The human body varies and it may also be 37.5C. Sick people even more. Might still want to use earphones. Ear canals get pretty close to core temp, as they're near the brain. If you're measuring 32C either you are in a cold environment or you might be misaiming (these things aren't that easy to use, or very accurate). In a warmer climate, the delta gets even less. So yeah, it's a bit surprising that wearables aren't rated for body temperature.
