In this stressful and busy life, headaches and migraines are pretty common. But what exactly are the triggers, and does dehydration cause headaches as well?
Headaches are among the most well-known factors of distress that can negatively influence everyday life. But do you know what the fundamental indications that dehydration might be the reason behind a headache are?
There are various distinct types of headaches. Most adults suffer from headaches at some point, even if they don’t become a regular occurrence.
Many kinds of headaches are easily treated and can be pretty simple to avoid. Among those kinds, dehydration headaches are widespread. And with this guide, you will be able to get the answers to does dehydration cause headaches along with its symptoms and treatment.
1. What is a Dehydration Headache?
Before you find out the answer to “does dehydration cause headaches?”, you will need to understand what a dehydration headache is. Human bodies need plenty of water to function properly, and the lack of the required amount of water is known as dehydration.
And the headaches caused and triggered by the lack of water are called dehydration headaches. A dehydration headache occurs when you are dehydrated due to a lack of fluids. Headaches and migraines frequently happen with other dehydration indications, including dizziness, extreme thirst, and dry mouth. The pain generally stops after drinking water, getting enough fluids, resting, and taking prescribed medication.
You can also suffer from headaches even from very mild dehydration; therefore, always providing your body with the necessary fluids is extremely important.
The good news is that most of the time, dehydration headaches get better with simple home remedies such as drinking water, getting some rest, and taking pain medications. However, in case you experience symptoms of serious dehydration, like confusion and feeling faint, you must get medical help as soon as possible.
Medical and health professionals are not sure about the number of people suffering from dehydration headaches. Inadequacy of liquids can lead to dehydration, which in turn triggers headaches and migraines. Infants, children, and aged adults have an increased chance of dehydration. Individuals with specific health disorders like diabetes are also more susceptible.
2. Symptoms, Causes, and Prevention of Dehydration Headaches
To answer the question – does dehydration cause headaches, the factual answer is yes. Proper lack of fluids and water can trigger headaches and migraines, which can hurt your daily life.
But there is much more to know about dehydration headaches, their symptoms, causes, prevention, and treatment.
2.1) The Symptoms of Dehydration Headaches
Pain and discomfort due to a dehydration headache can vary from mild to extreme. You may experience agony all over your skull or in only a single area, like the end, front, or side. The pain is generally similar to a dull throb, but it can also become pretty intense.
You may experience a pulsing headache, or the distress might get consistent. The pain can get severe when you perform some tasks or try the movements like bending over, shaking your head, or walking.
Along with these, you will find many more dehydration warnings that also happen with the pain in the head. Some such dehydration symptoms are:
- A darker hue of urine and a reduced need to urinate
- Facial Pain
- Dizziness and confusion
- Dryness in the mouth
- Reduced appetite
- Extreme Sweating
Syncope, blue lips, and blotchy skin are severe symptoms of dehydration, and in such cases, the patient should be immediately given proper medical attention.
2.2) How Does Dehydration Cause Headaches?
As you can gather from the name itself, dehydration headaches occur simply due to a lack of the required body fluids.
When you don’t get enough water and fluids, your brain, along with other tissues in your body, shrinks. And when your brain contracts, it gets pulled away from the skull. Due to this, the pressure gets applied to your nerves which in turn causes pain.
Even the mildest of dehydration can result in a headache or migraine. When you consume proper nutrients, drink water, and the necessary fluids, your brain returns to its earlier volume, and therefore, the pain also goes away.
To address the question of does dehydration cause headaches, the short and precise answer is yes. And as to “why does dehydration cause headaches?” – the only explanation is a lack of adequate fluids in the body.
2.3) How to Prevent Dehydration Headaches? Some Simple Tips
The ideal way to prevent a dehydration headache is to keep well hydrated. So now that you know “how does dehydration cause headaches?” – there are many steps that you can take to avoid such headaches, some of them being:
i) Drinking Water
Drinking plenty of water and fluids is the best way of preventing dehydration and, therefore, dehydration headaches. Always keep a water bottle when leaving the house, and remember to take small sips throughout the day.
ii) Always Stay Hydrated
Don’t wait for the thirst to come before taking a sip. Make sure to hydrate before you feel thirsty and drink fluids at regular intervals. Waiting to feel the thirst before drinking water is a sure way to dehydrate.
iii) Replace Lost Fluids
Replacing the fluids you lose is also another critical point. In times of strenuous exercise or physical activities, taking frequent water breaks is very necessary. When you are in the middle of some sports or games, it is easy to forget the needs of the body. So it is essential to remain aware that you can get dehydrated after sweating due to exercise. And replenishing the fluids accordingly is a necessity. As you know, the body loses water faster while performing intense physical activities, so water intake is necessary to avoid a migraine attack.
