Most well-rested adults fall asleep within 10 – 20 minutes of attempting to sleep and spend less than 30 minutes awake during the night.2 Learn more about insomnia
Sleep onset insomnia1,2
People with this type of insomnia have difficulty falling asleep, taking 30 minutes or more to fall asleep. People describe it as “tossing and turning” without being able to sleep. This inability to fall asleep means that you will have a reduced total sleep time and may feel the effects of that lack of sleep the next day.
Sleep maintenance insomnia1,2
In this case, you have difficulty staying asleep through the night. You may wake up at least once during the night and spend 30 minutes or more awake during this time. Fragmented sleep means that your sleep decreases in both quantity and quality, which increases the risk of daytime sleepiness or sluggishness.
Early morning awakening insomnia1,2
Early morning awakening means that you wake up well before you want to in the morning, usually at least 30 minutes before you planned to. Not getting the desired amount of sleep can impair your physical and mental functions the next day.
It is common for people struggling with insomnia to have overlapping sleeping problems. If you have mixed insomnia, you may find that your symptoms shift over time.1
Compromised daytime function2
Insomnia also affects your daytime functioning. Over and above your sleep problems, you may find that you experience2:
- Fatigue (extreme tiredness)
- Poor attention or concentration
- Daytime sleepiness
- Reduced motivation or energy
- Increased errors or accidents
- Ongoing worry about sleep
