“Sleep is the basic human need and a natural part of life.”

WE SPEND ABOUT A THIRD OF OUR LIVES SLEEPING.

There are Three Pillars For a Healthier Life

“GOOD SLEEP - BALANCED NUTRITION - PHYSICAL ACTIVITIES”

Out of the Three, Quality Sleep is the Most Important.

When we sleep, our bodies take time to:

● Repair muscles

● Grow bones

● Manage hormones

● Regenerate Cells

● Sort memories

THE IMPORTANCE OF SLEEPING WELL

Having a good night's sleep is essential not only to stay awake the next day but also to maintain

good health. Sleeping well improves well-being and quality of life and also increases longevity.

No other activity delivers so many benefits as a good night’s sleep! Nobody can skip or forget to

sleep.

Studies have shown that getting a good night's sleep can positively impact various aspects of

our lives, including productivity, creativity, emotional stability, physical health, well-being,

concentration, and learning; it also helps our brains function optimally.

Research shows that deep sleep enhances our immune system, which helps the body fight

disease, defends against foreign or harmful substances, increases longevity, and rebalances

serotonin levels.

During sleep, our brain performs essential functions, such as regulating muscle repair and

controlling hormone levels. Additionally, it balances breath, blood pressure, and heart rate to

process new information and form memories.

Good sleep also helps to rebalance the body by producing serotonin, which is responsible for

feelings of pleasure and improving mood and disposition. This is due to the restorative effects of

good sleep, which leaves your body feeling rested and brings numerous health and beauty

benefits.

During sleep, the body secretes growth hormones in children, as well as other essential

substances for the immune system. Children who do not sleep well are more likely to

experience learning problems and physical development problems. Although growth hormones

are released in smaller doses during adulthood, primarily during sleep, they prevent muscle

sagging and maintain physical strength.

Deep sleep triggers the body to release growth hormone (GH), along with other essential

substances for the immune system.

THE FIVE STAGES OF SLEEP

SLEEP is divided into five stages based on brainwaves and muscle relaxation, which 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 the first stage we experience when we first fall asleep and accounts

for about 75% of our sleep time. This stage is crucial because it characterizes the cessation of

muscle movement and the slow movement of the eyes behind the eyelid. That is called the

“twilight” stage of sleep; you may still be aware of some things happening around you.

That is a 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 are regulated, 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.

Stages 3 and 4 are the deepest stages of non-rapid eye movement (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 slows even more, and

the sleepers are tough to awaken and may feel disoriented if an alarm or disturbance pulls you

out of it.

It’s believed that tissue repair occurs during these stages of sleep, and that hormones are also

released to aid in growth.

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, 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, accounting for about

25% of sleep time, characterized by intense brain activity and rapid eye movement.

REM sleep is the cycle during which we experience 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, including the arms and legs, are paralyzed; however, the

fingers and toes may twitch. So, the sleepers can’t act out 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, becoming 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.

A lack of deep sleep is responsible for symptoms such as brain fog, difficulty concentrating,

the need for naps, and irritability.
