The goal of this intervention is to learn if a combination of morning blue light and evening red light therapy can improve sleep quality in adults with subclinical sleep complaints (non-diagnosed difficulty initiating or maintaining sleep). The main questions it aims to answer are: Does combined morning blue light and evening red light therapy reduce sleep onset latency (the time it takes to fall asleep) and improve sleep efficiency? Does this light therapy intervention improve subjective alertness upon awakening? Researchers will compare each participant's objective and subjective sleep data during a 7-day baseline (habitual routine) with their data during a 7-day light therapy intervention to assess whether light therapy improves sleep and daytime alertness.
