Sleep is essential for our bodies to function correctly. While we sleep, our body repairs itself, restores energy, clears out waste, and releases hormones. Sleep also allows the brain to store new information and get rid of toxic waste. The brain and body slow down and engage in processes of recovery, promoting better physical and mental performance the next day. Sleep is also important for conserving energy. The amount of energy we use during sleep depends on factors such as our basal metabolic rate (BMR) and weight.
| Characteristics | Values |
|---|---|
| Repairing and restoring the body | Sleep allows the brain and body to slow down and engage in processes of recovery, promoting better physical and mental performance the next day and over the long term. |
| Conserving energy | Sleep helps the body conserve energy by reducing caloric needs and lowering metabolism. |
| Maintaining overall health | Sleep is vital to our overall health, and without it, our bodies cannot function correctly. |

Sleep allows the body to repair itself and carry out important functions, like clearing out waste and releasing hormones
Sleep is essential for maintaining good health and is just as important as food and water. During sleep, the body undergoes a series of changes that enable the rest that is vital to our overall health. The brain and body slow down and engage in processes of recovery, promoting better physical and mental performance the next day.
Sleep allows the brain to store new information and get rid of toxic waste. Nerve cells communicate and reorganise, supporting healthy brain function. The body repairs cells, restores energy, and releases molecules like hormones and proteins.
If you exercise during the day, your muscles will recover and repair themselves at night, which requires energy. Food digestion also uses energy, as your body breaks down your meal into usable fuel for the following day. The amount of energy you use during sleep depends on a number of factors, including your basal metabolic rate (BMR), which determines the amount of energy your body needs to maintain its most basic functions, such as breathing, blood circulation, and keeping your organs running.
Research suggests that eight hours of sleep for human beings can produce a daily energy saving of 35% per 24-hour cycle. This is supported by the restorative theory, which states that the body needs sleep to restore itself, and the brain plasticity theory, which says that sleep is required for brain function.

Sleep is required for brain function
Sleep is also when the body repairs cells, restores energy, and releases molecules like hormones and proteins. 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 states that sleep is required for brain function. This theory is supported by the restorative theory, which states that the body needs sleep to restore itself. Sleep allows cells to repair and regrow.
The energy conservation theory also suggests that we need sleep to conserve energy.

Sleep helps conserve energy
Research suggests that eight hours of sleep for human beings can produce a daily energy saving of 35% per 24-hour cycle. This is because our metabolic rate drops during sleep.
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.
If you exercise during the day, your muscles will recover and repair themselves at night, which requires energy. Food digestion also uses energy, as your body breaks down your meal into usable fuel for the following day.

Sleep improves physical and mental performance the next day
Sleep gives the 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.

Sleep helps the body recover from exercise
If you exercise during the day, your muscles will recover and repair themselves at night, which requires energy. Sleep also allows the brain to slow down and engage in processes of recovery, promoting better physical and mental performance the next day and over the long term.
Sleep is essential for maintaining good health, and we need it to survive, just like we need food and water. Getting the sleep we need—seven to nine hours for adults and even more for children and teens—is crucial. Without enough sleep, our bodies cannot function correctly, and our thinking, concentration, energy levels, and mood are affected.
The restorative theory states that the body needs sleep to restore itself. Sleep allows cells to repair and regrow, and the brain to store new information and get rid of toxic waste. The brain plasticity theory also supports the idea that sleep is required for brain function.

Frequently asked questions
The body needs fuel during sleep to carry out important functions, such as repairing cells, restoring energy, releasing hormones and clearing out waste.
The body uses fuel during sleep to maintain its most basic functions, such as breathing, blood circulation and keeping organs running.
The amount of fuel the body uses during sleep depends on a number of factors, including your basal metabolic rate (BMR) and how much you weigh.
Sleep is vital to your overall health, and without it, fundamental processes are short-circuited, affecting thinking, concentration, energy levels and mood.
If the body doesn't have enough fuel during sleep, it won't be able to carry out important functions and processes, which can lead to negative health consequences.
