30 Minutes in Your Local Park is Perfect

- Adam Clare


Urban parks are great and now some Aussie researchers have found another reason to create more of them: it’s really good for your health. We’ve known for years that spending time in nature is good for people but his research augments that knowledge with a timeframe. It takes only 30 minutes of being in an a park to see benefits to one’s health. Which means that you can get enough nature on your lunch break (you should get more though).

“If everyone visited their local parks for half an hour each week there would be seven per cent fewer cases of depression and nine percent fewer cases of high blood pressure,” she said.

“Given that the societal costs of depression alone in Australia are estimated at $A12.6 billion a year, savings to public health budgets across all health outcomes could be immense,” she said.

UQ CEED researcher Associate Professor Richard Fuller said the research could transform the way people viewed urban parks.

“We’ve known for a long time that visiting parks is good for our health, but we are now beginning to establish exactly how much time we need to spend in parks to gain these benefits,” he said.

And over at Reddit a user posted a good summary on why nature is good for you:

It’s probably a combination of things. Sunlight allows the body to produce vitamin D, which has been linked with a reduction in depressive symptoms.

When you’re in a park you’re likely walking and doing physical activities, and exercise is positively correlated with improvements in mood and reduced depressive symptoms, not to mention it’s good for the heart, blood pressure, and physical health in general.

Smart Kids, Depression, Existential Crisis, And What You Can Do

- Adam Clare

Kids think a lot about the world around them thanks to their natural curiosity. As adults we can embrace their curiosity and encourage it or we can dull their intellectual indulgences. How we react and support kids in their process of learning can have a big impact.

At various ages kids learn that their lives are finite and this can lead to what is referred to existential depression. They ask fundamental questions about life and what one ought to do while alive (something that many adults only do when they reach their midlife crises). Denying proper answers to kids who are questioning the meaning of life can cause more harm than good. So when confronted by the “big” questions of life don’t discourage the line of inquiry, instead you ought to embrace the discussion.

How can we help our bright youngsters cope with these questions? We cannot do much about the finiteness of our existence. However, we can help youngsters learn to feel that they are understood and not so alone and that there are ways to manage their freedom and their sense of isolation.

The isolation is helped to a degree by simply communicating to the youngster that someone else understands the issues that he/she is grappling with. Even though your experience is not exactly the same as mine, I feel far less alone if I know that you have had experiences that are reasonably similar. This is why relationships are so extremely important in the long-term adjustment of gifted children (Webb, Meckstroth and Tolan, 1982).

Using Ketamine to Treat Severe Depression

- Adam Clare 1 Comment

Depression affects a lot of people and research into dealing with depression has taken on a lot of forms over the years. Recently there has been growing use of “party drugs” to treat those with depression. People with severe depression don’t react to treatments the same as others, which has led researchers to look for more diverse options.

Ketamine, used in veterinary clinics and in hospitals, has been used to treat depression and the results are rather impressive – 75% of people treated with ketamine showed positive results!

Since 2006, dozens of studies have reported that it can also reverse the kind of severe depression that traditional antidepressants often don’t touch. The momentum behind the drug has now reached the American Psychiatric Association, which, according to members of a ketamine task force, seems headed toward a tacit endorsement of the drug for treatment-resistant depression.

Experts are calling it the most significant advance in mental health in more than half a century. They point to studies showing ketamine not only produces a rapid and robust antidepressant effect; it also puts a quick end to suicidal thinking.

A New Perspective on Depression

- Adam Clare

Depression seemed to be talked about more last year than in previous years thanks to celebrities revealing their troubles with the affliction. There’s also been more research into depression. With more people thinking about and looking into depression we get new perspectives on the issue.

Now, some researchers are arguing that depression could be a symptom of lifestyle decisions and some influence from our evolution. The evolution aspect is rather interesting because it could be interpreted that depression is a reaction to help one person not infect others with communicable diseases.

So if people with depression show classic sickness behaviour and sick people feel a lot like people with depression – might there be a common cause that accounts for both?

The answer to that seems to be yes, and the best candidate so far is inflammation – a part of the immune system that acts as a burglar alarm to close wounds and call other parts of the immune system into action. A family of proteins called cytokines sets off inflammation in the body, and switches the brain into sickness mode.

Both cytokines and inflammation have been shown to rocket during depressive episodes, and – in people with bipolar – to drop off in periods of remission. Healthy people can also be temporarily put into a depressed, anxious state when given a vaccine that causes a spike in inflammation. Brain imaging studies of people injected with a typhoid vaccine found that this might be down to changes in the parts of the brain that process reward and punishment.

Even Moderate Exercise Can Stave Off Depression

- Adam Clare

There’s a bunch of scientific evidence that already proves the benefits of exercise for one’s mental health, and now we know that even moderate workouts can have a huge impact. Even walking for just 20-30 minutes a day can improve resilience to depression!

So if you don’t want to go to the gym or lace up for a run then don’t – just go for a short walk.

This is the first longitudinal review to focus exclusively on the role that exercise plays in maintaining good mental health and preventing the onset of depression later in life.

Mammen—who is supervised by Professor Guy Faulkner, a co-author of the review— analyzed over 26 years’ worth of research findings to discover that even low levels of physical activity (walking and gardening for 20-30 minutes a day) can ward off depression in people of all age groups.

Mammen’s findings come at a time when mental health experts want to expand their approach beyond treating depression with costly prescription medication. “We need a prevention strategy now more than ever,” he says. “Our health system is taxed. We need to shift focus and look for ways to fend off depression from the start.”
