The exact amount of sleep needed will depend on factors such as activity level, health status, genetics, and more.
To maintain a healthy lifestyle, adults should get at least 7-9 hours of sleep each night, according to recommendations from the US Centers for Disease Control and Prevention.
Poor sleep schedules — especially among teens and young adults — are a growing problem. While sleep deprivation can lead to fatigue or drowsiness, chronic lack of sleep can lead to more serious health problems. Various scientific studies have now found that poor sleep habits can lead to serious health problems and chronic diseases such as obesity, brain function and lifestyle disorders, among other diseases.
According to guidelines from the US Centers for Disease Control and Prevention, adults should sleep for at least 7-9 hours each night for a healthy lifestyle. Babies, children and adolescents need more hours of rest as they are in their growth and developmental stages. 7-8 hours of sleep is enough for people above 65 years of age. The exact number of hours of sleep will be based on factors such as activity level, health status, genetics and more.

importance of deep sleep
The quality of your sleep is just as important as the number of hours you spend snoozing. If you wake up feeling tired and nervous, the quality of your sleep may be compromised. This may be the result of not spending enough time in the different stages of sleep. Each phase of your sleep cycle has different benefits. The most important stage of sleep to feel healthy and refreshed is deep or REM (Rapid Eye Movement) sleep.
Deep sleep is the state of sleep where your body repairs itself and builds up energy for the next day. During deep sleep, your brain also clears out chemical byproducts that have accumulated throughout the day. Waking up in the middle of a deep sleep can make you nervous and not getting enough deep sleep can be equally painful. Since your sleep states usually occur in periodic cycles that last about 90 minutes, you should try to wake up at the end of the deep sleep cycle.
