Headaches? These 10 Things Might Be The Cause

According to an estimate, seven out of ten10 individuals experience at least one headache every year. So, if you are among those suffering from pain and discomfort in the head now and then, you are not alone.

A headache is a pretty common condition. It may be mild sometimes, but it also can disrupt your daily routine because of its severity. In fact, around 45 million Americans experience severe headaches, making them unable to perform their routine activities.

You can often easily manage your headaches with medication and lifestyle changes. However, you should not just shrug it off as something normal. While most headaches are not because of a severe illness, some may be signs of a condition requiring emergency care.

Causes of Headaches

Here are the causes of headaches commonly linked with the symptom. They may or may not be an actual cause. Contact a doctor for an accurate diagnosis.

1. Stress


That dull pain in your head or feeling like a clamp squeezes your skull can be due to stress. A stress-caused headache is called a tension headache. It can prolong from half an hour to a few days. Mostly, it starts gradually, too, in the middle of the day.

Tension headaches usually do not disrupt a person’s day-to-day routine. Neither do they impact your balance, strength, or vision. Moreover, women are more susceptible to this kind of pain.

The symptoms of pain occurring out of stress include moderate to mild pain, a pressure in the top, front, or sides of the pain. It is also characterized by trouble sleeping, tiredness, mild sensitivity to noise or light, muscle aches, and difficulty focusing.

Apart from stress, several other factors cause these symptoms. They include hunger, bad posture, low iron levels, depression, caffeine, dental or joint problems, anxiety, and fatigue.

2. Ear Infection

If you have a headache, irritability, stiff neck, excessive sleepiness, confusion, and severe stiff neck, it may be due to an ear infection. Some of these symptoms may not arise, but if you have a headache for no apparent reason, it may be a sign of an infection.

An ear infection is a viral or bacterial infection that affects the middle ear. Children are more likely to have this condition as compared to adults. It is usually excruciating because it inflames the middle ear and builds up fluids.

Another major symptom among adults is diminished hearing; among kids, it is the loss of balance.

3. Concussion

Although the symptoms and signs of a concussion are usually subtle, headache is its visible sign. It can last for days, weeks, and even longer. If a person, who suffered from a concussive brain injury, experiences a headache accompanied by memory loss and confusion, he may be facing a concussion.

This condition is a traumatic brain injury that encumbers the brain function. Its effects are usually temporary and include problems concentrating, coordinating, and balancing.

A blow to the head usually causes a concussion. So, if you experience a head injury, it is prudent to contact a doctor even if emergency care is not required.

4. Dehydration

Dehydration is another cause of a headache. The pain caused by dehydration can be relatively mild or severe as a migraine.

Dehydration occurs when your body uses or loses more water than it takes in. Sometimes, your body is losing water faster than it can be replenished, like vomiting or diarrhea.

When your body is dehydrated, your brain can temporarily shrink or contract from fluid loss. It ultimately causes a headache, which goes off when you rehydrate your body.

This headache accompanies dizziness, confusion, reduced or red-colored urine, fatigue, dry mouth, low blood pressure, increased heart rate, and extreme thirst.

5. Influenza

Influenza is a viral infection that affects your respiratory system, i.e., your throat, nose, and lungs. Commonly called flu, it is another condition that causes a headache.


People suffering from this headache sometimes become sensitive to light, smell, and sound. However, if a headache persists after other symptoms disappear, it may not be flu or cold. Instead, it can be a migraine or a tension headache.

If you have nasal congestion, aching muscles, a fever over 100.4 F, and a headache, you are most likely to suffer from the flu.

6. Sinus Infection

If you have a headache, runny nose, fever, feeling of fullness, and swelling in your face, you are likely to have a sinus infection. Another sign that your headache is due to sinus infections is that it aggravates with a sudden head movement.

It is a recurring headache, like tension headaches or migraines, and is usually mistaken for these pains. Its treatment involves tackling the infection and relieving the symptoms. But all this requires a health care professional who may suggest you antibiotics, decongestants, or antihistamines.

You can also feel better with home remedies like drinking more fluids and using a saltwater nasal spray and a humidifier.

7. Medications

Medication overuse can also be a reason for your headache. This headache, also known as a rebound headache, is caused by long-term, regular medication used to treat headaches like migraines. If you take pain relievers for a headache for over a couple of days, you can have another headache.

If a person has a headache disorder, any medicine he/she takes for pain relief can lead to rebound headaches. However, one can take pain relievers regularly for other conditions like arthritis. They are not known to cause medication overuse headaches.

A rebound headache dissipates when a person stops taking the pain reliever. It bothers when the person wakes up and occurs every day or almost every day. It may improve with a pain reliever but returns when the medication wears off.

