How much water should you drink for migraines?
For migraine prevention, adequate hydration is crucial. Adults should drink 2 to 2.5 litres of water daily, as dehydration is one of the most common migraine triggers. Insufficient fluid intake affects blood circulation to the brain and can cause headaches within hours. Optimal hydration helps prevent migraine attacks and reduces the intensity of existing symptoms.
Why does drinking too little water cause migraine attacks?
Dehydration disrupts blood circulation to the brain and reduces blood volume, causing the brain to receive less oxygen and nutrients. This leads to the dilation of blood vessels and inflammatory reactions that activate migraine triggers.
When your body lacks fluid, it produces stress hormones such as cortisol and adrenaline. These hormones affect the neurotransmitters in your brain, including serotonin, which plays an important role in migraine development. Additionally, fluid deficiency causes your blood to thicken, further impeding circulation to the brain.
The process often begins with fluid loss of just 2% of your body weight. At that point, the first symptoms, such as migraine headaches, can already occur. The brain reacts extremely sensitively to changes in fluid balance, as it consists of 75% water.
How much water should you drink exactly to prevent migraine?
The recommended daily amount of water for migraine prevention is 35 millilitres per kilogram of body weight. For a 70-kilogram adult, this means approximately 2.5 litres per day. In hot temperatures, during exercise or stress, increase this by 500 to 750 millilitres extra.
Distribute your water intake evenly throughout the day by drinking a small glass every hour. This prevents sudden fluctuations in your fluid balance that can trigger migraine. Start your day with two glasses of water to replenish the fluid loss from the night.
Consider these factors that increase your fluid needs:
- Physical activity: 150 to 250 ml extra per hour of exercise
- Hot weather: 500 to 750 ml extra at temperatures above 25°C
- Stressful periods: 300 to 500 ml extra during busy days
- Caffeine consumption: 100 ml water per cup of coffee or tea
What signs indicate you’re drinking too little with migraine?
Early warning signs of dehydration that can precede aura spots and migraine include: dark urine, dry mouth, fatigue and mild headache. These symptoms often occur 2 to 4 hours before a full migraine attack begins.
Watch for these specific signs indicating fluid deficiency:
- Urine darker than light yellow
- Thirst, especially in the morning
- Dry lips and sticky saliva
- Concentration problems and irritability
- Dizziness when standing up
- Reduced skin elasticity
In migraine-sensitive people, these symptoms can quickly escalate to a full attack. You can distinguish from other types of migraine causes by checking whether symptoms diminish after drinking 2 to 3 glasses of water within 30 minutes.
What are the best drinks against migraine besides water?
Electrolyte drinks and herbal teas are effective alternatives to water for migraine prevention. Ginger tea reduces inflammation, chamomile tea relaxes blood vessels, and isotonic drinks restore the mineral balance important for nerve function.
Effective drinks for migraine prevention:
- Ginger tea: reduces inflammation and nausea
- Chamomile tea: relaxes muscles and blood vessels
- Coconut water: natural electrolytes without added sugars
- Diluted sports drinks: during heavy sweating or prolonged exercise
- Magnesium water: supports nerve and muscle function
Avoid these drinks that can worsen migraine: alcohol (increases dehydration), large amounts of caffeinated drinks, sugary soft drinks and energy drinks. These can cause blood sugar fluctuations that act as migraine triggers.

Frequently Asked Questions
How do I know if my migraine is really caused by dehydration or other causes?
Test this by drinking 2-3 glasses of water immediately within 30 minutes at the first signs of headache. If the pain diminishes within an hour, dehydration is likely the cause. Also keep a migraine and drinking diary to recognise patterns between your fluid intake and attacks.
Can I drink too much water and actually cause migraine?
Yes, overhydration can cause electrolyte imbalance which also triggers migraine. Don't drink more than 1 litre per hour and ensure adequate minerals by occasionally adding electrolyte drinks or a pinch of sea salt to your water. Listen to your body and drink when thirsty.
What should I do if I often forget to drink enough water?
Set an alarm on your phone every 2 hours, use a water app that tracks your progress, or place water bottles everywhere as visual reminders. Start every meal with a large glass of water and always drink a glass before and after using the toilet.
Does drinking water still help during a migraine attack?
Yes, even during an attack, hydration can reduce intensity and duration. Drink small sips of lukewarm water to prevent nausea, possibly add ginger or mint. Combine this with rest in a dark, quiet room for the best result.
Are there specific times when I should drink extra water?
Drink extra water when waking up (2 glasses), before and after exercise, during stress, hot weather, and if you've consumed alcohol or caffeine. Also before, during and after menstruation, women often need more fluid due to hormonal changes that can trigger migraine.
Why do I sometimes get headaches despite drinking enough water?
Migraine often has multiple triggers simultaneously. Check whether you're getting enough electrolytes, eating regularly, sleeping enough and managing stress. Certain foods, weather changes or hormonal fluctuations can also cause migraine despite good hydration.
