Deep sleep occurs in the latter part of each sleep cycle
Deep sleep is essential for health and wellbeing. Most adults need around 1.5 to 2 hours of deep sleep per night, which equates to about 10-15% of their total sleep time. However, the amount of deep sleep you need can vary based on factors like age and individual differences. For example, adults aged 18-60 are advised to aim for a certain amount of sleep, but this advice does not apply to those younger or older.
To increase your chances of getting the recommended amount of deep sleep, it's best to go to bed between 8 pm and midnight. It usually takes about an hour to enter the deep sleep stage, so the earlier you go to bed, the more likely you are to get the full hour to two hours of deep sleep.
A person cycles through the different stages of sleep 4-5 times every night, and it's important to get a balance of around 25% REM sleep and 25% of the deepest NREM sleep to maintain your health and wellbeing.

To give yourself the best chance of getting the deep sleep you need, it's important to go to bed before midnight. Research shows that sleeping between the hours of 8 pm and midnight sets you up for the best chance at restorative sleep, no matter what time your alarm is set to. It typically takes about an hour to drift into deep sleep, so the earlier you head to bed, the better.
