Holiday Blues or Depression? Why January Feels Flat Too

Feeling low around the holidays is common, and for plenty of people it lingers, or even shows up, after the decorations come down. “Holiday blues” and “January blues” are familiar phrases, but neither one is a diagnosis. They describe a real experience, not a medical condition. So when people search for “holiday depression,” the question underneath is usually simpler: is this a passing slump, a seasonal pattern, or depression that needs attention?

This post covers how to tell those apart, what the research does and doesn’t show, and why the flat stretch after New Year’s can catch people off guard. For what winter itself does to light, activity and sleep, see Winter and Your Mood.

What the Holiday Blues Usually Look Like

NIMH describes the holiday blues as feelings of sadness or anxiety brought on by stresses at certain times of the year. You might feel tired, sad, irritable or lonely, and you can usually point to what’s feeding it.

• Money. In a 2025 American Psychiatric Association poll, 46% of U.S. adults said they worried about affording or finding holiday gifts.
• Family. Time with relatives who are hard to be around, or no family to be with at all.
• Someone missing. The first or the tenth holiday without a person you love.
• Broken routines. Later nights, travel, more alcohol and less sleep.
• The gap. The distance between how the season is supposed to feel and how it does.

Low feelings like these tend to come and go with what’s happening around you. You may have a hard morning and still enjoy dinner with a friend that night. Everyday sadness usually passes, NIMH notes, and that’s one of the things that sets it apart from depression. Here’s more on the difference between depression and sadness.

What the Research Does and Doesn’t Show

Holidays and mood have been studied less than you might expect, and much of what exists is old, small or drawn from hospital records rather than everyday life. With that caveat, here’s roughly where things stand.

• Everyday mood may dip. A 2011 review concluded that general mood may worsen around Christmas, though very few studies looked at it directly.
• Psychiatric emergencies don’t seem to climb. A 2023 systematic review of 25 studies found Christmas holidays weren’t linked with more use of emergency psychiatric services, and hospital admissions were lower on Christmas and other holidays than the rest of the year. Fewer admissions may partly reflect admissions being put off: the same review found January had the highest numbers, so it doesn’t necessarily mean less distress.
• Afterward may be different. Several studies have found more crisis visits or suicide attempts in the weeks after Christmas, including an older U.S. study at an emergency service that found fewer visits before Christmas and a rise afterward, an international study of suicide attempts in 13 European centers, and the 2023 review’s finding about January. The 2011 review describes a similar rebound. Not every study agrees, one UK study found no rise after Christmas, and the reasons aren’t clear.

Much of this work focuses on Christmas, so it says little about other traditions or about January in particular.

One belief deserves a direct answer: that suicide peaks over the holidays. The data don’t support it. In CDC provisional data for 2024, reported by the Annenberg Public Policy Center, December had the lowest average daily rate of any month. In U.S. data from 2015 to 2020, suicides in most age groups tended to peak in late spring and early summer, not over the holidays. The one holiday that stands out is New Year’s Day: a 2025 meta-analysis found higher risk that day across most countries, for reasons that haven’t been established. The same review found lower risk on Christmas Day, but that finding is weaker: a large 26-country study, an international study, found only weak evidence for it. That’s a reason to take a hard stretch seriously whatever the calendar says, not a reason for alarm. If you’re in crisis or thinking about harming yourself, call or text 988 (Suicide & Crisis Lifeline), any time, day or night. In an emergency, call 911 or go to the nearest emergency room.

How Depression Is Different

NIMH describes depression as depressed mood or loss of interest, most of the day, nearly every day, for at least two weeks, along with other symptoms such as fatigue, trouble concentrating or changes in sleep, and it gets in the way of daily activities. That’s a reason to get checked, not a checklist to diagnose yourself. Other common signs include:

• Hopelessness, guilt or feeling worthless
• Fatigue or feeling slowed down
• Trouble concentrating or making decisions
• Trouble sleeping or oversleeping, or changes in appetite
• Irritability or restlessness
• Thoughts of death or suicide

The useful question isn’t how sad you feel. It’s how long this has lasted and how much it’s taking from you. You don’t have to feel sad at all: losing interest in the things you normally care about counts too. And depression doesn’t keep to a calendar, so it may not lift when the holidays end. Our depression guide covers how it’s evaluated and treated.

