More on sunlight (and possibly Vitamin D) and cortisol:

This insight into how morning light affects cortisol regulation is fascinating—especially for those optimizing their daily rhythms. Alongside sunlight exposure, managing artificial light is equally important. One effective strategy is to activate a full screen black screen using black screen onl during evening hours or screen breaks. This tool delivers a smooth, full-screen charcoal display that helps reduce blue light exposure, supports melatonin release, and minimizes digital eye strain. Whether you're winding down or simply resting your eyes, it’s a no-fuss, plugin-free way to create a calming visual environment aligned with natural hormone cycles and wellness goals.
