Here are some tips on how improve your memory works, and some reasons why you need them.
Having a good memory simply indicates intelligence, youth, and vibrancy.
People who have good memories succeed more in life whether in school or in jobs.
A good memory can even help in relationships.
Now here are the ways to sharpen your memory, and naturally improve your overall mental health:

1. Exercise your mind.
   Exercising your mind through brain plays, problem solving, and memory games can keep your mind sharp and alert always.
   You can find free mental games such as puzzles, teasers, or riddles online available to you any time.
   
2. Get sufficient sleep.
   Sleep is proven to affect the brain's health and memory functions.
   In fact people will die sooner because of lack of sleep rather than out of hunger.
   If you have problems with your memory then you should probably check first if you are getting enough sleep.
   
3. Avoid stress.
   Stressful situations can also do harm to the brain's functioning.
   Stress can make it difficult for people to remember or memorize, so it's important to try always to relax.
   You can practice meditation, yoga, stretching, or deep breathing.
   It also helps when you think of happy thoughts often.
   Good mood and positivity helps put the mind always in the best condition.
   
4. Eat healthy.
   Eating right, and especially eating "brain foods" like foods rich in Vitamin B, E, niacin and thiamine can do your brain wonders.
   It is also beneficial to eat small meals throughout the day instead of eating 2-3 large meals.
   This prevents your blood sugar from dipping, hence helping your brain to function efficiently and to preserve your memory.
   
5. Eat fish and fish oil supplements.
   A lot of studies show that there is a link between fish and fish oils and memory.
   It is because of the omega3 and DHA in fish and fish oils that help boost and support the brains memory against memory loss due to ageing.
   DHA, which is one type omega3 fatty acid, most specifically provides majority of the fats that the brain needs, thus it is one of the things responsible for optimum brain functioning.
   Studies even reveal that serious degenerative brain diseases like Parkinson's and Alzheimer's can be prevented by taking fish oil supplements on a regular basis.
   

These are just the foundations of keeping your mind healthy and your memory in tiptop shape.
These will not work unless you give your time and full effort in following these healthy practices.
Consult your doctor if you want to learn more on how improve your memory works; and if ever you have a severe case of forgetfulness, ask for some advice and get yourself checked.
