Yes but not for the wearer to take measurements of their body temperature for example to see if they might have a fever. It only takes readings at night while the wearer is asleep, and only provides data in the form of trends against your individual baseline. So it can be useful to see if you were generally hotter last night than normal, which could be useful when sick, but you can't open a thermometer app and check your actual temperature which would have more utility.
