In fact, TSH is one of the well-known hormones, such as cortisol, melatonin, prolactin, etc. that change as part of the daily circadian rhythm. TSH peaks during the night and remains lower during the day. The fact that serum T4 and T3 levels remain relatively constant despite this change is intriguing, though again, there is likely a good deal of regulation we don't understand and that is difficult to measure at an intracellular level, and it may have to do with some of the regulation I talk about in a couple of paragraphs.

Circadian rhythm in the number of vasopressin-containing neurons in the human suprachiasmatic nucleus (SCN) of *(A) young subjects (<50 years of age)* and *(B) elderly subjects (>50 years of age)*. The black bars indicate the night period (22:00–06:00 h). The general trend in the data is enhanced by using a smoothed double plotted curve and is represented by mean ±SEM values. Note the circadian rhythm in the SCN of young people, with low values during the night period and peak values during the early morning.

Emodialisi cronica: decessi più probabili al mattino
Nei pazienti sotto emodialisi a lungo termine, i decessi avvengono più di frequente nelle ore del mattino di quanto si potrebbe attribuire al caso. Si osserva infatti una variazione circadiana nella mortalità della popolazione non in dialisi, e gli eventi cardiovascolari avvengono più frequentemente al mattino, ma non era mai stato finora accertato se ciò avvenisse anche nei pazienti in emodialisi. La presenza di sintomi medici durante l'ultima sessione dialitica è inversamente correlata alla probabilità di mortalità mattutina in questi pazienti. Sono necessari ulteriori studi per esplorare i meccanismi che portano a questo ritmo circadiano, e valutare interventi atti a ridurre il rischio di eventi mattutini.

sono in disaccordo perche' il caso non puo' essere spiegato come confermato dall'articolo: The association of metabolic syndrome and Chlamydia pneumoniae, Helicobacter pylori, cytomegalovirus, and herpes simplex virus type 1: the Persian Gulf Healthy Heart Study.
