PHYSICAL ACTIVITY AGAINST INSOMNIA... DOES IT WORK ?

Insomnia and poor quality sleep can affect many areas of your life and health, included work performance.

To fight insomnia without resorting to drugs, it is very important to perform regular physical activity. However, this is a “sweet” remedy, with long-term effects: benefits of physical activity in fact begin to be evident after at least four months ... A time span that may seem too long for those affected by the problem of "white nights" ... almost .. 

So, we give an advice to all the insomniacs: don’t discourage yourself if, after having joined a fitness club, instead of sleeping better, it is even harder to fall asleep…

It is a physiological fact, especially in the case of physical activities carried out in the evenings. 

Indeed, it is very important that, even though you feel tired, you persevere with your plan ... it will take a bit of time ... but then “the road will be downhill”!

CAFFEINE AND LONG-TERM MEMORY: GOOD NEWS !

Caffeine intake of 200 mg /day can enhance long-term memory ...

Again good news about caffeine, a molecule already known both as a cognitive enhancer and as a neuroprotectant.

According to a study published in the journal Nature Neuroscience, a 200 mg dose of caffeine after a learning session would be able to strengthen long-term memory .

Assuming that an espresso contains an average of 60-120 mg of caffeine, consumption of 2-3 cups of coffee a day may therefore be useful to strengthen our long-term memory .

But just be careful ... an" overdose " of coffee , as well as being able to cause unpleasant side effects, do not make us monsters of memory: memory effects are not enhanced by increasing the dose of caffeine from 200 mg to 300 mg .

In addition, the assumption of caffeine only an hour before a memory test showed no improvement, therefore caffeine can not be considered a “rescue remedy” for those people who wish to enhance their short-term memory after a night spent on the books just before an examination.

Maybe this evidence is the first step towards a profitable use of caffeine against diseases that seriously affect memory ... we hope !
