To maintain optimal, properly synchronized circadian rhythms, the body requires periods of both light and darkness. Light exposure stimulates the circadian system, which regulates physiological rhythms throughout the body’s tissues and organs, such as hormone levels and the sleep-wake cycle. Disruption or desynchronization of the circadian rhythm has been linked with obesity, diabetes, depression and metabolic disorders.

WELL Certification emphasizes the importance of mental health and wellness in the workplace. Providing annual communication about mental health and well-being benefits, resources, and programs ensures that all eligible employees are aware of the support available to them and encourages them to make use of these resources. This aligns with WELL's commitment to fostering environments that support physical and mental health, as regular communication can reduce stigma and barriers to accessing mental health care

Achieving 150 EML [136 M-EDI(D65)] is a strategy to support circadian rhythm in a project with a small amount of glazing. EML stands for Equivalent Melanopic Lux and M-EDI stands for Melanopic Daylight Illuminance. These are metrics that measure the intensity of light that stimulates the melanopsin receptors in the eye, which are responsible for regulating the circadian rhythm. The higher the EML or M-EDI, the more effective the light is for circadian entrainment. Feature L03: Circadian Lighting Design5 requires projects to achieve a minimum EML or M-EDI value for at least 4 hours per day in all regularly occupied spaces. For projects with a small amount of glazing, artificial lighting can be used to supplement the daylight and achieve the required EML or M-EDI value.

• Supporting Evidence: WELL features often require specific design elements or operational protocols to be met. Annotated plans, drawings, or specifications provide clear evidence demonstrating how the project meets these requirements.
• Feature-Specific Requirements: Each feature has its own verification methods in the WELL Building Standard. Annotated documents are particularly important for features with visual or spatial requirements.
• Clarity for Reviewers: Annotations highlight crucial details, making review more efficient for the WELL assessors. They demonstrate that the project team has carefully considered and implemented the specific requirements.
