““The Japanese see the seasons as signposts, visible reminders of our own natural rhytms. In modern life, these often get disrupted, as we extend our days with strong artificial light, interrupt our sensitive biorhytms with blue lights from our electronic devices and push ourselves to be highly productive just because it's another weekday. We push on, regardless of whether our body is trying to tell us it's time to hibernate, or get outside for some summer sunshine - and then we wonder why we get sick.””
