Dormir de menos pode aumentar cintura

https://www.forbes.com/sites/daviddisalvo/2017/07/30/shorting-yourself-on-sleep-could-be-adding-to-your-waistline/#38c12b5de067

Citando:
"The study of 1,615 adults found that people who slept an average of six hours a night had a waist circumference three centimeters larger than those who slept nine hours a night (that’s about 1.18 inches). The short sleepers also had a higher BMI on average and lower HDL cholesterol (the so-called “good cholesterol” number that ideally should be higher).

Participants had blood samples taken and their waist circumference, weight and blood pressure recorded. Sleep times fell into three categories: average of about 6 hours, average of about 7.5 hours, and average of about 9 hours. Across the board, the 6-hour group had worse outcomes than the other two groups."
(...)
"The reasons why this is true are a topic of ongoing discussion, but two strong evidence-based possibilities are: (1) sleep deprivation handicaps self-control, little by little, resulting in food choices that pack on weight over time, and (2) lack of sleep, even in small amounts each night, disrupts hormones that regulate appetite, inducing hunger and triggering nighttime cravings that result in more weight gain."

Benefícios do exercício físico "mentais"?

Basicamente, nada como ser positivo:

Citação:
"Apparently, just thinking that you’re not exercising as much as you should may be harmful, too. In a new study in the journal Health Psychology, people who thought they were less active than their peers had a greater chance of dying younger—even if their actual activity levels were the same.

The research suggests that the health perks of exercise may come not just from the physical movements, but also how people think and feel about them, as well. In other words, people who feel like slackers may not be getting all the benefits they should be from their workouts."

Porque é que sou mais picado que os outros?

Se bem que o que é verdade na Irlanda pode não o ser aqui e repetindo a notícia para compilar uma lista completa de motivos conhecidos pelos quais algumas pessoas são mais picadas que outras:

http://www.irishnews.com/lifestyle/holidays/2016/06/01/news/how-to-avoid-and-treat-mosquito-bites-on-holiday-542874/

Quoting:
"An estimated 10-20 per cent of people are highly attractive to mosquitoes and consistently get bitten more often than their counterparts.

• Research suggests that mosquitoes are attracted to exhaled carbon dioxide, as well as chemical compounds secreted in skin and sweat, including lactic acid, uric acid, ammonia, steroids, and cholesterol to name a few. 
• Certain bacterial species that naturally inhabit human skin, e.g. Staphylococcus epidermidis, make individuals more attractive to mosquitoes whilst others e.g. Pseudomonas aeruginosa, appear to have the opposite effect. 
• Research also suggests that certain blood types are more attractive to mosquitoes than others. A large number of the population secrete saccharides or sugars through the skin dependant on their blood type that mosquitoes are able to sense. 
• Studies suggest that mosquitoes seem to prefer those with Type O blood and land on skin with Type O blood nearly twice as often as those with Type A.
• Mosquitoes are also attracted to dark colours such as black and navy blue, as they use vision along with scent to locate their targets. It is best to dress in light colours such as white or pastels to reduce the risk of this.
• Pregnant women are more susceptible to bites. This is likely due to the fact that they exhale relatively more carbon dioxide and have a higher resting body temperature."

Homeopatia ou não homeopatia?

Provavelmente não, ver a história:
https://www.economist.com/blogs/economist-explains/2014/04/economist-explains?fsrc=scn/fb/te/bl/ed/whyhomeopathyisnonsense

Citando:
"The history of homeopathy – literally, “similar suffering” – dates back to the late 18th century. Samuel Hahnemann, a German doctor, was unimpressed by contemporary medicine, with good reason. Doctors used leeches to let blood and hot plasters to bring on blisters, which were then drained. In 1790, Hahnemann developed a fever that transformed his career. After swallowing powder from the bark of a cinchona tree, he saw his body temperature rise. Cinchona bark contains quinine, which was already known to treat malaria. Hahnemann considered the facts: cinchona seemed to give him a fever; fever is a symptom of malaria; and cinchona treats malaria. He then made an acrobatic leap of logic: medicines bring on the same symptoms in healthy people as they cure in sick ones. Find a substance that induces a symptom and it might be used to treat that symptom in another."
(...)
"One common designation is “NC”, where C signifies that a substance is diluted by a ratio of 1:100 and N stands for the number of times the substance has been diluted. So a dilution of 200C would mean that one gram of a substance had been diluted within 100 grams of water, with the process repeated 200 times. At this dilution not a single molecule of the original substance remains when the water is used to make pills; most homeopathic pills thus consist entirely of sugar. However, the water and the pills are supposed to retain a “memory” of the original substance.

