Why can walking in the dark suddenly feel so much harder? 🌙
Your brain normally combines information from your vision, vestibular system and proprioception to maintain balance. When visual cues become less available in darkness, your other balance systems have to do more of the work.
This can be especially challenging for people with bilateral vestibular hypofunction (BVH), where vestibular function is reduced on both sides and the brain may rely more heavily on vision and proprioception to compensate.
