Motion sickness is a common condition that occurs when there's a conflict between the signals your brain receives from your inner ear, eyes, and other sensory organs. This sensory mismatch creates confusion in your brain's balance centre, leading to the unpleasant symptoms many Australians experience during travel.
The inner ear contains fluid-filled semicircular canals that detect movement and help maintain balance. When you're in a moving vehicle, your inner ear senses motion, but your eyes might see a stationary interior. This disconnect between what you feel and what you see triggers motion sickness. Your brain struggles to process these conflicting signals, resulting in nausea and other uncomfortable symptoms.
Common triggers for motion sickness include:
Typical symptoms include nausea, vomiting, dizziness, cold sweats, headaches, and general discomfort. Some people may also experience fatigue, drowsiness, or increased saliva production.
Certain groups are more susceptible to motion sickness. Children aged 2-12 years are particularly prone, as their balance systems are still developing. Pregnant women often experience heightened sensitivity due to hormonal changes. People with migraine disorders, inner ear problems, or anxiety conditions may also be more likely to develop motion sickness during travel.
Car sickness is the most common form of motion sickness experienced by Australians, particularly during long road trips or city driving. It typically occurs when passengers focus on reading or mobile devices while the vehicle is moving. Symptoms usually begin within minutes of travel and may intensify on winding roads or during frequent stops. Children in back seats are especially vulnerable as they have less visual contact with the horizon.
Seasickness affects many people travelling on boats, ferries, or cruise ships around Australia's extensive coastline. The constant rocking motion of vessels on water creates persistent sensory conflict. Symptoms can be more severe and longer-lasting than other forms of motion sickness, sometimes persisting for hours even after reaching shore. Rough seas and smaller vessels typically worsen symptoms.
Air travel motion sickness occurs during flights, particularly during turbulence, takeoff, and landing. The rapid changes in altitude and air pressure can intensify symptoms. Most people adapt quickly once the aircraft reaches cruising altitude, but sensitive individuals may experience discomfort throughout the flight.
Modern technology has introduced new forms of motion sickness from virtual reality headsets, video games, and large-screen movies. These create visual motion without corresponding physical movement, confusing the brain's balance system. Symptoms are typically milder but can include eye strain and headaches alongside traditional motion sickness symptoms.
Australian pharmacies stock a comprehensive range of motion sickness treatments, from over-the-counter solutions to prescription medications. Understanding your options helps you choose the most suitable treatment for your travel needs.
Several effective medications are readily available without prescription at Australian pharmacies:
For severe motion sickness or when over-the-counter options prove ineffective, your GP may prescribe stronger medications. Prescription hyoscine patches offer 72-hour protection and are particularly useful for cruise passengers. Consult your doctor if you experience persistent symptoms or have underlying health conditions that may interact with standard treatments.
Many Australians prefer natural remedies, with ginger supplements showing proven effectiveness in clinical studies. Acupressure bands, worn on the wrists, stimulate pressure points and provide drug-free relief. These options are safe for children and adults who cannot tolerate traditional medications.
Most motion sickness medications work best when taken 30-60 minutes before travel. Children under two years require special consideration, with many medications unsuitable for this age group. Always check product labels for age-specific dosing instructions, as children's dosages differ significantly from adult recommendations. Elderly passengers should consult pharmacists about potential interactions with existing medications before travelling.
Proper preparation can significantly reduce your risk of motion sickness. Get adequate sleep the night before travelling and avoid heavy meals within two hours of departure. If you're prone to motion sickness, consider taking preventive medication 30-60 minutes before travel begins, as directed by your pharmacist or healthcare professional.
Light, easily digestible foods work best before and during travel. Avoid alcohol, caffeine, and greasy foods. Choose your seating wisely: sit over the wing in aircraft, towards the front of buses, or on deck in ships. In cars, the front passenger seat is ideal. Keep your head still and focus on the horizon or a distant fixed point when possible.
Several non-medication approaches can help manage motion sickness:
Combining these strategies with appropriate medication often provides the most effective relief for motion sickness symptoms.
Most motion sickness medications can cause drowsiness, dry mouth, and blurred vision. Antihistamines like dimenhydrinate may also cause dizziness or difficulty concentrating. Scopolamine patches can cause skin irritation at the application site and should be applied behind the ear as directed.
Motion sickness medications may interact with other medicines, particularly those affecting the central nervous system. Avoid alcohol whilst taking these medications, as it can increase drowsiness and impair coordination. Many motion sickness treatments can significantly impair your ability to drive or operate machinery safely.
Children under two years should not use most motion sickness medications without medical supervision. Pregnant and breastfeeding women should consult their healthcare provider before taking any motion sickness treatments. Elderly patients may be more sensitive to side effects and require adjusted dosing. Always consult a healthcare professional if you have underlying medical conditions, take regular medications, or experience severe or persistent symptoms despite treatment.
Consider the duration and type of travel when selecting motion sickness treatment. Short trips may only require natural remedies or fast-acting medications, while longer journeys might benefit from sustained-release options. Your age, medical history, and other medications will influence which treatments are most suitable for you.
Many motion sickness treatments are available over-the-counter at competitive prices. Some prescription options may be covered under the Pharmaceutical Benefits Scheme (PBS) when medically necessary. Your local pharmacist can provide personalised advice on the most cost-effective and appropriate treatment options, helping you find the best solution for your specific travel needs and budget considerations.
