Understanding Excessively Sleepy
Before we dive deeper, it’s important to understand what “excessive sleepiness” actually means.
What Is Excessive Daytime Sleepiness (EDS)? Excessive Daytime Sleepiness (EDS) refers to the inability to stay awake and alert during the day, even after getting a full night of sleep.

Common Causes of Excessive Sleepiness
1. Poor Sleep Quality
Even if you sleep for eight hours, poor-quality sleep can leave you exhausted. This is one of the most common causes of too much sleepiness.
What affects sleep quality?

3. Lifestyle-Related Causes Lifestyle factors are often overlooked, but they contribute heavily to causes for too much sleepiness.

Deeper Look: Why Your Body Wants More Sleep
Your Circadian Rhythm Might Be OffYour body has a natural internal clock. When disrupted, it creates powerful urges to sleep during the day.
What disrupts circadian rhythm?
Night shift work
Jet lag Irregular bedtimes

Hormonal Imbalances
Hormones influence energy levels and alertness.
Key hormones linked to sleep:
