What Are the Best Cooling Vests for Multiple Sclerosis (MS)?

Medically reviewed by Steven Kim, MD on December 21, 2015Written by Juliann Schaeffer on December 21, 2015

If you have multiple sclerosis (MS), it’s likely that the sun and the heat are your foes. Warm temperatures can have a significant effect on MS symptoms, says Hal Gutstein, MD, a clinical assistant professor of neurology at NYU Langone Medical Center Multiple Sclerosis Comprehensive Care Center.

Even a slight increase in temperature, something as little as 0.5 degrees Fahrenheit, can worsen and agitate symptoms. The following can also worsen your MS symptoms:

  • exercise or an overly active lifestyle
  • hot showers or baths
  • fever from a cold or other acute illness

In medical terms, this is known as Uhthoff's phenomenon. As Gutstein explains, overheating was actually the basis for diagnosing MS prior to the use of magnetic resonance imaging (MRI). Since a slight temperature increase can impair nerve impulses enough to cause symptoms, a “hot tub test” was once used to spur on symptoms.

While temporary, such small temperature increases can greatly impact your quality of life. Fortunately, cooling vests can help to maintain your core body temperature, prevent temperature fluctuations, and reduce flare-ups.

There are different kinds of cooling vests with varying price points and features. Battery or electrical-powered vests, called active cooling vests, can be more expensive but can cool the body longer. Gel pack or passive cooling vests don’t provide such long-lasting cooling, but they are usually cheaper.

Before you purchase a cooling vest, take a look at these top seven models.

1. First Line Basic Cooling Vest

Choosing a Vest

Regardless of what type of vest you choose, Gutstein recommends making sure it fits you properly around the torso. A vest that is too loose-fitting may not give you the desired effect.

Cooling vests are not usually covered by health insurance. Still, it never hurts to double check with your insurance provider. Some programs may also help offset the cost, such as Multiple Sclerosis Association of America and the Multiple Sclerosis Foundation. Military veterans may also qualify for a free Polar cooling vest through the United States Department of Veterans Affairs.

No matter what cooling vest you choose, or if you opt to try other cooling techniques instead, the most important thing is to listen to your body and to know your limitations. MS and its symptoms can be successfully managed.
