For many older adults, the night follows an unexpected script. Just when sleep should be deepest, their eyes open—often at the exact same hour, around 3 a.m. The room is quiet, the world is still, yet the mind is suddenly alert. This experience can feel confusing or concerning, especially when it happens repeatedly. But for millions of people over 60, waking at this hour is not unusual. In fact, it may reflect natural changes quietly reshaping sleep patterns with age.
