The Power of Hydration: Can Dehydration Trigger Headaches and Migraines?

Migraines and headaches can be quite painful. Although the precise cause of these persistent and nagging headaches isn’t always known, there are often associated triggers. Some migraine triggers include stress, poor diet, changes in the environment, and medication side effects. Although we can identify our triggers and have the potential to avoid them, migraines and headaches can still catch us off guard.

What can cause dehydration?

Dehydration happens when the body loses more fluids than it takes in. The imbalance is caused by inadequate fluid intake, excessive sweating, illnesses and infections, and more. 

Not drinking enough fluids, especially in hot weather or during physical activity, can lead to dehydration. Fever, vomiting, and diarrhea can result in significant fluid loss, leading to dehydration. People with certain illnesses may not feel like eating or drinking, exacerbating the problem. Not only these, intense physical activity, particularly in hot and humid conditions, can lead to excessive sweating, increasing fluid loss.

Some medications, like diuretics (water pills), can increase urine production and contribute to dehydration. If you frequently drink alcohol and caffeine, this can also cause dehydration. Both alcohol and caffeine have diuretic effects, which can increase urine production and contribute to fluid loss. Medical conditions, like diabetes and kidney disease, can affect the body’s ability to regulate fluid balance and lead to dehydration. 

Young children, infants, and older adults are more susceptible to dehydration. Infants may not be able to communicate their thirst, and older adults may have a decreased sense of thirst. Additionally, high temperatures, low humidity, and prolonged exposure to the sun can contribute to dehydration. Pregnant and breastfeeding women may also require additional fluids, and inadequate intake can lead to dehydration. Lastly, traveling, especially to high altitudes, can contribute to dehydration due to changes in climate and altitude.

It’s important to recognize the signs of dehydration, including thirst, dark yellow urine, dry mouth, fatigue, dizziness, and, in severe cases, confusion or unconsciousness.

Can dehydration trigger migraines and headaches?

Yes, dehydration can be a trigger for migraines and headaches in some individuals. Dehydration can lead to changes in blood volume and electrolyte balance, which may affect blood flow to the brain and the overall function of the nervous system. Moreover, dehydration can cause the brain to contract temporarily, pulling away from the skull, which may contribute to the pain associated with headaches.

For some people, the relationship between dehydration and migraines or headaches may be complex, and not everyone is equally sensitive to dehydration as a trigger. It’s important to note that dehydration is just one of many potential triggers for migraines and headaches, and individual susceptibility varies.

Staying well-hydrated is a good practice if you are prone to migraines or headaches. Drinking adequate water throughout the day, especially during hot weather or periods of increased physical activity, is recommended. Paying attention to your body’s signals for thirst is also crucial.

Aside from dehydration, other common migraine triggers include stress, lack of sleep, certain foods and beverages (such as caffeine, chocolate, and certain additives), hormonal changes, and environmental factors. Suppose you are experiencing frequent or severe headaches. In that case, it’s advisable to consult with a healthcare professional for a proper diagnosis and guidance on management and prevention strategies tailored to your specific situation.

Migraine vs. Headache

Migraines and headaches are both types of pain in the head, but they are distinct conditions with different characteristics. Here are the key differences between migraines and headaches:


  • Generalized Pain: Headaches typically cause more generalized pain and spread over the entire head. The pain is often described as an aching and dull sensation.
  • Duration: Headaches can be short-lived or chronic, lasting from a few minutes to several days. Most headaches are not associated with auras or other neurological symptoms.
  • Severity: While headaches can be painful, they are generally less intense than migraines. They usually do not cause nausea or vomiting.
  • Triggers: Common triggers for headaches include stress, tension, lack of sleep, dehydration, and certain foods or drinks.


  • Throbbing Pain: Migraines are throbbing or pulsating pain, often on one side of the head. The pain can be moderate to severe.
  • Duration: Migraines typically last longer than regular headaches, lasting from a few hours to several days. Some people experience a premonitory phase (prodrome) before the headache, which may include mood changes or other symptoms.
  • Associated Symptoms: Migraines are often accompanied by vomiting, nausea, sensitivity to light (photophobia), and sensitivity to sound (phonophobia). Some people also experience auras and visual or sensory disturbances that can precede the headache.
  • Triggers: Migraine triggers can include hormonal changes, certain foods and drinks (such as chocolate, alcohol, and caffeine), stress, lack of sleep, and environmental factors.

Migraines and headaches can coexist, and individuals may experience both conditions at different times. Additionally, chronic migraines are a specific subtype of migraines characterized by headaches occurring on 15 or more days per month for at least three months. On at least eight days, the headaches meet the criteria for migraines.

How can migraines and headaches affect one’s well-being? 

Migraines and headaches can significantly impact an individual’s overall well-being, affecting various aspects of their life. The consequences can be physical, emotional, and social. 

  • Physical Impact:
    • Pain and Discomfort: The pain associated with migraines and headaches can be intense and debilitating, affecting the ability to perform daily activities.
    • Nausea and Vomiting: Migraines, in particular, are often accompanied by nausea and vomiting, leading to additional physical discomfort.
  • Emotional Impact:
    • Stress and Anxiety: The unpredictability of migraines and headaches can lead to stress and anxiety. The fear of an impending headache or migraine may contribute to emotional distress.
    • Mood Changes: Migraines, especially those with auras, can be associated with mood changes. Some people experience irritability, depression, or heightened emotional sensitivity during or before a migraine.
  • Cognitive Impact:
    • Difficulty Concentrating: The pain and other symptoms associated with migraines and headaches can make it challenging to concentrate on tasks, affecting work or academic performance.
    • Cognitive Impairment: Some individuals may experience cognitive impairment during migraines, including difficulty thinking clearly or processing information.
  • Quality of Life:
    • Limitations on Activities: Migraines and headaches may lead to the avoidance of certain activities, including social events and physical exercise, reducing overall quality of life.
    • Impact on Sleep: Sleep disturbances are common with migraines and headaches, and poor sleep can exacerbate the frequency and severity of episodes.
  • Social Impact:
    • Social Isolation: Individuals with migraines or chronic headaches may withdraw from social activities to avoid triggers or because of the pain, leading to social isolation.
    • Impact on Relationships: The chronic nature of migraines can strain relationships due to the unpredictability and impact on daily life.
  • Work and Productivity:
    • Absenteeism: Migraines and headaches can lead to missed days at work or school due to the inability to function effectively.
    • Reduced Productivity: Even when present, individuals may experience reduced productivity during a migraine or headache episode.
