Restless Legs Syndrome
This condition causes uncomfortable sensations in your legs, such as tingling or aching. These sensations give you the urge to make your legs move frequently, including while resting, which can interrupt your sleep.
Delayed Sleep Phase Disorder
Delayed sleep phase disorder is another condition that can affect sleep. This condition causes a delay in the 24-hour cycle of sleep and wakefulness. You may not feel sleepy or fall asleep until the middle of the night. This sleep cycle makes it harder for you to wake up in the early morning and leads to daytime fatigue.
When To Screen Yourself For A Sleep Disorder
If you are complaining of daytime sleepiness and tiredness, or if you are having difficulty sleeping at night, you may have an undiagnosed sleep disorder.
