What Is Seasickness & How To Deal With It?

What Is Seasickness?

Seasickness is a type of motion sickness, which hits mostly any person while at sea. It occurs as the motion perceived by the vestibular system does not match with the motion perceived visually. This leads to nausea, fatigue, and dizziness.

Though seasickness is most common amongst the first time traveler, even the most seasoned mariners fall prey to it. The problem is related to motion therefore when the motion stops the patient gradually comes back to normal.

What Causes Seasickness?

Seasickness occurs due to an imbalance in the sensory system. Its occurrence has three reasons.

  1. The motion is felt but not seen
  2. The motion is seen but not felt
  3. Both the above problems occurring simultaneously

Human balance mechanism resides in the inner ear, therefore seasickness known to be a result of the conflict in the inner ear. The conflict is caused by the vessels erratic motion on water. The inner ear detects the changes in the up-and-down and side-to-side acceleration as the body moves along with the boat. But since in the cabin, the eyes visualize a stable scene. Due to this incompatibility of the two senses, the brain responds with a cascade of stress hormone which ultimately leads to nausea, vertigo, and vomiting.

  • Moreover many times a person’s symptoms might be magnified by strong odors such as fumes and fishes.
  • A person can also feel sick on watching other passengers getting sick.
