During dehydration, we struggle to get the chemicals required to produce serotonin into our brain. Being just half a litre dehydrated may also increase the stress hormone cortisol, which has been associated with a range of mental disorders, including anxiety. Water makes up 75% of brain tissue.
In one 2018 study of over 3,000 adults, those who drank more water had a lower risk of anxiety and depression than those who drank less water. Though the connection between dehydration and depression was stronger, researchers found that anxiety was higher in those who didn't drink enough water.
Another large study found people who drink five cups or more of water per day were at lower risk of depression and anxiety. In comparison, drinking less than two cups per day doubles the risk. This link was less noticeable for anxiety alone (although feelings of depression and anxiety often influence each other).
“Taking a moment to pause and drink a glass of water does two things,” she says. “First, it rehydrates us, which can help lower an accelerated heart rate due to even slight dehydration, and, second, it's like a mini mindfulness exercise.
Water triggers our parasympathetic nervous system
Water has a powerful physiological effect on your body – so much so that even drinking a glass of water can calm your nerves. This is because water triggers the parasympathetic nervous system, which is responsible for the body's 'rest and digest' response.
Water stimulates the flow of nutrients and hormones that release those feel-good endorphins you need to feel happy.
If you are dehydrated, your body is not functioning properly, and therefore may cause increased levels of stress. Studies have shown that even as little as a half liter of dehydration can bring your cortisol levels up. With high cortisol comes high stress!
Dehydration can sometimes cause feelings of anxiety, depression, and fatigue. To avoid dehydration, be sure to drink plenty of water and other fluids throughout the day. If you're feeling anxious and think you might be dehydrated, try drinking some water.
It involves looking around your environment to identify three objects and three sounds, then moving three body parts. Many people find this strategy helps focus and ground them when anxiety overwhelms them.
Alcohol is a depressant. It slows down processes in your brain and central nervous system, and can initially make you feel less inhibited. In the short-term, you might feel more relaxed - but these effects wear off quickly. In fact, if you're experiencing anxiety, drinking alcohol could be making things worse.
However, the knowledge regarding beneficial effects of water consumption in mental health is rare. Water facilitates signaling pathway and nutrients delivery to the brain, removes toxins and inflammatory markers and provides energy sources for brain, and thereby improves brain function.
Water plays a key role in how the body functions. It can help our bodies recover and heal from physical and emotional stressors. It does this by flushing cortisol (a stress hormone) from our systems, along with other toxins.
Anxiety can be caused by a variety of things: stress, genetics, brain chemistry, traumatic events, or environmental factors. Symptoms can be reduced with anti-anxiety medication. But even with medication, people may still experience some anxiety or even panic attacks.
Anxiety disorders are the most common of mental disorders and affect nearly 30% of adults at some point in their lives. But anxiety disorders are treatable and a number of effective treatments are available.
It is based on the three "C's" of recovery calm your body, correct your thinking, and confront your fears.
When you have it, you may feel: Cramping, churning, tightness, or knots in the stomach. “Butterflies” in the stomach feeling. Shivering, shaking, or twitching of muscles.
From the time of diagnosis, an anxiety disorder can last from a few months to many years. Most people will have symptoms of an anxiety disorder for a long time before seeking professional help, sometimes up to 15 years³.
Increasing water intake has beneficial effects in LOW, especially sleep/wake feelings, whereas decreasing water intake has detrimental effects on HIGH's mood. These deleterious effects in HIGH were observed in some sleep/wake moods as well as calmness, satisfaction and positive emotions.
When you are overhydrated, you may experience low blood sugar as the excess water in the body dilutes the blood's sugar (glucose) content. Low blood sugar may cause you to experience tremors, pallor, anxiety, increased heart rate, sweating, and palpitations, according to the Center for Disease Control and Prevention.
Dehydration also depletes the levels of other amino acids in your brain, leading to feelings of anxiety, dejection, irritability, and inadequacy. The third most common way dehydration can lead to depression is by increasing stress in your body.
Hyperhydration induced moderate increases in serotonin and 5-HIAA levels in the hypothalamus with no changes in the midbrain.
