Can Dehydration Cause Stress?

Updated: Apr 20, 2023

Dehydration is a condition that occurs when there is an insufficient amount of water in the body. It can lead to a number of negative consequences, including stress. In fact, stress caused by dehydration is a very common problem.

One of the main ways that dehydration can cause stress is by increasing the levels of cortisol in the body. Cortisol is a hormone that is released in response to stress, and when levels are too high, it can lead to feelings of anxiety and tension.

Dehydration can also cause physical symptoms that contribute to stress, such as headaches, fatigue, and dizziness. These symptoms can make it difficult to focus on tasks and can also interfere with sleep, which can further exacerbate feelings of stress.

Another way that dehydration can contribute to stress is by affecting mood. Studies have shown that even mild dehydration can cause irritability, confusion, and a decrease in overall mood. This can make it difficult to manage stress and can lead to a negative spiral of stress and dehydration.

To avoid the stress caused by dehydration, it is important to make sure that you are drinking enough water throughout the day. The amount of water you need will vary depending on your activity level, but a good rule of thumb is to aim for at least 8 glasses (64 ounces) of water per day.

In addition to drinking enough water, it is also important to pay attention to other factors that can contribute to dehydration, such as excessive sweating or exposure to hot temperatures. By taking steps to stay hydrated, you can help prevent the negative effects of dehydration, including stress.
