The lack of sleep can reduce immunity

According to a new study by US scientists published on February 26, lack of sleep will have bad consequences for gene expression.

For a long time, many scientific studies have demonstrated that lack of sleep is directly related to the causes of cardiovascular disease, cognitive impairment of the brain and obesity.

Recently, American scientists have further studied the molecular mechanisms behind this phenomenon and concluded that sleep deprivation also seriously affects gene expression.

Gene expression of about 711 genes in a person will suffer from negative effects if for a consecutive week, the person only sleeps 6 hours or even less each night. These include genes involved in inflammation, immunity and ability to endure stress.

In addition, when compared to those who slept 10 hours a night, scientists also found that those who lacked sleep had the physiological rhythm of abnormal genes.

According to statistics, there are about 30% of US workers, equivalent to 40.6 million people, sleeping on average or less than 6 hours / night. About science recommends that a sleep considered ideal for adults is between 7-8 hours / night.
