Sleep is essential for health, renewal, learning, and memory. While seven to nine hours of sleep per night is recommended, the bare minimum of sleep needed to survive is four hours per 24-hour period. However, functioning well on four to five hours of sleep is challenging, and less than six hours can negatively impact mental state and happiness.

What You'll Learn
The bare minimum of sleep needed to live is 4 hours per 24-hour period
Most sleep experts recommend getting somewhere between 7 and 9 hours of sleep per night. This amount of sleep is needed for health, renewal, learning, and memory. Getting less than 7 hours of sleep per night can have negative consequences, including a degraded mental state in terms of happiness, concentration, and information retention.
Shift workers, for example, average only about 5 or 6 hours of sleep per night. These disruptions to their sleep cycles can contribute to symptoms such as shallow and/or fitful sleep, headaches, difficulty concentrating, and upset stomach. Shift workers typically have weaker immune systems and are more likely to experience emotional problems and social handicaps.
Therefore, while it may be possible to survive on 4 hours of sleep per night in the short term, it is not recommended as it can have negative consequences for your health and well-being.

Seven hours is the minimum for a regular sleep schedule
If you're in special circumstances, you should aim for 5.5 to six hours each night. This will allow you to log some deep sleep. However, anything between five and seven hours isn't great but will do if it's just a night or two. Anything less than five hours, for any length of time, can have serious consequences.
The bare minimum of sleep needed to live, not just thrive, is four hours per 24-hour period. However, you need to sleep to retain knowledge, and anything less than six hours can start to degrade your mental state in terms of happiness, concentration, and information retention.

It is important to note that restricting sleep to study or work is not advisable as it can lead to failure and a degradation of your mental state. While you may be able to survive on 4 to 5 hours of sleep for a short period, it is not sustainable in the long term and will likely result in negative consequences for your health and well-being.
