Seasickness stems from confusion between your vestibular (the balancing organ in your middle ear) and your visual sensations. "Our brain receives messages telling us we are not moving, but our eyes tell us otherwise," explains Dr Jonathan Cohen, medical director of Travel Clinics Australia (travelclinic.com.au).
To minimise this spatial disorientation, Cohen suggests limiting your head movements and focusing on an external object like a stable horizon. Avoid visual stimuli like reading or watching videos, and seek out a central spot on the boat where the rocking is less dramatic.
