Either of my daily showers border my bedtime, one before and one after. I shower before sleep so that I can clean my dirtied skin after an active day, and then I do so again once I wake up in order to clean my skin of oils collected during sleep. I've never understood how people can go without washing themselves at least once per day, however. How much more stench must their fellows around them endure? The grime, the sweat, the clamminess of it all, it might as well become their new epidermis.
