According to scientists writing in the scientific journal Current Biology, the time change abruptly disrupts the internal body clock's adaptation to seasonal variations in the alternation of day and night and only allows this to resume - far too late - in the autumn.
And in humans, we call it the "body clock."
On a normal working day, only 7 % of people get enough sleep and are able to follow their internal body clock.
Shift work. Shift work is extraordinary, perhaps 20 percent of the working population, and the body clock does not shift to the demands of working at night.
So fine, we have a body clock, and it turns out that it's incredibly important in our lives.
So when the poor old shift worker is going home to try and sleep during the day, desperately tired, the body clock is saying, "Wake up. This is the time to be awake."
The hotel's unique 24-hour room service menu, Body Clock Cuisine, will suit Sofitel London Heathrow's international clientèle, as the menu has been specifically designed to include items that assist the body to adjust to the demands of international travel.
People's internal body clock causes certain aspects of their behaviour and many of their bodily processes to follow cycles.
