Alarm clock or automatic awakening: which is better

The article discusses the impact of wake-up methods on alertness levels and the transition from sleep to a state of wakefulness in the morning. Research indicates that naturally waking up before the alarm rings may reflect good sleep quality, whereas using an alarm clock can suggest insufficient sleep or a mismatch between sleep timing and an individual's biological rhythm. Experts emphasize that the quality of sleep, its timing, and passage through deep sleep stages play a crucial role in how refreshed a person feels upon waking. Additionally, choosing gentle sounds for alarms or leveraging natural light before relying on sound alone can help reduce sleep inertia. There is no definitive evidence that pressing the "snooze" button increases morning sleepiness, although the timing and type of alarm clock do play an important role. Overall, the best wake-up occurs when a person gets enough sleep that aligns with their natural rhythm, with an emphasis on sleep quality rather than just the number of hours.
