It’s not just your imagination; your brain really does feel the cold.
Picture this: You step outside into the Minnesota cold, and within minutes your head starts to throb, your fingers go numb, and your thoughts feel sluggish.
It’s not just discomfort, it’s your nervous system reacting to the season.
For many, winter weather doesn’t just chill the skin, it stirs up migraines, nerve pain, and mental fatigue.
Let’s take a look at how cold affects the nervous system and what you can do about it.
Why the Cold Impacts Neurologic Symptoms
Cold weather causes blood vessels to narrow (vasoconstriction), which can reduce circulation to your limbs and brain. That can trigger or intensify symptoms like:
- Headaches and migraines
- Numbness or tingling (especially in neuropathy patients)
- Muscle stiffness or spasticity
- Mood changes or low energy
- Brain fog or reduced focus
Changes in barometric pressure, shorter daylight hours, and indoor inactivity can all compound the issue.
Conditions That May Worsen in Winter
Migraine – Cold is a common trigger. Sudden changes in temperature and pressure can lead to increased headache frequency.
Peripheral Neuropathy – Cold can heighten nerve sensitivity, especially in feet and hands.
Multiple Sclerosis (MS) – While heat is more commonly problematic for MS, cold can lead to muscle tightness, stiffness, and slower mobility.
Raynaud’s Phenomenon – Exaggerated constriction of small blood vessels in response to cold, often seen in fingers or toes.

Tips to Protect Your Nervous System in the Cold
Layer Up Smartly – Keep extremities warm with gloves, thick socks, and layers that insulate without overheating.
Hydrate Daily – Dehydration in winter is common and can trigger fatigue and dizziness.
Stretch & Move – Even light movement indoors improves blood flow and reduces stiffness.
Watch for Triggers – Track migraines or neuropathy symptoms to identify weather-related patterns.
Warm, But Not Too Warm – Extra indoor heat can lead to dehydration and worsen symptoms like headaches or fatigue. Use humidifiers if the air is dry.
Get Outside (Safely) – Aim for at least 10 to 20 minutes of outdoor time daily, weather permitting. Exposure to natural light supports your circadian rhythm, helps regulate melatonin for better sleep, and can reduce feelings of depression or brain fog. Dress appropriately, avoid icy areas, and consider brief walks, even if it’s just around the block or to the mailbox.
Stay Ahead of Flare-Ups – Adjust medications or routines with your neurologist if symptoms worsen seasonally.

When to Call a Neurologist
You don’t need to tough it out through winter symptoms. If cold weather is triggering headaches, numbness, or unexplained changes in how your body feels or functions, it’s time to reach out.
No referral needed.
