Stop. If you’re struggling to fall asleep, one of these three things is probably the reason.
First—light exposure at night.
Even small amounts of blue light from your phone suppress melatonin, the hormone that tells your body it’s time to sleep.
If you’re scrolling in bed, your brain thinks it’s still daytime.
Second—late caffeine.
Caffeine has a half-life of 6 to 8 hours.
That afternoon coffee at 3 PM?
Half of it is still active in your system at 10 PM.
Third—overheating.
Your body needs to drop its core temperature to fall asleep.
A warm room or heavy blankets can quietly disrupt this process.
Here’s the fix:
Dim your lights 1 hour before bed,
cut caffeine after 2 PM,
and keep your room slightly cool.
Try this tonight—and notice the difference."
