Post-Holiday blues: When the tree comes down and your mood follows

It’s January. The last of the Yule log has been eaten, the decorations are back in the basement, and we’re resetting our alarms to 6 a.m. again. In short: Christmas is over… and it feels a bit like hitting a wall.
If you’re feeling drained, nostalgic, irritable or just a bit “meh”, you’re not alone. You’re probably experiencing what’s known as the post-Holiday blues.

So what exactly are the post-Holiday blues?

It’s that little dip in mood that happens after weeks of celebrations, outings and disrupted routines. Experts often compare it to the “post-vacation blues” people get after summer holidays or big trips.

Symptoms can sometimes look like anxiety or a mild depressive episode: fatigue, irritability, trouble sleeping, low motivation… BUT unlike depression, it doesn’t last.

It’s also very common: according to the National Alliance on Mental Illness (NAMI), 64% of people say they feel some symptoms of post-Holiday blues.

Why we feel low after the Holidays

You might think it’s down to higher credit card bills, going back to work or running out of chocolate. But the truth is a bit more layered.

1. The adrenaline crash

December is full-on: emotions, deadlines, family gatherings, travel, cooking, shopping, expectations. Then suddenly… quiet. Your body drops out of high gear, and the crash leaves you feeling empty, tired and moody.

2. The contrast effect

Your brain hates big shifts. Going from “Christmas magic, lie-ins, pyjamas” to “Monday morning, unread emails, boring packed lunches” exaggerates how dull everyday life can feel like.

3. Emotional fatigue

Putting on a brave face, navigating family dynamics, surviving a social marathon can be exhausting. Psychologists say we emotionally “brace” ourselves during the Holidays… so January is when everything loosens and the fatigue hits.

4. Food and drink overload

Alcohol, sugar, a shortage of vegetables, a perfect storm for low mood. A richer Holiday diet often leads to an energy dip once the festivities end.

5. Lack of daylight

January and February are tough months, especially for those affected by Seasonal Affective Disorder (SAD). Less daylight, freezing temperatures… no wonder things feel a bit grey inside as well.

What post-Holiday blues can look like

People experience it differently, but common signs include:

  • A sense of emptiness or sadness
  • Feeling bored after weeks of heightened emotions
  • Losing interest in things you normally enjoy
  • Feeling lonely after all the gatherings
  • Changes in appetite or eating habits
  • Sleeping more than usual or struggling to sleep at all
  • Avoiding social contact
  • Persistent fatigue and low energy
  • Difficulty concentrating or making simple decisions
  • Feeling stressed as everyday life kicks back in
  • Irritability or restlessness
  • Sometimes even a sense of loss, especially if Christmas brought up difficult memories or grief

Once again: this is normal. Your brain is recalibrating.

How to lift yourself out of the post-Holiday slump

A few tips may help you get out of that funk.

1. Ease yourself back in

Give yourself a buffer zone before diving back into full routine. A day or two to reset: light cleaning, sorting out the mail, doing a small grocery, recovering from the emotional jet lag. Don’t jump from “pyjama days” to “peak productivity”.

2. Get back to the basics

Not thrilling, but absolutely essential.

Sleep
Try getting back to your normal sleep schedule (your brain loves structure). Avoid screens before bed; Holiday social media scrolls often lead to pointless, toxic comparison.

Food
Nothing drastic. Just regular, balanced meals, less sugar and alcohol, more real food. Plenty of studies show that a steadier diet = a steadier mood.

Move
Ten minutes of walking is far better than nothing. Daylight paired with movement works almost instantly.

3. Truly reconnect

Social media tends to make January feel worse. Close the apps for a bit. Call someone, meet a friend for a coffee, do a quick FaceTime.

Feeling low? Say so. You’ll be surprised how many people reply with “Me too!”. Talking about it can help you realise you’re not alone.

4. Give yourself something to look forward to

When life feels a bit empty, planning something enjoyable can pick you up quickly.

Simple ideas:

  • A brunch with friends at a new restaurant
  • A relaxed at-home dinner in January where everyone brings a dish
  • Booking an activity: snowmobiling, skiing, dog sledding, ice fishing, whatever’s nearby
  • Starting a hobby, a class or a small project
  • Planning your next getaway, whether it’s a weekend event or a longer trip

5. Put a bit of order back in your mind

January blues often include a lot of overthinking: “I should’ve…”, “Why did…”, “It went wrong when…”.

Take 10 minutes to breathe and step back:

  • Write down what you’re feeling; seeing it in front of you forces a pause and a clearer perspective
  • Separate what you truly feel, from what’s just tiredness or a holiday crash
  • Remind yourself your brain can be misleading: it often romanticises past Holiday seasons and pressures you to recreate unrealistic “magic”

6. Properly decompress

Don’t scroll endlessly! Your nervous system needs stress relief. Try one or two of these:

  • A short guided meditation (even 5 minutes helps)
  • Slow breathing exercises
  • Gentle yoga
  • A funny movie
  • Stepping outside for fresh air
  • A warm bath
  • A gripping book

These are genuine stress interrupters.

7. Be kind to yourself

The golden rule: you don’t need to be at your best in January. You haven’t “failed”. You’re not supposed to love going back to routine. Post-Holiday blues settle on their own in most cases.

But…
If after a few weeks you still feel low, the sadness doesn’t shift, you’re sleeping badly or struggling to function normally, see a professional or even get health advice without having to leave your home. Sometimes what feels like a simple slump may actually be anxiety or the early signs of depression.

A little closing note…

The post-Holiday blues are your brain coming down from a roller coaster. Emotional fatigue, disrupted eating, social pressure, lack of light; they all collide, making January feel gloomier than it is.

Be gentle with yourself. With a few adjustments, a bit of softness and a gradual return to a routine that works for you, your mood will lift and you’ll step into the new year with confidence, energy and a healthier outlook.
