The reasons for excessive sleep range from neurological disorders and organic diseases to the side effects of certain medications, which can negatively impact daily quality of life.
What are the primary pathological excessive sleep causes?
Oversleeping may not be mere laziness, but rather the result of health conditions that require care, the most important of which are:
- Narcolepsy: A chronic neurological disorder that causes sudden sleep attacks during the day, often appearing between the ages of 10 and 25. It may be accompanied by sleep paralysis or hallucinations and is believed to result from a deficiency of vital proteins in the brain.
- Sleep Apnea: Divided into two types; “central,” which occurs due to a malfunction in brain signals to respiratory muscles, and “obstructive,” resulting from an airway blockage. Both lead to frequent awakenings that reduce sleep quality and increase the need for it during the day.
- Psychological Disorders: Depression is a common cause of hypersomnia due to low energy levels; there is a reciprocal relationship where each affects the other.
- Organic Problems:
- Kidney and Urinary Tract Diseases: These increase the need to urinate at night, interrupting sleep and causing daytime lethargy.
- Thyroid Gland: Hyperactivity may affect the nervous system and sleep quality.
- Medications: Some treatments cause drowsiness, such as antipsychotics, antidepressants, anxiety medications, antihistamines, and blood pressure treatments.
- Other Conditions: Such as “Hypersomnia,” where the desire to sleep during the day increases without satisfaction, or Restless Legs Syndrome, which disrupts sleep at night.
How excessive sleep affects your health
Exceeding the recommended hours (7-9 hours for adults) can lead to health complications:
- Cardiovascular System: The probability of coronary heart disease may increase in women who sleep 9 to 11 hours, and oversleeping is linked to an increased risk of heart attacks.
- Mental and Cognitive Health: It may cause anxiety, accelerate brain aging, and reduce the ability to focus; in severe cases, it may be linked to suicidal tendencies.
- Physical Pain: It leads to increased severity of headaches due to a imbalance in neurotransmitters, as well as worsening back pain.
- Chronic Diseases: Sleeping between 9 and 10 hours increases the chances of obesity and type 2 diabetes.
Does anemia cause sleep disorders?
Contrary to popular belief, anemia does not cause excessive sleep. Instead, research indicates that those affected by it are more prone to insomnia and lack of sleep. This happens because:
- Extreme Fatigue: The body exerts great effort to deliver blood to organs, causing exhaustion that prevents the ability to sleep.
- Anxiety: Iron deficiency leads to an increase in cortisol and a decrease in melatonin, which is responsible for sleep.
- Physiological Effects: Iron deficiency weakens the production of neurotransmitters like dopamine and serotonin that regulate sleep.
When should you visit a doctor?
It is advised to see a doctor immediately when the following signs appear:
- Occurrence of sudden sleep attacks while performing daily activities.
- Loss of control over the sleep system coinciding with symptoms of depression.
- Feeling constant lethargy after starting a new medication.
- Frequent nighttime awakenings accompanied by shortness of breath.
