Sleep is an essential part of our daily routine. It is as important to our survival as food and water, and it affects almost every type of tissue and system in the body. Most healthy adults need at least seven hours of sleep each night, but some people may need eight or nine hours. Too little sleep can have serious health consequences, including a higher risk of chronic diseases and early death.

What You'll Learn
The minimum amount of sleep for adults is seven hours
Sleep is an important part of our daily routine. We spend about one-third of our time doing it, and it's as essential to our survival as food and water. Sleep affects almost every type of tissue and system in the body, from the brain, heart, and lungs to metabolism, immune function, mood, and disease resistance.
Too little sleep can affect your body's systems and restorative functions. Ongoing sleep deprivation has been linked to serious health consequences, including a higher risk of chronic diseases and early death.
To evaluate your sleep needs, consider how you feel when you get different amounts of sleep. Ask yourself questions like, "Do I feel rested after seven hours of sleep, or do I need at least eight or nine?" By paying attention to your body and making adjustments as needed, you can ensure you're getting the optimal amount of sleep for your health and well-being.

Lack of sleep can affect your body's systems and restorative functions
Sleep is an essential part of our daily routine, and it's as important to our survival as food and water. While we sleep, our body powers down and most body systems become less active. This allows our body to heal injuries and repair issues that happened while we were awake. Sleep is also when our body removes toxins from our brain that have built up while we were awake.
The amount of sleep we need varies depending on our age and individual needs. The Sleep Health Foundation recommends 9-11 hours for school-age children, 8-10 hours for teens, 7-9 hours for adults aged 18-64, and 7-8 hours for older adults (65 and over).
If we don't get enough sleep, our body's systems and restorative functions can be affected. Sleep deprivation can have negative effects on multiple body systems, organs, and processes. For example, it can have long-term damaging effects on your heart and circulatory health, increasing your risk of high blood pressure and high cholesterol. Sleep deprivation can also affect your metabolic systems, with people who don't get enough sleep being at a much higher risk of developing Type 2 diabetes.
Sleep is also important for our immune system. Our body's natural defences against infections can't work properly if we aren't getting enough sleep. Sleep is necessary for the production of the hormone melatonin, which protects against inflammation. If we don't get enough sleep, that inflammation can linger after we wake up, and long-term, systematic inflammation is associated with a host of health issues, including diabetes, cardiovascular disease, and even depression and cancer.
Finally, sleep is important for our nervous system. Sleep deprivation can increase our pain sensitivity, making us feel pain more easily or more intensely. It can also disrupt how our body usually sends and processes information, making it harder to concentrate or learn new things.

Sleep is as essential to survival as food and water
Most healthy adults need at least seven hours of sleep each night. However, this can vary from person to person, and some people may need eight or nine hours to feel rested. Infants, young children and teenagers should get more sleep to support growth and development.
Sleep is important to a number of brain functions, including how nerve cells (neurons) communicate with each other. Recent findings suggest that sleep also plays a housekeeping role that removes toxins in the brain that build up while you are awake.
The occasional night of poor sleep won't seriously impact your health, but ongoing sleep deprivation has been linked to serious health consequences, including a higher risk of chronic diseases and early death.

Sleep is important for brain function
Sleep is important for the brain's ability to form and maintain pathways that allow us to learn and create new memories. Without enough sleep, it becomes harder to concentrate and respond quickly. Sleep also affects how nerve cells (neurons) communicate with each other.

Sleep deprivation can lead to serious health consequences
Sleep is an essential part of our daily routine, and it is as important to our survival as food and water. Most healthy adults need at least seven hours of sleep each night, but this can vary from person to person. Sleep deprivation can lead to serious health consequences, including a higher risk of chronic diseases and early death. Lack of sleep can affect your body's systems and restorative functions, including your brain, heart, lungs, metabolism, immune function, mood, and disease resistance. It can also make it harder to concentrate and respond quickly, as it impacts the way your nerve cells communicate. Poor quality sleep can worsen existing health and mental health conditions, such as depression, and fuel a cycle of sleeplessness.
