What should I do if I'm noticing my memory getting worse?

I've noticed that after a stressful day, information doesn't stick in my head as well, but then I realized - it's mostly about attention, not actual memory. Now I try to move regularly, sleep well, and keep my brain sharp by learning something new - and it really has gotten easier with concentration and recalling information. Doctors usually mention these exact three things: physical activity, proper sleep, and continuous learning (reading, learning languages, diving into new topics). In everyday life it works - don't expect miracles, but there's a noticeable effect if you do it consistently rather than just once in a while.

The main thing is don't panic and don't go buying miracle supplements that promise to restore your memory in a week. Actually, the methods that have been suggested (sleep, exercise, cognitive activities) really do help, but here's the catch: you won't see results right away - you need weeks and months of consistency. A lot of people start, don't notice anything after a week or two, and give up thinking it's not working. Also, you should rule out the obvious causes - maybe your attention has just gotten scattered with age or you're under stress, like others have already pointed out. If your forgetfulness has suddenly gotten much worse or it's really bothering you, you should still see a doctor, because sometimes there's something more serious going on behind it.
