Staying above deck in the fresh air is a well-established method for helping to prevent motion sickness. When individuals are exposed to fresh air, it can alleviate the feeling of nausea and discomfort that often accompanies being in a confined space. The fresh air helps to alleviate feelings of dizziness or queasiness that result from the disorientation of being on a moving vessel. Moreover, being above deck allows individuals to see the horizon, which helps to reorient the senses and improve balance.

In contrast, remaining in confined spaces can exacerbate feelings of motion sickness, as it limits airflow and can create a stuffy environment. Focusing on the movement of the boat may also worsen symptoms, as it draws attention to the sensation of motion rather than helping to alleviate it. Smoking is not an effective strategy for preventing motion sickness and may even contribute to nausea in some individuals due to the inhalation of smoke and its effects on the body.
