Overseas health insurance customers might be interested to learn that eating patterns can be disturbed by a lack of sleep.
According to Tam Fry, chairman of the Child Growth Foundation, not getting enough sleep will "upset the hormones which regulate eating and therefore you get variations of eating".
His comments follow research published in the British Medical Journal, which found that there is an increased risk of obesity among young children who do not get enough sleep.
Mr Fry said that these findings were unsurprising, adding: "If you are not sleeping properly, you are very probably snacking because you think 'oh I'm trying to get to sleep, I'll have a biscuit or I'll have a packet of crisps or something, while I'm trying to get to sleep.
"What you're then doing is eating snack food which is quite often less than healthy because it is energy dense. Those are reasons why, [for] children particularly, lack of sleep might be affecting their weight gain."
