Many physical sensations feel worrying simply because they’re unfamiliar.
Things like twitching, dizziness, chest tightness, fatigue, palpitations, or strange internal sensations often appear without illness or injury — and then come and go without a clear reason.
Everyday Body Signals explains these common experiences in plain English.
You’ll find clear, non-alarmist explanations of what these sensations usually mean, why they appear when they do, and how to tell normal body signals from situations that are worth checking.
This site doesn’t diagnose or treat.
It exists to reduce unnecessary fear by making everyday bodily responses understandable.
Most of the time, these sensations reflect normal nervous system activity, stress, fatigue, breathing patterns, posture, or recovery — not disease.
Understanding what’s happening is often enough for the body to settle on its own.
