What causes sleepiness during the day?

Daytime sleepiness can be caused by various factors, including insufficient sleep at night, disrupted sleep patterns, or sleep disorders such as sleep apnea. Additionally, stress, poor diet, and a sedentary lifestyle may contribute to feelings of fatigue. Certain medications and underlying health conditions can also play a role in increased daytime drowsiness. Ultimately, maintaining good sleep hygiene and addressing any underlying issues are essential for reducing daytime sleepiness.
