For many with multiple sclerosis (MS), heat is the bigger concern. But a significant minority – around 10-15% – find that cold weather worsens their symptoms. This isn’t just about discomfort; it can trigger increased fatigue, shooting pains, or muscle stiffness, impacting daily life.
Why Cold Affects Some with MS
The exact mechanisms aren’t fully understood. Unlike heat, which can directly disrupt nerve signals (Uhthoff’s phenomenon), cold’s effect is more indirect. However, some individuals with MS experience pain due to nerve damage – such as trigeminal neuralgia – which is triggered by cold.
Trigeminal neuralgia causes severe facial pain, and cold temperatures can provoke episodes in both people with and without MS. It’s still unclear why cold affects some MS patients more than others, but research suggests a link between nerve lesions and temperature sensitivity.
How Cold Impacts MS Symptoms
Cold can worsen existing MS symptoms in several ways:
- Fatigue: Many people with MS report increased tiredness during colder months. This may be linked to reduced activity levels and poorer sleep quality.
- Spasticity: Tightness, stiffness, or involuntary muscle spasms can become more pronounced in cold weather. The “MS hug” – a constricting sensation around the rib cage – may also be triggered.
- Pain: Especially for those with trigeminal neuralgia, cold can induce sharp, shock-like facial pain.
What You Can Do About It
If you find your MS symptoms worsen in the cold, here’s what you can do:
- Dress warmly in layers: This allows for quick adjustments to prevent overheating or excessive chilling.
- Warm up your car: Preheat it before driving, and consider a heated steering wheel for comfort.
- Restorative yoga: Gentle stretching can help warm muscles without overexertion.
- Physical therapy: A single session can provide personalized recommendations for exercise and energy conservation.
- Talk to your doctor: Discuss any worsening symptoms, as there may be underlying conditions requiring treatment.
Simple fixes like light therapy for seasonal affective disorder (SAD) or counseling for mood changes can also make a difference.
The Bigger Picture
Cold weather isn’t the primary trigger for MS symptoms, but it impacts a significant portion of those living with the condition.
Understanding this connection is crucial for managing symptoms effectively. By taking proactive steps and communicating with your healthcare provider, you can minimize the impact of cold weather on your quality of life.
