Why watch the sunset every day?
Because it's a short, free, repeatable dose of awe, and awe seems to add up. In a 2020 study, older adults who took weekly 15-minute walks while looking for awe reported more positive emotion and less daily distress over eight weeks than walkers who didn't. A sunset is the easiest awe there is to schedule.
That study, led by Virginia Sturm at UCSF and published in the journal Emotion in September 2020, followed 52 healthy older adults. The awe group also took selfies on each walk, and over time they placed themselves smaller in the frame and smiled more, according to the UCSF release on EurekAlert. The control walkers walked more often but showed no such change. It's one small study, so we hold it lightly. But it fits what most people already suspect after a good evening sky.
Fifteen minutes, looking at something bigger than you, most nights of the week.
What a week of sunsets looked like for us
The first night is the hardest, because it's an interruption. Dinner is half made, someone needs a bath. By night three it becomes the interruption you look forward to: you know when the Sun goes, because Tonight told you at lunch, and you know where, because you watched it go behind the same roofline two nights running.
Night four is where it gets interesting. You guess "vivid", it turns out grey, and Asterfold's journal compares your rating with the forecast it saved earlier that day, never a later one. After three check-ins your colour ratings start to adjust to your own sky, in small, capped steps. By night seven you're reading clouds on the way home from work.
The habit isn't the photo. It's turning around at the right time.
Honest limits
Asterfold's sunset times assume a flat horizon; hills, buildings and trees are not modelled, so your real sunset may come a few minutes early. Its ratings are a rule-of-thumb estimate, not a guarantee, and cloud forecasts from MET Norway can be wrong. And the awe study above was small, in older adults, and didn't test sunsets or an app. A design decision we're glad of: the journal has no streaks, so a missed night costs nothing.
