Jet Lag Isn’t Just Being Tired
Sorry I’m late, but truthfully, my body is still in another time zone.
I started writing to you this week from Los Angeles after flying in from New Orleans. Then I got caught up spending time with my family, flew back to Baltimore, landed at 5:00 a.m., and went straight to my internship because I genuinely love the work I’m doing right now.
So yes… ya girl is “Jet Lagged”.
By Friday, I crashed and realized I needed to write a letter for everybody: Diabaddies, our allies, and anyone who’s ever traveled and wondered why their body felt completely off afterward.
We need to talk about what flying, changing time zones, interrupted sleep, irregular meals, and sprinting through airports actually does to the body.
All of these things can affect glucose levels, and that doesn’t just affect people living with diabetes.
Nobody’s safe.
The Truth
That “Biological Clock” is REAL …
I can’t believe I have to face my fate and tell y’all that I used to be one of those silly people who thought the body couldn’t tell what time it was. Since then, I’ve learned not to speak too confidently before doing the research.
Your brain has a master clock called the suprachiasmatic nucleus, or (SCN), that uses light and darkness to help regulate when you sleep, wake up, feel hungry, release hormones, and perform at your best.
When you cross time zones, the clock on your phone changes immediately, but your internal clock is still following the schedule you just left. It then has to slowly reset itself using cues like sunlight, sleep, meals, and activity, which is why I can be physically standing in Baltimore while my body is still operating like it’s in Los Angeles.
That temporary mismatch is jet lag, and it affects my sleep, focus, digestion, mood, and physical performance until my body catches up.
So yes… My body absolutely knows what time it is. It just may not agree with the time zone I’m in yet.
