It's time to stop blaming your headache for external agents, the reality is that many times the real cause is your lack of hydration.
People who do not hydrate properly, not only are exposed to problems with the kidneys, but may also have intestinal and circulatory problems.
Even if you find it difficult to relate it, when you do not consume enough water, the headache becomes present. Because your brain and eyes are not hydrating properly.
The lack of hydration in these organs causes severe inflammation in the internal and posterior parts of the eyes, which also causes you to see blurry.
The symptoms of severe dehydration translate into cramps, fatigue and tiredness; strong muscular pains and drastic mood swings.
