I recorded this last night and have just finished watching it.
Lots of info about sleeping (or not) in general but there were two interesting points about poor sleep. If I understood it correctly...
1. Leads to maintained high levels of glucose in your blood, instead of the levels going down during your sleep. Apparently this can lead to obesity and one of the types of diabetes (forgot which one - goldfish memory again)
2. The micro organisms in your stomach actually become more efficient and absorb more of the food in your stomach then they would ordinarily.
If you're interested, it is here for about a month...
Like we didn't have enough to think about
