Want A Better Sleep & Better Energy?
Here's the distinction almost no doctor explains, but is absolutely critical for women over 40, their metabolic health, mitochondria, sleep, and sunlight.
THE TWO TYPES OF MELATONIN
- Brain (Sleep) Melatonin
- Mitochondrial (Internal) Melatonin
Most people only know about the first kind…But it’s the second kind that changes everything about inflammation, aging, hormones, and chronic fatigue.
SLEEP MELATONIN (The one you already know)
Where it’s made-
A tiny gland in your brain called the pineal gland.
When it’s made-
At NIGHT , only after your eyes see darkness and your brain senses that the sun has gone down.
What triggers it-
- Sunset light (orange/red wavelengths)
- Darkness
- A healthy circadian rhythm
- Low nighttime blue light (Screens, house lights)
What it does-
This type of melatonin is like your sleep switch.
- Helps you fall asleep
- Helps you stay asleep
- Lowers core body temperature
- Signals the brain that the day is done
- Supports REM and deep sleep cycles
How artificial (blue) light hurts it -
Phones, laptops, TVs, LEDs, and indoor lighting block pineal melatonin production.
This is often why people feel-
- Wired at night
- Tired in the morning
- Poor recovery
- Middle of the night wakeups
But sleep melatonin is only 5% of the total picture.
The other 95% is WHERE the magic happens.
INTERNAL MELATONIN (MITOCHONDRIAL MELATONIN)
(The one almost nobody talks about)
This is the melatonin your cells make internally, especially your mitochondria, the little engines that make ATP (energy).
And here’s the big difference:
This melatonin does NOT depend on darkness.
It is made from sunlight exposure, especially-
- Near-infrared (NIR) light
- Red light
- A portion of UV light
These wavelengths are present in morning sunlight, midday sunlight, and late afternoon sunlight.
So, You create most of your melatonin during the day, from sunlight, NOT at night from supplements or darkness.
WHAT MITOCHONDRIAL MELATONIN DOES
This internal melatonin is your body’s master antioxidant and cellular repair signal.
Protects your mitochondria from damage
Reduces inflammation inside cells
Repairs oxidative stress
Helps mitochondria make more ATP (energy)
Prevents DNA damage
Slows aging
Protects against metabolic dysfunction
Shields cells from stress and toxins
This type of melatonin is orders of magnitude more powerful than any supplement.
It is the reason sunlight is so profoundly protective and healing.
WHY SUNLIGHT IS REQUIRED
Your mitochondria only make internal melatonin when they’re exposed to specific wavelengths of sunlight.
Without sunlight?
- Chronic fatigue
- Hormonal imbalances
- Weight loss resistance
- Autoimmune issues
- Mood disorders
- Poor recovery
- Increased disease risk
So supplements are like giving your house a night light.
But mitochondrial melatonin is like rewiring the electrical system so your home runs better all day long.
THE BEAUTIFUL CONNECTION BETWEEN SUNLIGHT & MELATONIN
This is why women who start getting daily sun often report -
- Better sleep
- Less anxiety
- Reduced inflammation
- More stable moods
- Improved metabolism
- Higher energy
- Clearer thinking
- Less reliance on caffeine
- Better fat loss results
Their mitochondria are finally getting the light signals they were designed for.
FitnHealthy Tip -
There are two melatonins.
1. Sleep Melatonin (Brain)
Made at night. Helps you sleep.
2. Internal Melatonin (Mitochondria)
Repairs your entire body.
Fixing sunlight exposure is one of the most powerful anti-fatigue, anti-inflammatory, anti-aging interventions available and it’s free.
