Sleep is gold! That is more than that. Sleep is what gives new energy to the tired body after the whole day's work. It is the key to keeping thoughts flowing properly and improving health. If you do not sleep properly for a long time, the body collapses. It becomes a pile of diseases like high blood pressure and diabetes. Being swept up in the modern lifestyle, many people are getting these diseases. If you act with a bit of wisdom, you can drive away insomnia and diseases, caused by it.
Sleep is the most important and greatest gift that God has given us. Many things are done throughout the day. The organs of the body get tired after working. In this way, the body recovers the energy spent in the processes that take place in the body during sleep. Sleep is very important for the brain to regain energy and concentration, for us to learn, for what we have learned to be stored in the brain, and for us to remember.

The sleep process and the actions in our brain are coordinated by EEG (Electro Encephalogram). Sleep can be divided into two parts. 1. Non-rapid eye movement (NREM) sleep. 2. Rapid eye movement- REM) sleep. These come in cycles one after the other. Each cycle takes about 30 minutes. A night's sleep lasts up to 4-5 cycles. Usually, sleep begins with NREM sleep. It is called slow-wave sleep. It consists of four stages. These come one after another. This sequence is also called the sleep and wake cycle. Before falling asleep, we keep noticing being a little tired, not feeling like working, yawning, and feeling like not going to sleep. At this time, sleepiness prevails. It is the first stage.
