Travel sickness, also known as motion sickness, is a common condition that affects many individuals during various modes of transportation.
It is characterized by symptoms such as nausea, dizziness, and vomiting, which occur when the brain receives conflicting signals from the eyes, inner ears, and other sensory receptors.
While travel sickness is often associated with discomfort and inconvenience, some individuals have wondered if there is a potential upside to this condition.
Specifically, can travel sickness lower blood pressure?
In this article, we will explore the relationship between travel sickness and blood pressure levels to shed light on this intriguing question.

Understanding Travel Sickness
Before we explore the potential effects of travel sickness on blood pressure, it’s essential to understand what happens during a bout of motion sickness.
Travel sickness occurs when there is a discrepancy between the information received by different sensory systems in our body.
Visual System: Our eyes send signals to our brain about our surroundings and the movement we perceive.
Vestibular System: The inner ear is responsible for detecting changes in motion and balance.
Proprioceptive System: This system provides information about the body’s position in space through receptors in muscles and joints.
During travel sickness, these systems send conflicting signals to the brain.
For example, when you are inside a moving car and reading a book, your eyes are focused on the book (perceiving stillness), while your inner ear and proprioceptive system are detecting the vehicle’s motion.
This sensory mismatch leads to symptoms like nausea and dizziness.
The Connection Between Travel Sickness and Blood Pressure:
Travel sickness is primarily associated with symptoms related to the gastrointestinal system and the vestibular system. However, there is limited evidence to suggest that it might also have an impact on blood pressure. Here are some factors to consider:
Autonomic Nervous System Activation: Motion sickness triggers an increase in sympathetic nervous system activity, commonly known as the “fight or flight” response. This can lead to an increase in heart rate and, in some cases, a temporary rise in blood pressure. This is often referred to as “sick sinus syndrome.”
Individual Variability: People react differently to motion sickness. Some may experience a transient increase in blood pressure, while others may not see significant changes.
Recovery Phase: Once the motion sickness subsides, blood pressure tends to return to baseline levels. Therefore, any increase in blood pressure is usually temporary.
Pre-existing Conditions: Individuals with pre-existing blood pressure issues may be more susceptible to experiencing significant fluctuations in blood pressure during motion sickness episodes.
Medication Effects: Some individuals may use medication to manage motion sickness (e.g., antiemetic drugs). These medications can have various effects on blood pressure, and their use should be discussed with a healthcare provider.
While travel sickness primarily affects the gastrointestinal and vestibular systems, there is evidence to suggest that it can temporarily increase blood pressure due to activation of the sympathetic nervous system.
However, the impact on blood pressure is generally short-lived, and once the motion sickness subsides, blood pressure tends to return to baseline levels.
It’s important to note that the effects of travel sickness on blood pressure can vary from person to person, and individuals with underlying cardiovascular conditions should be cautious when traveling.
If you experience severe motion sickness or have concerns about how it may affect your blood pressure, it is advisable to consult a healthcare professional for guidance on managing your symptoms and any potential blood pressure fluctuations during travel.
What is travel sickness, and what causes it?
Travel sickness, also known as motion sickness, is a condition characterized by symptoms such as nausea, dizziness, and vomiting during travel. It occurs due to a sensory conflict between different systems in the body, primarily the visual, vestibular (inner ear), and proprioceptive systems.
Can travel sickness lower blood pressure?
Travel sickness primarily activates the sympathetic nervous system, which can temporarily increase blood pressure. However, the impact on blood pressure is generally short-lived and tends to return to baseline levels once motion sickness subsides.
Do anti-motion sickness medications affect blood pressure?
Some antiemetic drugs used to manage motion sickness may have potential effects on blood pressure. It is advisable to consult with a healthcare provider before using such medications, especially if you have underlying blood pressure issues.
Can motion sickness worsen existing high blood pressure (hypertension)?
While motion sickness can temporarily raise blood pressure due to sympathetic nervous system activation, it is unlikely to worsen existing hypertension significantly. However, individuals with hypertension should take precautions and consult their healthcare provider before traveling.
Can travel sickness be completely prevented?
While travel sickness cannot always be entirely prevented, various strategies and medications are available to alleviate symptoms and make travel more comfortable for individuals who are prone to motion sickness. These methods should be discussed with a healthcare professional.
Is it safe to travel if I have a history of motion sickness and high blood pressure?
Traveling with motion sickness and high blood pressure can be safe with proper precautions. Consult your healthcare provider to discuss your specific situation, receive guidance on managing both conditions during travel, and determine if any adjustments to your treatment plan are necessary.
