How the body changes during sleep

The body is like a machine that processes and distributes information in a way that changes over time.

A little bit goes a long way, and a little bit is enough.

This is why we sleep at night.

There are various types of sleep that are different, but the body’s ability to process information and use it to build muscles and organs is essential to its functioning.

This article is part of BBC Sport’s Sportweek special series, where we look at some of the big issues of our time.

This week: How sleep is affected by our mood and health sleep is the key to our health and wellbeing and a key part of our physical and mental wellbeing, according to scientists.

Sleep is a slow process that is designed to protect against the effects of stress and disease, as well as helping the body to heal and maintain its health.

It helps to maintain our body’s structure, which helps regulate the flow of blood throughout the body and provides the body with energy.

This process of sleep is also called deep sleep.

It is the period when most of our body and brain functions are suspended during the day.

The brain, for example, is asleep during the night.

The process of falling asleep is called hypnagogia.

It occurs when our brain doesn’t know how to process the information that is presented to it.

When this happens, the body is unable to recognise and process what it has just experienced.

A person who has difficulty falling asleep, or who is otherwise not at full capacity during the daytime, may not feel as energised as a person who is in a normal sleep state.

People who experience these difficulties will often sleep for longer periods of time than normal people.

What this means is that, over time, they may lose the ability to concentrate on their work or school, which can lead to poor mood, and make them more anxious.

Sleep has a long history in human history and we have long recognised its importance in our health.

Our ancestors would have slept during the winter months, which are usually very cold and dark, and would have had trouble concentrating on tasks such as writing letters or studying.

Some of the most famous examples of early sleepwalking are attributed to Alexander the Great, who was known to have slept for hours on end, and to Christopher Columbus, who slept for up to 12 hours a night for two months.

But it wasn’t until the 20th century that sleepwalking was recognised as a medical condition, and was finally officially recognised by the World Health Organisation in 1994.

The first study on sleepwalking in humans involved 40 subjects, aged between 20 and 40, who were given a battery of tests to measure their sleep.

They were given different drugs to see how they reacted to different types of drugs, including benzodiazepines, which inhibit sleep and can be fatal, and barbiturates, which affect the brain and may lead to a coma or death.

The drug-induced sleepiness was much worse than the other treatments, with the subjects having a mean of 16 hours of sleep deprivation per night, compared with a mean sleepiness of just under 8 hours in the placebo group.

Sleepwalking can be an anxiety-provoking experience for people, as it involves a loss of control over your breathing and movements.

When you are awake, your body releases chemicals that help it regulate the amount of oxygen in your blood, which allows your body to maintain a healthy rhythm and breathing.

If your body becomes sleep deprived, this can cause you to have a loss in your alertness, which in turn may result in a lack of energy.

For some people, this is an extremely stressful and damaging experience, but for others it can be a great source of joy and happiness.

As well as causing a loss to your energy levels, it can also help you focus on your task, which is important in terms of your concentration and memory.

For example, if you are a good student, this may mean you concentrate better on your study, which will help you to complete your homework.

But if you have a lack the energy to concentrate, then you may be more easily distracted by the fact that you are sitting at home, which makes you more likely to fall asleep and feel exhausted.

If you’re experiencing this kind of stress during your day, there are a number of options available to help.

Some people may use alcohol or drugs to try and ease the pressure of being awake all day, but these are usually not effective.

Sleep aids are also available, such as deep breathing, which help to reduce anxiety and make you feel more relaxed.

The use of drugs and alcohol to try to make you sleep better is one way that people try to get you to fall into a routine that will help them sleep better.

This can be particularly helpful if you need to sleep during the summer months when it’s hotter and your body has a lot of heat to dissipate.

If there is no alternative to staying up, it may be helpful to take a few short naps to help you feel a little less stressed
