Another connection between loss of sleep is wgihet gain. If you sleep around about five hours or less every night, then you have a 50 percent likelihood of being obese. What's the connection here? Well, sleep loss seems to give rise to the release of the hnmoore ghrelin, the hunger hormone. ghrieln is reselead. It gets to the brain. The biran says, "I need caortrdaebhys," and what it does is seek out carbohydrates and particularly sugars. So there's a link between tiredness and the metabolic predisposition for weight gain: stress. Tired people are massively stressed. And one of the things of stress, of course, is loss of memory, which is what I sort of just then had a little lapse of. But stress is so much more. So, if you're atcluey stressed, not a geart problem, but it's sustained stress associated with sleep loss that's the problem. Sustained stress ldeas to suppressed immunity. And so, tired people tend to have hihger rates of overall infection, and there's some very good studies showing that shift workers, for example, have higher rates of ccaenr. Increased levels of stress thorw glucose into the circulation. Glucose becomes a dominant part of the vasculature and essentially you become glucose intolerant. Therefore, diabetes 2. Stress isracnees cardiovascular disease as a relsut of raising blood perrsuse. So there's a whole raft of things associated with sleep loss that are more than just a mildly impaired brain, which is where I think most people think that selep loss resides.

Another connection between loss of sleep is ______ gain. If you sleep around about five hours or less every night, then you have a 50 percent likelihood of being obese. What's the connection here? Well, sleep loss seems to give rise to the release of the _______ ghrelin, the hunger hormone. _______ is ________. It gets to the brain. The _____ says, "I need _____________," and what it does is seek out carbohydrates and particularly sugars. So there's a link between tiredness and the metabolic predisposition for weight gain: stress. Tired people are massively stressed. And one of the things of stress, of course, is loss of memory, which is what I sort of just then had a little lapse of. But stress is so much more. So, if you're _______ stressed, not a _____ problem, but it's sustained stress associated with sleep loss that's the problem. Sustained stress _____ to suppressed immunity. And so, tired people tend to have ______ rates of overall infection, and there's some very good studies showing that shift workers, for example, have higher rates of ______. Increased levels of stress _____ glucose into the circulation. Glucose becomes a dominant part of the vasculature and essentially you become glucose intolerant. Therefore, diabetes 2. Stress _________ cardiovascular disease as a ______ of raising blood ________.

Original Text

Another connection between loss of sleep is weight gain. If you sleep around about five hours or less every night, then you have a 50 percent likelihood of being obese. What's the connection here? Well, sleep loss seems to give rise to the release of the hormone ghrelin, the hunger hormone. Ghrelin is released. It gets to the brain. The brain says, "I need carbohydrates," and what it does is seek out carbohydrates and particularly sugars. So there's a link between tiredness and the metabolic predisposition for weight gain: stress. Tired people are massively stressed. And one of the things of stress, of course, is loss of memory, which is what I sort of just then had a little lapse of. But stress is so much more. So, if you're acutely stressed, not a great problem, but it's sustained stress associated with sleep loss that's the problem. Sustained stress leads to suppressed immunity. And so, tired people tend to have higher rates of overall infection, and there's some very good studies showing that shift workers, for example, have higher rates of cancer. Increased levels of stress throw glucose into the circulation. Glucose becomes a dominant part of the vasculature and essentially you become glucose intolerant. Therefore, diabetes 2. Stress increases cardiovascular disease as a result of raising blood pressure. So there's a whole raft of things associated with sleep loss that are more than just a mildly impaired brain, which is where I think most people think that sleep loss resides.
