22 Unexpected Physical Symptoms Caused by Chronic Stress
17. Increased Sensitivity to Sound or Light

Finding everyday noises gratingly loud or bright lights unusually harsh? Heightened sensory sensitivity can be a subtle yet significant physical symptom of chronic stress. When your nervous system is in a prolonged state of high alert (the "fight-or-flight" response), your senses can become overstimulated and more easily overwhelmed. This can manifest as photophobia (light sensitivity) or hyperacusis (sound sensitivity), making ordinary environments feel intense and draining. Addressing the root stress can help recalibrate your sensory processing and restore a sense of calm in your surroundings.
