Yes, you can get claustrophobia on cruise ships, as cruise ships can be small and confining. Claustrophobia is the fear of closed spaces. It is also associated with the fear of being restricted or the fear of suffocation. On a cruise ship, there are many closed and confined spaces, and it is often crowded with people, which further adds to your feeling of suffocation.
To reduce your claustrophobia on cruise ships, try walking at regular intervals in open spaces, away from the crowds, and take in the fresh ocean air.
