Why mornings are the worst: diurnal mood variation in depression

“At seven in the morning I’d sign a statement that my life is a disaster. At seven in the evening I think it might just work out.”

I hear this sentence, in different versions, more often than you might think. You wake up and before you even open your eyes it is there: a weight on your chest, a grey filter over everything, the thought that today is not going to work. Getting up is like climbing out of a hole. Then the day somehow unfolds. The afternoon is a little easier. In the evening you might even laugh at a series and wonder whether you imagined the morning. And the next day it all starts again.

Clinically, this pattern is called diurnal mood variation. For many people with depression, the morning is the hardest part of the day. In this post I will explain why that is, what cortisol and the internal clock have to do with it, and above all how you can make mornings at least a little easier. I will not give medical advice — talk to your doctor or psychiatrist about medication, doses and when to take them. But I can help you understand what is going on and suggest a few steps that anyone can manage.

What morning depression is

“Morning depression” is not a separate diagnosis. It is an everyday name for a pattern in which the symptoms of depression are stronger in the morning and ease during the day. The DSM-5 psychiatric manual counts mood that is regularly worst in the morning — together with early morning waking, marked slowing or agitation and loss of the capacity for pleasure — among the signs of the so-called melancholic form of depression.

But that does not mean everyone who feels worse in the morning has melancholic depression. Diurnal variation is fairly common in other forms of depression too, and in some people it appears only now and then. Anna Wirz-Justice, one of the leading researchers of circadian rhythms, pointed out in a 2008 review that the picture is far more varied than the textbooks suggest: for some people it is worst in the morning, for others in the evening, and for others still the pattern changes from day to day.

What they all share: mood in depression is not a flat line. It has its own daily pulse. And that pulse is linked to the body’s internal clock.

Cortisol: the hormone that gets you on your feet in the morning

When you wake up, something happens in your body that you do not notice. Cortisol, a hormone often called the stress hormone although its role is much broader, rises steeply in the first thirty to forty-five minutes after waking. This is called the cortisol awakening response. According to a review published in 2009 by Fries, Dettenborn and Kirschbaum, in most healthy people cortisol levels rise during this time by about half on average compared with the level at waking.

This rise is not a mistake. It is part of getting ready for the day: it raises blood sugar, sharpens attention and puts the body into a state of readiness. In a healthy person we mostly do not feel it — or we feel it as the energy with which we get up.

In depression, however, the stress response system is often tuned differently. In some people cortisol levels are raised overall; in others the morning response is stronger or flattened. Research is not entirely consistent, and no direct line of “more cortisol = worse morning” can be drawn. What we can say is this: in the hours when the body is getting ready for the day, for some people with depression that preparation is more like an alarm than an awakening. And we experience an alarm without a clear reason as anxiety, heaviness, a sense that the day will be bad.

An internal clock that is out of step

The second part of the explanation is the circadian rhythm — the internal clock that governs sleep, wakefulness, body temperature and hormone release. In depression this clock is often slightly shifted or flattened. The body may “think” it is still night while the alarm is already dragging you out of bed. Or the different rhythms that should run together — temperature, melatonin, cortisol, sleep — drift apart from one another.

One explanation of diurnal variation is that a person with depression wakes in the morning at a phase when their internal clock is not yet ready for the day. Over the day, with light, movement and contact with others, the clock slowly falls into step and mood improves. In the evening, when the system is most “aligned”, mood is at its best too. This explanation is not final, but it does account well for why morning light and a fixed rising time help a little for many people.

The third part is sleep itself. In depression it is often shallow and broken, with early waking. Someone who wakes at four and then lies with their thoughts for two hours has already fought the first battle of the day by seven. I have written more about this in Depression and sleep: why you sleep too much or too little, and about waking at three in Waking at three: what cortisol and a racing mind are telling you.

What happens in your head in the first few minutes

People often describe morning depression in similar ways. It is not necessarily sadness straight away. It is more like emptiness, heaviness, slowness — as if you had to wade through thick honey. And then the thoughts arrive.

In the morning the mind likes to review everything that lies ahead. Not as a to-do list, but as a verdict: I won’t manage this, I’ll mess that up, there’s no point. Because energy is low, every task looks bigger than it is. And because mood is at rock bottom, it feels as if it will be like this all day, all week, forever. We call this circle of thoughts rumination, and in the morning, while you are still lying in bed, it has the easiest job of all.

It is important to understand one thing: the morning forecast is not reliable. When at seven you are certain the day will be unbearable, it is your mood speaking, not the facts. That does not mean the feeling is false — it is real and heavy. It only means it is not prophetic. I have tried to describe what depression feels like from the inside in What depression feels like from the inside.

What this sounds like in conversation

In sessions, mornings often come to light only when I ask about the whole day, not just “how are you”. Such a conversation might sound like this (composed, not a real person):

“When in the day is it hardest for you?”
“In the morning. The first five minutes are the worst. I open my eyes and I know it’s going to be one of those days again.”
“And then?”
“Then I somehow get myself up. Until lunch I’m like a zombie. The afternoon’s better, and by the evening I’m almost normal.”
“When you’re almost normal in the evening, how do you see the morning?”
“Then I think I’m exaggerating. That I’m just lazy. And then in the morning it all happens again.”

