For most adults, including adolescents, the best time for sleep depends on individual factors such as age, occupation, health problems, and how much they have to do the next day.
Thousands of respondents have shared their sleep regimen habits. The most popular responses are by far “usually between 8pm or 9pm”and “right after dinner.” Interestingly enough though, these are not statistically significant differences. According to our data set 94% of people answer this with a range of 8PM-11Pm! Moreover 84% of which say that they go bed before midnight with most common being around 10PM-1030PM. From this data it is clear that the most optimal time for most adults is dependent on individual factor.
