Noch dramatischer ist die Situation natuerlich in geschlossenen Wohn- oder Bueroraeumen mit unzureichender Frischluftzufuhr. Der Trend zu mehr Waermedaemmung in Gebaeuden, der dem Klimawandel entgegenwirken soll, verschlimmert unsere Probleme also noch.Increased CO2 concentration in inhaled air decreases the pH of blood, which in turn spills over to cerebrospinal fluids. Nerve cells in the hypothalamus that regulate appetite and wakefulness have been shown to be extremely sensitive to pH, doubling their activity if pH decreases by 0.1 units. We hypothesize that an increased acidic load from atmospheric CO2 may potentially lead to increased appetite and energy intake, and decreased energy expenditure, and thereby contribute to the current obesity epidemic.
