If you’ve been lying awake at night, unable to drift off no matter how tired you feel, you’re not alone. Millions of people experience sleep difficulties that go beyond the occasional restless night. For many, insomnia is not just a sleep issue—it’s a sign of something deeper. In fact, two of the most common mental health conditions—anxiety and depression—are leading contributors to chronic sleep problems. But how exactly are they connected, and what can you do about it?

Mental health and insomnia are closely connected. Studies have shown that people with anxiety or depression are more likely to suffer from chronic insomnia—difficulty falling asleep, staying asleep, or waking up too early and not being able to fall back asleep.
Insomnia is more than a nighttime inconvenience; it’s often a symptom and a contributor to mental health conditions. If you’re asking yourself, “Can anxiety cause insomnia?” or “Can depression cause insomnia?” the answer is yes—and the relationship goes both ways.
Can Anxiety Cause Insomnia?
Absolutely. Anxiety-related sleep disorders are some of the most common causes of sleeplessness. When you’re anxious, your brain enters a state of hyperarousal, making it nearly impossible to relax or wind down. Racing thoughts, physical tension, and a persistent feeling of unease can keep you up for hours.
Common ways anxiety can disrupt sleep include:
- Ruminating thoughts: Worrying about past events or future responsibilities.
- Increased heart rate or rapid breathing: Physical symptoms of anxiety can mimic stress responses that keep the body alert.
- Panic attacks at night: These can jolt you awake and make it difficult to fall back asleep.
Over time, this cycle can become self-perpetuating. The fear of not sleeping becomes another source of anxiety, deepening the problem.
Can Depression Cause Insomnia?
Yes, depression and insomnia are also deeply intertwined. While some individuals with depression may sleep excessively (hypersomnia), others struggle with falling or staying asleep.
Here’s how depression contributes to sleep difficulties:
- Negative thought patterns can interfere with the brain’s ability to shut down at night.
- Disrupted circadian rhythms, or your body’s natural sleep-wake cycle, often occur in people with depression.
- Low serotonin levels, which affect mood and sleep, are common in those with depressive disorders.
Interestingly, insomnia isn’t just a symptom of depression—it can also be a predictor. Persistent sleep problems can increase the risk of developing depression, even in people with no previous history of the condition.
The Vicious Cycle: Mental Health and Sleep
Insomnia triggered by anxiety or depression often turns into a vicious cycle:
- Anxiety or depression causes sleep problems.
- Lack of sleep worsens mood, concentration, and emotional resilience.
- Poor mental health deepens, which further disrupts sleep.
Breaking this cycle is key to improving both mental health and sleep quality.
Signs Your Insomnia May Be Linked to Anxiety or Depression
How do you know if your sleep issues are tied to a mental health condition? Look for these signs:
- You lie awake for hours, unable to stop overthinking.
- You wake up too early and can’t fall back asleep.
- You experience a heavy or hopeless mood most days.
- You feel anxious during the day and restless at night.
- You dread bedtime due to worry or distress.
If these symptoms resonate, it’s possible you’re dealing with anxiety-related sleep disorders or insomnia linked to depression.
Effective Insomnia Treatment for Depression and Anxiety
Fortunately, there are evidence-based strategies for improving both sleep and mental health. Here are some of the most effective treatments:
1. Cognitive Behavioral Therapy for Insomnia (CBT-I)
CBT-I is the gold standard in insomnia treatment for depression and anxiety. This therapy helps you identify and change negative thoughts and behaviors that contribute to poor sleep.
CBT-I techniques include:
- Sleep restriction therapy
- Stimulus control (e.g., only using your bed for sleep)
- Relaxation training
- Restructuring negative sleep-related beliefs
2. Mindfulness and Meditation
Mindfulness practices like deep breathing, progressive muscle relaxation, and meditation can help calm the mind before bedtime. These are especially helpful for those whose insomnia is fueled by anxiety or racing thoughts.
Apps like Headspace and Calm offer guided sleep meditations tailored for this purpose.
3. Medication (Short-Term Use)
In some cases, your doctor may recommend medication, such as:
- Antidepressants with sedative properties
- Anti-anxiety medications
- Sleep aids (preferably short-term and prescribed with caution)
Medication should be used under close medical supervision and often alongside therapy for best results.
4. Lifestyle Adjustments
- Establish a regular sleep schedule: Wake and sleep at the same times every day—even on weekends.
- Limit screen time before bed to reduce blue light exposure.
- Cut back on caffeine and alcohol, especially in the evening.
- Create a sleep-friendly environment: Dark, quiet, and cool bedrooms are ideal.
5. Seek Professional Help
If you suspect your insomnia is tied to mental health, speak with a licensed therapist, psychologist, or psychiatrist. Treating underlying anxiety or depression can dramatically improve your ability to sleep and your overall quality of life.

When to See a Doctor
You should consult a healthcare professional if:
- Your insomnia lasts more than three weeks.
- You experience symptoms of depression or anxiety daily.
- Your lack of sleep is interfering with work, relationships, or self-care.
- You’ve tried self-help methods with little to no success.
Don’t wait for the problem to resolve on its own. Insomnia is treatable, especially when it’s tied to mental health conditions like anxiety and depression.
Final Thoughts
So, can anxiety or depression be causing your insomnia? The answer is very likely yes—especially if your sleep difficulties are persistent and paired with emotional distress. The good news is that you’re not powerless. With the right support, self-care, and professional guidance, it’s entirely possible to break the cycle and reclaim your sleep.
Prioritize both your mental health and sleep hygiene, and remember: seeking help is a sign of strength, not weakness.
