What Does Anxiety Do to Your Body?

When we think of anxiety, many people think about a state of worry and stress. While this is true in some ways, anxiety disorders go deeper than that and can have many different effects. People may experience the effects of anxiety differently and in different ways, which is why it can sometimes feel challenging to find the right type of support for you. While it’s important to understand what anxiety does to your mind and how you can help yourself to manage some of the effects of this, it’s also important to consider what anxiety does to your body. Here are some of the things to look out for if you or somebody you know is struggling with anxiety.

Increased perspiration

If you feel like you sweat more than the rest of your friends, it might be a result of an anxiety disorder. This is just one of the ways your body reacts to increased feelings of panic, stress or worry. Try to notice when you sweat more and look for patterns which could help you learn more about triggers for your anxiety.


Feeling tired and fatigue a lot of the time can be down to various health conditions, including hypothyroidism, diabetes, and anxiety. Sometimes a person may have a combination of several conditions which worsen their symptoms. However, if there is no other explanation for increased fatigue, it could be a result of anxiety.

Sleep problems

Common sleep problems such as insomnia are often seen in people who suffer from anxiety. A lack of sleep, or a lack of good quality sleep, can have many other effects on your body which then worsen the existing symptoms of anxiety. This could include fatigue, a lack of concentration, depression, irritability and increased stress levels due to excessive cortisol, also known as the stress hormone.


Headaches are very common in people with anxiety. Headaches can be caused by stress and tension, which is often increased when a person is anxious. Headaches can occur unexplained as a result of low-level persistent worrying. Headaches may also occur as a result of poor sleep or lack of sleep – another common bodily symptom of anxiety as mentioned above.


People suffering with anxiety disorders may find that they feel too hot even when the weather is cold, or they get hot flushes quicker and/or more often. Like many of the symptoms of anxiety, this can also be related to other health problems, so it’s important to speak to a doctor and eliminate other health conditions too.
