How to Get a Good Night's Sleep
Sleep disorders can severely impact physical and mental health if left untreated. Often, individuals experiencing persistent tiredness struggle to identify the root cause, which may stem from an underlying sleep disorder. This article reviews reasons for constant fatigue, the sleep disorders associated with these reasons, common signs of sleep disorders and treatment options available.
Why Am I Always Tired? Common Causes and Related Sleep Disorders
Feeling tired all the time can have different causes, many of which are linked to specific sleep disorders. Below are some of the most common reasons for fatigue and the disorders they may indicate.
1. Poor Sleep Quality
If you wake up feeling unrefreshed, poor sleep quality might be to blame. This could be linked to insomnia, where difficulty falling or staying asleep disrupts restorative sleep cycles.
2. Interrupted Breathing
Frequent pauses in breathing during the night can lead to chronic fatigue. This is a hallmark symptom of sleep apnea, a condition where airway blockages or brain signals prevent proper breathing.
3. Restless Limbs
Uncontrollable urges to move your legs at night can disrupt sleep. This is associated with restless legs syndrome (RLS), which prevents deep, restful sleep.
4. Excessive Daytime Sleepiness
Falling asleep during the day despite adequate nighttime sleep may indicate narcolepsy, a neurological condition that affects the brain’s ability to regulate sleep-wake cycles.
5. Irregular Sleep Schedules
Disruptions in your body’s internal clock, such as working night shifts or traveling across time zones, can lead to circadian rhythm disorders like delayed sleep-wake phase disorder.
6. Chronic Stress or Anxiety
Mental health conditions can interfere with the ability to fall or stay asleep. These issues may contribute to insomnia or nighttime awakenings, perpetuating feelings of fatigue.

Common Signs of Sleep Disorders
Sleep disorders often present with recognizable symptoms, though they vary depending on the specific condition. Being aware of these signs can help in identifying whether you or a loved one might need medical evaluation.
1. Difficulty Falling Asleep
Taking more than 30 minutes to fall asleep regularly may indicate insomnia or other related disorders.
2. Frequent Nighttime Awakenings
Waking up multiple times throughout the night is a key symptom of conditions like sleep apnea, restless legs syndrome or insomnia.
3. Loud Snoring or Gasping for Air
This is often a sign of obstructive sleep apnea, where breathing is repeatedly interrupted during sleep.
4. Excessive Daytime Fatigue
Feeling drowsy during the day, especially when inactive, is a common symptom of narcolepsy, sleep apnea or other disorders affecting sleep quality.
5. Mood Changes
Irritability, anxiety or depression may result from poor sleep or fragmented sleep caused by an underlying disorder.
6. Difficulty Concentrating
Lack of focus or poor memory retention during the day could indicate insufficient restorative sleep caused by a sleep disorder.
7. Restless Legs or Tingling Sensations
Uncomfortable leg sensations or an urge to move them at night can disrupt sleep and indicate restless legs syndrome.
8. Sleepwalking or Talking in Sleep
Engaging in activities while asleep, such as walking or talking, can be a sign of parasomnias, a category of sleep disorders.
Treatment Options for Sleep Disorders
Treating sleep disorders often involves a combination of lifestyle changes, therapies and sometimes medications. Below are the most common treatment options available.
1. Behavioral and Lifestyle Changes
- Sleep hygiene. Establishing a consistent bedtime routine, avoiding caffeine and electronics before bed and creating a comfortable sleep environment can help improve sleep quality.
- Exercise. Regular physical activity can reduce stress and promote better sleep patterns.
- Stress management. Relaxation techniques, such as meditation or deep breathing exercises, can help individuals with insomnia caused by anxiety.
2. Continuous Positive Airway Pressure (CPAP)
For sleep apnea patients, CPAP therapy is highly effective. A machine delivers continuous air pressure to keep airways open during sleep, reducing breathing interruptions.
3. Cognitive Behavioral Therapy for Insomnia (CBT-I)
CBT-I is a structured, evidence-based therapy that helps people identify and change thoughts and behaviors preventing good sleep. It is particularly effective for chronic insomnia.
4. Medications
- Sleep aids. Short-term use of medications like zolpidem (Ambien) or eszopiclone (Lunesta) can help manage insomnia.
- Stimulants. For narcolepsy or excessive daytime sleepiness, stimulants such as modafinil (Provigil) can promote alertness.
- Restless legs syndrome treatments. Medications like dopamine agonists (e.g., ropinirole) can relieve leg discomfort and improve sleep.
5. Bright Light Therapy
For circadian rhythm disorders, bright light therapy helps reset the body’s internal clock by exposing individuals to specific levels of light at the right time.
6. Oral Appliances
Custom-fitted dental devices can help manage mild to moderate sleep apnea by repositioning the tongue and jaw to keep airways open.
7. Surgery
In severe cases of obstructive sleep apnea, surgery may be necessary to remove excess tissue or correct anatomical abnormalities that block the airway.
8. Melatonin Supplements
For circadian rhythm disorders or jet lag, melatonin can help regulate sleep-wake cycles when taken at the appropriate time.
9. Lifestyle Adjustments for Narcolepsy
Narcolepsy patients often benefit from scheduled naps during the day and avoiding heavy meals or alcohol, which can exacerbate symptoms.
When to Seek Help
If you suspect you have a sleep disorder, it’s essential to consult a healthcare provider or sleep specialist. They may recommend a sleep study to diagnose the issue and create a tailored treatment plan.
Sleep is vital for overall health, and untreated sleep disorders can lead to severe complications such as heart disease, diabetes or mental health conditions. Understanding the causes, recognizing the signs and exploring treatment options can significantly improve your sleep quality and overall well-being.
