Seasickness, the unique form of motion sickness experienced while traveling on water, can quickly transform an enjoyable voyage into a miserable ordeal. This common affliction, marked by waves of nausea, dizziness, and vomiting, affects many travelers. Amidst the search for natural remedies, a popular, long-standing folk remedy suggests that the simple green apple can provide much-needed relief from the churning discomfort of a rough sea.
Understanding Motion Sickness
The underlying cause of seasickness is a physiological response rooted in “sensory conflict.” This conflict arises when the brain receives contradictory signals regarding the body’s movement and spatial orientation. The inner ear’s vestibular system detects the motion of the boat, including pitch, roll, and heave. Simultaneously, the eyes may be focused on a seemingly stationary interior, such as a cabin or a book.
This mismatch confuses the central nervous system. The brain, unable to reconcile the conflicting data from these two primary sensory inputs, triggers a stress response that manifests as the symptoms of motion sickness. The resulting neural signals traverse to centers in the brain that mediate nausea and vomiting.
The Specific Role of Green Apples
The idea that green apples help with seasickness is based on digestive and sensory principles rather than extensive clinical studies. The fruit’s proposed effectiveness focuses on its ability to settle the stomach, which is often severely upset during motion sickness. Green apples are particularly rich in pectin, a soluble fiber.
When ingested, pectin forms a gel-like substance in the digestive tract. This helps absorb excess stomach acid and stabilize gastric contents, acting as a mild antacid and bulking agent. The high fiber content also helps slow down the digestive process, keeping the stomach gently occupied.
Additionally, the sensory characteristics of the apple may contribute to relief. Green apples have a strong, sharp, and tart aroma that acts as a powerful sensory distraction. The crisp, clean scent and taste can temporarily cut through the feeling of sickness, which is often exacerbated by stale air or other odors. This sensory input helps redirect focus away from internal discomfort.
Other Effective Non-Pharmaceutical Relief Methods
While green apples offer a simple, palatable solution, several other non-pharmaceutical methods exist to manage or prevent seasickness. Ginger has strong scientific backing as a natural anti-nausea agent, working on the gastrointestinal tract to calm stomach contractions that precede vomiting. The active compounds in ginger, gingerols and shogaols, may interact with serotonin receptors in the gut, reducing the signals that trigger nausea.
One of the most effective behavioral countermeasures is focusing on a fixed point on the horizon. Gazing outward at the point where the sea meets the sky allows the visual system to confirm the movement sensed by the inner ear. This action helps reduce the sensory conflict in the brain, lessening the severity of symptoms. Seeking out fresh air and opting for a mid-ship position, which experiences the least amount of pitch and roll motion, can also provide relief.
Proper hydration and mindful eating are important preventative steps. Avoiding heavy, greasy, or spicy meals reduces the stomach’s workload, while sipping water prevents the dehydration often caused by vomiting. Acupressure wristbands, which apply continuous pressure to a point on the inner wrist, are another common non-drug option, although the evidence for their effectiveness remains mixed.
