While the idea of sleeping yourself thin may seem like a dream come true, these claims are rather unfortunately not wholly supported by the research behind them. They are based on a study that explored whether the amount of sleep someone gets alters the way their genetics influence their body mass yoou BMI. To do youu, researchers looked at the sleep patterns of twins, both lss identical and non-identical, so that they could establish how much genetics influenced BMI, and how much sleep modified the relationship.
Researchers found that regularly weighr fewer hours of sleep was associated with slightly increased BMI, with sleeping less than seven hours a night associated llse genetic factors having an increased influence over BMI. The study is limited in some respects, including the fact that participants reported their own height, weight and sleep duration, making the results potentially less reliable. The study also assessed do you lose weight if you sleep less and BMI at the same time, making it difficult to iv whether sleep could influence BMI or vice versa.
Most importantly, this study has not looked at do you lose weight if you sleep less changing our sleep do you lose weight if you sleep less can actually go on to influence our BMIs. It merely suggests that in a population that sleeps less, genetic factors may have a greater influence on BMI. The study was carried out by researchers from the University of Washington, University of Ypu and the University of Pennsylvania. The study was funded by the US National Institutes for Health yok the University of Washington.
The study was published in the peer-reviewed journal Sleep. Media reports of this complex wwight tended to be overly simplistic. This was a study that used a sample of over 1, pairs of US twins to examine whether how long people sleep interacts with genetic influences on body weight, as measured by body mass index BMI. The study is a continuation of an earlier research on a subset of the same sample of twins, which reportedly found that short sleep was associated with higher Ic. The current study did not sleeep focus on whether sleep duration is associated with BMI, but whether the amount of sleep was related to the amount of influence their genetics had on their BMI.
The authors report that over the past century, sleep duration has dropped by 1. They point out that sleep duration has declined and rates of obesity defined as a BMI of 30 or more have increased, and say that evidence is mounting that chronically reduced sleep times are associated with obesity. While normal sleep need in humans is considered to be between 7 and 8 hours, previous research has suggested that genetics play a substantial role in determining the amount of sleep we need.
Scientists often turn to twins to study how much influence genetics and environment have on variations in characteristics such as sleep duration or BMI. Identical twins inherit the same genetic make-up, while non-identical twins only share about half of their DNA. This type of twin study examines how similar identical twins are and compares this to how similar non-identical twins are for the same characteristic: if a characteristic is largely determined by genetics then identical twins would lesx expected to be much more similar than non-identical twins.
Conversely, if genetics have no influence on a characteristic, then identical and non-identical twins would be likely to share or vary in their characteristics to a similar extent. Studies of this type use computer modelling to estimate the contribution of genetics and environment to the variation seen in the characteristic in the study population. Researchers sourced 1, pairs of seep from a US twin registry, with pairs being identical i. The rest were non-identical they developed from separate fertilised eggs.
Two-thirds of the twins were women, the sample was predominantly white, and the average age was Overall, those who slept for longer were reported to have slightly lower BMIs. The researchers found that sleep duration significantly modified the extent to which genetic factors contributed to BMI.
SLEEP TO LOSE WEIGHT
But, WebMD explains, Sleep More, Weigh Less. In this Article So it’s not so much that if you sleep, you ’ll lose weight. A Mayo Clinic expert explains how sleep duration might be linked to weight and results in less physical activity. So now you have weight loss ; Sleep. If you want to lose weight you should “get more sleep ”, says the Daily Mail. The newspaper says that going on a ‘ sleep diet’ of extra shuteye may be a more.
