Embodiments of this application relate to the field of communications technologies, and provide a light adjustment method and a terminal to resolve a problem that an existing light therapy device cannot flexibly adjust light based on a light requirement of a user and cannot more intelligently adjust a circadian rhythm of the user. The method includes: determining, by a terminal, an awake time period and a sleep time period of a user, and determining light parameter thresholds in the awake time period and the sleep time period; and then obtaining, by the terminal, a light parameter in a current time period, and adjusting, based on the light parameter in the current time period, a light parameter of light emitted by a light source device. This method is used in a process of adjusting the light emitted by the light source device. |
