Why January Is the Hardest Month for Your Nervous System (And How to Survive It)
It's January 3rd. The decorations are down. The guests are gone. Your calendar is finally empty.
So why do you feel MORE exhausted than you did during the chaos of the holidays?
You thought you'd feel relieved. Instead, you feel completely wiped out. Like you can barely get out of bed. Like your body just... gave up.
Here's what nobody tells you: January is the hardest month for your nervous system.
And it's not because you're weak. It's not because you need to "just push through."
It's because your body has been running on stress hormones for weeks, and now it's crashing.
Let me explain what's actually happening in your body right now.
Your Body Just Ran a Marathon (Even If You Didn't Move)
Think about the last 6-8 weeks.
You were:
Shopping, cooking, cleaning, decorating
Managing family dynamics and trying to keep the peace
Saying yes to every party, event, and gathering
Trying to make everything "perfect" for everyone else
Staying up late, eating on the go, skipping your normal routines
Dealing with family stress, money stress, and the pressure to be cheerful
Your nervous system saw all of that as DANGER.
Every time you felt stressed, anxious, or overwhelmed, your body released stress hormones, mainly cortisol and adrenaline.
These hormones gave you the energy to keep going. To push through. To get it all done.
But here's the problem:
Your body wasn't designed to run on stress hormones for weeks at a time.
It was designed to use them for SHORT bursts, like running from a bear. Not for running from Thanksgiving to New Year's.
And now? Your body is out of gas.
The Post-Holiday Cortisol Crash
Here's what happens when you finally stop:
For weeks, your body was making TONS of cortisol to keep you going.
Then the holidays end. The stress stops (kind of). And your body says, "Okay, we can finally rest now."
But your cortisol doesn't just go back to normal.
It crashes.
And when cortisol crashes, you feel:
Exhausted (even after sleeping 10+ hours)
Brain fog (can't think clearly, can't remember things)
Zero motivation (everything feels too hard)
More anxious or sad than usual
Body aches and pains
Getting sick (because your immune system is shot)
This is called post-holiday burnout. And it's REAL.
Your nervous system is stuck in what we call "freeze mode."
You're not in fight-or-flight anymore. You're just... frozen. Exhausted. Shut down.
But Wait, There's More (Sorry)
The cortisol crash is just ONE reason January is so hard.
Here are the other things making it worse:
1. You're Not Getting Enough Light
In December and January, the days are SHORT. It gets dark at like 5pm.
And your body NEEDS light to make important brain chemicals like serotonin (the happy chemical).
Less light = less serotonin = you feel more depressed and tired.
Light also controls your cortisol. Your body is SUPPOSED to make cortisol in the morning when the sun comes up. That's what helps you wake up and have energy.
But when it's dark all morning? Your body gets confused. Your cortisol pattern gets messed up.
So you can't wake up in the morning. And you can't sleep at night.
2. Your Vitamin D Is Probably Low
Vitamin D comes from sunlight. And in the winter, there's not much sun.
Low vitamin D makes you feel:
Tired
Sad or anxious
Achy
Weak
Foggy
And it messes with your immune system. That's why everyone gets sick in January.
3. Your Body Is Working Harder Just to Stay Warm
When it's cold outside, your body uses MORE energy just to keep you at the right temperature.
That's energy you don't have right now.
So you feel even MORE exhausted.
4. The "New Year, New You" Pressure Is Stressing You Out
Everyone is talking about resolutions. Getting healthy. Losing weight. Being more productive.
And if you're already exhausted and burned out, that pressure feels AWFUL.
You feel like you SHOULD be doing more. But you can barely do the basics.
And that creates MORE stress. Which makes your nervous system worse.
5. You're Probably Broke (Or Stressed About Money)
The holidays are expensive. And now the credit card bills are coming.
Financial stress is one of the BIGGEST stressors for your nervous system.
6. You're Alone Again
During the holidays, you were busy with people (maybe too busy).
But now? Everyone goes back to their normal lives. And you might feel lonely or disconnected.
For your nervous system, social connection = safety.
When you feel alone, your nervous system feels UNSAFE. And that keeps you stuck in stress mode.
Is It Seasonal Depression or Something Bigger?
A lot of people call this "seasonal depression" or "the winter blues."
And yes, Seasonal Affective Disorder (SAD) is real.
But here's what I want you to know:
If you feel like this EVERY January... or if you've been feeling like this for MONTHS (not just January)...
It might not be seasonal. It might be chronic nervous system dysregulation.
Here's the difference:
Seasonal Affective Disorder (SAD):
You feel okay in spring, summer, fall
You only struggle in winter (November-February)
Light therapy helps
It gets better when the days get longer
Chronic Nervous System Dysregulation:
You feel exhausted and burned out YEAR-ROUND
Winters are just WORSE
Light therapy helps a little, but not enough
You never fully recover
If this sounds like you, January isn't the problem.
January is just HIGHLIGHTING the problem.
