Cooling Vests for Multiple Sclerosis — Arctic Heat USA
Why Heat Affects People with MS
People with Multiple Sclerosis often experience a temporary worsening of symptoms when their body temperature rises — a phenomenon known as Uhthoff's syndrome. Even a small increase in core temperature of just 0.5°C can trigger or worsen symptoms including fatigue, blurred vision, weakness, numbness and cognitive difficulties.

This is not permanent damage — symptoms typically resolve once the body cools — but it can severely limit daily activity and quality of life during warm weather.
Cooling Vests for Multiple Sclerosis
Pre-cooling and active cooling with a lightweight body cooling vest helps MS patients manage their body temperature during physical activity, outdoor exposure and warm weather. By keeping skin temperature lower, the vest helps prevent the temperature rise that triggers Uhthoff's symptoms. Many MS patients report being able to exercise longer, walk further, and participate in everyday activities they would otherwise need to avoid in summer.
What Temperature Triggers MS Symptoms?
For most people with MS, a core body temperature rise of just 0.5°C (0.9°F) is enough to trigger noticeable symptom changes. This is why even mild summer heat, a warm bath, or light exercise can cause problems. The goal of cooling therapy is not to make you cold — it is to prevent that half-degree rise from happening in the first place.

Can I Wear It While Exercising?

It is also effective for recovery — worn after exertion while the body temperature returns to normal.
How Long Does It Stay Cool?
Typically up to 2 hours in moderate conditions. In hot weather or during intense activity, cooling duration will be shorter. For longer outings, some patients purchase two vests — wearing one while the other refreezes.

Frequently Asked Questions — Cooling Vests for Multiple Sclerosis
Is a cooling vest suitable for all MS patients?
Most MS patients with heat sensitivity benefit from cooling vests. However if you have any concerns about suitability for your specific condition, consult your neurologist or MS nurse before use.
Can I wear it over my regular clothing?
Yes, though wearing it against the skin or under a thin layer gives the best cooling contact. When used in frozen mode it will not make outer clothing wet.
How do I clean it?
Hand wash in warm soapy water for 1–2 minutes and hang to dry. Alternatively use a gentle machine wash cycle on a front-loading machine.
Does Medicare or insurance cover cooling vests?
In some cases yes — speak to your neurologist who may be able to provide supporting documentation. The National MS Society can also provide guidance on cooling assistance programmes.
