Stand or sit above deck where the horizon is visible to help balance the senses. Lying down below deck may actually prolong sea sickness or make symptoms worse. The fresh air on deck may also help alleviate nausea. Try to stay mid-ship to avoid the more drastic movement changes found at either end of a boat. Getting plenty of rest before traveling is advisable, as fatigue may aggravate symptoms. Some people find that using an earplug in one ear helps regulate equilibrium and reduces sea sickness.
Use herbal remedies via taste and smell to alleviate sea sickness. Chamomile or lavender aromatherapy or essential oils have a calming effect and help digestion. Ginger, lemon and peppermint are also good for sea sickness and may be taken orally. Ginger is usually found in pill or powder form while sucking on lemon and peppermint hard candies can help relieve nausea.
Speak with a doctor about over-the-counter remedies or prescription strength drugs that can help with motion or sea sickness. Scopolamine patches may be prescribed to help with symptoms and even prevent sea sickness. Antihistamines are available over-the-counter and may also be used, but may cause excessive drowsiness on some people. For severe cases of sea sickness, sedating drugs that diminish sensory perception may be prescribed. Pregnant women and children should only be given medications for sea sickness under the supervision of a physician.
Avoid both overeating and an empty stomach. Dry crackers, bagels or other carbohydrates may help settle an upset stomach, while greasy, acidic or spicy foods often aggravate sea sickness. Drinking plenty of water both before and during boat trips will help prevent dehydration that may make the symptoms worse. Opt for water or clear carbonated beverages for hydration and to help settle an upset stomach. Avoid caffeinated or alcohol drinks as they may make dehydration worse.
Try alternative treatments such as pressure points or relaxation techniques. Acupressure bands made specifically for motion sickness may be purchased at most drug stores and help prevent sea sickness by applying continuous pressure to certain points on the wrist. Alternatively, gently squeezing on the webbed portion of the hand between the thumb and index finger may relieve nausea symptoms. Deep breathing techniques and meditation may also offer relief from and lessen the length of sea sickness.
