With the change of season the symptoms of physical and mental fatigue re-emerge: listlessness, memory loss, reduced concentration, fatigue, which can strike, however, even in the case of increased psychophysical stress. This is not a true pathology, but signals that the body sends us when it needs a burst of energy, or tonics capable of intervening on physiological processes, increasing resistance against environmental and psychophysical stress, to deal with load situations extraordinary.
Getting out of the long winter is very difficult and, in fact, the transition from a harsh climate to a warmer one, variable and windy, puts a strain on our body, which had found the right balance in adapting to the winter cold. After this period of forced rest, our body needs time to recover and in the meantime it puts into circulation toxins and waste accumulated during the winter.
A balanced diet rich in mineral salts and vitamins and even a little relaxation can prove useful to regain wellness. A further help can also come from nature thanks to plants that act as tonics, performing an excellent adaptogenic action on the body.
These tonics are able to intervene on physiological processes, increasing resistance against environmental stresses in order to better adapt the organism to extraordinary loading conditions.
One of these tonic with interesting properties is guarana, a climbing plant of Brazilian origin in which seeds contain considerable amounts of caffeine, theophylline and theobromine (the latter being the stimulating substance present in cocoa).
Guarana fights mental fatigue, as its neurotonic action on the central nervous system stimulates cognitive function and attention. For this reason it is indicated in the changes of the season especially when the pressure is low and there are the symptoms of fatigue, for students before the exams and for those who must face pressing work rhythms.
Therefore, guarana performs an action in some respects similar to that of coffee, tea and chocolate, with the difference that, being two to five times richer in caffeine, it has decidedly more significant effects. It is considered an excellent tonic in the category of stimulants both physically and cerebrally.
At the physical level, it makes the sugars more available for muscular activity, which is particularly useful for those who carry out intense sporting activities. At the cerebral level, it stimulates memory and attention, at the same time reducing the feeling of fatigue and tiredness.
But be careful not to abuse it, in fact, just like coffee, guarana can have several side effects . If taken in excessive doses or for too long periods, it can cause irritability, tachycardia, insomnia and tremors. To avoid these side effects it is sufficient not to exceed the daily doses.
