A Canadian study has found that women have a circadian rhythm, which runs between 1.7 and 2.3 hours ahead of their male partners.

This means they are likely to feel more tired earlier in the evening than men, according to the study in the journal Proceedings of the National Academy of Sciences.

Such differences are mainly due to the influence of our sex hormones, says Dr. Adam Taylor, a senior lecturer in anatomy at Lancaster University Medical School.

'These hormones can affect our health in everything from how fast our hair grows to how quickly we blink and even how rapidly we digest food and alcohol.'
