Good night! When is the best time to go to bed..?

There is no single perfect bedtime — but there is a right approach for you. Your ideal bedtime is the one that gives you seven to nine hours of sleep, fits your natural body clock, and stays roughly consistent from night to night. Work backwards from when you need to wake up, pay attention to when you naturally feel sleepy, and prioritise keeping your schedule steady. The specific hour matters far less than whether you can actually stick to it.
