Does Cold Weather Affect Your MS?

When it comes to extreme weather, both heat and cold can affect your MS

Cold weather and multiple sclerosis (MS) would seem to go well together, especially for those who suffer from MS-related heat intolerance. But for many living with MS, symptoms can actually worsen as the temperature drops.

How Temperature Extremes Affect People With MS

Many with multiple sclerosis (MS) are heat intolerant to the point of being unable to function outside at peak summer temperatures. For many, temperatures of 80 degrees or higher are almost unbearable.

However, what is even more interesting about temperature tolerance among people with multiple sclerosis is that many say that while hot temperatures are not comfortable, cold weather and MS don’t go very well together for them, either.

For instance, some people find that cold weather can cause muscle cramping, stiffness, and tightness. It can also worsen the MS hug, which is the gripping feeling around the torso that is caused by spasticity of the tiny muscles between the ribs.

Others find they feel more fatigued in winter months. This could be an indirect result of coping with some of the muscle-related symptoms mentioned above. It could also be that the shorter days and limited sunlight are making their depression worse—as you may know, depression is a common symptom of MS.

Still, others notice that the cold makes walking difficult, which could also be a result of muscle stiffness (worsening spasticity).

Why Does Cold Affect Some People With MS

Experts do not really know why cold temperatures worsen symptoms for some people with MS.

That being said, new data is emerging all the time on the role of vitamin D in MS. Experts have discovered that low vitamin D plays a role in developing MS, but now it’s looking like vitamin D levels also have an impact on relapses and the way we experience symptoms.

It’s been well established that vitamin D levels in people are lower in winter months due to less exposure to sunlight (which is necessary for the body to produce vitamin D). Perhaps we feel our MS symptoms more acutely when our vitamin D reserves are at their winter lows.

Tips for Coping With Cold Weather and MS

Here are some basic tips to help minimize any MS-related discomfort you or a loved one may experience with the cold weather.

Keep Your Hands and Feet Warm

Some people with MS also have a condition called Raynaud's phenomenon, in which the capillaries in the fingers and toes overreact in the cold. As a result, the area under the fingernails and toenails turns blue and can be very painful. Be sure to wear socks even around the house in the wintertime and keep an extra pair of clothes in your car, in case you forget—there is nothing worse than being in a warm car with an ice cold steering wheel.

Soak Up the Sunshine

Go outside during the warmest part of a sunny winter day and soak in a bit of warmth. Even better, get a little exercise outside while you’re at it. And remember, sunlight helps your body produce vitamin D, although, it's hard to make vitamin D when your skin is covered up.

This is why your doctor may increase your vitamin D in the wintertime (be sure to not do this on your own, however).

Don't Overdo the Heat Inside

As a result of the cold, you may run really hot baths or showers. But be careful. Remember, extreme heat is not your friend, either. In the end, it's a delicate balance, so air on the side of moderation rather than extreme.

Warm Yourself From the Inside

Try drinking warm beverages like a cup of hot chocolate, tea, or decaf coffee to take the chill off and warm your body’s core faster.

A Word From Verywell

Cold weather and MS may not go together as you might like, but you can learn to tolerate the combination better.

Like many other MS-related situations that you must get through, a little strategic planning about winter activities can help you have at least a little control over symptoms.

Put some thought into what you enjoy doing in the winter, take proper precautions, and get the most out of the cold months.
