Watch: Vet uses Apple Watch on lion's tongue to measure heart rate in surprising discovery
Viral Video: In a groundbreaking move for wildlife health monitoring, veterinarians in Australia are now using Apple Watches to check the health of wild animals. Dr. Chloe Buiting, known online as "@Jungle_doctor," recently shared a video on Instagram that highlights this innovative approach. The video shows a sedated lion with an Apple Watch placed on its tongue, demonstrating the remarkable potential of technology in animal conservation.
Dr. Buiting explained in the caption: "@apple Watch can measure a lion's heart rate if you strap it to the tongue... a true 'technology meets conservation' story." This off-label use of the Apple Watch underscores the innovative ways technology can aid in wildlife conservation.
The technique was inspired by Dr. Fabiola Quesada, a renowned wildlife veterinarian, who first used an Apple Watch to measure an elephant's heart rate by attaching it to the animal's ear. This method has proven to be a safe and effective solution for monitoring vital signs in large, wild animals.
Veterinarians secure the Apple Watch on a sedated lion's tongue to monitor its heart rate in real-time during medical procedures. This innovation ensures efficient tracking of the animal's vital signs, ultimately contributing to improved animal care.

The Apple Watch uses photoplethysmography technology to track heart rates. This method relies on the fact that blood absorbs green light and reflects red light. The watch uses green LED lights paired with light-sensitive photodiodes to detect changes in blood flow. By flashing the LEDs hundreds of times per second, the watch measures how much green light is absorbed, allowing it to calculate the heart rate.
Apple states that the sensor can handle a wide range of 30-210 beats per minute. To ensure accuracy, it adjusts for weak signals by increasing the LED brightness and sampling rate. Additionally, the sensor can use infrared light for background heart rate checks and notifications.
For activities like workouts and mindfulness sessions, the watch switches to green LEDs for more precise heart rate monitoring. This allows it to calculate walking average heart rates and assess Heart Rate Variability (HRV).
