Before you can improve your memory the first step is to learn how it works. For memory there is a process your brain goes through where it first acquires or registers incoming information, consolidates and sorts that information and at a later time you have that ability to recall the information that has been acquired and stored. This is a process of the brain and the nervous system working together, and it contains two kinds of information: knowledge and procedures. Below are just a few tips that you can easily employ to help improve your memory.
It's going to sound crazy to say it... but the best way to improve your memory, is by using it regularly. What I mean by this is doing things like trying to remember things you haven't thought of in a long time, or to think differently to your 'everyday thinking'. And example might be to think of the make or model of every car you've ever owned, or to think of every animal that begins with the letter 'P'. This flexing of your memory helps to make it more nimble and agile, just a like a muscle that gets stronger the more you use it.
If you were to learn a new language, your brain would have to absorb a huge amount of new information. New sounds, new concepts and of course, new words. This also will help to stretch your brain, giving it new things to absorb and retain, and thereby helping to improve your overall brain function, including your memory.
New studies also suggest that taking short naps during the day improves memory. At the onset of sleep a period of processing begins which boosts your memory. Stress is a factor in all of our lives but when it becomes an overpowering factor to our health, we need to do something about it. And don't forget, physical exercise will also make your memory better (especially as you get older) as this aides the blood flow to the whole body (including the brain).
These are just a few simple ways that you can improve your memory starting from right now. There are also more advanced methods that you can use to improve your memory. Kenneth Higbee's book 'Your Memory: How It Works And How To Improve It' uses techniques like: Link, Loci, Peg, and Phonetic systems which can be incorporated into your everyday life. He also teaches on aging and memory and the latest information on the use of mnemonics,
