that chronic migraine and tension headache sufferers may need more rest than the general population, making them more likely to have a fatigue headache even after getting what should be a full night’s sleep. 

Some studies also show a link between headaches and a lack of sleep due to breathing disorders such as snoring or sleep apnea, while a separate study in Taiwan simply found that poor quality sleep is linked to headaches the next day. 

Though the exact relationship between headaches and sleep is still being investigated, the overall results agree: getting enough sleep is essential to staying headache-free. If you frequently wake up with a pounding head, talk to your doctor about improving the amount and quality of your sleep. 

Allergies

If your headaches are accompanied by itchy eyes and runny nose, the problem may be allergies. One recent study found that the frequency of migraine attacks is higher for people with dust and pollen allergies, and other research found that sinus headaches are often triggered by allergens.

Food allergies can trigger headaches also. One study into gluten sensitivity found that people with celiac disease and wheat allergies both suffer from headaches after ingesting wheat. Other potential allergens, such as nuts and certain spices, also show a link to headaches

However, some “sinus headaches” might actually be chronic migraines, according to one 2016 study. If you frequently have sinus pain with your headaches, talk to your doctor; you may be experiencing a migraine. 

Hormonal Fluctuations

Though studies have found that both men and women experience headaches due to hormonal fluctuations, women are more likely to have headaches than men during their reproductive years.

Separate studies have found that women experience headaches associated with menstruation, pregnancy, and menopause, all periods of time when hormone levels are in a state of flux. Other research found that women who suffer from migraines experience their most intense attacks during menstruation; these headaches last longer than non-menstrual headaches and are often accompanied by nausea.

No matter the cause of your headache, talk with your doctor. There are many options for treatment available, including painkillers, antihistamines, synthetic hormones, physical therapy, acupuncture, and lifestyle modifications
