Insomnia is defined as any or all of the following; trouble falling asleep, staying asleep, waking too early, or feeling tired during the day. The constellation of symptoms that you struggle with will impact which treatments work best.
The term sleep maintenance insomnia, also known as middle insomnia, refers to the challenge of staying asleep throughout an entire night. This is defined as waking up during the middle of the night and finding it hard to fall back to sleep once you do wake up. This type of awakening can happen multiple times throughout the night, leading to fragmented and insufficient sleep.

The main symptom and indicator of sleep maintenance insomnia is waking up during the middle of the night and having a hard time going back to sleep. Other symptoms are sleep anxiety, daytime sleepiness, inability to concentrate, headaches, and irritable mood.
Impact of Sleep-Maintenance Insomnia
Living with insomnia is hard. In addition to the long, frustrating sleepless nights, it also can affect both mental and physical health.
Short-term consequences include the inability to function and perform. It lowers reaction time which means routine tasks such as driving become unsafe. Further, studies show that it can also affect balance.
What Can Cause Sleep-Maintenance Insomnia?
Waking up during the night is normal; most of us do. However, we do expect to have the ability to fall back to sleep fairly quickly. So if you find yourself waking up and having difficulty going back to sleep, for at least three out of seven nights per week, for three months or more, you are likely struggling with sleep-maintenance insomnia.
It can be helpful to consider all the factors that may be creating this frustrating cycle such as:
- Physical factors such as pain, breathing or digestive problems, hormones, or a full bladder
- Psychological factors such as stress, anxiety or other psychological concerns (mood disorders)
- Sleep Habits such as your sleep schedule, caffeine, nicotine, or alcohol intake, or technology habits
Sleep-Maintenance Insomnia Treatment
Sleep-maintenance insomnia, like other forms of insomnia, is treatable. Most people can benefit by adopting healthy lifestyle habits. such as exercising regularly and establishing a relaxing bedtime routine. Resisting daytime naps and going to bed only when sleepy is also recommended, as is avoiding stimulants such as caffeine before bed.
Sleep-maintenance insomnia often develops because we have taught our brains to respond to natural wake-ups with hyperarousal. We worry about being awake during the middle of the night. To unlearn this and train your brain not to be afraid, we can use a user-friendly behavioral techniques from CBT-I such as stimulus control.
Cognitive Behavioral Therapy for Insomnia (CBT-I) can help if insomnia persists. It is a proven therapy that directly addresses the link between thoughts, behaviors, and habits. It enables you to form healthier habits and cope with stress and the negative thoughts associated with insomnia. These, as discussed earlier, are the common causes of a chronic sleep=maintenance insomnia pattern.
