The two-way relationship between insomnia and depression magnifies their impact on your emotional, mental, and physical well-being. Each one directly influences the other. Depression can cause insomnia and insomnia leads to depression.
At the same time, treating one also improves the other.
Nearly half of people with insomnia are also depressed, while 80-90% of those diagnosed with depression have insomnia. The two conditions are so connected it’s often hard to tell which one came first or whether you have insomnia, depression, or both.
You don’t need to figure out which condition is responsible for your low energy, foggy brain, and depressed mood. You can depend on the empathy and skill of Kevin Joseph, DNP, PMHNP-BC, at Insight Psychiatric Services to navigate both conditions, identifying your sleep and mental health needs and creating a customized care plan that helps you overcome both.
Let’s look at how each condition affects the other and the treatments that can help.
Lack of sleep causes anxiety, affects your physical and mental performance, and makes it hard to cope with daily life. As a result, you feel stressed, worthless, tired, and down — putting you on the edge of depression.

Insomnia is one of the earliest and most common symptoms of depression. Depression may cause insomnia through several pathways, including:

When you’re depressed, you may engage in behaviors that affect your sleep, such as watching TV or using your computer at night. Electronics send out blue light that disrupts your sleep-wake cycle.
You may consume more caffeine in an effort to boost the low energy caused by depression. Or depression may make you turn to alcohol, which also affects your sleep.
Many people with depression think about their problems or struggle with negative thoughts when they lay down to sleep. In addition to affecting your sleep, these ruminations make bedtime a stressful event, further contributing to insomnia.
Dr. Joseph offers patient-centered care, creating individualized treatment plans that meet each person’s mental health needs. As a specialist in medication management, he may recommend antidepressants or medication targeting your insomnia.
Antidepressants restore serotonin levels, which may improve depression and insomnia. Though several sleep medications are available, cognitive behavioral therapy for insomnia (CBT-I) is considered to be the most effective treatment for insomnia.
CBT-I is a time-limited therapy that incorporates a range of techniques, including:
