A study by the University of California shows that six hours and 25 minutes is enough sleep for a person.

This was done through observation of the sleep habits of three groups of hunter gatherers and decided six to seven hours is the natural amount.

The findings show that people who slept an average of six hours and 25 minutes possess good health, low rates of obesity, good levels of blood pressure and healthy hearts.

Scientists observed that modern technology and its commotions are not the root cause of people getting less sleep.

Three examined societies of hunter-gatherers included; the Hadza in northern Tanzania, south of the equator, the Kalahari San in northeast Namibia, and the Tsimane who live close to the Maniqui River in Bolivia. The societies which were selected do not live in the modern day life of technology and were considered appropriate for the study because of having an ancient lifestyle.

Ghandi Yetish, the study’s lead author, said: “There’s this expectation that we should all be sleeping for eight or nine hours a night, and if you took away modern technology, people would be sleeping more.

“But now, for the first time, we are showing that’s not true.”

The people involved in the study stayed awake for an average of three hours and 20 minutes after dusk despite the absence of technology.

The tribes also tended to wake up at the coldest point of the morning because the study shows that temperature seems to regulate sleep duration and timing.

Professor Jerome Siegel said: ‘The argument has always been that modern life has reduced our sleep time below the amount our ancestors got but our data indicates this is a myth.’

He continued: “In most modern environments, people are sleeping in a fixed temperature, even if it’s reduced from daytime levels.

“It may well be that falling environmental temperature is integral to sleep control.”
The findings are presented at the Neuroscience 2015 conference and the results of University of New Mexico’s doctoral candidate Gandi Yetish are stated in “Natural Sleep and its Seasonal Variations in Three Pre-industrial Societies.”

The researchers from the UNM Department of Anthropology, the University of California, Santa Barbara, Yale University, Hunter College, the University of the Witwatersrand in Johannesburg, South Africa, the University of California Los Angeles, the VA Greater Los Angeles Healthcare System, and the Brain Research Institute at UCLA all worked cooperatively to get the findings.

“We have seen in these two weeks not much engagement in science but a lot of engagement in business. There has been no movement on the big issue of reducing emissions but instead a proliferation of proposals on new market mechanisms.” Ambassador Solon said.

“All the reports show a problem of science and a problem of leadership. We need deep cuts and we need developed countries to take the lead That is why we propose an ad-hoc high level meeting dedicated to the issue of increasing targets.” Ambassador Solon said.

Reflecting on the two weeks of talks the Ambassador outlined concerns regarding the future of the Kyoto Protocol, with new market proposals, and hope for consideration of the rights of nature.

“The lack of ambition for Kyoto Protocol worries us very much. Countries are abandoning the international rule based system. Some developed countries are proposing effort for the second period that is even less per year than they are doing now.” Ambassador Solon said.

“We have seen proposals for markets for the oceans, so called ‘blue carbon’ we are surprised and concerned by these. The problem with the reference level for markets such as these is that it is based on assumptions that are not real. And there is the great possibility that the new market mechanisms will just create more hot air.” Ambassador Solon said.

“With parameters that are not real countries try to get a bigger share of certificates of reductions and in that way instead of developing new sources of finance we will develop new sources of deterioration of our natural systems.” Ambassador Solon said.

“Many of the proposals that we have had advanced have had interesting discussions such as the issue of the rights of nature an the integiry of ecosystems. This is key for us because we are all part of a system and until now we have not recognized the limits to our exploitation of natural resources that will affect precisely that system.” Ambassador Solon said.
