Every year I get the same question:
“How do you keep a Christmas tree in your house without wrecking your circadian rhythm?”
So here’s exactly what I do -step-by-step -with my own 9-foot live tree.
1. First: No, I’m not worried about toxins from live Christmas trees.
There’s a lot of fear-based content online about “toxins” from evergreen trees.
For most people, this is not a realistic concern - especially if you:
• keep your tree watered
• use a HEPA purifier (I use my JASPR air purifier)
• don’t have a known pine allergy
I’ve had live trees for years (and with 2 kiddos who have allergies and sensitive systems). Zero issues.
2. The lighting is what determines whether your tree is circadian-friendly.
This is the part almost everyone gets wrong.
I use incandescent mini lights, not LEDs.
Here’s why:
LED Christmas lights = bright blue spikes
When you measure them on a spectrometer, LED strands produce strong blue peaks and higher overall brightness - exactly the kind of light that suppresses melatonin, increases alertness at night, and shifts circadian timing later.
Incandescent mini lights = no blue spike

My spectrometer shows very little blue light, a warm continuous spectrum, and far lower brightness.
This is why incandescents feel calming instead of stimulating.
I use 9 strands of incandescent minis on my 9-foot tree.
3. Lux matters: Measure from where you actually sit.
This is the piece most people overlook.
I don’t measure lux next to the tree.
I measure lux from the couch - the place I’m actually spending my evenings.
Using MyCircadianApp, the reading from my sofa comes out to:
6 lux.

That is well within the range that won’t meaningfully suppress melatonin for most people.
Your goal:
Keep your evening environment the 3 hours leading up to bed under ~10 lux, and ideally under 5–6 lux, depending on your sensitivity (learn more about lux in my free webinar - click here)
That’s why the bulb type matters so much - LED trees tend to push lux & blue light far higher.

4. How to make your tree circadian-friendly:
✔️ Use incandescent mini lights
Avoid LEDs if you want to protect melatonin.
✔️ Use MyCircadianApp to measure lux
Measure from where you sit - couch, dining table, etc.
Not from next to the tree.
(Learn more about WHY lux matters in my free webinar)
✔️ Keep the room otherwise dim
Don’t combine a bright tree with overhead LEDs or bright lamps.
✔️ Turn the tree OFF before bed
I unplug mine every night. Incandescents run warm, so it’s good practice anyway.
5. Safety & care for live trees
Live trees are amazing - but do take care of them:
• Water it daily. A dry tree is flammable.
• Use a humidifier underneath (I run mine on low). It prevents needles from drying out.
• Keep incandescents off when you’re not home or asleep.
• Consider a purifier like the Jaspr (code SARAK for $400 off) nearby if you’re sensitive to smells or allergens.
In short:
A Christmas tree can absolutely be circadian-friendly - it just comes down to lighting, lux, and nighttime routines.
If you follow this protocol, you can keep the holiday magic and keep your melatonin intact.
