Garmin is launching the Venu 3 and smaller Venu 3S smartwatches today with a greater focus on sleep-tracking and personalization. In particular, it's adding a proactive sleep coaching feature and nap detection. The latter is noteworthy, considering most modern smartwatches from companies like Apple, Samsung, and Google can track your sleep, but only at night. With the Venu 3 series, you'll be able to rest easy knowing your daytime slumber can also be tracked, if that's your kind of thing.  

The company's new sleep coach considers factors such as a user's daily activity levels, sleep history, and heart rate variability (HRV) – which is a sleep metric new to the Venu series. The coach will provide recommendations on the amount of sleep you’ll need to make it through the next day. The naps that the Venu 3 detects will also go towards replenishing energy levels as tracked by the company’s “Body Battery” tool, which quantifies energy levels on a scale of 1-100 depending on activity expenditure.
