Stress - Concerns about work, school, health or family can keep your mind active at night, making it difficult to sleep. Stressful life events — such as the death or illness of a loved one, divorce, or a job loss — may lead to insomnia.

Anxiety - Everyday anxieties as well as more-serious anxiety disorders, such as post-traumatic stress disorder, may disrupt your asleep. Worry about being able to go to sleep can make it harder to fall asleep.

Depression - You might either sleep too much or have trouble sleeping if you're depressed. Insomnia often occurs with other mental health disorders as well.
