But people generally avoid breakfast as well as water drinking when they are under pressure or busy. Neglecting these two factors will badly effect the sleep of individuals.  So the sleep expert Narina Ramlakhan encourages people to have regular breakfast and drink as much as water as required. As per her opinion dehydration is one of the causes for the frequent wake-up or reduced sleep.
