Risk factorsBy Mayo Clinic staff
Nearly everyone has an occasional sleepless night. But your risk of insomnia is greater if:
- You're a woman. Women are much more likely to experience insomnia. Hormonal shifts during the menstrual cycle and in menopause may play a role. During menopause, night sweats and hot flashes often disturb sleep.
- You're over age 60. Because of changes in sleep patterns, insomnia increases with age.
- You have a mental health disorder. Many disorders, including depression, anxiety, bipolar disorder and post-traumatic stress disorder, disrupt sleep. Early-morning awakening is a classic symptom of depression.
- You're under a lot of stress. Stressful events can cause temporary insomnia, and major or long-lasting stress, such as the death of a loved one or a divorce, can lead to chronic insomnia. Being poor or unemployed also increases the risk.
- You work night or changing shifts. Working at night or frequently changing shifts increases your risk of insomnia.
- You travel long distances. Jet lag from traveling across multiple time zones can cause insomnia.
