Traveling across time zones causes disruption to the normal circadian rhythms and social schedules because of travelers' shift in time. As the endogenous circadian timing system adapts slowly to new time cues, the phase relationship between biological rhythms and external time cues are out of synchronization for a period of time. This disturbance of circadian rhythms has been shown to impair ph...

Introduction: It has been known for a long time in the French-speaking, but not the English-speaking literature that travel can exacerbate pre-existing psychosis. The purpose of this article was to review the literature on this subject and present recommendations for prevention. Methods: For this narrative review of the literature on travel risks in indivi...

This paper investigates the relationship between electricity consumption and economic growth by using Autoregressive Distributed Lag (ARDL) bounds testing approach and vector error-correction models (VECM) in Cameroon, Cote D'Ivoire, Congo, Ethiopia, Gabon, Ghana, Guatemala, Kenya, Senegal, Togo and Zambia for period 1970-2010. The ARDL results show that there is cointegration relation between ...

Alleviation of jet lag by melatonin: preliminary results of controlled double blind trial Jet lag is an ill defined phenomenon resulting from rapid flight across several time zones.' It is considered to be due to desynchronisation of circadian rhythms, such as the sleep-wake cycle, with local time and to lack of sleep. ' A means of rapidly resynchronising body rhythms to local time would benefi...
