Sleepiness develops as a result of the body's natural sleep-wake cycle being disrupted. This disruption can be caused by factors such as inadequate sleep, poor sleep quality, irregular sleep patterns, or underlying sleep disorders.

Additionally, certain lifestyle choices, such as excessive caffeine consumption, can also contribute to feelings of sleepiness. **
