Exploring the Connection Between Ataxia and Humidity Flare-Ups

Ataxia and Humidity - Michaelmantz ataxia Blogs3

Imagine a world where the simple act of walking, balancing, or coordinating your movements becomes a daily struggle.

Learning to live with a progressive condition is a harsh reality. As I get older, simple things that I used to take for granted are becoming more and more difficult. I know everyone with Ataxia and other movement disorders will tell you the same thing.

Recently, I have seen questions in different forums about this issue. I personally don’t have much experience with daily living in a humid climate since I have spent the last 10-15 years living in the Southwest. But there is a lot of information out there about the correlation. For those of you who do live in a humid climate, what are your thoughts?

While the causes of ataxia are diverse, ranging from genetic mutations to acquired conditions, there is an ongoing debate about whether environmental factors, particularly humidity, can trigger or worsen ataxia flare-ups. So, let’s take a further look into the complex relationship between humidity and ataxia.  Examining both scientific studies and personal experiences to shed some light on this subject.

Understanding Ataxia

It is critical to understand the fundamentals of ataxia before exploring the probable connection between this neurological disorder and humidity. A set of conditions known as ataxia are characterized by poor balance and coordination. These disorders can be generally categorized into two types: acquired ataxia and hereditary ataxia.

Acquired Ataxia: Acquired ataxia can result from various factors such as trauma, infections, poisons, or certain medical disorders like multiple sclerosis, among other things. 

Hereditary Ataxia:  On the other hand, hereditary ataxias are essentially genetic in nature and progress over time. They tend to get worse gradually and are brought on by mutations in particular genes.

The Symptoms of Ataxia

For the most part, Ataxia’s symptoms can include unsteady gait, clumsiness, slurred speech, and impaired fine motor skills. Most of us frequently struggle with routine tasks including walking, writing, and even eating. These symptoms can range in severity.

Given the complexity of the nervous system, identifying the exact causes and triggers of ataxia can be challenging. And that brings us to the subject of this article and the question of whether humidity can influence ataxia flare-ups.

Anecdotal Evidence: Humidity and Ataxia

Numerous people have claimed that changes in their symptoms have occurred in reaction to environmental conditions, particularly humidity. While anecdotal evidence is not a substitute for rigorous scientific research, it can provide valuable insights into the everyday experiences of those with ataxia.

Increased Symptom Severity: Some people with ataxia claim that their symptoms worsen during humid weather. They describe increased unsteadiness, difficulty walking, and more noticeable coordination problems.

Sensitivity to Temperature Changes: Individuals with Ataxia have also reported sensitivity to temperature changes that often accompany high humidity. This sensitivity might lead to increased discomfort and aggravation of their symptoms.

Impact on Fatigue Levels: Humidity can make all of us feel more fatigued. This can be especially challenging for people with ataxia, as fatigue is a common symptom of the condition. The combination of humidity-induced fatigue and pre-existing ataxia-related fatigue can be particularly draining.

Anecdotal evidence is useful, but it lacks rigorous scientific validity and is open to interpretation. To gain a better understanding of the potential link between humidity and ataxia, let’s look at scientific research.

Scientific Insights: The Humidity-Ataxia Connection

Scientific research on the relationship between humidity and ataxia is limited. Existing studies have produced mixed results. It is important to note that ataxia is a complex neurological condition. Ataxia can be influenced by a wide range of factors, including genetics, overall health, and environmental elements.

Here are some key findings from the existing research:

Temperature sensitivity in multiple sclerosis: A study published in the National Library of Medicine in 2018. It explores the effects of temperature and humidity on multiple sclerosis (MS) patients, a group that sometimes experiences ataxia-like symptoms. The study found that higher temperatures and humidity levels were associated with worsened neurological symptoms, including balance and coordination issues.

Dehydration and Fatigue: Dehydration caused by high humidity levels might make ataxia symptoms worse. Dehydration may lead to muscle weakness and increased fatigue. Making it more challenging for individuals with ataxia to maintain their balance and coordination.

Individual Variability:  Research suggests that the impact of humidity on ataxia may vary from person to person. Some individuals with ataxia may be more sensitive to changes in humidity. While others may not experience significant symptom aggravation.

Lack of Comprehensive Studies: There is a lack of comprehensive, long-term studies specifically focused on the relationship between humidity and ataxia. To establish a clear connection and comprehend how it works, more studies are required.

While the exact mechanisms through which humidity might influence ataxia remain unclear, several theories have been proposed:

Dehydration: High humidity can lead to increased sweating and fluid loss, potentially resulting in dehydration. Dehydration can affect muscle function and coordination. Making it harder for people with ataxia to maintain their balance.

Temperature Regulation: Humidity can affect the body’s ability to regulate temperature. Some ataxia-related symptoms may worsen in response to temperature changes, as the nervous system struggles to adapt.

Central Nervous System Sensitivity:  It’s possible that some people with ataxia have a central nervous system that is more sensitive to environmental factors, including humidity. This increased sensitivity could cause symptoms to worsen.


The question of whether humidity can cause flare-ups in ataxia is a complex one. Although informal data indicates that some ataxia individuals may experience worsening symptoms in humid environments, scientific study on the subject is limited and unclear.

The relationship between humidity and ataxia is likely influenced by various factors. Including individual variability and the specific type of ataxia a person has. For those living with ataxia, it is essential to pay attention to their bodies and how they respond to different environmental conditions. To gain a more comprehensive understanding of the humidity-ataxia connection, further research is needed.
