If you suffer from seasickness while aboard a boat, it can be extremely unpleasant and sometimes debilitating. In severe cases it can even affect safety on board. Fortunately, several seasickness remedies may help prevent or reduce the symptoms.
Early signs that you may be about to succumb include pale skin, cold sweats, dizziness, yawning, increased saliva production (which leads to frequent swallowing), and eventually vomiting.
Here are some seasickness remedies that may help guard against this uncomfortable predicament.
Seasickness Remedies: Tablets
Several types of medication can help prevent seasickness.
Tablets containing hyoscine hydrobromide (also known as scopolamine) are widely used and can be very effective. These need to be taken before the journey starts, as once nausea begins the body may absorb medication less effectively.
Another option sometimes used for motion sickness is meclizine, available in some countries and commonly used by divers and sailors. Many people find it effective with relatively mild side effects.
However, motion sickness medications can have contraindications and side effects, including drowsiness. Always read the information leaflet carefully and speak to a pharmacist or doctor if you are unsure whether a medication is suitable for you.
Seasickness Remedies: Antihistamine Tablets
Some antihistamine tablets can also help with motion sickness. While many are normally taken for allergies, certain types (such as dimenhydrinate or meclizine) can reduce nausea and vomiting.
They may not completely prevent seasickness, but they can sometimes make symptoms more manageable.
As with any medication, check the patient information leaflet for guidance and potential side effects. Drowsiness is common with some antihistamines, so consider this before taking them while on board.
Seasickness Remedies: Patches
Prescription motion sickness patches are another option.
These patches usually contain hyoscine (scopolamine) and are placed behind the ear several hours before travel. The medication is slowly released through the skin and into the bloodstream to help prevent nausea.
As with other medications, check for possible side effects and consult a healthcare professional if needed.
Seasickness Remedies: Self-Care Tips
Medication isn’t the only way to deal with seasickness. Some simple measures can often help reduce symptoms.
- Look at a fixed point, such as the horizon. This helps your brain reconcile the motion your body feels with what your eyes see.
- If you are below deck, try to move outside where you can see the horizon.
- Sit near the middle of the boat, where movement is usually less noticeable.
- Get some fresh air and try to stay cool.
- Take the helm if possible. Concentrating on steering and watching the water ahead can help reduce nausea, and many sailors find it surprisingly effective.
These simple steps have saved many sailors from “feeding the fish”.
Final Thoughts on Seasickness Remedies
Seasickness affects people differently, and what works well for one person may not work as well for another. Trying different seasickness remedies, from medication to simple behavioural techniques, can help you discover what works best for you.
If you know you are prone to motion sickness, planning ahead before your trip can make a big difference to how much you enjoy your time on the water.
