What Happens if Younger People Take Melatonin? (And Yes, Skin Color Affects Infrared Absorption)

Let’s cut through the fluff and get real.

You’re here because you want straight-up answers. Should older people take supplements at night? What happens when younger people pop melatonin like candy? And yes, we’re even going there — does skin color affect how the body absorbs infrared (IR) light?

Short answer: Often, yes — but not just any supplements and not just because it's nighttime.

Why nighttime supplementation can be powerful for older adults:

• Sleep repair mode = nutrient absorption mode
  At night, your body shifts into parasympathetic dominance — aka “rest and digest.” This is prime time for tissue repair, hormonal recalibration, and cellular regeneration. For older individuals, whose systems may not bounce back like they used to, this phase is gold for nutrient utilization.

• Melatonin production declines with age
  After 50, melatonin production starts to nosedive. Supplementing small doses (0.3–1 mg) at night can support better sleep quality without the groggy side effects that come with overdosing (which we’ll talk about in a second). Better sleep = better recovery.

• Magnesium, glycine, and B vitamins = deeper rest
  Many older people are deficient in magnesium, and stress over time depletes it further. Taking a magnesium glycinate supplement at night can support muscle relaxation, sleep, and even blood sugar regulation.

• Joint recovery, inflammation, and immunity
  Collagen, turmeric/curcumin, and omega-3s can be especially helpful at night when the inflammatory response is lower and regeneration ramps up.

Here’s the part most people don’t want to talk about: younger people don’t always need melatonin. And misusing it can backfire.

Melatonin isn’t a sleeping pill. It’s a hormone.

If you're under 40, your body should already be producing enough melatonin — assuming you’re not glued to a screen until midnight, blasting your face with blue light. (Yeah, we see you.)

When young people take melatonin regularly:

• It can disrupt natural circadian rhythms, especially if taken too late.

• It might reduce your body’s own production of melatonin over time.

• It can cause grogginess, vivid dreams, and even mood fluctuations.

• Overuse has been loosely linked to hormonal imbalances, since melatonin has downstream effects on the pituitary gland.

When is it actually helpful?

• Jet lag or shift work

• Resetting a messed-up sleep schedule

• Occasional use during times of high stress

If you’re young and struggling to sleep, melatonin is not your first move. Look at your screen exposure, caffeine intake, blood sugar stability, and cortisol levels. Then talk supplements.

Yes — and here’s where we bust the silence wide open.

Let’s get one thing straight: infrared therapy is amazing — for cellular regeneration, pain relief, inflammation reduction, and even mitochondrial health. But how it affects you can vary based on your skin’s melanin content.

Melanin = Light Filter

Melanin is like a natural sunblock. It protects the skin by absorbing and deflecting UV and visible light. But when it comes to infrared light, the story shifts.

• Far infrared (FIR) can penetrate up to 4 cm deep into the skin, regardless of skin tone.

• Near infrared (NIR), especially wavelengths like 850nm, are partially absorbed by melanin — meaning that darker skin may slightly absorb more IR energy superficially, resulting in less energy reaching deeper tissues.

But here's the kicker: that doesn't mean it doesn’t work. It just means:

• Session time may need to be longer for deeper benefits in melanin-rich skin.

• Placement matters — using IR on less pigmented areas (palms, soles, torso) can be more efficient for deep cellular activation.

So if you’re using red light therapy or an IR sauna, know your biology. It’s not about exclusion — it’s about optimization.

You’re not here to live halfway. You’re here because you’re done with second-guessing your health.

Here’s what you walk away with:

• Older people taking supplements at night? Yes, especially for sleep, inflammation, and recovery. But choose wisely. This is not a multivitamin free-for-all.

• Younger people taking melatonin? Use sparingly. Respect your hormones. Fix your sleep hygiene first.

• Skin color and infrared light? Melanin filters light, but it’s not a barrier to healing — it’s a signal to adapt your approach. Bio-individuality wins every time.

This isn’t about following the crowd. It’s about owning your biology, your age, your skin, and your sleep — and making smarter, bolder choices with your wellness strategy.