Your nervous system has been stuck in survival mode for a long time. And you need more than just "wait for spring."
What to Do If You're Struggling Right Now
Okay, so now you know WHY January is so hard.
But what do you actually DO about it?
Here's what helps:
1. Get Light in the Morning
As soon as you wake up, get outside. Even for 10 minutes.
If it's too cold or dark, get a light therapy lamp (also called a SAD lamp). Sit in front of it for 20-30 minutes while you drink your coffee.
This helps reset your cortisol and tells your body it's daytime.
2. Take Vitamin D
Most people need 2,000-5,000 IU of vitamin D per day in the winter.
(Take Vitamin D3 with vitamin K2 so your body uses it properly.)
If you've never tested your vitamin D, get it tested. You want your levels between 50-80 ng/mL. Most doctors say 30 is "fine," but that's not optimal.
3. Don't Start a Harsh Diet or Detox
I know everyone is talking about "New Year, New You" and detoxes.
But if your body is already exhausted and your nervous system is crashed...
A restrictive diet or detox will make it WORSE.
Your body doesn't have the energy to detox right now. It needs FUEL. It needs support.
Eat regular meals. Don't skip breakfast. Get enough protein and healthy fats.
Your body needs to feel SAFE before it can heal.
4. Move Gently (Don't Push)
You might think, "I need to exercise more! I need to get back in shape!"
But if you're exhausted, intense exercise will DRAIN you more.
Instead:
Go for walks outside (sunlight + gentle movement)
Do gentle stretching or yoga
Dance in your living room
Anything that feels GOOD, not punishing
Your nervous system needs to feel safe. Punishing workouts send the message that you're in danger.
5. Regulate Your Nervous System
This is the most important one.
Your nervous system is stuck. You have to actively help it SHIFT out of freeze mode.
Here are some simple ways:
Vagal toning exercises:
Hum or sing (it activates the vagus nerve)
Gargle with water (sounds weird, but it works)
Take deep breaths where the EXHALE is longer than the inhale (breathe in for 4, out for 6)
Grounding:
Put your bare feet on the ground (yes, even if it's cold, just for a minute)
Notice 5 things you can see, 4 things you can hear, 3 things you can touch
Warmth:
Take warm baths
Use a heating pad
Drink warm tea
Warmth signals SAFETY to your nervous system
6. Give Yourself Permission to Rest
This is hard for a lot of women. Especially if you're used to being the one who does everything for everyone.
But you HAVE to rest.
Not just sleep. But actual REST.
That means:
Saying no to things
Canceling plans if you need to
Asking for help
Letting some things go
Your body is telling you it needs a break. LISTEN.
7. Connect with Safe People
Your nervous system needs connection to feel safe.
Reach out to friends. Join a support group. Talk to people who GET IT.
Isolation makes everything worse.
You're Not Alone in This
If you're struggling with burnout, exhaustion, and feeling like your body is giving up on you, I have a free Facebook community full of women just like you.
We talk about nervous system healing, root causes of fatigue, and how to actually recover (not just push through).
When to Get Help
If you've been struggling for MONTHS (not just this January)...
If rest doesn't help...
If you feel like something deeper is wrong...
It's time to test your nervous system and hormones.
Here's what I recommend testing:
DUTCH Hormone Test:
Shows your cortisol pattern throughout the day
Tells you if your cortisol is HIGH, LOW, or backwards
Shows if your stress hormones are affecting your other hormones
Vitamin D, B12, and Iron:
These are the big three for energy
Most doctors only check if they're "in range," but you want them OPTIMAL
Full Thyroid Panel:
Not just TSH
You need Free T3, Free T4, Reverse T3, and antibodies
Low thyroid makes EVERYTHING worse in the winter
I help women test these things and find out what's ACTUALLY going on.
Because "just get more sleep" and "wait for spring" isn't enough if your body is stuck.
You're Not Broken. You're Just Stuck.
If you're reading this and nodding along to every word...
If you feel SEEN for the first time in months...
I want you to know:
You're not broken.
You're not lazy.
You're not "just depressed."
Your nervous system has been in survival mode for too long. And now it's stuck in freeze.
January is hard because:
Your cortisol crashed after weeks of stress
You're not getting enough light
Your vitamin D is low
Your body is cold and tired
Everyone expects you to be "better" now
But you don't FEEL better. You feel worse.
And that's OKAY.
Your body isn't failing you. It's PROTECTING you.
It's forcing you to slow down because you wouldn't slow down on your own.
So be gentle with yourself.
Rest without guilt.
Get the light and the warmth and the support your body needs.
And if you need help figuring out if this is seasonal or something deeper, I'm here.
January is the hardest month for your nervous system.
But it doesn't have to break you.
With the right support, light, warmth, rest, nervous system practices, and maybe some testing, you CAN recover.
You don't have to just "survive" until spring.
You can actually HEAL.
And I'm here to help you do that.
Take care of yourself, okay?
You deserve to feel better.
