Some of the world\u2019s best dive sites are accessible only by boat, and unfortunately seasickness prevents some scuba divers from visiting their dream destinations. Unmanaged seasickness will make any boat trip miserable, and if relief cannot be found the effects can pose a serious threat to a diver\u2019s health. Though there isn\u2019t a cure for seasickness, there are ways to prevent it and manage it.<\/p>\n\n\n\n
The word seasickness<\/em> is a bit of a misnomer because motion, not water, is what causes affected individuals to feel ill. In fact, many divers who feel dizzy or nauseated on a dive boat discover the symptoms of their motion sickness disappear as soon as they get in the water (or descend). Motion sickness can occur when traveling on a boat, flying in an airplane or riding in a car. The repeated motions associated with these modes of transportation can disturb the motion-sensing organs in our inner ears, and motion sickness develop when the brain receives conflicting signals from different sensory organs.<\/p>\n\n\n\n If a boat passenger inside a windowless cabin can feel the boat moving up and down in their muscles and joints, their inner ears are telling them to balance according to this perceived motion and their eyes see surroundings that appear to be stationary, this passenger may start experiencing dizziness, nausea and vomiting. Scientists are still unsure why vomiting is one of the body\u2019s reactions to these conflicting signals, but some hypothesize the body is reacting as if it has been poisoned and is attempting to purge toxins.<\/p>\n\n\n\n Given the right combination of motion stimuli and exposure time, anyone can experience motion sickness, but certain people are more susceptible. Women, children and those who suffer from migraine headaches are more likely to experience motion sickness.<\/p>\n\n\n\n Preventing seasickness is easier than treating it. Dehydration due to vomiting is a serious threat to divers who are prone to motion sickness, so if you are prone to it, take preventative measures before you feel unwell.<\/p>\n\n\n\n Anti-nausea medications such as Bonine (meclizine), Dramamine Less-Drowsy (meclizine), Dramamine (dimenhydrinate), Marezine (cyclizine), and Benadryl (diphenhydramine) work by suppressing nerve pathways between the control center in the brain that induces vomiting and other control centers. Drowsiness is a side effect of many of these medications, so experiment with them to test your susceptibility to drowsiness before using one of these medications while diving.<\/p>\n\n\n\n Some divers acquire a prescription for the scopolamine patch, which reduces nerve activity in the inner ear to prevent motion sickness. The patch releases the drug slowly through the skin; because scopolamine affects the central nervous system, its side effects can impair your ability to dive safely.<\/p>\n\n\n\n The most common side effects of scopolamine are dry mouth and blurred vision. Other side effects, more common in children and the elderly, include hallucinations, confusion, agitation and disorientation. Scopolamine can also cause problems for individuals with glaucoma or an enlarged prostate. Wearing a scopolamine patch for more than three days can bring on withdrawal symptoms that mimic symptoms of decompression sickness which can complicate proper diagnosis. If divers who wear the patch experience dizziness, nausea or vomiting within 24 hours of a dive, they should contact a physician.<\/p>\n\n\n\n Before taking any medication or trying a natural remedy in a diving setting, know how it affects you. On a day when you won\u2019t need to drive, operate heavy machinery or generally need your wits about you, take one dose and assess your condition. If you are unimpaired and pleased with the results, employ this method of seasickness prevention and book your next boat dive.<\/p>\n\n\n\nSeasickness Prevention<\/h3>\n\n\n\n
