Struggling From Recurrent Headaches, Here's How Drinking Water May Help

Recurrent headaches are a common complaint across age groups and lifestyles. These may interfere with work, mood, decrease concentration and alter the quality of life. Although stress, inadequate sleep, screen time, and dietary deficiencies can be the primary causes, headaches can also be attributed to something as simple as dehydration. 

Health experts warn that poor water intake may contribute greatly to having frequent headaches. So, we reached out to our expert, Edwina Raj, Head of Services - Clinical Nutrition & Dietetics, Aster CMI Hospital, Bangalore, and she explained that the problem with fluid balance is something that many people do not realise. The human body is delicate, particularly the brain. “Small degrees of dehydration may cause noticeable signs and symptoms and one of the most common ones is headache,” she said. Read ahead to know everything she shared with us,.

Importance of Water for the Brain

The brain consists of almost 75 percent water and it requires proper hydration to operate effectively. The fact that the body fails to receive sufficient fluids may lead to the shrinking of the brain tissue for a short time. This slight shrinkage can cause tension on nerves and its surroundings, which may result in discomfort and pain leading to a headache.

“Since this process is internal and invisible, people often miss the link between low water intake and recurring head pain,” Edwina said.

How Hydration Supports Healthy Blood Flow and Oxygen Supply

Proper blood circulation  is important for hydration. “When you are well hydrated, circulation remains stable and oxygen delivery to the brain is more efficient. Dehydration may decrease the amount of blood and oxygen carried in the blood which in turn may lead to headaches, tiredness, and lack of clear thinking,” she said.

According to Edwina, many people who experience recurring headaches feel better when their daily practices of hydration and other lifestyle interventions are corrected.

Role of Electrolyte Balance for Headaches

Water helps regulate electrolytes such as sodium and potassium, which are important for nerve signaling and muscle function. The imbalances in the electrolytes triggered by the lack of fluid consumption may cause the following symptoms: 

• Headaches
• Weakness
• Brain fogs

“These occur particularly in individuals who perspire a lot, engage in physical activities without the appropriate fluid intake or those who imbibe too many liquids with dehydrating effects such as too much caffeine.

Hydration Helps the Body Flush Out Waste

Proper hydration supports the body’s natural detox processes. Throughout the day, metabolic activities generate waste products that must be eliminated. Adequate water helps in proper functioning of the kidneys and in flushing out the toxins through the urine.

However, during low hydration, the process becomes less efficient which may lead to feeling heavy, and fatigued, eventually leading to a headache. Hence, regular consumption of water contributes to the maintenance of the internal balance and overall wellness.

“Skipping Meals and Low Water Intake Is A Double Trigger,” Said Edwina

“Lifestyle habits can further worsen dehydration-related headaches. People who fail to eat meals also forget to take sufficient water. Low sugar and low fluid intake are a twofold trigger of headaches,” said Edwina.

Unhealthy eating habits, stressful work schedules and high doses of caffeine may add to the effect. Regular water intake helps to keep the body going and might prevent tension-related headaches.

Does Water Help Reduce Migraines?

There is growing awareness that hydration plays a supportive role in migraine management. Although drinking water does not treat migraine, some migraine victims claim that the frequency or intensity of the condition reduces as long as they are well-hydrated.

Bottomline

Headache is not always struggling with complicated medical conditions, sometimes headache is triggered as easily as failure to drink enough water. According to experts, hydration promotes the volume of the brain, blood circulation, oxygen supply, and electrolyte equilibrium in the body. The habit of consuming water regularly is cheap and low-risk, and may be the best way to decrease the frequency and severity of headaches caused by dehydration.
