Seasickness, also known as seasickness or motion sickness, is a common and unpleasant experience for many travelers. Despite advances in boat and boat technology, the constant rocking of the water can trigger symptoms such as nausea, vomiting, fatigue and dizziness. Finding the best cure for seasickness at sea has been the subject of study by sailors and scientists.
What are the causes of dizziness at sea?
Seasickness occurs when there is a conflict between the signals the brain receives from different sensory systems in the body. While the eyes may indicate that the environment is relatively calm (inside the boat), the inner ear, responsible for balance, detects the continuous movement of the waves. This discrepancy between visual perception and the vestibular system generates the symptoms of dizziness.
In addition to this sensory conflict, factors such as anxiety, tiredness and general physical condition can increase susceptibility to motion sickness at sea.
The best solutions against seasickness
While there is no one-size-fits-all cure, several strategies and treatments have proven to be highly effective. Here we present the best solutions to combat seasickness at sea, from natural remedies to clinically proven medicines.
1. Antiemetic drugs
One of the most effective and proven approaches to preventing and treating seasickness is the use of antiemetic drugs, which help control nausea and vomiting. Among the most popular are:
· Dimenhydrinate (Dramamine): This medicine is one of the most common against seasickness. It blocks receptors that cause nausea and helps stabilize the vestibular system. It is recommended to take it before boarding to prevent symptoms, although it may cause drowsiness.
· Meclizine (Bonine): Another popular drug, which has a longer action and less sedative effects than dimenhydrinate, making it ideal for long boat trips.
· Scopolamine (transdermal patch): This prescription medication is administered as a patch that is placed behind the ear. It works by blocking neurotransmitters that transmit dizziness signals to the brain. Its effect can last up to 72 hours, making it a convenient option for cruises or extended trips.
2. Visual stabilization techniques
The brain receives many of its balance signals through vision, so focusing your eyes on the horizon or a stationary object can help minimize the conflict between what your eyes see and what your inner ear perceives. Keep your gaze fixed on the horizon or to a stable point reduces the sensory imbalance, causing a significant decrease in symptoms.
3. Avoid reading or using mobile devices
Reading or using electronic devices while at sea can intensify the symptoms of seasickness. This is because while the eyes are focused on a stationary page or screen, the inner ear continues to perceive the movement of the waves. This decoupling between the senses is one of the main causes of seasickness, which is why it is advisable to avoid these activities during your trip.
4. Natural remedies
In addition to medications, some natural remedies have proven useful in relieving seasickness:
· Ginger: Ginger is one of the most popular natural remedies against seasickness. Its anti-inflammatory and antiemetic properties help calm the stomach. It can be consumed in capsules, sweets or ginger tea before or during travel.
· Mint: Peppermint, in tea or essential oil form, is known to relieve symptoms of nausea. Inhaling the aroma of mint or drinking an infusion can calm the stomach and help reduce dizziness.
5. Pressure bracelets (acupressure)
Outside of scientific recommendations there are acupressure bracelets, such as e.g Maritime Bandwhich use pressure points on the wrist to relieve nausea and discomfort. These bracelets require no medications and are a non-invasive option, especially useful for those trying to avoid medications. They work by applying pressure to the acupuncture point Neiguan (P6)which is associated with reduction of nausea.
6. Strategic position on the ship
Where you are on the boat can make a big difference in the severity of your symptoms. In general, it is recommended to be on the central of the boat, since it is the area least affected by rolling. Furthermore, if possible, being outdoors and breathing fresh air helps reduce the feeling of claustrophobia and improves general well-being.
7. Maintain good hydration and nutrition
Stomach pain associated with seasickness can worsen if the stomach is empty or if the body is dehydrated. It is advisable to maintain a light diet before boarding and during the trip, avoiding fatty or spicy foods. Consume small amounts of soft foods such as crackers or toast can help stabilize the stomach.
Emerging innovations and therapies
Science and technology continue to seek innovative solutions to seasickness. One of the most recent is the use of virtual reality (VR) to treat motion sickness. Some research suggests that using VR glasses that adjust visual signals in real time can reprogram the brain to reduce motion sickness symptoms, although this is still in experimental stages.
Another promising area of research is the use of vestibular stimulation. These devices, which stimulate the inner ear with small electrical currents, can help regulate the signals the brain receives about movement, thus reducing symptoms.
