We all experience fatigue and exhaustion at some point— that overwhelming desire to transform your “to-do” list into a “do-nothing” list and simply take a nap. However, if you constantly struggle to stay awake during the day, it could be more than just tiredness. Excessive daytime sleepiness (EDS) is a medical condition where the need for sleep is so intense that it hinders daily activities, even if you’ve had sufficient sleep at night, according to a May 2021 clinical review in Mayo Clinic Proceedings. The review suggests that as many as 1 in 3 U.S. adults report grappling with excessive sleepiness during the daytime.
“Excessive daytime sleepiness is a specific medical term for a strong desire or likelihood of falling asleep,” explains Dr. Anne Marie Morse, a board-certified pediatric neurologist with expertise in sleep medicine. EDS can impact mood, memory, focus, attention, and productivity, leading to a significant decrease in quality of life and an increased risk of accidents and other health conditions, as noted by the NHS.
EDS is usually a symptom of an underlying condition and requires medical expertise to diagnose and treat properly. Insufficient sleep is a common cause of EDS, with approximately 40% of adult Americans chronically sleep-deprived. There are two types of EDS: primary and secondary. Primary EDS is not linked to another medical issue and often involves disruptions in the brain and nervous system responsible for sleep regulation. Secondary EDS, on the other hand, is more prevalent and can be caused by various medical conditions, medications, or lifestyle factors.
Differentiating between fatigue and EDS is crucial. While fatigue can leave you feeling physically and mentally worn out, EDS involves a persistent need for napping throughout the day, even after a full night’s sleep. EDS can lead to social, professional, and health difficulties, including an increased risk of accidents and other serious health conditions. If you suspect you may have EDS, it’s essential to seek medical help to determine the root cause and receive appropriate treatment.
Diagnosing EDS involves keeping a symptom diary and discussing your sleep patterns with a healthcare provider. Treatment for EDS varies depending on the underlying cause and may include lifestyle changes, medications, or other interventions. Don’t delay seeking help if you suspect you have EDS, as timely diagnosis and treatment are crucial for managing this condition effectively. Remember, self-curing EDS is not recommended— always consult a healthcare professional for proper evaluation and care.
