Anxiety doesn’t only begin in the mind. There’s a constant communication happening between your brain and your gut, and it runs both ways. When your body is under-fuelled or low on hydration, that communication can start to falter. Hunger, undernourishment, or even mild dehydration can subtly affect the chemistry that helps regulate how calm or tense you feel—impacting hormones, stress signals, and neurotransmitters like serotonin. You might have felt this before as “butterflies” in your stomach when something feels uncertain or overwhelming—the mind can trigger that sensation.

When these basics are off, your system can feel less steady. It doesn’t create anxiety out of nowhere, but it can make it feel stronger, closer to the surface, and harder to ease. All of this is natural, part of how the body is designed to respond and protect—but when it’s out of balance, it can heighten what would otherwise be nothing more than a normal, passing concern.

Sometimes, the most helpful place to look isn’t deeper into your thoughts, but gently back toward your body. Have you eaten recently? Have you had enough water today? These are small things, but they shape how steady you feel. You don’t need to fix everything at once. A glass of water, something simple to eat, a moment to pause. Often, when the body is supported, the mind follows—quietly, and without effort.

If things are feeling off, it can help to gently build better daily habits.
