I don’t think our Bay Area health IT reporter Dan Verel wears a Jawbone UP. If he did, he would have been in the minority of the Napa/Sonoma/Vallejo/Berkley users who didn’t wake up during the Sunday morning earthquake in Northern California. When I texted him yesterday to make sure he was OK, he replied, “Yup, didn’t feel a thing and slept right through it.”
One of the number crunchers at Jawbone looked at the sleep data from the company’s Bay Area users and found that the quake ruined a good night’s sleep for 74 percent of people within 25 miles of the epicenter.
Napa, Sonoma, Vallejo, and Fairfield were less than 15 miles from the epicenter. Almost all (93 percent) of the UP wearers in these cities suddenly woke up at 3:20 a.m. when the quake struck. Farther from the epicenter, the impact was weaker and more people slept through the shaking. In San Francisco and Oakland, slightly more than half (55 percent) woke up. As we look even farther, the effect becomes progressively weaker — almost no UP wearers in Modesto and Santa Cruz (and others between 75 and 100 miles from the epicenter) were woken up by the earthquake, according to UP data.
Once awake, it took the residents a long time to go back to sleep, especially in the areas that felt the shaking the strongest. In fact, 45 percent of UP wearers less than 15 miles from the epicenter stayed up the rest of the night.
It pays to be a heavy sleeper if you live in the Bay Area, apparently.
