If you have ever boarded a long-distance bus at Ojota Motor Park in Lagos, or settled into a packed matatu in Nairobi, you probably know the feeling. The road bends, the vehicle sways, and within the first hour your stomach is lurching and your skin feels clammy. Motion sickness is one of the most common complaints among travellers worldwide. According to Medscape’s epidemiological review, nearly everyone will experience it at some point if the triggering motion is strong enough, with reported prevalence in travel settings ranging from around 3% to over 60% depending on conditions.
For millions of Africans who depend on shared minibuses, long-haul buses, and ferries as their primary mode of transport, motion sickness is not an occasional inconvenience. It is a recurring fact of life. This guide explains what causes it, why African road travel raises the risk, and what you can do about it before you board and during the journey.
What exactly is motion sickness?
Motion sickness happens when your brain receives conflicting signals from your senses at the same time. Your inner ears detect movement, but your eyes may be fixed on something stationary – a phone screen, a book, or the seat in front of you. Your body’s position sensors send their own separate reading. When these three systems cannot agree, your brain cannot reconcile the mismatch.
The CDC’s 2024 Yellow Book on travel health describes this as “sensory conflict theory,” the most widely accepted explanation for the condition. The brain interprets the disagreement as a potential threat and triggers nausea as a protective response. Medications that treat motion sickness work by suppressing the signals that produce this neural mismatch.
Who gets motion sickness most?
Children between the ages of two and twelve are the most commonly affected group. Very young infants are largely immune. Susceptibility tends to rise through early childhood, peak around age twelve, and gradually ease in adulthood.
Women are more affected than men. Hormonal shifts during menstruation, pregnancy, or while taking oral contraceptives can raise susceptibility further. People with a history of migraine are also notably more prone to motion sickness, and there is a well-documented clinical overlap between the two conditions. Treating migraines often reduces travel sickness in people who suffer from both.
Symptoms to watch for
Motion sickness usually builds gradually. Common symptoms include:
- Nausea and excessive saliva production
- Dizziness and a feeling of general unsteadiness
- Cold sweats and pallor (pale, clammy skin)
- Headache
- Loss of appetite
- Vomiting in more severe cases
Acting at the first sign of nausea – before symptoms peak – gives you the best chance of managing the episode.
Why African road travel makes things worse
Certain conditions common to road travel across sub-Saharan Africa raise the risk of motion sickness substantially. A 2022 study published in the Journal of Environmental and Public Health, based on 384 bus passengers in North Shewa Zone, Oromia, Ethiopia, identified four major modifiable risk factors. Passengers in overcrowded vehicles were nearly ten times more likely to experience nausea and vomiting. Sleep deprivation before travel, eating heavy meals such as fried eggs or roasted meat before boarding, and erratic or aggressive driving all raised the odds considerably.
Road quality compounds the problem. Research cited in PubMed shows that the type of motion most likely to trigger nausea is low-frequency lateral oscillation – precisely the kind produced by potholes, speed bumps, and unpaved surfaces. Passengers who could not see the road ahead were roughly three times more likely to feel ill than those with a clear forward view. These are features of everyday travel in Nigeria, Ghana, and across the continent.
What to do before you board
Prevention consistently outperforms treatment. If you are prone to motion sickness, take these steps before your journey:
- Sleep well the night before. Fatigue reliably worsens symptoms.
- Eat a light meal. Avoid heavy, fatty, or spicy foods in the two to three hours before travel.
- Choose your seat wisely. The front seat of a car or bus reduces motion perception. On a boat, the middle of the vessel is most stable.
- Stay hydrated. Sip water and avoid alcohol and heavily caffeinated drinks.
- If you travel regularly and suffer badly, ask a pharmacist about preventive medication before departure, not after nausea has already started.
During the journey
Once moving, a few habits help:
- Fix your gaze on the horizon or a distant point ahead. Do not read or scroll through your phone.
