Why would it help to look at the horizon while you are sea sick?

Looking at the horizon while feeling seasick can help stabilize your sense of balance and orientation. The horizon provides a fixed point that can reduce the sensory conflict between what your eyes see and what your inner ear feels, which is a common trigger for motion sickness. Focusing on a stable object can help recalibrate your brain's perception of motion, potentially alleviating nausea. Additionally, it encourages a sense of calm and connection to the environment, which can further ease discomfort.
