Unlock better HRV by prioritizing sleep in dark, cool rooms. Limit screens before bed. Master controlled breathing (4s in, 6s out) to activate your nervous system. Reduce alcohol, especially before shifts. Train smart: adjust intensity based on your HRV. Stabilize blood sugar by focusing on protein intake. #HRV #HealthTips #SleepHygiene #BreathingExercises #Fitness
