Effects of Anxiety on Physical Health

Anxiety not only affects your emotions but also triggers physical responses. It makes your muscles tense up, your heart race, and your breathing quickens. It also diverts blood away from your stomach to your brain.

When anxiety becomes chronic, these physical effects can intensify, causing symptoms like feeling lightheaded, stomachaches, and a consistently high heart rate.

Here are some ways anxiety affects the body:

Digestive Issues

Anxiety can lead to stomachaches, digestive problems, and conditions like irritable bowel syndrome (IBS). This is because anxiety affects the nervous system, which in turn influences your digestion.

Heart Problems

Ongoing anxiety can increase the risk of heart disease and other heart-related issues like rapid heart rate, high blood pressure, and decreased heart rate variability.

Breathing Trouble

Anxiety and breathing problems, like asthma, are closely connected. Anxiety can lead to rapid, shallow breathing, and worsen asthma symptoms. This can create a cycle of worsening symptoms.


Anxiety can also increase your risk of stroke. This is because it can damage your blood vessels and increase your risk of blood clots. Anxiety can also lead to high blood pressure, which is another risk factor for stroke.


This disease can increase your risk of diabetes by interfering with your body’s ability to regulate blood sugar levels. It can also lead to unhealthy lifestyle choices, such as overeating and underexercising, which can increase your risk of developing diabetes.

Weakened Immune System

Depression can weaken your immune system, making you more susceptible to infections and other illnesses. This is because depression can interfere with the production of white blood cells, which are responsible for fighting off infection.

Effects of Depression on Physical Health

Depression can lead to health problems like obesity, chronic pain, and sleep troubles. It can affect how you feel, think, and go about your daily tasks.

Obesity and Weight Gain

People with depression are more likely to be obese. This is because depression can lead to unhealthy lifestyle choices, such as overeating and underexercising. It can also cause sleep problems, which can also lead to weight gain.

Chronic Pain

Many people with depression experience chronic pain, which can include headaches, back pain, and more. Depression and pain often go hand in hand.

Insomnia and Sleep Issues

Depression is often associated with difficulty sleeping or staying asleep. This can further worsen mental health.
