The role of the cardiovascular system in the development of seasickness remains uncertain. Overall, 18 healthy students (10 males and 8 females) aged 18-24 years volunteered in the project, spending 2-7 h on life rafts. The cardiovascular system was examined with impedance cardiography. Susceptibility and symptoms of seasickness were evaluated by the (MSSQ-Short) and the (MSAQ). The (VAS), ranging 0-10, was used to assess nausea, dizziness and mood. The parameters were assessed at 2 time points. Differences in the heart rate (HR), the thoracic fluid content index (TFCI), the stroke index (SI) and the Heather index (HI) before launching the life rafts and after leaving them were observed (78.6, 20.8, 55.6 and 15.9 vs. 70.1, 19.7, 60.5 and 17.9, with p-values of 0.002,
