Which symptom is not typically associated with good sleep hygiene?

Engaging in strenuous exercise right before sleep is not typically associated with good sleep hygiene. Good sleep hygiene practices are designed to promote restful and uninterrupted sleep. A consistent sleep schedule helps regulate the body's internal clock, while avoiding caffeine before bedtime reduces the chances of sleep disturbances resulting from stimulants. Creating a restful sleeping environment, such as a dark, quiet, and cool room, is also essential for facilitating sleep.

In contrast, vigorous exercise close to bedtime can lead to increased heart rate, elevated body temperature, and heightened alertness, all of which can interfere with the ability to fall asleep and achieve deep sleep. Therefore, this practice stands out as inconsistent with the principles of maintaining good sleep hygiene.
