According to a new study in the Proceedings of the National Academy of Sciences, lack of sleep over prolonged periods of time can lead to serious health problems like diabetes, obesity and heart disease.
Genes produce a constant supply of proteins
which our body uses to repair and replace damaged tissue, but a recent
experiment has revealed that after just a week of sleep deprivation some of
these stop working. If your body can’t replenish damaged cells and tissues
then it’s likely to lead to lasting ill health.
A week of normal sleep is said to be enough
to restore the affected genes to their normal pattern, but this study was only a week of sleep restriction
and participants were only restricted to five and a half or six hours a night and as Professor Colin Smith explains "Many people have that
amount of sleep for weeks, months and maybe even years so we have no idea how
much worse it might be.”
