Abstract: A method for determining natural illumination duration and an electronic device are provided, to more accurately determine a scenario in which a user is located and effectively determine natural illumination duration, to help the user improve vision. The method is applied to an electronic device having a display screen and includes: determining a current scenario based on a preset reference factor (S901), where the preset reference factor includes any one or more of ultraviolet intensity, illumination intensity, and locating signal strength; and counting current natural illumination duration towards cumulative natural illumination duration if the current scenario is a preset scenario (S902), where the preset scenario includes any one or more of an outdoor scenario, an indoor near-window scenario, and an outdoor blocked scenario.

Abstract: One example blood pressure measurement device includes a body, a wrist strap, an airbag, an air supply and exhaust apparatus, a first sensor, and a second sensor. The airbag has an air cavity, and the airbag is connected to the body. The body includes a cavity, and the air supply and exhaust apparatus is disposed in the cavity. The air supply and exhaust apparatus includes an air intake path and an air exhaust path, and the air supply and exhaust apparatus communicates with the air cavity of the air bag. The first sensor is configured to measure an air pressure value in the air cavity. The second sensor is located on a same side of the wrist strap as the airbag, and is configured to measure a pulse wave signal.
