Being dumped by a partner can cause indescribable heartache, and now at least one man has the data to prove how a breakup can actually affect the heart. The Fitbit of Koby Soto, the cofounder of Tel Aviv property management startup Guesty, recorded the exact moment he broke up with by his boyfriend of a few months on 16 January.

Soto told Mashable that his fitness tracker recorded his erratic heart rate when his weekend turned sour. The Tel Aviv University student was meant to meet his boyfriend when he was unceremoniously dumped over the phone.

When he checked his Fitbit, which he initially bought to track his workouts, he was surprised to see what else it had captured. "The first time I saw it I was shocked, and thought it was a bit funny," he said. "I didn't expect to be tracked."

He told BuzzFeed News: "I feel like it's nice to have a log of your confirmation of what you felt. You can tell people you have heartbreak and you feel bad. People become less cynical once you show them the numbers or once you show the data or graphs. Everyone understands heartbreak, right? Everyone's felt it. When you have this, it's interesting—you have something to show."

According to Mashable, Soto said this was the first time his wearable gadget captured any of his romantic emotional trauma. "I've been in a few relationships a lot longer than this and the breakups were much more intense, but I wasn't wearing a Fitbit," he said. Soto later screenshot his heart rate results and posted it on Twitter. It unsurprisingly went viral.

What's more, the results taught Soto that breakups offer cardio benefits and burn fat. He told Mashable that his long-lasting elevated heart rate was probably due to his habit of revisiting the incident in his mind. "I'm quite an emotional type of guy so when I'm in a breakup, I'm in a constant bad mood and constant stress."

Wearables such as the Fitbit can now not only prove heartbreak but can help warn of potential life risks. BuzzFeed News reported a Massachusetts teenager visited the doctors after seeing a series of unusually high heart rate readings off his Apple Watch. There he learned that they were signs of a potentially fatal muscle injury.