Seasonal depression is a type of depression that comes back at the same time each year. It’s linked to shorter daylight hours, usually starts in late fall or early winter, and lasts about 4 to 5 months of the year. Shorter days are one of several proposed causes, along with changes in the body clock, melatonin and serotonin, and it sometimes runs in families. Less often, it happens in summer, and it can look different: trouble sleeping and a poor appetite instead of oversleeping and overeating. Vitamin D comes up often here too; our post on vitamin D, B12 and iron covers what the research does and doesn’t show. NIMH is clear that it shouldn’t be confused with the holiday blues. Light therapy, a type of talk therapy called CBT, and antidepressants are all well-supported options for seasonal depression, and bupropion XL (Wellbutrin XL) is FDA-approved to help prevent winter depression from coming back, when appropriate. If you’ve ever had periods of unusually high energy or little need for sleep, talk to a provider before using a light box, since bright light can trigger those episodes. We don’t offer standalone weekly therapy, but we’re happy to help you find a therapist and, with your permission, we’ll coordinate with them.

Why January Can Feel Flat Too

There’s very little direct research on the January blues. These are common explanations rather than measured causes, but many people will recognize at least one.

• The letdown. Weeks of planning and anticipation stop, and the calendar empties all at once.
• Back to full speed. Work and routines restart with no gentle ramp, often while you’re still tired.
• The bills. Holiday spending shows up as a statement, after the fun of it is over.
• Still dark. The holidays end, but the short days don’t.
• Resolutions. A deadline to become a new person on January 1 can turn ordinary tiredness into a feeling of failing.

Timing plays a part too. Plenty of people hold together through the holidays and feel it once the pressure lifts, so feeling worse in January doesn’t mean something new has gone wrong.

You may also hear about “Blue Monday,” the third Monday in January, billed as the most depressing day of the year. That’s a marketing idea, not a finding. It reportedly began in 2005 as a promotion for a travel company, Sky Travel, and researchers who looked at it concluded its formula has no strong scientific foundation. No single date is the most depressing day of the year.

No good study says exactly how long post-holiday blues last. Many people find they ease as routines settle. If low mood has been there most of the day, nearly every day, for two weeks or more, or it’s still going into late January, it’s worth a closer look.

When It’s Worth Getting Evaluated

• Low mood or loss of interest, most of the day, nearly every day, for two weeks or more
• A past depression that seems to be coming back
• Drinking more to get through the day
• Pulling away from people you’d normally see
• Falling behind at work or at home
• Thoughts of death

That last one doesn’t need to wait for the others. If you’re in crisis or thinking about harming yourself, call or text 988 (Suicide & Crisis Lifeline), any time, day or night. In an emergency, call 911 or go to the nearest emergency room.

You don’t need to work out which of these patterns you have before asking for help. Sorting that out is what an evaluation is for: when this started, what else is going on, and whether past winters looked the same.

What Helps in the Meantime

None of this is a cure, and none of it replaces treatment if this is depression. These are small steps for a rough patch, several of them from NIMH’s own suggestions.

• Keep sleep and meals regular. Try to hold a steady bedtime and wake-up time, even after a late night.
• Get some morning daylight when you can. Winter and Your Mood has more on light.
• Put one thing on the January calendar. A dinner, a class, a walk with a friend. Having something to look forward to can make the weeks after the holidays feel less empty.
• Avoid alcohol. NIMH advises people with depression to avoid it.
• Tell one person how you’re really doing. One honest text is enough to start.
• Shrink the resolutions. Pick one or none. Decide what has to get done and what can wait.

Frequently Asked Questions

Why do I feel depressed after the holidays?

Often it’s a mix: the letdown after weeks of anticipation, the return to work, bills, short days, and tiredness that catches up once the pressure lifts. For many people that eases as routines return. If low mood or loss of interest has lasted most of the day, nearly every day, for two weeks or more, or it’s getting in the way of daily life, it could be depression and is worth having checked.

How long do post-holiday blues last?

There’s no research-based answer. Many people find they ease as routines return. Two weeks of low mood or lost interest, most of the day, nearly every day, is a reasonable point to talk with a provider rather than waiting it out.

Is holiday depression real?

“Holiday depression” isn’t a diagnosis, and neither is “holiday blues.” But depression that happens to start or worsen during the holidays is real, and it deserves the same care as depression at any other time of year.

How do I know if it’s seasonal depression?

Look across years rather than at this one winter. Seasonal depression comes back around the same time each year, usually late fall or early winter, and lasts for months. In winter it often brings oversleeping, overeating and pulling away from people, and it’s linked to shorter daylight hours rather than holiday dates.
