Caffe'

[C3pO]

Io comunque é una settimana che ho eliminato del tutto il caffè. Perché mi é stato detto che io essendo molto bradicardica (35 battiti a riposo) dovrei sfruttare questo vantaggio. In effetti da quando non lo prendo prendo piu ho trovato un aumento di energia, dormo meglio la notte e mi alleno meglio. Non so quanto le sue cose siano collegate però

[tomaszrunning]

Hai descritto tutti questi vantaggi che il dott. Cherniske sottolineava nel suo libro!
se te la cavi bene con l'inglese, te lo mando via email (.epub)

@tomaszrunning si me la cavo molto bene con l'inglese. Ma é un libro di che genere?

[tomaszrunning]

É quello di quale si parlava qualche pagina fa. Hai letto thread?
il titolo é Caffeine Blues
Pericoli di droga n°1 dei Usa
Dammi tuo email in MP e ti mando il libro

The fact is that caffeine never gave you energy. It stimulated your nervous system and adrenals, and that’s not energy, it’s stress. To get this point across to my clients, I ask them to imagine going to a bank for a loan. The loan officer is superfriendly and readily agrees. But as you’re leaving the bank, you read the fine print, which lists the interest rate at 75 percent! Would you be interested in such a loan? Likewise, the “energy” you receive from caffeine is really just a loan from your adrenals and liver, and the interest is extremely high. At some point (referred to as adrenal exhaustion) you may find yourself “bankrupt” and unable to repair the damage.
Stress—and by that I mean unresolved or unmanaged stress (perhaps more properly called distress)—is a silent saboteur of health.(...) Experts agree that stress is a factor in most diseases, and a major factor in disorders such as anxiety, insomnia, depression, ulcers, rheumatoid arthritis, headache, hypo-glycemia, asthma, herpes, hypertension, and heart disease. And yet, if you walk into most hospital waiting rooms, you’ll find a coffee machine. Perhaps that’s because we don’t understand how stress ruins our health.

Your Sleep Cycle
Among researchers, sleep is an extremely hot topic. Entire journals are devoted to the subject, and sleep centers are opening in research facilities around the world. This explosion of interest has been fueled mainly by neurobiologists who are starting to unravel the complex way in which the brain directs the healing powers of the body. And one of the most startling discoveries has to do with what goes on while you sleep. When you begin to understand these mysteries, you’ll never look at a cup of coffee in quite the same way. That’s because sleep can be a youth-restoring, powerfully rejuvenating, deep healing experience—or, it can be merely a continuation of the day’s tension, conflict, and frustration. For most of us, the difference is a drug called caffeine

As you may know, a night’s sleep is divided into roughly ninety-minute cycles in which brain activity changes dramatically. In Illustration 3, you can see that during each cycle, the brain goes through four stages, from S1 (shallow sleep) to S4 (deep sleep). Most people are familiar with Si because that is when we dream and have rapid eye movement (REM). But in reality, each stage provides the body and brain with essential repair, rejuvenate, and rebuild benefits. Dreams, for example, are absolutely critical for maintaining mental and emotional health. We don’t know why, but if you prevent a person from dreaming for just a few nights, that individual will start to experience clear signs of psychosis. It was once thought that caffeine enhanced dream sleep, or at least lengthened the S1 phase of the sleep cycle. But recent research shows that caffeine (and numerous other drugs) can disrupt this crucial function. A. N. Nicholson, A. J. Belyavin, and P. A. Pascoe, “Modulation of Rapid Eye Movement Sleep in Humans by Drugs that Modify Monoaminergic and Purinergic Transmission,” Neuropsychopharmacology, June 1989;2(2):131–43
As important as dreams are to the mind, deep sleep (S4) is essential for the health of the body. Interestingly, scientists have learned a great deal about deep sleep from studying coma patients. The purpose of coma, you see, is to deactivate all nonessential functions of the body and brain in order to devote every possible ounce of energy to the task of healing. Likewise, the body uses deep sleep to mobilize all available resources for healing and rejuvenation. During S4 sleep, there is a massive creation of new cells throughout the body. Every tissue benefits, but most activity is centered on building immunity and restoring the nervous system. We all know how wonderful we feel after a good night’s sleep. That’s because deep sleep provides a level of rest that cannot be obtained in any other way. In a very restful night, you may experience deep sleep at two and possibly three phases. But when there’s caffeine (or its metabolites) in your bloodstream, you are unlikely to experience deep sleep at all.

Arand, “Metabolic Rate and Restorative Function of Sleep,” Physiology and Behavior, April-May 1996;59(4-5):777-82.
You must understand that insomnia is not the issue. Insomnia (the inability to fall asleep) deals only with the quantity of sleep. The real issue here is sleep quality. Caffeine tolerance may allow you to fall asleep, but if S4 sleep is disrupted, you will wake up feeling tired instead of renewed.
Research shows that people who consume more than 250 milligrams of caffeine per day tend to have poor sleep quality

In one study, habitual coffee drinkers were allowed to drink coffee until midday (in order to prevent withdrawal). Later in the day, they were given either caffeine or placebo, and on days when they received placebo, their sleep quality improved significantly. As a result, they felt much better the following day.

@tomaszrunning fantastico! Questo spiega un sacco di cose. Praticamente il mio era un circolo vizioso. Dormivo poco e male perché bevevo il caffe, cosi ero stanca e allora bevevo il caffe per stare sveglia.
Certo pero adesso da quando ho smesso certi riposini il pomeriggio mi faccio, che neanche un bimbo di 2 anni

Ciao a tutti
Ho una domanda per quanto riguarda caffè e anemia. Io ho il ferro sempre molto basso nonostante i cicli di Ferrograd (ora ferro 16 e ferritina 4). Il medico non mi ha mai dato nessuna indicazione mentre il nutrizionista mi ha sconsigliato il caffè soprattutto dopo i pasti in quanto impedisce l'assimilazione del ferro.
Ma anche decaffeinato? O quello posso (lo adoro dopo cena e al mattino!)
Grazie a tutti

[Giu]

Aggiungo anche che mi ha vietato il cappuccino al mattino (e per me è un dramma) in quanto il caffè impedisce anche l'assimilazione del calcio contenuto nel latte...possibile?
Anche cappuccino decaffeinato o d'orzo vietati per lo stesso motivo!
Ma allora non dipende dalla caffeina? Non mi è chiaro....

[fujiko]

@giu io mi base soltanto sulla mia esperienza e non c'è nulla di medico ma ti dico che, avendo sempre sofferto col ferro molto basso, nel lungo periodo in cui ho drasticamente diminuito il caffè e comunque da quando ho preso la misura di prenderlo solo almeno due ore dopo il pasto, i livelli sono migliorati a parità di altre condizioni.