- Let fresh air into the vehicle. An open window helps many people.
- Breathe slowly and steadily.
- If nausea starts, recline your seat and hold your head firmly against the headrest.
- On a long trip, ask the driver to stop periodically. Even five minutes standing on solid ground can reset the body’s signals.
Medications that work (and one common mistake)
Medication can make travel comfortable for people with moderate to severe motion sickness – but only if taken before symptoms arrive. By the time nausea peaks, most anti-motion-sickness drugs offer little relief.
The Pharmaceutical Journal of the Royal College of Pharmacy recommends matching the drug to journey length. Hyoscine (scopolamine) is the first-line option for short journeys up to four hours. Cinnarizine (sold as Stugeron in many Nigerian and Ghanaian pharmacies) suits medium-length journeys. For long overnight trips, promethazine (Phenergan) is the preferred option. It is a prescription medicine in Nigeria, so plan ahead.
One mistake many travellers make is reaching for non-drowsy antihistamines such as cetirizine or loratadine. These do not work for motion sickness. As the CDC Yellow Book explains, effective motion sickness drugs must cross the blood-brain barrier, and newer antihistamines are specifically designed not to do that. All effective options cause drowsiness, so do not take them if you need to drive. Pregnant women and parents managing symptoms in young children should consult a doctor or pharmacist first.
On natural remedies: ginger has some supporting clinical evidence as a mild antiemetic and is widely accessible across Africa. For mild symptoms, ginger tea or capsules before boarding may help. For moderate to severe motion sickness, do not rely on it alone.
When to see a doctor
Motion sickness during travel is almost always self-limiting and resolves once movement stops. If dizziness or nausea develops without a travel trigger, or comes with double vision, slurred speech, severe headache, or difficulty swallowing, seek medical attention promptly. StatPearls on NCBI notes that certain serious neurological conditions, including basilar artery occlusion, can initially present with dizziness and nausea that resembles ordinary travel sickness. If your symptoms feel different from your usual experience, do not dismiss them.
FREQUENTLY ASKED QUESTIONS
Can motion sickness go away permanently? For many people, symptoms improve with age and with repeated exposure to the motion that triggers them – a process called habituation. Frequent travellers often find that their symptoms ease over time. Susceptibility does not disappear entirely for everyone, however, and some adults remain consistently affected.
Is it safe to take motion sickness tablets during pregnancy? No medication should be taken during pregnancy without first speaking to a doctor or midwife. Promethazine is sometimes used for pregnancy-related nausea under medical supervision, but self-medicating is not advisable. For related reading, see our earlier guide on managing nausea and vomiting in early pregnancy.
Can children take motion sickness medication? Some antihistamines are used in children from age two, but doses differ from adults and certain medicines are unsuitable for young children. The CDC advises that scopolamine should not be given to children at all. Always consult a doctor or pharmacist before treating a child, and follow dosage guidance precisely.
Does ginger actually work? It may help with mild symptoms. Ginger acts on the gut rather than the brain, which means it avoids the sedating side effects of pharmaceutical options. Clinical evidence is promising but not yet definitive for travel-induced nausea specifically. For severe symptoms, combine it with other strategies or use appropriate medication on professional advice.
Why does reading in the car make motion sickness worse? Reading fixes your eyes on a stationary page while your inner ears register the movement of the vehicle. This sensory mismatch is precisely what triggers nausea. Audiobooks, music, or simply closing your eyes and resting are far better options on long journeys.
Motion sickness is one of the most common and least-discussed health challenges of everyday travel across sub-Saharan Africa, where road journeys are often long, roads can be punishing, and vehicles frequently crowded. With the right preparation – restful sleep, a light meal, a sensible seat, and where needed, the correct medication taken before boarding – most people can travel comfortably and arrive well. If you suffer badly on a regular basis, a brief conversation with a pharmacist before your next journey is a far better investment than reaching for tablets on the roadside once you are already unwell.
