If your anxiety spikes and your HRV drops when you overdo coffee (especially late in the day!!), you’re not broken.
It’s just your system reacting to overstimulation, ongoingly (and it could be impacting your sleep, even if you don’t realize it!)!
Too much caffeine, especially later in the day, can raise heart rate, fragment sleep, and lower HRV. As someone who studies sleep for a living, I pay close attention to this research.
A massive umbrella review published in 2025 showed HRV is consistently altered when the nervous system is under strain.
That’s why I swapped my second cup of coffee for MUD\WTR (). The Original blend has about 35 milligrams of caffeine from chai compared to the 90 to 100 you get in coffee. I still feel focused, but my sleep and HRV trends thank me.
Try the swap for three weeks and notice the difference yourself.
Comment ‘HRV’ and I’ll send you the link to their starter kit with a free frother.
