Key Differences
Sunlight refers specifically to the direct light we receive from the sun, known for its intensity and warmth. Whereas daylight encompasses not just sunlight but also the diffused light from the sky during the day, which can include shades of light even when the sun is obscured.
Sunlight is responsible for the vivid colors and sharp shadows we see outdoors, contributing significantly to the visual clarity of objects. On the other hand, daylight, with its combination of direct and indirect light, provides a softer, more uniform light that reduces harsh contrasts and shadows.
The health benefits of sunlight, such as vitamin D synthesis, are well-documented, highlighting its importance in maintaining physical well-being. In contrast, exposure to daylight, even without direct sunlight, is essential for regulating our circadian rhythms and overall mental health.
Sunlight plays a crucial role in the process of photosynthesis, which is vital for plant growth and the production of oxygen. Meanwhile, daylight, regardless of direct sunlight, influences plant and animal behaviors, indicating the broader ecological significance of natural light cycles.
Understanding the distinctions between sunlight and daylight can enhance architectural and lighting design, optimizing spaces for health, productivity, and energy efficiency.

Sunlight
Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon.
Daylight
Daylight is the combination of all direct and indirect sunlight during the daytime. This includes direct sunlight, diffuse sky radiation, and (often) both of these reflected by Earth and terrestrial objects, like landforms and buildings.
