How to wake up sleepless?

HowCanIFallAsleep.com try to help fight the so called "sleep inertia."

Sleep inertia is a physiological state characterized by a decrease in motor skills and a subjective feeling drowsy immediately after a sudden awakening (alarm clock). The impaired alertness may interfere with the ability to perform mental or physical tasks. Sleep inertia can also refer to the tendency of a person wanting to go back to sleep.

Sleep inertia usually occurs after awakening. Upon waking in the morning, the state of subjective alertness and mental performance are significantly altered. Morning sleep inertia takes two to four hours to disappear completely, although there are subjects that can function properly before that time.

The sleep cycle

Sleep at night is organized in 4 or 5 cycles falling over about 8 hours. Each cycle lasting 90 to 120 minutes turn comprises 5 different stages.

Etapas de un ciclo del sueño

Each cycle passes through five stages: 1, 2, 3, 4, and REM (rapid eye movement). These stages progress cyclically from 1 to REM then begin again with stage 1. The first sleep cycles each night have relatively short REM dreams and long periods of deep sleep but later in the night, REM periods lengthen and time deep sleep is shortened.

Stage 1 is the lightest of the sleep and wake up is easier. During this stage, many people experience sudden muscle contractions preceded by a sensation of falling.

Stage 2, eye movement stops and brain waves become slower with only an occasional burst of rapid brain waves.

In stage 3, there are extremely slow brain waves called delta waves are interspersed with smaller, faster waves.

In stage 4, the brain produces delta waves almost exclusively. Stages 3 and 4 are referred to as deep sleep, and it is more difficult to wake someone from them. When we are in deep sleep, no eye movement or muscle activity.

The REM (Rapid Eye Movement) stage is when breathing becomes more rapid, shallow and irregular, eyes and quickly stir limb muscles are temporarily paralyzed. The brain waves during this stage are similar to those experienced by people to be awake, the heart rate increases, blood pressure rises, men experience erections and the body loses some of the ability to regulate its temperature. Is the time when most dreams occur, if a person is awakened during REM sleep, you may remember dreams. Most individuals experience three to five intervals of REM sleep each night.