8. Stroke

A sudden, severe headache can indicate a stroke, especially when accompanied by dizziness, vomiting, or altered consciousness.

A stroke occurs when there is an interruption in the brain’s blood flow. It has two types, i.e., ischemic stroke and hemorrhagic stroke. The former occurs when an artery to the brain gets blocked. It causes the brain cell to die due to the absence of blood flow.

A hemorrhagic stroke occurs when a brain artery bursts and causes bleeding in the brain. In this type, severe headache is the only symptom in one-third of the cases.

If you have severe pain, double or blurred vision, and a loss of sensation, you have a stroke headache.

9. Low and High Blood Pressure

It is well known that high blood pressure causes a headache. However, it is a lesser-known fact that low blood pressure can also lead to a headache.

The change in the pressure in your skull causes a headache. If the pain aggravates when you sit or stand, it can be because of low blood pressure. It will improve when you lie down.

A headache due to high blood pressure sometimes starts with neck pain or at the back of the head. It worsens with sneezing, exertion, and coughing and can be felt all over the head. This headache also accompanies muffled hearing, ringing in your ears, nausea, and dizziness.

A headache from high blood pressure is characterized by throbbing or migraine-like pain and is usually worse in the morning. It can also come with neck and shoulder pain. Moreover, this headache can aggravate with sneezing, coughing, or exertion. It also causes ringing in the ears or changes in vision.

10. Shifting Hormones

Shifting hormone levels can also be a cause of a headache in women. The shift in hormone levels can occur during periods of menopause and pregnancy. It can occur from birth control pills and hormone replacement therapy.

There are also menstrual migraines that can happen two days before your periods or for the first three days after your periods start.

You may also want to know what different headaches are because each has another cause. Here’s some stuff about common headaches.

Types of Headache

Headaches are of different kinds that have their own set of symptoms. When you know the type of your symptoms, it becomes easy for you and your doctor to find a solution to your pain. There are 150 types of headaches, depending on the symptoms and causes. A few of those kinds, which are more common, are explained below:

1. A Migraine

A throbbing, pounding pain marks a migraine headache. It can continue from 4 hours to three days and occurs one to four times monthly. It happens on one side of the head.

A migraine is primarily a neurological condition that gives rise to multiple symptoms. Along with the pain, people face other symptoms like sensitivity to smells, noise, or light; vomiting or nausea; belly pain or upset stomach; and loss of appetite.

It can hit a person in childhood, while in some cases, it may arise in early adulthood. A few children’s migraines come with digestive symptoms like vomiting and happen once a month.

Women are more likely to have a migraine than men are. The most common risk factor for this condition is family history.

2. Cluster Headaches

This headache is non-throbbing and marked by excruciating, burning pain behind the eye or on one side of the head. In a cluster headache, the eyes tear up and cause nasal congestion, runny nose, or rhinorrhea.

A cluster headache can continue for long periods, called a cluster period. It can occur every day and even more than once a day. There is no known cause for this type of headache.

This kind is rare and usually affects men aged 20 to 40.

A cluster headache starts a few hours after you have fallen asleep. It is usually painful enough to wake you up. In some cases, it can also begin when you are awake. It becomes severe after 5-10 minutes it starts. The most intense pain persists between half-hour and 2 hours.

3. Exercise Headaches

This headache arises when you exercise or do something physically demanding. What happens is that when you are exerting yourself, your muscles of the neck, head, and scalp need more blood to circulate. As a result, your blood vessels dilate, leading to an exertional or exercise headache.

Although they may be unrelated to other factors, they are common in individuals having an inherited vulnerability to a migraine, i.e., one or both parents have a migraine.

This kind is benign and fades off with the usual headache treatments. However, it would be best not to assume that your new exertional headache may be due to exercise. It would be best to rule out other causes for which you must go to a doctor.

4. Thunderclap Headaches

A thunderclap headache lasts for a short time, but it is intense in nature. It begins suddenly and does not intensify gradually. Rather, it is very intense and painful as soon as it starts. Those who have experienced it describe it as the worst pain of their life.

This kind of headache can be a sign of a life-threatening condition. It is associated with some bleeding in your brain. Therefore, you must solicit medical attention when you experience the pain.

There is a possibility that it may be something benign; still, it should be checked immediately to locate the reason. Its symptoms include severe, sudden headache; fainting, vomiting, nausea; and neck or lower back pain apart from your head.

5. New Daily Persistent Headaches

This headache can start suddenly and continue for three months or even longer. The reason for this pain is still unknown. However, some notice that it hits after a flu-like illness, an infection, a stressful event, and surgery.


A headache is among the significant reasons for leaving work in the middle of the day or dropping a class at the university. The pain may be in the same body part but has different types. The correct diagnosis makes possible an effective treatment. Therefore, diagnosing the kind of headache is very important.
