How does motion sickness affect scuba diving?

Scuba diving involves descending into the water, which can cause changes in pressure and temperature. These changes can affect your inner ear, which is responsible for maintaining your balance. If you have a history of motion sickness, you may be more susceptible to experiencing these symptoms while scuba diving.

What can I do to prevent motion sickness while scuba diving?

There are several things you can do to prevent motion sickness while scuba diving:

  • Take motion sickness medication: There are several over-the-counter medications that can help prevent motion sickness, such as Dramamine or Bonine. These medications work by blocking the signals to your brain that cause nausea and vomiting.
  • Avoid eating heavy meals before diving: Eating a heavy meal before diving can increase your risk of experiencing motion sickness. Stick to light, easy-to-digest foods before your dive.
  • Stay hydrated: Dehydration can worsen the symptoms of motion sickness. Make sure you drink plenty of water before and during your dive.
  • Choose the right dive site: Some dive sites are more prone to currents and waves, which can increase your risk of experiencing motion sickness. Choose a dive site that is calm and has good visibility.
