|Irregular sleep patterns cause 'social jet lag'
Irregular sleeping patterns could adversely affect our health. So says a study in The European Journal of Nutrition. The study suggests sleeping at different times could increase the number of harmful species of bacteria in our stomach. Changing the times we sleep on workdays and at weekends changes our internal body clock. Researchers call this "social jet lag". It leads to eating more sugary snacks, less fruit and vegetables, and a poorer diet. The lead author of the study said social jet lag can encourage bacteria that are bad for our health.