Regular and frequent rest breaks are another way to prevent dehydration. Give attention to your body and its needs. If you feel weak, exhausted, or dizzy, immediately take a water break and sit briefly.
v) Protection From Heat
Make sure to have proper protection from the heat. When you are out in hot weather, hydrate more frequently. Take breaks continually, and find a shady area to stay cool and avoid overheating.
2.4) When to Seek Medical Help?
The treatments in this guide will get temporary relief and, in many cases, will cure the headache well. But if the symptoms worsen and the headache persists, seek professional help. The instances in which you should get medical attention are:
i) Worsening Pain
Call your physician when you still have a migraine, even after following all the instructions like drinking fluids, resting, and taking pain relief and drugs.
ii) Continual Pain
Regular and recurring headaches and chronic migraines with serious pain can be a symptom of some other severe health problems.
iii) Having Other Symptoms
Such symptoms can include vision problems or blurry vision, dizziness, queasiness, and upset stomach.
Dehydration can also result in serious health issues other than headaches. If you or someone you know show symptoms of dehydration, ensure proper medical help is provided.
Generally, dehydration headaches are not severe and go away on their own. If you are looking for some simple home remedies and relief, read on to find easy ways to treat dehydration headaches.
3. Why Does Dehydration Cause Headaches? 5 Easy Treatments
Caused by a lack of proper nutrients and fluids, dehydration headaches are pretty easy to treat. As mentioned, the human body cannot function with adequate nourishment; therefore, lack of water triggers headaches and other ailments.
Occasionally, dehydration headaches get better given time and with some simple home remedies. To reduce pain due to dehydration and get headache relief, you can try treatments like taking fluids, resting, pain medications, and other remedies for common headaches.
3.1) Drinking Plenty of Water
Try taking little sips of water as gulping down it too fast can make you sick. Remember, since the ailment is caused due to lack of fluids, suddenly giving too much water to your body can shock the system and make you sicker.
You can try gently sucking on ice cubes if you feel sick in your stomach.
The best way to cure the headache pain caused by dehydration is to address the fluid loss. Drinking water or sucking ice cubes are the first things to try for headache treatment.
3.2) Electrolyte or Sports Drinks
Electrolyte drinks like sports drinks are also an excellent way to replenish and regulate your fluids. However, since such drinks generally have high amounts of sugar and artificial colors, drinking in moderation is also necessary.
Drinks like Gatorade work in two ways as they address both the pain and the matter of dehydration. They come in several fun colors and flavors like Lemon Lime, Fierce Blue Cherry, Glacier Freeze, and many more.
But remember that dehydration headaches can usually be treated with plenty of fluids and water. So before consuming such sugary colored drinks, try to maintain a proper and healthy diet.
3.3) Relaxing and Resting
One of the best ways to cure headaches is to temporarily avoid physical movement. You will find that even the slightest movements like shaking your head, getting up, or changing position can jar and increase the intensity of pain in your head.
So relaxing and resting is one of the ideal ways to treat migraines and avoid pain.
If you are outside in the sun, try to find a cool shade and relax briefly. Closing your eyes and avoiding intense light or sun rays can also provide some relief. Giving your body enough time to rest and heal would be best.
3.4) Using Ice or Cold Compress
Using a cold compress on your head can give you some much-needed comfort, and the cool temperature of the compress will help relieve the pain.
A soft and wet washcloth is a good alternative if you don’t have a compress. Place the cloth on your forehead; most of the time, you will get almost instant relief. It will probably not cure your headache completely, but it will provide some relief.
3.5) Taking Pain Medications
When all else fails, relief can only come from pain relievers or prescription drugs. However, this one is a tricky area and is better to explore only with the guidance of a medical professional. You must not take strong painkillers without consulting your physician or health professional.
Some of the ordinary and effective painkillers you can use for headaches are ibuprofen, acetaminophen, and aspirin. Bufferin, Advil, and Tylenol are all considered to be effective in providing relief from any headache.
Always ensure that the medication does not contain any caffeine, as it can further increase the dehydrated state of the body. And it is better to take medicine with water or food, as an upset stomach on top of a migraine is not desirable.
Finally, you should consult your doctor or physician if the symptoms of a water deprivation headache worsen. While these remedies might be effective for mild and moderate levels of headaches, for severe cases, immediate medical attention is needed.
Remember that while these treatments and remedies can be helpful in mild and even moderate cases, the serious ones need immediate and proper treatment. Extremely dehydrated patients will require additional care. Many may even have to get admitted to the hospital to monitor their fluid intake and recovery. Medical professionals usually treat severe dehydration with IV fluids. Giving intravenous fluids is the next step if the fluid consumed is too low.
Another thing to keep in mind while treating dehydration is to avoid caffeinated beverages and alcoholic drinks. Those can increase urine output and thus increase the chance of getting dehydrated.
To treat severely dehydrated patients, replenishing fluids are the only solution, along with rest and medication.
