You’re not imagining it: The drop in temps can trigger migraines.
If you feel like your migraines always seem to happen when the winter months come around, it might not be your imagination. “Cold weather can most definitely increase the risk of migraines in individuals,” says Cynthia Armand, MD, neurologist at Montefiore Medical Center in New York City.
There are a number of reasons winter can trigger more migraines:
Lower barometric or atmospheric pressure, which disrupts the equilibrium between the pressure in the air and the pressure in your sinuses
Snowstorms, which brings sudden dips in atmospheric pressure
Dry air, which can lead to dehydration (a common migraine trigger)
Indoor heating, which further dries the air and triggers dehydration and migraines
Extreme temperature changes between indoors and outdoors
And cold drafts that come in from windows and doors.
How to Protect Yourself from Winter Migraines
“In the cold winter months, it’s really important to be consistent and protect yourself in order to prevent migraines from occurring,” says Dr. Armand. A big part of preventing winter migraines is by moderating the extremes.
“When you’re going outside in the cold weather, you want to make sure that you bundle up. Wear a scarf. Insulate your head with a hat. That will shield you from the cold temperature drops that happens from moving from inside to outside,” says Dr. Armand.
Insulating yourself from the cold can help prevent migraines when you’re outdoors, but you also want to moderate the indoor extremes: the hot, dry air.
“When the heat is on, it shouldn’t be too high. It should be at a moderate level that doesn’t induce too much sweating on the body that can cause dehydration,” says Dr. Armand. Additionally, identify and insulate against drafts coming from windows and doors, which can help reduce temperature shifts within the house or office.
Preventing Winter Migraines from Dehydration
Many winter migraines are actually triggered from dehydration. You often think of the cold air and indoor heat as drying out your skin, but the dehydration goes beyond the epidermis.
“We know that dehydration is a very potent trigger of migraine, and we lose water on a day-to-day basis. We go to the bathroom, we sweat, so we want to make sure that we replenish that water in the body,” says Dr. Armand. Keep a water bottle on hand to help encourage you to keep drinking throughout the day.
Another option is to get a humidifier for your home or workspace. Says Dr. Armand, “Humidifiers produce moisture in the air. The air can be very dry from the heat indoors, so that’s actually a nice way to control the temperature and help keep the body hydrated.”
Finally, one of the best ways to prevent seasonal migraines is simply by sticking to your migraine prevention habits: Eat regularly, avoid triggers, keep a headache diary, stick to a sleep schedule, and stay hydrated. “The migraine brain loves a schedule,” says Dr. Armand.
If you’re still getting migraines despite lifestyle changes, be sure to see a doctor, ideally a headache specialist, to help identify the problem and fine-tune the management of your migraines.

00:00.800 --> 00:03.466
00:03.467 --> 00:05.466
Cold weather can most definitely increase the risk
00:05.467 --> 00:07.332
of migraines in individuals.
00:07.333 --> 00:10.299
So with the cold, there's a drop in temperature,
00:10.300 --> 00:13.366
and that change itself can cause a migraine.
00:13.367 --> 00:17.099
There's also the risk of further drop in barometric pressure
00:17.100 --> 00:19.899
with snowstorms that might come about and winds,
00:19.900 --> 00:22.999
so that itself can cause migraine as well.
00:23.000 --> 00:30.666
00:30.667 --> 00:34.966
It's really important to be consistent and protect yourself
00:34.967 --> 00:37.199
in order to prevent migraines from occurring.
00:37.200 --> 00:40.332
So when you're going outside in the cold weather,
00:40.333 --> 00:42.099
you want to make sure that you bundle up.
00:42.100 --> 00:45.666
Wear a scarf, insulate your head with a hat.
00:45.667 --> 00:49.066
That will shield you from the cold temperature drops
00:49.067 --> 00:52.332
that happens from moving from inside to outside.
00:52.333 --> 00:54.232
That will shield you from the wind,
00:54.233 --> 00:58.799
and that can essentially help with migraine control.
00:58.800 --> 01:01.132
It is very important for individuals with migraine
01:01.133 --> 01:03.632
to keep the body very hydrated.
01:03.633 --> 01:06.866
We know that dehydration is a very potent trigger of migraine.
01:06.867 --> 01:11.132
We know that the cold air can be very, very, very drying.
01:11.133 --> 01:13.266
People can become very parched,
01:13.267 --> 01:15.966
and that's a representation of the body's hydration state.
01:15.967 --> 01:18.866
When we crank up the heat in the winter time,
01:18.867 --> 01:23.566
it can cause the air and surfaces to become very dry,
01:23.567 --> 01:26.666
and that can cause our bodies to be very dry,
01:26.667 --> 01:28.966
and that dryness can lead to dehydration,
01:28.967 --> 01:32.132
so we want to make sure that we replenish that water in the body,
01:32.133 --> 01:35.799
so we need to at least drink seven to eight glasses a day,
01:35.800 --> 01:39.766
and if that's hard, try to make sure you drink water
01:39.767 --> 01:43.066
when you get up from sleeping, before each meal.
01:43.067 --> 01:45.932
That will kind of keep it in there and keep the body hydrated.
01:45.933 --> 01:48.899
When we are indoors and the heat is on,
01:48.900 --> 01:51.132
in order to prevent a migraine, we want to make sure
01:51.133 --> 01:55.499
that there isn't a change in the temperature that's so extreme,
01:55.500 --> 01:58.832
so when the heat is on, it shouldn't be too high.
01:58.833 --> 02:02.066
Sometimes there might be little drafts that come in
02:02.067 --> 02:04.166
through the windows and through the doors.
02:04.167 --> 02:07.699
Insulating those drafts and covering them up is important, too,
02:07.700 --> 02:11.132
because those can cause temperature shifts in the home,
02:11.133 --> 02:14.766
and that can also lead to migraine attacks.
02:14.767 --> 02:18.266
Humidifiers produce moisture in the air.
02:18.267 --> 02:20.966
The air can be very dry from the heat indoors,
02:20.967 --> 02:24.732
so that's actually a nice way to control the temperature
02:24.733 --> 02:27.232
and help keep the body hydrated.
02:27.233 --> 02:30.266
A lot of the times, with seasonal changes,
02:30.267 --> 02:33.699
individuals can feel very disheartened and sad
02:33.700 --> 02:37.866
because they feel as though they can't control what is occurring.
02:37.867 --> 02:41.766
I want to make sure that they know they're doing the right thing,
02:41.767 --> 02:45.366
and to continue on being consistent.
02:45.367 --> 02:47.699
The migraine brain loves a schedule,
02:47.700 --> 02:51.099
and they want to make sure that they're eating regularly,
02:51.100 --> 02:53.832
sleeping regularly, and staying hydrated.
02:53.833 --> 02:56.766
That's the first level of armor.
02:56.767 --> 02:59.799
Once they have that armor, they can do anything,
02:59.800 --> 03:02.899
and that's how they take back that control.
03:02.900 --> 03:07.467
