Short-term insomnia is often associated with the stress you face in daily life. You may have problems on the job, a sick family member, a relationship that’s on the rocks, or money problems.
You could also have habits that affect your sleep. Consuming caffeine late in the day, drinking alcohol close to bedtime, and light from the TV and computer can all disrupt your sleep.
Causes of chronic insomnia may be medications or underlying health conditions, such as:
- Sleep apnea
- Heart failure
- Chronic pain
- Restless legs syndrome
There’s also a two-way relationship between mental health disorders and insomnia. Lack of sleep significantly increases your risk of developing mental health conditions.
At the same time, having a psychiatric disorder often causes insomnia. Half of all cases of insomnia are associated with depression, stress, and anxiety.
