How to increase nighttime HRV:

🏃 Exercise in the morning
🥘 Don't eat <3 hours before bedtime
🥃 No alcohol
🧠 Get a vagus nerve stimulation device (e.g. Nurosym)
🩸 Reduce inflammation (rapamycin is king, omega-3 also ok)
💊 Supplements: Ashwagandha, Magnesium L-Threonate, Probiotics

No alcohol is probably the most obvious one. 
HRV is totally crashed after a night of drinking.
