Scientists have identified the gene responsible for controlling the length of time for which an individual sleeps and why some have their own internal alarm clock. Karla Allebrandt and her team from the Ludwig Maximilians University of Munich identified a gene called ABCC9 that can reducethe length of time we sleep.
The discovery is expected to explain why light sleepers, such as Margaret Thatcher, are able to get by on just four hours shut-eye a night.
The researchers then analysed their answers, as well as participants’ genes.
They discovered that people who had two copies of one common variant of ABCC9 slept for “significantly shorter” periods than people with two copies of another version.
