Sleep is essential to our health and well-being. Our bodies regulate sleep in the same way they regulate eating, drinking and breathing. Sleep helps the body repair, regenerate and recover from daily activity and injuries. It is also important for our physical and mental functioning, our ability to fight disease and develop immunity, and our metabolism and chronic disease risk.

Sleep helps the body repair, regenerate and recover
Sleep is an essential function that allows your body and mind to recharge, leaving you refreshed and alert when you wake up. Sleep gives your body time to repair itself and carry out important functions, like clearing out waste and releasing hormones. Without these processes, our bodies can’t function correctly. Getting enough sleep is essential for maintaining good health. We need sleep to survive — just like we need food and water. Research suggests that 8 hours of sleep for human beings can produce a daily energy saving of 35% per 24-hour cycle.
The restorative theory states that the body needs sleep to restore itself. Sleep allows cells to repair and regrow. The brain stores new information and gets rid of toxic waste. Nerve cells communicate and reorganise, which supports healthy brain function. The body repairs cells, restores energy, and releases molecules like hormones and proteins. Sleep is important to a number of brain functions, including how nerve cells (neurons) communicate with each other. Sleep also plays a housekeeping role that removes toxins in your brain that build up while you are awake.
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. Research shows that a chronic lack of sleep, or getting poor quality sleep, increases the risk of health problems like high blood pressure, cardiovascular disease, diabetes, depression, and obesity.

Sleep is essential to our physical and mental functioning
Sleep gives our bodies time to repair and carry out important functions, such as clearing out waste and releasing hormones. Without these processes, our bodies can't function correctly. Sleep also supports healthy brain function, allowing nerve cells to communicate with each other and removing toxins that build up while we are awake.
Research shows that a chronic lack of sleep, or poor quality sleep, increases the risk of health problems such as high blood pressure, cardiovascular disease, diabetes, depression and obesity. Sleep also affects our immune function, mood and disease resistance.

Sleep helps our bodies fight disease and develop immunity
Sleep is essential for our bodies to fight disease and develop immunity. Sleep is as important to our health as food, water or air. When we sleep, our brain and body remain active, allowing our bodies to carry out important functions like clearing out waste and releasing hormones. Sleep also supports healthy brain function, including how nerve cells communicate with each other.
Research shows that a chronic lack of sleep, or poor quality sleep, increases the risk of health problems like high blood pressure, cardiovascular disease, diabetes, depression, and obesity. Sleep is also important for our metabolism, immune function, mood, and disease resistance.
The restorative theory states that the body needs sleep to restore itself. Sleep allows cells to repair and regrow. Sleep is also important for our brain function, with the brain plasticity theory suggesting that sleep is required for our brain to function properly.
In summary, sleep is essential for our bodies to fight disease and develop immunity. Sleep allows our bodies to carry out important functions, supports healthy brain function, and helps to maintain our overall health.

Sleep is regulated by our bodies in the same way as eating, drinking and breathing
Sleep is also important for our brain functions, including how nerve cells communicate with each other. 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. Research shows that a chronic lack of sleep, or getting poor quality sleep, increases the risk of health problems like high blood pressure, cardiovascular disease, diabetes, depression and obesity.
The restorative theory states that the body needs sleep to restore itself. The idea is that sleep allows cells to repair and regrow. This is supported by the fact that our metabolic rate drops during sleep, reducing our caloric needs. Research suggests that eight hours of sleep for human beings can produce a daily energy saving of 35% per 24-hour cycle.
The brain plasticity theory also suggests that sleep is required for brain function. Sleep is defined as an altered state of consciousness or a condition of the body and mind where the nervous system is less active, the body is relaxed and consciousness is suspended.

Sleep helps our bodies restore nutrients and clear toxic materials
Sleep is an essential function that allows your body and mind to recharge, leaving you refreshed and alert when you wake up. Healthy sleep also helps the body remain healthy and stave off diseases.

Frequently asked questions
Sleep is essential to every process in the body, affecting our physical and mental functioning the next day, our ability to fight disease and develop immunity, and our metabolism and chronic disease risk.
Our heart rate, breathing, and brain waves slow to their lowest levels, and muscles completely relax. This is the stage of sleep where dreaming and nightmares mostly occur.
When we don't get enough sleep, our body doesn't have the chance to repair and recover from daily activity and injuries.
Sleep helps to strengthen the immune system. Some research suggests that deep sleep is necessary for the body to repair itself and strengthen its immunity.
Our bodies regulate sleep in much the same way that they regulate eating, drinking, and breathing. This suggests that sleep serves a critical role in our health and well-being.
