Show Know The Weather -What causes most of the seasickness experienced on ocean trips of some distance? ONE OF the secret causes of seasickness (which can be controlled to a considerable degree today by drugs) is swell. Unlike waves, swell cannot be detected by the novice of the sea. A swell is caused by a weather disturbance distur-bance and may radiate out for many, many miles. It causes boats, large and small, to dip or sway one way when the waves, or surface action of the water indicate an opposite reaction from the boat. The stomach muscles are "fooled" by this constant, unexpected motion. FINALLY ONE experiences what is really a nervous breakdown of the stomach muscles and gets seasick. One can get seasick without encountering swell, but it is probably the least understood of the sources of motion sickness. |
