The Venu 4's Health Status feature makes it easy to understand changes in heart rate, heart rate variability (HRV), respiration rate, and other personal metrics compared to your usual range. For example, it displays rising/falling trends outside the user's normal range at a glance, allowing early detection of abnormal conditions.
In addition, with the Lifestyle Logging feature, users can record coffee, alcohol, exercise, and stress events as user input or presets, and visualize how these behaviors affect sleep, stress, and HRV. The new sleep alignment metric assesses how well the user's actual sleep pattern matches their biological rhythm (circadian rhythm) and provides personalized sleep improvement guidance.
In terms of exercise, the Garmin Fitness Coach suggests personalized exercise programs for over 25 types of exercise, taking into account the user's health, fitness, and recovery status. Supporting all of these features, the smartwatch achieves a battery life of up to 12 days in smartwatch mode, reducing the chance that users will miss data due to charging the watch every night.
