Waking up at 3 a.m. and being unable to fall back asleep is common, especially after age 60. Aging, habits, bodily signals: should we be worried or simply adjust our rhythm?
Waking up in the middle of the night, eyes wide open at 3 a.m., with the feeling that sleep will never return… Sound familiar? Don’t worry: this is a very common phenomenon, especially after age 60. But why does this particular time occur so often? Is it simply related to age… or a sign that an adjustment is needed? Let’s take a closer look, without making a big deal out of it.
A natural decline in melatonin with age.
Our sleep is guided by a key hormone: melatonin. It helps the body understand that it is time for deep sleep.
Over the years, its production naturally decreases. As a result, sleep becomes lighter and more fragmented. Around 2 or 3 a.m., its level can be low enough to trigger a spontaneous awakening.
Add to that a greater sensitivity to light (outdoor streetlight, indicator light on electronic device, screen left on…) and the brain can interpret these signals as the approach of morning.
Simple tip: completely darkening the room (closed shutters, blackout curtains) and avoiding screens for at least an hour before bedtime can really improve the quality of sleep.
