In 10 seconds? Research suggests that “social jet lag” increases the chance of heart disease, can lead to obesity but also increases the risk of depression. Luckily, a consistent sleep pattern and revised meal times can be good counter-measures.
What is social jet lag as opposed to jet lag? With jetlag, you have trouble going to sleep at the right time when you find yourself in a new time zone. Social jetlag can be more chronic – it occurs when we sleep less on workdays and get up much later on our days off. It affects a lot of us, particularly shift workers and teenagers – the latter can even suffer from it when daylight saving time gets adjusted, just by 1 hour.
