When we sleep, our bodies take time to:
- Repair muscles
- Grow bones
- Manage hormones
- Sort memories
THE IMPORTANCE OF SLEEPING WELL
WE SPEND ABOUT A THIRD OF OUR LIVES SLEEPING.
Good sleep is necessary for physical and mental health, as well as for well-being throughout our life.
Having a good night's sleep is essential not just to stay awake the next day but also to stay healthy. Sleeping well improves the quality of life and increases longevity.
Sleep is responsible for a healthy and happy life, including health support and brain function.
No other activity delivers so many benefits with so little effort than a good night’s sleep! Nobody can skip or forget to sleep.
Our physical and mental performance is directly linked to sleep; however, spending your night with a "restful sleep" makes the difference.
People who get restful sleep have more attention and are more willing and ready for normal activities of daily living. Sleep helps us thrive by contributing to a healthy immune system and can also balance our appetites by helping to regulate levels of the hormones ghrelin and leptin.
Research shows that deep sleep improves our immune system, helps the body fight disease and maintain balance with its surroundings, defends our body against foreign or harmful substances, increases longevity, and rebalances serotonin.
Studies show that getting a good night's sleep can improve productivity, creativity, emotional balance, physical vitality, concentration, and learning and help our brain work properly to maintain our physical health and prepare us for the future. Also, good sleep aids in growth and development.
During sleep, the brain regulates essential functions in muscle repair and control of various hormone levels. Breath, blood pressure, and heart rate are balanced to where the new information is processed and memories are formed.
Sleep also rebalances the body by producing serotonin, the hormone responsible for feelings of pleasure, improving mood and disposition. It comes from the effect of good sleep called "reparative," which leaves your body rested, bringing health and beauty benefits.
The growth hormone is secreted in children and some essential substances to the immune system during sleep. Children who sleep poorly are more likely to have problems in their physical development.
Although growth hormones continue to be released even in adulthood, in smaller doses, it still happens during sleep. In adults, it prevents sagging muscles and ensures physical force.
Poor sleep children are more likely to have learning and physical development problems.
Deep sleep triggers the body to release growth hormone (GH), which is secreted during sleep along with other essential substances to the immune system.
THE FIVE STAGES OF SLEEP
SLEEP is divided into five stages following brainwaves and muscle relaxation, during which the body will need to go through some steps that will prepare the body for recovery.
Every stage that passes through “non-REM sleep” gets smaller as the “REM” sleep gets longer.
Stage 1: “Non-REM sleep” is when we first fall asleep and takes up about 75% of our sleep time. This stage is crucial because it is characterized by the cessation of muscle movement and the slow movement of the eyes behind the eyelid; called the “twilight” stage of sleep, you may still be aware of some things happening around you.
Stage one is the light stage of sleep, and noises or other disturbances can usually wake you.
During this stage:
- Eye movements are typically slow and rolling.
- Heartbeat and breathing slow down.
- Muscles begin to relax.
- You produce low amplitude mixed frequency waves in the theta range (4 to 7 Hz).
Stage 2: “The Non-REM Sleep” is the stage where you are fully asleep and unaware of your surroundings.
During stage 2, the heart rate and breathing regulate, the body temperature decreases, and the eye movements either slow or stop altogether.
During this stage:
- Heartbeat and breathing slow down further
- No eye movements
- Body temperature drops
- Sleep spindles and K-complexes are two distinct brain wave features that appear for the first time.
Stage 3 and 4: is the deepest stage of Non-REM sleep. These stages are called Slow Wave Sleep (SWS) or Delta sleep. The Electroencephalogram (EEG) shows a slower frequency with high amplitude signals.
Stages 3 and 4 are a deep sleep cycle where muscles relax, and breathing becomes even slower; in these stages, sleepers are tough to wake up and may feel disoriented if an alarm or disturbance pulls them out of their sleep.
Tissue repair occurs during these sleep stages, and hormones are also released.
During this stage:
- Arousal from sleep is difficult
- Heartbeat and breathing are at their slowest rate
- No eye movements
- The body is fully relaxed
- Delta brain waves are present
- Tissue repair and growth, and cell regeneration occur
- The immune system is strengthening
- Blood pressure drops
- Blood supply to muscles increases
- Energy is restored
After 70 minutes of “Non-REM sleep,” we enter the first period of REM.
Stage 5: “The REM SLEEP” comes after the Non-REM sleep (NREM) phase, which is about 25% of sleep time and is characterized by intense brain activity and rapid eye movement.
REM sleep is the cycle where we have dreams; the eyes move rapidly behind the lids, and breathing becomes shallow and rapid. The blood pressure and heart rate also increase during REM sleep, and the muscles, arms, and legs are paralyzed, but the fingers and toes may twitch. So, the sleepers can’t act out of their dreams.
At that moment, the body becomes immobile and relaxed; the brain repairs the damaged tissue and generally cleans up memory, fixing important information captured during the day and discarding useless data.
REM SLEEP occurs approximately 90 minutes after falling asleep and recurs about every 90 minutes, getting longer later in the night.
When the REM stage ends, we return to the Non-REM Sleep (NREM) phase and repeat this cycle about five times a night.
Lack of deep sleep is responsible for symptoms like; brain fog, inability to concentrate, the need for naps, and irritability.
