What Are Sleep Diseases?
Sleep diseases are conditions that interfere with your ability to get enough restful sleep and maintain healthy sleep patterns. There are more than 80 different sleep diseases, and they affect:

What Are the Major Categories of Sleep Diseases?
The classification of sleep diseases has changed several times over the years. The International Classification of Sleep Disorders (ICSD) currently groups sleep diseases based on symptoms, how they affect the body (pathophysiology), and the body systems involved.
The most recent update, ICSD-3R, includes the following categories:
- Insomnia – Difficulty falling asleep or staying asleep
- Sleep-related breathing disorders – Breathing problems that occur during sleep
- Central disorders of hypersomnolence – Difficulty staying awake or feeling alert during the day
- Circadian rhythm sleep-wake disorders – Problems caused by an internal body clock that disrupts sleep and wake times
- Parasomnias – Unusual physical behaviors or verbal expressions during sleep, such as sleepwalking or sleep talking
- Sleep-related movement disorders – Repetitive movements or urges to move that interfere with sleep
The ICSD is updated regularly to include the latest research and information about sleep diseases.
How Much Sleep Do I Need?

Diagnosis and Tests
How are sleep disorders diagnosed ?
A healthcare provider diagnoses sleep diseases through a physical examination, symptom review, and diagnostic testing. Tests may include blood tests or imaging studies to identify underlying causes.
Your provider may ask you to maintain a sleep journal to track your sleeping habits. In this journal, you should record:
- The time you go to bed
- The estimated time you fall asleep
- The time you wake up
- Any daytime naps
- How you feel before and after sleeping
Keeping a pen and paper near your bed can help you record details accurately. Since it can be difficult to know the exact moment you fall asleep, estimating the time is acceptable.
Some people use smartwatches or wearable devices called actigraphs to monitor sleep and activity cycles. These devices help confirm sleep and wake times.
Your primary care provider may also refer you to a sleep specialist for a sleep study (polysomnogram). During this test, medical professionals electronically record brain activity, breathing patterns, heart rate, and body movements while you sleep. A healthcare provider analyzes the results to determine whether a sleep disorder is present.
What Questions Will Your Healthcare Provider Ask During a Sleep Test?
During a sleep assessment, your healthcare provider asks specific questions to understand your sleep habits, lifestyle, and possible sleep disorders.

How Can I Get Better Sleep?
Healthcare providers often recommend improving sleep hygiene to help you sleep better. Sleep hygiene focuses on creating a routine and environment that support restful sleep.
You can improve your sleep by:
Creating a Comfortable Sleep Environment
Keep your bedroom cool, quiet, and dark. If noise disrupts your sleep, use white noise or earplugs. If light interferes, use a sleep mask or blackout curtains.
Managing Stress Before Bed
Reduce stress before bedtime by writing down tasks or worries earlier in the evening. This habit helps prevent overthinking at night. Try to maintain a positive mindset rather than worrying about the effects of poor sleep.
Using Your Bed Only for Sleep
Avoid watching television, using your phone, eating, or working in bed. Reserve your bed for sleep and intimate activities only.
Establishing a Consistent Bedtime Routine
Create calming habits before bed, such as taking a warm bath, listening to soothing music, or reading. Practice relaxation techniques or meditation. Wake up at the same time every morning, including weekends and holidays.
Avoiding Clock-Watching
Turn clocks away from view and place your phone face down. Use it only as an alarm. If you cannot fall asleep within 20 minutes, leave the bedroom and engage in a relaxing activity without screens until you feel sleepy.
Exercising Regularly
Exercise regularly to support healthy sleep, but avoid exercising within four hours of bedtime if you struggle to fall asleep. Avoid intense workouts close to bedtime.
