Snoring is the vibration of respiratory structures and the resulting sound, due to obstructed air movement during breathing while sleeping. The sound may be soft or loud and unpleasant. Snoring is known to cause sleep deprivation to both the snorer and those who hear him/her, as well as knock-on effects: daytime drowsiness, irritability, lack of focus, decreased libido. It has also been suggested that it can cause significant psychological and social damage to sufferers.
Sleep apnoea is a condition that interrupts your breathing when you are asleep. This is usually caused by an obstruction blocking the back of the throat so that the air cannot reach your lungs. The cessation of breathing automatically forces you to wake up in order to start breathing again. This can happen many times during the night, making it hard for your body to get enough oxygen, and preventing you from obtaining enough good quality sleep.

The Stages of Sleep

asleep is not a step. There are many stages in the sleep cycle, and the different processes in each. In the science is still searching for the true meaning and purpose of sleep, many answers can be found in the stadiums. Of course, why the steps, there is another task in itself, but fortunately it is not something that we have reason for concern.

When we are awake, our brains with a kind of wave, as beta waves. This allows us to quickly and operate as we have. The first phase of sleep with a transition from beta waves to alpha waves, a little slower and can be achieved by simple relaxation, even if they do not sleep. It is also during this phase, the Ruck hypnic may occur in which the brain is wrong muscle relaxation, and causes the limbs to move suddenly.

Level two is an interesting phase, because there are two unique features that no other platform has. The first is the sleep-spindle, the fast, rising increase in the amplitude of brain waves. The second is the K-complex, with sharp drops and rises in amplitude. More Theta waves (the next nature, alpha) are now in the whole brain.

phase three, the delta wave, are still slower than theta. This phase is what most people see as deep sleep, and it is here that you're not just woken up. Level four is identical to the third stage, with the exception of Delta facilities are ubiquitous in various parts of the brain.

All Levels up to now were NREM, or non-REM sleep. The last stage is REM sleep, for rapid eye movements. REM is also known as paradoxical sleep, since the nature of the wave, the beta waves, which is the present, when we are awake. REM sleep is the most important part of sleep, as that is when the brain is not the repayment. A body will be paralyzed in REM sleep, dreams occur, especially at this stage, and if the body is not paralyzed, there is nothing to stop people from their dreams. Therefore, even if you have a nightmare, you will not move around in real life, in contrast to what television shows presented.
