According to reports, the government could tell the government how many hours of sleep each night should be spent.

Evidence on the relationship between sleep and health will be examined and recommendations made for people of different ages, according to The temperature.

The paper quotes a draft of a green paper on public health that should be published by Matt Hancock, secretary of health.

He said that much of the paper focused on obesity and smoking, but that it also referred to sleep.

according to The temperature, excerpts say, "As a first step, the government will review the evidence on sleep and health.

"This is to advocate for a clear national focus on recommended sleep times per day for people of different age groups and to increase awareness of key factors of sleep hygiene that may favor a healthy sleep. "

A spokeswoman for the Ministry of Health said they did not comment on leaks.

Earlier this year, a team of German scientists said that, in a study published in the Journal of Experimental Medicine, they discovered that sleep improves the ability of immune cells to reach their targets and fight infections.

The NHS currently recommends that an average person needs about eight hours of good quality sleep each night to function properly.

It warns that a lack of sleep can make people more prone to a number of medical conditions, including obesity, high blood pressure and heart disease.

Studies suggest that people who sleep less than five hours a night have an advanced risk of developing type 2 diabetes.
