The Link Between Dehydration And Depression

It’s no secret that drinking enough water every day is imperative to your best health. Drinking enough water regularly can help to keep your body hydrated, leading to weight maintenance and a healthy BMI, better sleep, and reduced stress, along with reduced risk of various health conditions. But did you know that drinking water can also be linked to lower risk of depression? In this article, we find out how drinking enough water every day can have a connection to your mental health.

Dehydration And Your Mental Health

Dehydration can lead to a range of health concerns and risks. Dehydration can occur when more water leaves the body than enters it. Even mild symptoms of dehydration can provide you with an indication that it’s time to fill your glass, such as headaches, dry mouth, lethargy, dizziness, and constipation.

Some studies have shown a link between dehydration and mental health, including but not limited to depression. In these studies, men and women were asked to perform light exercise, such as walking on a treadmill, with a diuretic pill. These pills encourage urination and can lead to dehydration. Following a series of tests that measured their concentration, memory and mood while hydrated and dehydrated, it was shown that they had an increase in their perception of task difficulty, lower concentration and experienced more fatigue.[i]

Every system relies on water to function properly, and the brain is no exception. Mental health can be driven and affected by the function of your brain, which relies on water. While mental health issues such as depression aren’t technically a direct result of dehydration, it can most definitely be affected by it, in at least three ways:

  • Reduced energy in the brain
  • Impeded serotonin production
  • Increased stress throughout the body [ii]

In general, drinking water is crucial to living a well-balanced and healthy lifestyle. This can contribute to your physical, emotional and mental health. It is encouraged that you drink 8-10 glasses of water a day, based on factors such as your climate, gender, height and weight, eat a well-balanced diet and engage in regular exercise.
