5 things you should never forget

Whether it's a name, a day or an instruction, there's always something new in it to remember. But perhaps you will feel your little brain cells do not have enough room to contain the latest information. Unfortunately, we do not have external hard drives. But don't be so desperate. Some recent studies have revealed how memory works along with what you can do to improve memory.

1. Additional memory

You don't want to do what you learn today? Then go to sleep. Ideal 90-minute sleep will help you record what happened and what you learned during the day. When you sleep at night, the brain creates memories of the event that day.

But when the brain contains too many long-term memories, you will have trouble remembering new events.

Scientists once thought that memory improves when new neurons are created in code - the memory formation in the brain. In fact, the brain has fewer neurons than normal in the area of ​​fish code can also have better memory.

Recent studies have found that migraine, music, habits, zinc and thinking can improve one's memory.

2. Tired memory

According to a study that uses images that show that transformed pictures can distort the way you think about the past. The first famous photo was a picture of a man blocking a convoy of tanks in Tiananmen Square in 1989 with a large number of viewers added to the original photo. The second photo was about the anti-war protest in Rome in 2003, the photo was given with anti-riot police and masked protesters. Viewers of these two transformed photos will remember the more violent past images, with more losses than those who viewed the original. The cropped image viewer also feels uneasy when participating in such activities in the future compared to those who do not edit photos.

This result is not surprising. Participants in previous studies also thought that imaginary images were real.

3. Aging memory

Mostly due to functional impairment of the coded area by age, older people often suffer from memory loss over time. This limits the ability to recall vivid memories, things seen, heard or perceived from past events. And because we use the same brain to imagine and remember, older people not only become forgetful but also have trouble remembering hypothetical situations. But some older people know how to limit memory decline by maintaining a positive social life, they always believe that they still have good memory.

Interestingly, the factors of dementia - such as obesity, excessive stress and high cholesterol - coincide with the factors of cardiovascular disease. Scientists found that one of the risk factors would double the likelihood of developing dementia. And if all three risk factors are present, the risk of dementia increases six times. Controlling these three factors can help protect the heart and mind. But also, we cannot deny the effects of genes and age.

Older people can improve their memory within a few weeks by eating well, exercising and keeping the mind alert. To prevent decreased blood glucose levels, older people often eat 5 meals a day. Meals should be full of cereals, antioxidants and omega-3. During a young age, we should practice brisk walking every day, practice relaxation exercises, use mental stimulants that benefit the brain. Regular mental exercises have been shown to reduce the risk of dementia by half.

4. Memory and knowledge

Studies have shown that the more you know, the easier it is to learn related topics. The group of senior citizens has a higher level of expression than the less educated peers in the mental status tests.

But the ability to remember what they learned seems to decline at a faster rate. If you know more, forget more and more. But don't expect that your education can compensate for your youth's ability to fight dementia.

People with good memory will have to sacrifice this advantage when sweating in pressureful situations. For example, when worrying about a mistake in the test will waste brain activity while it could be used to recall a certain sound word or to calculate the surface area of ​​the sphere.

5. Remove memories

Sad things even have a longer lasting impact than those that are not stored in the brain for a long time. The recollection of events makes an unhappy memory seem to be more accurate than the memories of a happy time in our lives. That's because those unpleasant memories force our brains to focus on a specific detail.

Trying to forget a sad memory is possible, but requires a lot of effort. If successful, your brain will for the first time deny the sensory aspect of memory before eliminating real memories.

And don't forget from an evolutionary perspective, painful moments often have a longer lifetime. The survivability of a species is enhanced by its ability to remember treacherous situations to avoid it when those situations happen again.
