About 3 years ago, I did genetic testing through 23andMe (before they went bankrupt 😅), and then ran the data through Seeking Health’s StrateGene report.
At the time, it was honestly pretty fascinating.
One SNP that stood out for me was:
MTNR1B rs10830963
Mine was listed as:
(+/- CG) “slow”
This gene is involved in melatonin signalling and circadian rhythm regulation.
And honestly?
It explained A LOT 😂
I have always struggled more with:
• delayed sleep
• feeling more awake at night
• getting a “second wind” late evening
• difficulty falling asleep even when tired
And this is why I always laugh a bit when people say:
“just wake up earlier"
or
“just use better sleep hygiene”
Like yes… those things CAN help!
But biology is nuanced 😅
Interestingly, learning about this SNP was one thing that helped me stop feeling guilty about occasionally needing melatonin support.
I actually stopped using melatonin for quite awhile…
…but this past winter? 😵💫
Once February hit, my sleep became absolute chaos and I eventually brought melatonin back in because I genuinely felt like my circadian rhythm needed support before I became an actual lunatic hahaha.
And honestly? It helped.
Now — genetics are NOT destiny.
This SNP does NOT mean:
“You are doomed to terrible sleep forever”
Genes are more like:
• tendencies
• vulnerabilities
• patterns
• probabilities
Environment still matters MASSIVELY:
• light exposure
• stress
• screens
• nervous system state
• meal timing
• sleep consistency
• movement
• seasonality
…all influence how these genes express.
But I DO think understanding our biology can help us work WITH ourselves a bit more compassionately.
Because sometimes there really is a physiological reason why certain things feel harder for some people.
And honestly?
The more I learn about circadian biology, the more I realize:
humans are not designed for LED lights, doom scrolling at midnight, night shifts, caffeine at 5pm, and pretending our brains don’t care 😂
𝗧𝗵𝗲 𝗡𝗲𝗿𝗱𝘆 𝗧𝗮𝗸𝗲𝗮𝘄𝗮𝘆 🧠
Genes don’t create our destiny.
But they absolutely can influence the way we experience the world, stress, sleep, metabolism, and nervous system regulation.
Sometimes learning those patterns helps us stop fighting ourselves so hard.
