Can Weather Changes Affect Tremors? Understanding the Impact of Temperature and Climate
It is common for patients with tremors to say that their symptoms seem to fluctuate with the weather. Some say their hands shake even more on cold, chilly mornings, whereas others have even worse tremors on hot, sticky days and during random weather changes. While changes in the weather do not bring on the symptoms of neurological disorders (like essential tremor or Parkinson’s disease), there is a chance they could bring out symptoms.
Do your tremors seem to feel the strongest on the worst days? The study of weather patterns and their effects on neurological disorders is still a growing field of study, but most people agree that there are many factors at play, including the temperature, humidity, stress, and overall physical comfort.
Knowing how the climate can bring out symptoms of tremors may help you manage the symptoms even more.
What are Tremors?
A tremor is a rhythmical but involuntary shaking of a certain body part. While it mostly affects the hands, it can be the arms, head, voice, legs, and/or the jaw.
The two neurologic disorders that have the most tremor association are:
- Essential tremor: usually brings on shaking while in movement or when holding a certain position.
- Parkinson’s disease: usually brings about tremors when the affected body part is at rest and has movement-related symptoms which are also part of the disease.
There is a great variability in the severity of symptoms of tremors, which is individual but also can fluctuate from day to day.
Exploring Weather and Tremors
Many people have observed that their tremors become noticeably worse during certain weather patterns. While there is limited scientific evidence on the connection between the two, doctors accept that environmental factors influence symptom severity.
Weather patterns won’t cause additional damage to the nervous system or speed up the progression of essential tremor or Parkinson’s disease. However, changes to temperature and the environment affect the body’s muscles and circulation. They may also affect stress levels and energy, all of which may impact the severity of tremors.
How Cold Weather Affects Tremors
Cold Weather is one of the most commonly reported triggers of worsening tremors.
When the body is in cold environments:
- Muscles become tense, naturally.
- Blood vessels tighten to conserve heat and reduce blood flow.
- Fine motor control may be more difficult due to stiffness of the hands.
For those who have essential tremor or Parkinson’s disease, the changes listed above may cause shaking to be more pronounced. Cold weather causes additional stress to the body and makes everyday tasks like writing, buttoning, or holding a cup more difficult.
How Hot Weather Affects Tremors
The effects of hot weather are more variable.
For some people, there is little to no impact. For other people, tremors may worsen due to:
- Dehydration
- Fatigue
- Excessive sweating
- Stress
- Poor sleep during hot nights
High temperatures may also affect the way some medications are absorbed or whether they are tolerable, especially when dehydration occurs. The effects may be lessened by drinking plenty of fluids and avoiding overheating.
How Rapid Changes in the Weather Affect Tremors
Rapid changes in temperature or atmospheric conditions may also influence symptoms.
Sudden changes in the environment can cause increased discomfort, anxiety or fatigue, which may lead to temporary worsening of tremors.
It is common to see fluctuations with the changing of the seasons and is particularly noticeable when the transition is from warm to cold or from cold to warm.
What Causes Tremors Besides Changing Weather?
While changes in weather may contribute, it is very rarely the sole cause of why tremors worsen.
Tremors can worsen due to:
- Physical and emotional stress
- Fatigue
- Excess caffeine
- Certain medications
- Low blood sugar
- Illness
The above factors can influence the severity of tremors more than changes in weather.
Keeping a diary of your symptoms can help identify the factor that is causing the change.
What are Symptoms of Tremors?
The underlying symptoms of your neurological condition are not weather dependent; however, some may feel that they are more prominent in certain weather.
Some of the more common symptoms are:
- Shaking or movement of one or both hands
- Difficulty holding or carrying objects without spilling
- Poor hand coordination
- Muscle Stiffness
- Slower movements
- Increased stress or exposure to cold causing increased tremors
- Fatigue that can worsen tremors
If you experience sudden worsening of any of these symptoms or new neurologic symptoms, seek medical attention.
How are Tremors Evaluated?
An extensive evaluation by a Neurologist is necessary to assess the cause of tremors.
Your assessment will likely include:
- a review of your medical history,
- following up on the details of your personal and family history,
- a standard neurological exam, and
- an exam that assesses strength, coordination, and balance.
Doctor’s Observations of Your Tremors
Rest and action of your tremors will be observed, possibly even recorded.
To better see your tremors, the doctor may even have you draw a spiral or place your arms at rest.
Bloodwork and MRIs may be done to rule out other conditions, but will not diagnose essential tremors.
How to Manage Tremors When It’s Cold or Hot
You may dress to stay warm to ease muscle stiffness, hydrate to avoid overheating, and take note of the weather to avoid getting hot. You may also follow a sleep and exercise routine, manage your stress, and ease your tremors by reducing caffeine and increasing your compliance with your medication. You should discuss the effectiveness of each lifestyle and medication change with your neurologist, especially when the changes fail to stop the worsening of your tremors.
When to Consider Seeking More Medical Help
You should consider seeking more medical help if there are rapid changes in the intensity or locations of your tremors, if your daily life is getting harder to function, and if you have developing stiffness in your muscles, an unsteady gait, or slowed movement. You should also seek help when your tremors stop functioning.
Evaluations and Changes to Early Treatment Options
If there are changes to your tremors that are not evaluated frequently, your options for treatment will be limited. The good news is that many tremors can be treated with lifestyle changes and medication.
If tremors impact daily activities, even with medication, MRI-Guided Focused Ultrasound allows specially chosen patients to treat tremors. Since it is a completely non-invasive procedure, carefully selected patients may benefit from it. Only a neurologist can say if you qualify.
Conclusion
It is a myth that Essential tremor and Parkinson’s disease cause symptoms that worsen with weather changes. While this may not be the case, many people still feel that extreme heat, cold, or even changing seasons and weather, along with dehydration and fatigue, may sometimes trigger their tremors.
The best way to feel in control of your tremors year-round is to recognize your triggers, develop a routine, and partner with your doctor. Of course, if your tremors significantly change, the best thing to do is seek help.
FAQs
1. Does essential tremor get worse during cold weather?
Yes. Cold weather can cause muscles to be very rigid. The increased rigidity can cause more noticeable tremors.
2. Does hot weather cause problems for Parkinson’s patients?
Hot weather can cause dehydration and fatigue. These further symptoms of overheating can negatively impact some people. It is always best to stay cool and hydrated.
3. Should symptoms be evaluated when tremors are seasonal?
Dramatic fluctuations in tremors should be evaluated. In the absence of seasonal changes in symptoms, it is best to see a neurologist if there are other symptoms such as muscle stiffness and problems with balance.
