What could exacerbate the effects of seasickness?

Poor ventilation can significantly exacerbate the effects of seasickness. When a space is poorly ventilated, it can lead to the accumulation of stale air, unpleasant odors, or even the presence of carbon dioxide, all of which can trigger or worsen nausea and discomfort. Fresh, circulating air helps to alleviate feelings of seasickness by promoting a sense of well-being and reducing the chances of dizziness that can accompany nausea.

In contrast, deep breathing techniques are beneficial for calming the nervous system and helping to alleviate feelings of anxiety, which can accompany seasickness. Staying hydrated is crucial as dehydration can worsen overall physical discomfort, including nausea. Engaging in physical activity can also help in some instances, as it may distract from feelings of seasickness and allow for better acclimatization to the boat's motion. Thus, good ventilation is key in maintaining a comfortable environment aboard a boat and preventing the worsening of seasickness symptoms.
