Napping too close to bedtime
Napping too close to bedtime can interfere with nighttime sleep and reduce sleep quality.
Napping too long
Napping too long can lead to sleep inertia and grogginess upon waking.
Not considering individual differences
Failing to consider individual differences in sleep needs and patterns can lead to ineffective napping strategies.
