Hot People are More Likely to be Depressed

There’s a popular theory that hot people have it easier in life, and that might be true for looks but not for temperature. People were asked to self report their levels of depression and it turns out that there’s a correlation between their body temperature and mood. The results revealed that people with higher body temperatures were more likely to be depressed. This connection can help researchers better understand depression and how we can treat it better.

The study data showed that as self-reported depression symptoms became more severe, body temperature averages got higher. There was also some association between higher depression scores and lower daily temperature fluctuations, but not to a statistically significant level.

With around 5 percent of people around the world thought to be living with depression, efforts to understand and effectively treat it are now more urgent than ever. Each new discovery brings more hope in tackling the problem.

Rural and Urban Areas Have Less Depression

Where you live matters in almost every way imaginable, and there’s now more evidence that your location impacts your mental health. We now know that what has been colloquially known is now provably true: rates of depression are higher in suburban communities than elsewhere. Of course, you’re probably thinking that the rural lifestyle is that one that provides the best mental health, but what you probably don’t realize that urban living is also really good for you. So if you’re living in an in between sub-urban and sub-rural area and not feeling great than maybe you should move out the country or in to the city.

We think the relative higher risks of depression found in sprawling, low-rise suburbs may be partly down to long car commutes, less public open space and not high enough resident density to enable many local commercial places where people can gather together, such as shops, cafes and restaurants. But of course, there may be many other factors, too.

This doesn’t mean there aren’t potential benefits to living in the suburbs. Some people may in fact prefer privacy, silence and having their own garden. 

We hope that this study can be used as a basis for urban planning. The study provides no support for the continued expansion of car-dependent, suburban single-family housing areas if planners want to mitigate mental health issues and climate change.

Lift the Weight of Depression by Lifting Weights

Any physical movement is good for you and the evidence keeps piling up. A meta-analysis of the relationship between resistance exercise training (RET) and depression concludes that lifting weights does indeed help your mental health. Because studies usually look at only aspect of mental health we need more research looking across studies to provide a solid foundation and that’s what we’re seeing here.

One thing I realized when going to the gym is that it took weeks to get that positive feeling from working out. Don’t expect instance levity in your mood or skills. There’s no reason to start at the extreme by lifting way more than you can. Start with lighter weights and slowly work your way up to whatever you like.

After reviewing the literature, Gordon and team found that regardless of age, sex, or health status, RET is “associated with a significant reduction in depressive symptoms.” The largest gains were found in adults with elevated symptoms, which gave the researchers hope that RET “may be particularly helpful for reducing depression symptoms in people with greater depressive symptoms.” They also found that supervised workout sessions resulted in larger gains than in unsupervised sessions.

As Gordon says, it’s impossible to blind people for this sort of research—you know who is lifting weights and who is not. As with most studies, the placebo effect could be at work. But given all we know about the benefits of exercise, this is a placebo with few side effects (overexertion and muscle strains being the most prominent). The benefits outweigh any potential risk.

Volunteering Improves Your Mental Health

Volunteering is good for others, and it’s good for the volunteers too. People all have difference reasons for volunteering in their communities and whatever motivates them clearly helps others too. What’s really interesting is that it turns out that volunteers are rewarded by better mental health. Yes, volunteering can help people deal with depression and provide a clearer purpose in life.

It’s generally understood that helping out others makes a person feel nice, but that experience goes beyond just the feel-good glow of altruism. Studies have found that helping others has tangible benefits, both mental and physical, from lowering your blood pressure to reducing feelings of depression. And research hasn’t found any significant difference in the types of volunteering—any kind of helpful act can create benefits.

“Research has shown that there’s evidence volunteer work promotes that psychological well being you’re talking about,” Rodlescia Sneed, a public health research associate at Michigan State University who has studied the impacts of volunteering. “In my own work I’ve shown it’s linked to improvements in factors like depressive symptoms, purpose in life, and feelings of optimism.”

Local Greenbelts can Reduce Depression and Obesity

Living near green space will make your life better. New studies coming out of Europe point out that proximity to nature has an impact on levels of depression, as in there is less depression. If you have the option to keep local forests (or any green space) then you should keep it! Not only are nature areas good for the mind, they’re also good for the body. The same research has pointed out that obesity rates are lower in places where nature is accessible.

The benefits aren’t just for individuals because fitter, happier people is better for society at large.

Overall, nature is an under-recognised healer, the paper says, offering multiple health benefits from allergy reductions to increases in self-esteem and mental wellbeing.

A study team of 11 researchers at the Institute for European environmental policy (IEEP) spent a year reviewing more than 200 academic studies for the report, which is the most wide-ranging probe yet into the dynamics of health, nature and wellbeing.

The report makes use of several studies that depict access to nature as being inextricably linked to wealth inequality, because deprived communities typically have fewer natural environments within easy reach.
