Sleep is a cunning beast: attempts to find out what happens after falling asleep turned to scientists for many sleepless nights. The processes that occur during sleep are incredibly complex; Meanwhile, there is one point with which everyone agrees: sleep is vital for maintaining the functions of the brain and the whole organism. Without it, we would become a zombie (a condition that happens after the “night vigil”).
Sleep gives you the opportunity to recover and be reborn. This is an active process: as long as you dream that you have won the lottery or are swimming in a fountain with champagne, the body supports the activities necessary for life. Sleep affects our speech abilities, concentration of attention – and summarizes everything that we see and hear. The brain carefully filters the information, remembering it and noting emotional details – in order to generate new guesses and ideas. He systematizes everything we learned during the day, setting the senses in motion, and works when we wake up. This is only the psychological aspect of the process, its physical components are also very interesting. The body relaxes, coming to a state of paralysis – to stop active actions in sleep, and the endocrine system (a set of glands that regulate metabolism, growth and recovery) continues to work, producing hormones that support the sleepy state.
Insomnia is one of the most common complaints that doctors hear. 51.3% of the adult population of Great Britain hardly falls asleep at night; every tenth person suffers heavily from insomnia (permanent inability to normal and continuous sleep). Such anxiety disorder is characteristic of every fifth person over six to five years of age. It is not surprising that the Ministry of Health considers insomnia to be one of the main problems of today.
In 2001, the British National Statistical Office conducted a large-scale study, examining the most common health problems among the population of Great Britain; it turned out that sleep disorders and fatigue were much more common than other disorders. Respondents suffering from them also noted that insomnia had a clear effect on their mental and emotional health.
Of course, one cannot say that this is only the problem of Great Britain. Every year, worldwide, the equivalent of billions of British pounds is spent on prescribed medications, not counting other medicines and sleeping pills. Surveys of British society on behavioral risk monitoring (2009) showed that 37.9% of the 74,571 Americans surveyed over the last month at least once involuntarily fell asleep during the day. This not only causes inconvenience (and potentially makes life difficult), but can be very dangerous.
So, a person must sleep. You are programmed to this – and not able to prevent yourself, no matter how hard you try. It is quite dangerous when sleep slips away or you are in a state of constant exhaustion. But – do not panic! This book will help you cope and quickly defeat the problems related to sleep loss and disorders.
