If we place all the questions we receive side by side, one topic always stands out:

Sleep.

Difficulty falling asleep.
Waking up during the night.
Or sleeping — but not truly feeling rested.

Poor sleep is rarely a matter of willpower.
It is usually a biological signal that your system has been “on” for too long.

In this article, we will guide you step by step through the key layers of sleep: light, hormones, nutrition, stimulation, the nervous system, and energetic balance.

1. We Stay Switched On Too Long

The body operates on a natural rhythm of light and darkness.

Daytime: active.
Evening: slowing down and restoring.

This rhythm is regulated by hormones.

Cortisol and Melatonin

In the morning, cortisol is high.
This hormone helps you wake up, focus, and mobilize energy.

Toward the evening, cortisol should drop.
At that point, melatonin rises — the hormone that prepares you for sleep.

This system responds strongly to light:

• Daylight → active

• Dusk & darkness → relax

And this is exactly where things often go wrong.

2. Artificial Light Confuses the Brain

We spend our days — and evenings — under LED lighting, screens, and phones.

This light contains a high amount of blue light.
And blue light tells your brain: it’s daytime.

The result:

• cortisol remains elevated

• melatonin is suppressed

• the nervous system stays active

You may feel tired —
but your system is still switched on.

Darkness Needs to Be Truly Dark

Even small light sources (standby lights, streetlights, digital clocks) can affect:

• melatonin production

• depth of sleep

• nervous system recovery

Your brain registers light — even when you barely notice it consciously.

3. GABA: The Chemical “Off Switch” of the Brain

You can feel physically exhausted.
But without sufficient GABA, your brain does not truly switch off.

GABA (gamma-aminobutyric acid) is the main inhibitory neurotransmitter in the brain.

Think of it this way:

• glutamate = gas pedal

• GABA = brake

GABA:

• reduces brain activity

• calms the stress system

• decreases rumination

• relaxes muscles

• deepens sleep

Why Many People Are Depleted

Chronic stress, constant stimulation, and lack of true recovery exhaust this system.

The body may also lack the building blocks required to produce GABA effectively.

One important building block is glycine.

Glycine supports relaxation and assists in GABA production and function.

You can find glycine mainly in:

• meat

• eggs

• kefir

• bone broth

Sleep is not a mental trick.
It is a chemical and neurological process.

4. Wi-Fi, Phones, and Invisible Load

Your body continuously operates through electrical signals.

Nerve conduction.
Brain activity.
Heart rhythm.

It is therefore not surprising that artificial electromagnetic fields may influence how calm or alert your system remains.

In people with sleep challenges, we often see:

• difficulty falling asleep

• lighter, more superficial sleep

• frequent waking

• unexplained physical restlessness

Not everyone is equally sensitive.
But in an already overloaded system, this can be the tipping point.

Practical Ways to Reduce Input

• Do not keep your phone next to your bed

• Use airplane mode at night

• Turn off Wi-Fi during sleep

• Consider using a timer for your router

This is not about fear of technology.
It is about reducing noise.

Less input = more recovery.

5. Sleep Is a System of Signals

Sleep is not a single hack.

It is a coordinated biological system.

Restful sleep occurs when:

• light signals that it is night

• cortisol decreases

• melatonin increases

• GABA slows the brain

• glycine helps the body release tension

• stimulation decreases

When these signals align, sleep arises naturally.

6. Energetic Regulation and the Nervous System

Beyond chemistry and hormones, the body also works with fields.

Every cell has an electrical potential.
The heart and brain generate measurable electromagnetic fields.

Chronic stress does not only alter hormones —
it also affects the energetic landscape of the body.

The system can remain in a heightened activation state.

GABA Plasma GaNS

From this understanding, we developed GABA Plasma GaNS.

Not to force anything.
But to offer a field of calm and coherence in which the body can more easily shift.

It functions as a supportive layer.

Not a quick fix.
But an environment in which sleep can re-emerge.

7. A Practical Evening Plan

Here is a calm sequence to help your body understand: it is time to wind down.

1. Limit blue light after sunset

2. Use warm or red lighting

3. Include glycine-rich foods

4. Get natural daylight daily

5. Reduce stimulation at night

6. Optionally support with a calming field

Start small.
Choose one or two steps.
Build gradually.

Consistency makes the difference.

8. My Personal Sleep Routine

For me, one change made a significant difference:
drinking bone broth before bed.

The liver requires fuel at night.
If it runs low — particularly on carbohydrates — cortisol may rise and wake you.

Since incorporating bone broth, I experience deeper sleep and more REM sleep.

Additionally:

• I go to bed between 9:30 and 10:00 PM

• I use blue-light-blocking glasses in the evening

• I switch to red light before bed

• My phone goes on airplane mode

• Wi-Fi turns off at night

• GABA Plasma GaNS is placed beside my bed

Not one trick.
But optimizing everything.

In Closing

Sleep is not a problem to solve.

It is a state that arises when your body feels safe, calm, and supported.

When the signals align, sleep follows naturally.
