Most of us have a nighttime routine. Maybe it is the news before bed. Maybe it is a little scrolling on the phone or a late-night movie. It feels harmless enough.
But according to The Healthy, what you do in those evening hours may have a real effect on how fast your brain ages.
The issue is blue light — the kind that pours out of phones, tablets, televisions, and computer screens. At night, that light can interfere with the signals your brain needs to wind down properly.
When your brain does not get the rest it needs night after night, the effects can add up over time. And for older adults, protecting sleep is one of the most important things we can do for long-term brain health.
The simple takeaway? Cutting back on screens in the hours before bed is one of the easiest changes you can make. It does not require a prescription or a gym membership.
Just a quieter evening. A book instead of a scroll. A little darkness before the lights go out for good.

Your brain does its best work while you sleep. Give it the chance to do exactly that.
