The idiomatic expression "listen to your body" means paying attention to and respecting the physical sensations, signals or symptoms that your body is sending you. It suggests being in tune with how you feel both physically and emotionally, and responding appropriately by taking care of yourself when needed. This phrase can also refer to making healthy choices based on what your body tells you it needs - such as eating nutritious foods or getting enough rest- rather than ignoring its signals or pushing it beyond its limits.
