A physical trick that helps you remembering to do things later.
It fights the stress hormone which damages the brain’s ability to learn and remember.
Afterwards, people responded faster and had stronger short-term memory.

The caffeine in two cups of coffee is enough to jump start short-term memory.
Short-term memory is the type used for keeping things in consciousness for a short period.
Dr. Koppelstätter, the study’s first author, said it is…
“…like looking up a telephone number in the phone book and storing the number until you’ve dialed it.”
For the research, 15 people were given either the equivalent of two cups of coffee or a placebo, then asked to do a standard memory test.
Those given caffeine responded faster and had stronger short-term memory.
Brain scans also revealed that caffeine was linked to higher activation of the frontal lobes, where working memory is partly located.
Dr. Koppelstätter said:
“What is exciting is that by means of fMRI we are able to see that caffeine exerts increases in neuronal activity in distinct parts of the brain going along with changes in behavior.”
The study was published in the journal Neuroimage (Koppelstätter et al., 2008).

How we breathe affects brain activity, memory and the emotions.
How we breathe affects brain activity, memory and the emotions.
Breathing in through the nose boosts memory because inhaling stimulates the brain.Scientists have shown for the first time how the rhythm of breathing affects electrical activity in the brain.People were more likely to remember objects they had encountered while breathing in than breathing out, the study results showed.While breathing in, people were also quicker to identify a fearful face.Mouth breathing did not have the same effect — it had to be inhaling through the nose.Dr Christina Zelano, the lead author, said:“One of the major findings in this study is that there is a dramatic difference in brain activity in the amygdala and hippocampus during inhalation compared with exhalation.When you breathe in, we discovered you are stimulating neurons in the olfactory cortex, amygdala and hippocampus, all across the limbic system.”The scientists first came across this curious phenomenon when studying seven patients with epilepsy.Recordings of their brain activity showed it changed with breathing.For the study, 60 people were shown faces on a computer screen and later objects they had to remember.There was evidence of the same curious changes of brain activity with breathing.Rapid breathing may give us a cognitive advantage in some situations, said Dr Zelano:
“If you are in a panic state, your breathing rhythm becomes faster.As a result you’ll spend proportionally more time inhaling than when in a calm state.Thus, our body’s innate response to fear with faster breathing could have a positive impact on brain function and result in faster response times to dangerous stimuli in the environment.”Dr Zelano said it also provided insight into how practices like meditation affect the brain:
“When you inhale, you are in a sense synchronizing brain oscillations across the limbic network.”The study was published in the Journal of Neuroscience (Zelano et al., 2016).
What if your baby brain held onto memories, but you just can’t retrieve them?
Why you should celebrate your poor memory.
Memory loss risk reduced by this common drink.
Research uncovers striking brain differences in depressed individuals.
The common drink that may protect the brain against memory loss.
The common drink that may protect the brain against memory loss.
Drinking orange juice regularly is linked to a 47 percent lower risk of memory problems with age, research suggests.
Berry fruits, orange and red vegetables and leafy greens may also help protect against memory loss.
The results come from a study that followed 27,842 men for 20 years.
Every four years they were asked about the foods they ate and were given tests of their memory and thinking skills.
They were also asked questions including:
Those that had six servings of fruit and vegetables a day were 34% less likely to experience poor thinking skills later on.
Eating more fruit and vegetables in midlife was linked to better cognitive health later on — even if the men stopped eating fruit and vegetables.
Dr Changzheng Yuan, study co-author, said:
“One of the most important factors in this study is that we were able to research and track such a large group of men over a 20-year period of time, allowing for very telling results.
Our studies provide further evidence dietary choices can be important to maintain your brain health.”
The study only showed an association, it does not prove causation.
The study was published in the journal Neurology (Yuan et al., 2018).