Hidden in this short exchange is a trap many people know. Because the evening is better, we explain the morning state as weakness, laziness or lack of willpower. But it is a predictable pattern with its own background. I wrote about exactly why depression takes away your drive in Why depression takes your drive exactly when you need it most.

Why the morning is not your fault

People with morning depression are often ashamed. Because they are late, because they cancel morning appointments, because they take the children to school late or not at all. Those around them often do not help: “If you went to bed earlier, you’d find it easier to get up.” “Just get started and it’ll be fine.”

This advice misses the point. The morning state in depression is not a matter of discipline. It is made up of biological rhythms, exhausted sleep and thoughts coloured by depression. That does not mean you have no power at all — quite the opposite, there are things you can do. But you have to start with understanding, not with blame. Shame only adds one more layer of weight that you have to lift in the morning.

If you work and everything functions on the outside, while inside you climb out of a hole every morning, you may recognise yourself in High-functioning depression: when everything works outside and it is empty inside.

Exercise: a morning in five small steps

This exercise does not promise a good morning. It only promises a morning that is a little less steep. You prepare it in the evening — when things are easiest — and carry it out in the morning, when they are hardest.

1. In the evening, write down the first step for the next morning — just one, very concrete: “I get up and open the curtains.” Put the note by your bed. In the morning you don’t have to decide, only follow.
2. When you wake, don’t stay in bed with your thoughts. If you notice the review of everything that won’t work has begun, tell yourself: “This is the morning forecast, not a fact.” And take the first step.
3. Go to the light. Open the window, step out on the balcony or in front of the house for five to ten minutes. Daylight is one of the strongest signals for the internal clock.
4. Do something small with your body. A warm drink, a shower, a little stretching. Not because you should, but because the body often pulls mood along with it.
5. In the evening, rate the morning on a scale from 0 to 10 and note what you did. After a week or two you may see that mornings with a first step are at least a point or so easier.

The approach comes from behavioural activation: action comes before motivation, not the other way round. In the morning there will be almost no motivation. But the action can be so small that you can manage it without any.

Other ways to make mornings easier

A few more things people often describe as helpful:

• A fixed rising time, on days off too. Long lie-ins at the weekend shift the internal clock and make Monday even harder.
• Fewer decisions in the morning. Get clothes, breakfast and your bag ready the night before. Every morning decision uses energy you have little of.
• Demanding tasks for when it is easier. If you can, move important conversations and harder work to the afternoon. That is not avoidance but a sensible allocation of strength.
• One person who knows. A partner, friend or colleague who understands that mornings are harder, and who doesn’t comment on you being late but perhaps brings you a coffee.
• Watch the screen in bed. News and social media straight after waking often give rumination fuel.

When it is not that simple

I don’t want this post to sound as if every hard morning is a sign of depression, or as if everything can be solved by opening the curtains.

Not every hard morning is depression. “Night owls” find getting up hard too — people whose internal clock is naturally shifted later, who are sleepy in the morning but not low. The difference is whether the morning heaviness comes with hopelessness, loss of pleasure and a sense of pointlessness.

Morning heaviness can have a physical cause. Sleep apnoea, thyroid disorders, anaemia, alcohol in the evening and some medications — including some antidepressants and sleeping pills — can cause morning grogginess and tiredness. Talk to the doctor or psychiatrist who prescribed your medication about whether the timing affects your mornings. Don’t change anything on your own.

For some people it is worse in the evening. If your mood gets worse over the day rather than better, this post may not describe you. That too is part of the varied picture Wirz-Justice writes about — and it too is worth telling your doctor or therapist.

Morning anxiety is not the same as morning depression. For some people the morning is worst because anxiety kicks in on waking — a pounding heart, a lump in the throat, restlessness. It can overlap with depression, but not necessarily. With anxiety, different approaches often help than with depression.

A better evening does not mean there is no depression. This is perhaps the most important point. If the evening is better, that is not proof that you were exaggerating in the morning. Diurnal variation is part of the picture of depression, not an argument against it.

Where to find help

If your mornings have been starting with heaviness, hopelessness or a sense that the day has no point for weeks, see your GP. They can rule out physical causes and, if needed, refer you to a psychiatrist. A psychiatrist is an important person to turn to in depression — not only because of medication, but because they can assess what kind of help is right for you. Psychotherapy can be part of that help, as it helps you understand what keeps depression going and change the patterns that feed it.

If early mornings begin with thoughts that it would be better if you were not here, don’t wait for it to pass. In Slovenia, call the mental distress helpline on 01 520 99 00 (every day from 7 pm to 7 am), the Samaritan helpline on 116 123 (24 hours a day) or, in immediate danger, 112. These hours can be the hardest — but you are not alone in them.

If in the mornings the pleasure in things that once made you happy disappears too, you may also find Anhedonia: when nothing brings joy any more helpful.

What to remember

• For many people with depression, mood is worst in the morning and eases during the day — this is called diurnal mood variation.
• Behind it are probably the internal clock, the morning rise in cortisol and broken sleep — not laziness or lack of willpower.
• The morning forecast is not a fact: when everything looks black at seven, it is your mood speaking, not the future.
• Small steps decided in advance, light in the first hour and a fixed rising time help.
• If your mornings have been starting with hopelessness for weeks, see your GP or a psychiatrist; if you have thoughts of death, in Slovenia call 01 520 99 00 or 116 123.
