Can’t Sleep? How Insomnia Can Worsen Anxiety and Depression
Updated: Sep 6
Can’t Sleep? It May Be More Than a Nighttime Problem
If you are lying awake night after night—watching the clock, replaying conversations, or waking with a rush of dread before sunrise—you already know that insomnia is not simply a bedtime inconvenience. It can change how you think, how you feel, and how much capacity you have for the life in front of you.
As an integrative psychiatric nurse practitioner in Syracuse, I often meet people who have been told to “work on sleep hygiene” or take something to help them sleep without anyone asking the more important question: why is sleep disrupted in the first place? Persistent insomnia is often woven into anxiety, depression, trauma, burnout, hormonal shifts, medical conditions, or medication effects. It can be both a symptom and a contributor—not a separate problem to manage in isolation.
A sleep disorder involves a problem with sleep quality, timing, or amount that causes daytime distress or impaired functioning. Sleep difficulties commonly coexist with depression and anxiety, and the relationship runs in both directions. [1]
How Insomnia Affects Anxiety and Depression
Sleep is not “off time” for the brain. Restorative sleep supports emotional processing, stress regulation, concentration, memory, and resilience. When sleep becomes fragmented or insufficient, everyday stressors can feel sharper and harder to manage.
For someone with anxiety, poor sleep may lower the threshold for worry, racing thoughts, physical tension, and panic-like sensations. A person with depression may notice more fatigue, slower thinking, irritability, reduced motivation, and a greater sense of hopelessness after several nights of poor rest. This is not a failure of willpower. It is a whole-body response to an overtaxed system.
The cycle can become self-reinforcing. Anxiety can make bedtime feel like a performance test: “What if I cannot sleep again? What will tomorrow be like?” That fear creates more physiological arousal, which makes sleep less likely. Depression can alter daily structure, energy, activity, and circadian rhythm, all of which can destabilize sleep. Over time, the bed itself may start to feel associated with worry and wakefulness rather than rest.
Not All Sleep Problems Are the Same
“Insomnia” is often used as a catch-all term, but the details matter. Some people cannot fall asleep. Others wake repeatedly, rise much earlier than intended, or spend adequate time in bed yet still feel unrefreshed. A thoughtful assessment should clarify your actual pattern, its timing, and its impact during the day.
Chronic insomnia disorder generally involves difficulty falling asleep, staying asleep, or waking too early at least three nights each week for at least three months, along with meaningful daytime distress or impairment. [1] But persistent sleep disruption can also point toward other conditions that deserve attention, including obstructive sleep apnea, restless legs syndrome, circadian rhythm disruption, substance use, medication side effects, thyroid changes, or chronic pain.
This is why I do not assume that every sleep concern calls for the same supplement, sedating medication, or generic tips. The right plan begins by understanding what is keeping your nervous system awake.
What an Integrative-Functional Sleep Assessment Looks For
In integrative-functional psychiatry, I examine sleep within the full context of your physical health, emotional life, and daily rhythms. A 90-minute intake gives us time to understand the story behind the symptom rather than simply reacting to it.
We may explore stress and trauma history, because a nervous system trained to stay vigilant may struggle to settle at night. We look at mood symptoms, medications, caffeine and alcohol use, movement, screen exposure, and daily structure. When indicated, we also consider contributors such as restless legs symptoms, thyroid concerns, perimenopausal changes, sleep-disordered breathing, or metabolic factors.
I also pay close attention to the gut-brain axis. Digestion, inflammation, meal timing, and the microbiome can influence sleep quality and emotional regulation. This does not mean there is one “perfect” diet or that every sleep problem originates in the gut. It means your biology is connected, and a treatment plan should be curious enough to look for meaningful connections.
Why CBT-I Matters More Than Sleep Tips Alone
Basic sleep habits—consistent wake times, a calming evening routine, and a dark, cool sleep environment—are helpful foundations. However, when insomnia has become chronic, tips alone are rarely enough.
Cognitive behavioral therapy for insomnia, or CBT-I, is a structured, first-line treatment for chronic insomnia. It helps retrain the connection between your bed and sleep, adjust unhelpful patterns around time in bed and napping, and reduce the anxious beliefs that can make sleep feel like a nightly battle. [2] CBT-I is not about trying harder to sleep. In fact, it helps people step away from the effortful struggle that often perpetuates insomnia.
A CBT-I-informed plan may include keeping a simple sleep diary, establishing a consistent wake time, using the bed primarily for sleep, and developing skills to respond differently when sleep does not come easily. It can also include cognitive work around catastrophic thoughts such as, “If I do not sleep eight hours, tomorrow will be ruined.” Research supports CBT-I for improving insomnia and suggests it may also reduce depression and anxiety symptoms when these concerns occur together. [2] [3]
Medication and Supplements: Individualized, Not Automatic
Medication can sometimes be an appropriate short-term part of a sleep plan, particularly when symptoms are severe. It should never be a reflexive, one-size-fits-all decision. Some sleep medications can cause next-day grogginess, tolerance, dependence, or interactions; others may be useful when chosen carefully and reviewed regularly. [1]
The same principle applies to melatonin and other supplements. “Natural” does not automatically mean appropriate, effective, or free of interactions. During psychiatric care, I consider the full clinical picture before making recommendations—and I encourage patients to bring every prescription, over-the-counter medication, and supplement into the conversation.
A More Restorative Way Forward
You do not need to accept exhaustion, dread at bedtime, or a mind that never seems to power down as your permanent baseline. When insomnia and mental health symptoms are treated together, the goal is not merely to sedate the symptom. It is to understand the pattern, restore rhythm, and help your system feel safe enough to rest.
