What happens during light sleep stage.

Neuroscientists strongly suspect that the brain transfers memories from short term storage to long term storage during stage 2 making this form of sleep essential for learning. The second stage moves into a slightly deeper sleep and stages three and four represent our deepest sleep. During light sleep your heart and breathing rates are lower than they are when you are awake. There are bursts of electrical activity in your brain which boost your brain s communication system and your ability to learn and remember.

The second stage of light sleep consists of over half of our time asleep each night. It s when your body processes memories and emotions and your metabolism regulates itself. The name slow wave sleep refers to what is happening to our brain at this stage. Heartbeat and breathing slow down further.

Stage 1 is the beginning of the sleep cycle and is a relatively light stage of sleep. Stage 1 can be considered a transition period between wakefulness and sleep. Light sleep is very important because it takes up more than half of the night says grandner. Most light sleep happens in the second stage.

This next stage of non rem sleep is a period of light sleep before you enter deep sleep and it lasts for roughly 25 minutes. The second stage is where sleep spindles occur which are basically bursts of brain activity. It s thought that sws is when the mind processes explicit information recorded during the day. Light sleep may not sound very important but it is a part of our sleep cycle that we need to wake up feeling refreshed from restful sleep.

The first stage is a very light sleep from which it is easy to wake up. The body rests during light sleep and cell repair occurs although perhaps not to the extent that happens in deep sleep. Memory is backed up in light sleep. In stage 1 the brain produces high amplitude theta waves which are very slow brain waves.

Electroencephalograms show that in this stage of our sleep cycle our brain waves have slowed considerably and have become much larger. The first stage of light sleep is a transition phase and only makes up about 3 of our total sleep time. The first stage is the lightest of sleep where it prepares the body to go to lighter sleep in preparation for deep sleep which is the third stage. In the sleep wake cycle we first enter the non rem stage where the stages 1 and 2 is where light sleep happens.
