Each cycle contains four individual stages: three that form. Ideally, you need four to six cycles of sleep every 24 hours to feel fresh and rested. Most people need 79 hours of sleep per night, but working out how much deep sleep. An average sleep cycle lasts about 90 minutes. If you’re sleep deprived, even from just one night, you should consider postponing or rescheduling anything that could be dangerous until you have slept and feel rested. Slow wave or deep sleep is a stage in the sleep cycle needed for proper brain function and memory.

This is because you will get one full sleep cycle in and will likely wake up when you're about to go from REM sleep to a light sleep, leaving you more alert and refreshed. When your body is sleep-deprived, you could experience microsleeps or short lapses in consciousness that can have dangerous consequences. If you have two hours available to you, sleep for 90 minutes instead of the full two hours.
We want to be clear in saying that getting 90 minutes of sleep isn’t preferable to a full 8 hours, especially if you’re going to be driving or working in a high-risk environment. For example, sleepiness while driving is responsible for car crashes and serious wrecks, and in older people, sleep deprivation is linked to an increased risk of falling and breaking bones 4. Plus, even short-term sleep deprivation is linked to an increased risk for injuries in adults and teens as it can compromise our ability to make decisions and even our motor function. This is because consistent sleep deprivation can cause a myriad of chronic health issues in people over time. Babies typically sleep about 16 hours a day. Some research suggests that lost sleep can take years off your life and that you may not be able to catch up on the lost hours of rest. Consequently, they may have been awake several hours before they go to work and may not perform well or be alert. Although personal needs vary, on average, adults need 7 to 8 hours of sleep per night. We do not recommend sleeping for only one hour at night. What you eat and drink during the day can either help or hurt your prospects of a good nights rest.
