Sleep Better: What is Sleep?

Sleep is a state of calm and vital for all people. When you lie down in your bed and sleep, you come into a changed state of consciousness. Your body is practically in stand-by mode. Your consciousness is switched off, but your brain is permanently active during sleep. Your organism can recuperate and relax in sleep, while it goes through active regeneration phases for your body and a muscle-building state is achieved. This phase of active regeneration also helps to process impressions, experiences and what has been learned and transfers them to long-term memory.1

Neurotransmitters act on different groups of nerve cells called neurons in the brain that control whether we are awake or asleep. The neurons in the brain stem that connect the brain to the spinal cord produce neurotransmitters such as serotonin and norepinephrine that keep some parts of the brain active while awake. The neurons that signal us to fall asleep then switch off the signals that keep us awake.2

the stages of sleep in a sleep cycle

There are five stages of sleep, which are different in depth. These are the 1st, 2nd, 3rd, 4th and the REM (Rapid Eye Movement) phase. The first two phases are characterized by light sleep. Phases 3 and 4 can be combined and are deep sleep phases. The REM phase in which you dream is particularly important. A sleep cycle lasts about 90-110 minutes, of which you have several during the night. Several sleep phases are also passed through in a cycle.

It is best if you always wake up between two phases, as this will make it easier for you to get up. It has probably already happened to you that you have been woken up in the middle of a deep sleep phase and have felt exhausted.

You spend half of your sleep time in phase 2, around 20% in the REM phase and the remaining 30% in one of the other phases.3

Some experts believe that sleep gives neurons the ability to repair themselves while awake.

During sleep, the brain can also train important neural connections that could otherwise deteriorate due to inactivity.

Why better sleep is particularly important for athletes

For those who want to achieve physical and mental performance, sleep is an even more important point. On Lack of sleep can lead to an increased feeling of hungerwhich can cause serious problems, especially in weight-class sports.6 In the case of a lack of sleep, lower leptin levels and an increased ghrelin level were measured. The two hormones are antagonists, with leptin suppressing appetite and ghrelin stimulating appetite.

Furthermore, lack of sleep makes it difficult to burn fat (by 55% with constant weight loss) in obese people.7

Sleep quality appears to be the most susceptible of top athletes, especially before major competition events, during intensive training sessions and after long-distance travel to competitions. Many athletes suffer from the symptoms of insomnia, which can impair training or competitions, for example through fatigue or sleep-related fear of performance.8 Sports performance can therefore be negatively influenced by insufficient sleep. In the worst case, you are not focused or alert during your training, which increases your risk of injury.9

Sleep is therefore not only important to refuel your energy reserves and regenerate your muscles, but also to carry out your training in a focused manner.

The optimal length of sleep

In optimal sleep time is around 7-8 hours. A study from the University of Warwick found that the mortality rate increased by 6% in people who sleep less than 12 hours and by as much as 30% in people who sleep more than 9 hours.10

It was also observed that a variation of the DEC2 gene ensured that people could sleep up to 2 hours less than the average without any problems.

The question of the optimal length of sleep is therefore not easy to answer. In the case of athletes, for example, there may not be enough time to regenerate sufficiently. In a study with college basketball players, for example, improved athletic performance was achieved after 10 hours of sleep.11

Every person should therefore rather sleep a little more than too little during increased physical activity.

Sleep Better: Causes and Symptoms of Lack of Sleep and Sleep Disorders

There are many different causes of lack of sleep and sleep disorders. Often it is due to worries and fears that can not get out of your head and lead to fatigue the next morning. But also stress The increasing demands in our modern way of life or work are causes of difficulty falling asleep and disturbance to sleep, often in combination with long periods of sitting and the use of electronic devices.

The Nation Sleep Foundation surveyed people about their insomnia. Almost half of the respondents suffered from occasional insomnia, 22% even (almost) daily. Within the work week, 15% said they slept less than six hours. 95% of those surveyed use electronic devices several times a week, one hour before going to bed. Artificial light can reduce the quality of sleep by passing through the retina and the suprachiasmatic nucleus, the pineal gland, from producing melatonin.12

The consequences of chronic lack of sleep are probably familiar to many and have already been experienced.

Effects of lack of sleep on your life

A lack of sleep causes more cortisol to be produced, which leads to more cytokines, which are pro-inflammatory. The immune system is weakened and you become more susceptible to colds and infections.13 White blood cells, which are roughly described as important in the defense against infections, are negatively affected. The concentration of C-reactive protein, which is a clue or marker for inflammation, also increases due to lack of sleep in the organism.14

In addition, lack of sleep increases systolic blood pressure and leads to hunger pangs for sugary and fatty foods.

Some people suffer from insomnia caused by nocturnal pauses in breathing (sleep apnea) or restless legs syndrome. But grinding your teeth and sleepwalking can also have an impact on the quality of sleep. When traveling by air to other time zones, jet lag brings the sleep-wake cycle out of balance and your sleep rhythm can be confused for a while.2


Chronic lack of sleep can lead to serious disorders

If the lack of sleep is permanent, the body can suffer more serious damage and possibly promote the following symptoms, e.g.

  • Weight gain15
  • Insulin resistance, which can lead to type 2 diabetes16, 17
  • mental illnesses such as depression18
  • different forms of cardiovascular disease19
  • premature aging
  • memory loss

There are still many questions about the functions of sleep that are still unanswered in sleep research, but it is clear that sleep disorders and lack of sleep can lead to a significant and permanently reduced performance after just a few days. Symptoms such as daytime sleepiness or mood disorders are often made small and overlooked as warning signals. The need for sleep is important for your body because cell renewal processes take place, the immune system is activated, the metabolism is regulated and premature aging processes are prevented.20

In everyday life, sleep is often neglected at work and leisure activities. The negative effects of sleep problems are often not taken as seriously as they should and can lead to serious problems in chronic sleep disorders. But even with short-term lack of sleep, negative effects on your body and your mental well-being can be felt, which shows how important and diverse the sleep functions are. With a few tips you can change your behavior before going to sleep in order to be optimally rested and to start the day with plenty of energy.
