How to Improve Your Memory
1. Convince yourself that you do have a good memory that will improve. Too many people get stuck here and convince themselves that their memory is bad, that they are just not good with names, that numbers just slip out of their minds for some reason. Erase those thoughts and vow to improve your memory. Commit yourself to the task and bask in your achievements -- it's hard to keep motivated if you beat yourself down every time you make a little bit of progress.
2. Exercise your brain. Regularly “exercising" the brain keeps it growing and spurs the development of new nerve connections that can help improve memory. By developing new mental skills—especially complex ones such as learning a new language or learning to play a new musical instrument—and challenging your brain with puzzles and games you can keep your brain active and improve its physiological functioning. Try some puzzle exercises everyday such as word cross, sudoku and some other games as easy to put into your mobile phone and practise it maybe once for 30 minutes per day.
3. Exercise daily. Regular aerobic exercise improves circulation and efficiency throughout the body, including in the brain, and can help ward off the memory loss that comes with aging. Exercise also makes you more alert and relaxed, and can thereby improve your memory uptake, allowing you to take better mental “pictures."
4. Reduce stress. Chronic stress, although it does not physically damage the brain, can make remembering much more difficult. After prolonged stress the brain will be damaged. Stressful situations are recognized by the hypothalamus, which in turn signals the pituitary gland. The pituitary gland secreted adrenocorticotropic hormone (ACTH)which influences the adrenal glands to secrete adrenaline and later cortisol(corticosteroids). The corticosteroids can weaken the blood-brain barrier and damage the hippocampus(the memory center). Ironically, the hippocampus controls the secretion of the hormone released by the hypothalamus through a process of negative feedback. After chronic stress it will be damaged and it will not be as efficient in regulating the degenerative corticosteroids and memory will be harmed. Neurogenesis (formation of new neurons) indeed exists in the hippocampus but stress inhibits it. To recapitulate and synthesis, chronic stress will affect your health and your memory, it will damage the brain so the best option is to learn to control stress. Stress will never be eliminated, but it definitely can be controlled. [http://ezinearticles.com/?How-Stress-Effects-Neurotransmitters&id=19510]Even temporary stresses can make it more difficult to effectively focus on concepts and observe things. Try to relax, regularly practice yoga or other stretching exercises, and see a doctor if you have severe chronic stress as soon as possible.
5. Eat well and eat right. There are a lot of herbal supplements on the market that claim to improve memory, but none have yet been shown to be effective in clinical tests (although small studies have shown some promising results for ginkgo biloba and phosphatidylserine). A healthy diet, however, contributes to a healthy brain, and foods containing antioxidants—broccoli, blueberries, spinach, and berries, for example—and Omega-3 fatty acids appear to promote healthy brain functioning. Feed your brain with such supplements as Thiamine, Vitamin E, Niacin and Vitamin B-6. Grazing, eating 5 or 6 small meals throughout the day instead of 3 large meals, also seems to improve mental functioning (including memory) by limiting dips in blood sugar, which may negatively affect the brain.
6. Take better pictures. Often we forget things not because our memory is bad, but rather because our observational skills need work. One common situation where this occurs (and which almost everyone can relate to) is meeting new people. Often we don’t really learn people’s names at first because we aren’t really concentrating on remembering them. You’ll find that if you make a conscious effort to remember such things, you’ll do much better. One way to train yourself to be more observant is to look at an unfamiliar photograph for a few seconds and then turn the photograph over and describe or write down as many details as you can about the photograph. Try closing your eyes and picturing the photo in your mind. Use a new photograph each time you try this exercise, and with regular practice you will find you’re able to remember more details with even shorter glimpses of the photos.
7. Give yourself time to form a memory. Memories are very fragile in the short-term, and distractions can make you quickly forget something as simple as a phone number. The key to avoid losing memories before you can even form them is to be able to focus on the thing to be remembered for a while without thinking about other things, so when you’re trying to remember something, avoid distractions and complicated tasks for a few minutes.
8. Create vivid, memorable images. You remember information more easily if you can visualize it. If you want to associate a child with a book, try not to visualize the child reading the book – that's too simple and forgettable. Instead, come up with something more jarring, something that sticks, like the book chasing the child, or the child eating the book. It's your mind – make the images as shocking and emotional as possible to keep the associations strong.
9. Repeat things you need to learn. The more times you hear, see, or think about something, the more surely you’ll remember it, right? It’s a no-brainer. When you want to remember something, be it your new coworker’s name or your best friend's birthday, repeat it, either out loud or silently. Try writing it down; think about it.
10. Group things you need to remember. Random lists of things (a shopping list, for example) can be especially difficult to remember. To make it easier, try categorizing the individual things from the list. If you can remember that, among other things, you wanted to buy four different kinds of vegetables, you’ll find it easier to remember all four.
11. Organize your life. Keep items that you frequently need, such as keys and eyeglasses, in the same place every time. Use an electronic organizer or daily planner to keep track of appointments, due dates for bills, and other tasks. Keep phone numbers and addresses in an address book or enter them into your computer or cell phone. Improved organization can help free up your powers of concentration so that you can remember less routine things. Even if being organized doesn’t improve your memory, you’ll receive a lot of the same benefits (i.e. you won’t have to search for your keys anymore).
12. Try meditation. Research now suggests that people who regularly practice "mindfulness" meditation are able to focus better and may have better memories. Mindfulness (also known as awareness or insight meditation) is the type commonly practiced in Western countries and is easy to learn. Studies at Massachusetts General Hospital show that regular meditation thickens the cerebral cortex in the brain by increasing the blood flow to that region. Some researchers believe this can enhance attention span, focus, and memory.
13. Sleep well. The amount of sleep we get affects the brain's ability to recall recently learned information. Getting a good night's sleep – a minimum of seven hours a night – may improve your short-term memory and long-term relational memory, according to recent studies conducted at the Harvard Medical School.
14. Build your memorization arsenal. Learn pegs, memory palaces, and the Dominic System. These techniques form the foundation for mnemonic techniques, and will visibly improve your memory.
15. Venture out and learn from your mistakes. Go ahead and take a stab at memorizing the first one hundred digits of pi, or, if you've done that already, the first one thousand. Memorize the monarchs of England through your memory palaces, or your grocery list through visualization. Through diligent effort you will eventually master the art of memorization.
2. Exercise your brain. Regularly “exercising" the brain keeps it growing and spurs the development of new nerve connections that can help improve memory.

