The term Sleep Environment reflects all the physical surroundings that influence how comfortable and restful sleep is. This includes things like room temperature, lighting, noise levels, the quality of the mattress and pillows, bedding, odors or air quality, and how easy it is to move or get in and out of bed. In older adults, tuning these elements can reduce awakenings and improve sleep continuity, making it easier to fall asleep and stay asleep.

Physiological factors, by contrast, are internal bodily processes that affect sleep—pain, medical conditions, medications, or sleep disorders. The other options mentioned describe urinary issues, not the bedroom setting, so they don’t capture the impact of the physical surroundings on sleep comfort.
