20 Minute Contact with Nature Reduces Stress Hormone Cortisol






The data revealed that just a twenty-minute nature experience was enough to significantly reduce cortisol levels. But if you spent a little more time immersed in a nature experience, 20 to 30 minutes sitting or walking, cortisol levels dropped at their greatest rate. After that, additional de-stressing benefits continue to add up but at a slower rate. The image is in the public domain.

Novo estudo questiona: será que devemos substituir antidepressivos por exercícios físicos?








Um novo estudo sugere que os exercícios físicos são tão eficazes em aliviar os sintomas de problemas de saúde mental e transtornos de humor, como ansiedade, depressão e esquizofrenia, quanto os medicamentos tradicionais. Se confirmada, essa pode ser uma excelente notícia para pacientes que sofrem com este tipo de problema, uma vez que isso pode significar menos tempo em instalações psiquiátrica e menos probabilidade de dependência de medicamentos psicotrópicos.

Play equipment that gets kids moving

Parents will be pleased to know that more is not always better when it comes to play equipment for their children.

A study by researchers at The University of Queensland found children who have access to fixed play equipment like swings and slides and fewer electronic devices were more likely to meet national physical activity guidelines.

UQ School of Public Health researcher Dr Katrina Moss said it was good news for parents, who can implement the findings at home.

“In this study, we found the type of play equipment that children have at home is directly related to the amount of physical activity they do,” Dr Moss said.

“This is good news because play equipment at home is modifiable, and in lots of cases, it can be easily changed.

Como o exercício – em especial o treino intervalado – ajuda a mitocôndria a afastar o envelhecimento







É frequentemente repetido, mas é verdade: o exercício mantém você saudável. Ele aumenta o seu sistema imunológico, mantém a mente afiada, ajuda a dormir, mantém o seu tônus ​​muscular e estende a sua vida saudável. Pesquisadores há muito suspeitam que os benefícios do exercício se estendem até o nível celular, mas sabem relativamente pouco sobre quais exercícios ajudam as células a reconstruir organelas-chaves que se deterioram com o envelhecimento. Um estudo publicado em 7 de março em Cell Metabolism descobriu que o exercício – e em particular o treinamento intervalado aeróbico de alta intensidade, como ciclismo e caminhada – impulsiona células a produzirem mais proteínas para suas mitocôndrias (produtoras de energia) e seus ribossomos (produtores de proteínas), efetivamente parando o envelhecimento no nível celular.

Regular exercise is good for your heart, no matter how old you are!

Regular exercise is highly beneficial for all patients with cardiovascular disease regardless of age, report investigators in the Canadian Journal of Cardiology, published by Elsevier. Their results showed that the patients who benefited most from cardiac rehabilitation were those who started out with the greatest physical impairment.

Elderly patients are at a higher risk for complications and accelerated physical deconditioning after a cardiovascular event, yet older patients are largely underrepresented in rehabilitation programs. Studies have shown that this might be due to a lack of referral and encouragement to attend cardiac rehabilitation in older patients.

“Aging is associated with several factors such as increased inflammation or oxidative stress that predispose people to cardiovascular diseases. As a result, elderly patients are usually less fit than their younger counterparts, and deconditioning is accelerated once cardiovascular disease is established,” explained lead investigator Gaëlle Deley, PhD, INSERM UMR1093 — CAPS, Faculty of Sports Sciences, University of Burgundy Franche-Comté, Dijon, France. “However, there are few data about the impact of patient age on the physical and psychological effectiveness of cardiac rehabilitation.”

Several studies have looked at the effects of cardiac rehabilitation in older adults. However, these data often focus on patients above the age of 65 with no distinction between old and very old patients and examine either physical or psychological outcomes but not both.