How to improve your memory - Trying by Not Trying
All of us apply this method knowingly or unknowingly. Sometimes when you try to recall you may not be able to recall it at that time even if you are sure that you know it very well. You experience a blocking that prevents you from recalling it. Normally you tend to try again and again but in vain. To handle this situation you just keep away from trying to recollect it and do something else; to your pleasant surprise that information automatically pops up into your mind after some time. This is because even if you stopped trying, the mind is searching for that information and brings it to awareness when it is found. Sometimes the information was blocked when you wanted, and mind brings it forward when the blocking is removed. This is where stress plays its role in hindering recall.
If you are very anxious by nature or very stressful in nature, you may encounter this type of blockage very often. In such case, it is highly recommended that you practise some kind of relaxation technique and thus keep your anxiety and stress away. This is very important because this behavior can bring many undesirable psychological and physiological conditions. You may even consult a Clinical Psychologist in extreme cases.

How to improve your memory - bed time recital
In this technique, you do your recital or rote learning just before going to bed. The mind in the process of sleeping would then arrange the information in a systematic and effective way when you are sleeping. Psychologists have also found that if you sleep after thinking about your problems there is a better chance that you arrive at a solution the next day.
Steps for Memory Improvement
1. Be in a relaxed mood
2. Write down the things that you are supposed to remember in a piece of paper.
3. Read it aloud (if possible) once or twice and recite it two to three times.
4. Now go to sleep without worrying or thinking about anything.
You will surely retain the item longer and find it more easy to recall it when in need.

How to improve your memory - bridging
Bridging
In this method, a bridge is built in between the items given to be memorized. This technique is best suited for learning material involving word pairs or material that can be reduced to word pairs. An example often cited by memory experts is the learning of the capital of Poland. The capital of Poland is Warsaw. World War II started with Germany's attack on Poland. Thus it may be arranged as Poland SAW War first.
Here, the word pair to be connected together is Poland and Warsaw. The additional information of the World War II is used as a bridge or mediator in bringing these two words together.
Again, like other techniques, the mediation technique calls for the learner's active participation in the learning process. This is because one is to bring in the mediator or the bridge from relevant items one has learned.

How to improve your memory - rhyming
Rhyming
This is also one of the popular and oldest methods in memorization. This technique makes use of the fact that we have a natural tendency to remember rhymes and rhythms. The following is a very popular example of application of this technique which almost all school students are familiar with.
"Thirty days haveth September
April, June and November
All the rest have thirty-one
February has twenty-eight alone
Except in leap year, then the time
When Febs days are twenty-nine."
If possible create rhymes like this and it will not only aid in improving your memory but in improving your creativity as well.

How to improve your memory - chunking
Chunking
Perhaps Chunking is the oldest method used in memorization. In this method, the items to be memorized are divided into small and easily memorizable chunks or groups. This method works best when the order of the items is not important.
This method is found to be particularly well suited for memorizing multi-digit numbers (eg., ID nos., telephone nos., etc.) and for committing complicated spellings to memory.
Example:
1. The number 472627607 may be memorized easily if it is grouped as 472, 627,607 or as 47, 26, 27,607.
These chunks may then be learned by rote. Learning and retention are much facilitated if you further explore the nos. by finding some relationship among these different chunks. Finding the digital root will also be helpful. The more explorations or relations you do, the better.
2. Words like mathematics may be divided into mat +he +mat +ics, Together may be divided into to + get + her; Important may be divided into im + port + ant. This technique will make us learn much faster.
3. The list Apple, cucumber, paper, ink, cabbage, banana, grapes, beans, stapler, orange can be better learned by rearranging and applying chunking as :-
Apple, banana, grapes, orange, cucumber, cabbage, beans, paper, ink, stapler
-- 4 fruits, 3 vegitables and 3 stationary items.
If possible, organize the material as meaningfully as you can and think out relationships among each group. This not only improves learnability and retention but also aids in faster and effortless recollection.
Psychologists doing research on Human Memory have found that the capacity of Short Term Memory (STM) for humans is 7± 2 that is from the range 5 to 9 items. So you should take care to keep the chunks you create within this limit.
