Can Dehydration Cause Anxiety? How to Boost Your Mood With Water
The body is made up of 60% water in adults (75% in children), so it stands to reason that not consuming sufficient water can negatively impact mental health and physical health. Research shows there is a potential correlation between having low water intake and a higher risk of anxiety and depression. |*| Below, you’ll find symptoms that can signify dehydration as well as ways to incorporate more water into your daily routine.

Dehydration and Anxiety
Several studies have been conducted to investigate the effect of water consumption on the human body. Their results showed that drinking higher quantities of water had a positive impact on anxiety disorders and depression.
For example, a 2018 study asked adults about their mood and how they felt after drinking plain water. Those who drank two cups of water or less daily had a significantly higher risk of depression than those who drank over five cups per day. |*|
Even just mild dehydration can cause a noticeable difference in mood. According to this study, healthy young women who had a 1% decrease in water showed symptoms of problems with concentration, headaches, and fatigue. |*|

Mental Symptoms of Dehydration
Dehydration rarely occurs without presenting symptoms, even with mild dehydration. The list below can help you identify if you’re potentially dehydrated. You can use the list below to increase water intake during the day and ultimately help your body and mind function properly.
According to the Mayo Clinic |*|, the following mental symptoms can occur due to dehydration:
· Feeling light-headed
· Mental health issues (like anxiety and depression)
· Feeling ill-tempered/having a short fuse
As a note, these symptoms are not always caused by dehydration and should be monitored as they may have a different underlying cause. As always, it’s important to work with your doctor to ensure you have the correct diagnosis. However, it does not hurt to drink a glass or two of water to see if it helps decrease the above symptoms.

The Mind-Body Connection
While dehydration can directly impact mood, it’s also necessary to consider how it takes a toll on the mind-body connection. Mind-body connection relates to how the body and mind react to each other. |*| For example, when you’re in a state of stress, your heart rate increases.
When you don't consume enough water, it can negatively impact your cognitive abilities in the areas of memory, critical thinking, and attention. Studies have shown that these effects are seen in both mild and chronic dehydration. |*|
There is a connection between cognitive abilities and mental health, with better cognitive abilities typically signifying better mental health and fewer anxiety symptoms. There is also a potential increase in the correlation between mental health, physical health, and cognitive abilities as you get older. |*|
To put it simply, when dehydration occurs your mental health can decline relatively quickly.
Your Brain and Water
Since brain tissue is made of 75% water |*|, it’s necessary to consume the proper amount of water to keep your brain functioning correctly. While the brain does not absorb water directly, drinking water does increase blood flow which helps transport oxygen to the brain. |*|
A properly functioning brain equates to better mental health. Studies show a correlation between dehydration and increased cortisol, the stress hormone. Elevated cortisol levels can lead to additional health issues.

How to Boost Your Mood With Water
The quickest solution to being dehydrated is increasing your water intake. You can also consume various fruits and vegetables with a high water content to help increase hydration. According to WebMD, about 20% of daily water intake is through hydrating foods. |*|
Examples of hydrating foods include watermelon, cucumber, strawberries, cantaloupe, and peaches. While consuming produce alone is not sufficient to prevent dehydration, it is a great way to supplement your daily water intake.
Simply drinking water can help calm individuals, as water has natural calming properties. This is likely due to a decrease in symptoms associated with dehydration. |*|
How Much Water Do We Need?
According to the National Academies of Sciences, Engineering, and Medicine in the United States, the recommended water intake is:
125 oz. for men
91 oz. for women
Food provides roughly 20% of your daily water requirements. This indicates that women require approximately 73 ounces of water, while men require approximately 100 ounces.
