If you are one of those people who is not crazy about bedtime, it is entirely possible that genetics are to blame for this.
A new discovery indicates that those who sleep less than average have an Adrb1 gene mutation, which results in them sleeping for two hours less.
The study was published in the scientific magazine Neuron, and was conducted by researchers at the University of California, who analyzed the genetics of a family who sleep less than what is considered normal.
The experiments continued on mice, where this mutation in their genes was also discovered. In mice, this mutation results in about an hour of sleep less.
It is likely that this mutation leads to less sleep due to neurological activity in the gene Adrb1 during sleep, where the activity of such a mutation is more powerful, and therefore causes disruptions at bedtime.