This is nonsense. Studying homeopathy is difficult, points out the world’s biggest funder of medical research, the US National Institutes of Health (NIH), because it is hard to examine the effects of a medicine when that medicine has little or no active ingredient. Researchers can neither confirm that the medicine contains what it claims to nor show the chemical effect of the diluted medicine within the body. "
(...)
"The most comprehensive review of homeopathy was published in 2005 in the renowned medical journal The Lancet. Researchers compared trials of homeopathic and conventional medicines. In the bigger, well-designed trials, there was “no convincing evidence” that homeopathy was more effective than a placebo, they found. "

Privação do sono e impacto nos genes

http://www.bbc.com/news/health-21572686

Citação:
"So researchers [2013] at the University of Surrey analysed the blood of 26 people after they had had plenty of sleep, up to 10 hours each night for a week, and compared the results with samples after a week of fewer than six hours a night.

More than 700 genes were altered by the shift. Each contains the instructions for building a protein, so those that became more active produced more proteins - changing the chemistry of the body.

Meanwhile the natural body clock was disturbed - some genes naturally wax and wane in activity through the day, but this effect was dulled by sleep deprivation.

Prof Colin Smith, from the University of Surrey, told the BBC: "There was quite a dramatic change in activity in many different kinds of genes."

Areas such as the immune system and how the body responds to damage and stress were affected.

Prof Smith added: "Clearly sleep is critical to rebuilding the body and maintaining a functional state, all kinds of damage appear to occur - hinting at what may lead to ill health.

"If we can't actually replenish and replace new cells, then that's going to lead to degenerative diseases.""

"The study's authors concluded: "Studies have shown that chronic jet lag and rotating shift work can increase an individual's risk of developing hypertension, obesity, and other metabolic disorders.

"Our results identify vasopressin signalling as a possible therapeutic target for the management of circadian rhythm [body clock] misalignment.""

Estudo analisa padrões de sono por país

"(...) told the BBC: "I think it's interesting; there's been a trend for these studies using data from twitter and apps and finding interesting correlations across the world we've never been able to do by putting people in sleep lab.

"It highlights that although our body clocks are programming us to do certain things, we can't as we're ruled by social circumstances.

"We won't know the long-term consequences of this for many years."

Disrupted sleep in shift workers has been linked to a range of health problems, including type 2 diabetes.

Dr Reddy said the next wave of studies would gather data from activity and sleep monitors and "that's where the future of this is"."

Estudo tenta relacionar passos dados com obesidade

Citando:
"The key ingredient was "activity inequality" - it's like wealth inequality, except instead of the difference between rich and poor, it's the difference between the fittest and laziest.

The bigger the activity inequality, the higher the rates of obesity.

Tim Althoff, one of the researchers, said: "For instance, Sweden had one of the smallest gaps between activity rich and activity poor... it also had one of the lowest rates of obesity."

The United States and Mexico both have similar average steps, but the US has higher activity inequality and obesity levels."

"Sentido de vida" importante para qualidade do sono?

O NHS Choices analisa as notícias e diz que pode não ter a ver com o sentido de vida propriamente, ou seja a notícia é algo enganosa:
http://www.nhs.uk/news/2017/07July/Pages/Does-having-a-sense-of-purpose-in-life-help-you-sleep-better.aspx

Citando:
""Sense of purpose aids sleep, US scientists find," The Guardian reports on a new study that explored the relationship between having a sense of purpose in life and quality of sleep in older adults.

The study analysed data from 800 older adults with an average age of 80 in the US.

Researchers found that generally, having a greater sense of purpose in life was associated with better quality of sleep, as well as a decreased likelihood of sleep disorders such as sleep apnoea and restless leg syndrome. "
