Exercise for your body and mind

Most of us should exercise more, and most of us know that. More exercise would be good for our health – but also improves our mental health dramatically.

The general recommendation is that we should exercise for 150 min per week. That’s not so bad – sounds like with half an hour a day, we might be fine. We can even break this up into 10 minute intervals and still get the same benefits. Kids and teens should move more, for them the recommendation is 60 minutes of intensive aerobic a day, at least 3 times a week.

 

Are you an active couch potato?

However, if we work out for half an hour per day and then sit for the rest of it, the benefits of the exercise does not outweigh the negative effects of the sitting. On average, adults only exercise 1 % of their day and sit for more than 8 hours! Unfortunately, the adverse health effects of sedentary behavior is independent of leisure time exercise. Only if you exercise more than 1 hour a day, and that means a moderate to intense work out – not just going for a walk – only then can you counteract the increased mortality rates due to chronic sitting. So, other physical activity is needed in addition to the planned training session at the gym during your lunch break.

Now, what are these adverse health effects of sitting? Most of us know that too much inactivity has negative consequences for the cardiovascular system; many have probably heard that also the risk for other diseases like cancer may be reduced by working out more. Lesser known is the relationship between sitting around too much and mental health problems.

 

Too much sitting can make you feel depressed

The risk for depression is increased by 15% for people who don’t move enough. This in turn relates back to increased mortality rates: people with depression die 8-10 years earlier (which is mostly due to somatic comorbidities). Of course, this is a catch-22: when you feel depressed, it is especially hard for you to motivate to work out.

One study was even able to show, that there is a causal link between sitting too much and depression: participants in this study were asked to sit for just additional 30 minutes per day – and these people showed an increase in their negative mood as well as greater stress induced inflammation.

The threshold for too much sitting seems to lie somewhere around the 6 hours per day. People who work eight-hour jobs might run into problems. Maybe you can ask for a standing desk or get yourself a yoga ball to sit on. It is also highly recommended to break up long periods of sitting. Take extra walks to the coffee room, the bathroom or the copy machine.

Exercise can even prevent future depression, as some prospective studies were able to show. One of them even claims that 12% of future episodes of depression are preventable with only 1 hour exercise per week!

One recent meta analysis  showed that exercise was as effective as psychological therapy and pharmacological treatment! The intensity of the work out didn’t matter, but the frequency did. Aerobic and resistance training both seem to be effective; the best results were found for a combination of both kinds of workouts.

If you feel motivated to start working out more after reading this blog post, take your training level into account. Don’t jump into a highly strenuous exercise program right away, because it will be a lot harder for you to stick with it. If you feel a lot of pain right after you worked out, you will start connecting exercise with feeling bad. Therefore, it will be harder and harder for you to get going again. If you start with a very light work out and increase it slowly, you can condition yourself to connect exercise with feeling good afterwards.

Whatever you choose to do, if you lift weights, run, do Yoga or even just go for brisk walk – as long as you get moving, you will feel happier!

How to recover from stressful life events

(and a little bit on dealing with grief)

We have been writing a lot about how to deal with stress. But let’s face it: everybody will go through phases in their life where they experience intense stress. Even if you are highly resilient and an experienced yogi knowing all the breathing techniques – there are things that won’t leave you unscathed.

We have been through some tough times ourselves and know from personal experience that such times will affect you – not just emotionally, but on the physical and cognitive levels as well. We become tired, more easily irritable, our fitness level decreases. We feel mentally and physically exhausted. In addition, we struggle with everything that has a higher cognitive demand. It becomes harder to focus, harder to engage and our short-term memory is affected.

My (Rebecca’s, it’s me writing today) most intense stress experience comes from my student years, when I just started my advanced master’s courses in neural and behavioral science. At that time, my mum was terminally ill.

My mum and me, probably 25 years ago

First, I struggled with finding a balance between spending time with her, but still living the student life and fulfilling all the very ambitious course work at university. Then she died – and even though I knew it was coming, I felt completely unprepared. I managed to finish my master’s degree, even with good grades, but emotionally, I was a mess. My mum was my best and closest friend. We used to talk every day and about everything. At that point of my life, I was at a deep loss.

 

It took me several years to recover from this experience.

During these years, I noticed something strange: I could not really remember events from the months before her death. Everything seemed blurry. I mixed up names and people, did not remember where I knew them from, and even forgot important things that had happened. The time before my mum’s death, the most stressful time, disappeared in a cloud within my head.

I was studying neuroscience and soon learned that the hippocampus is affected by intense or chronic stress. Just recently, a large meta-analysis with over 800 participants with PTSD (post-traumatic stress disorder) confirmed, that the hippocampus decreases in size when subjected to highly stressful events.

How did I recover?

First of all, the best medicine is time. Traumatic events need time to be processed. Usually it takes longer than our social environment believes we need and is willing to give us. In the case of losing a close one, there is even a prescribed “normal” time window after which we are supposed to function normal again. In the diagnostic manual for psychiatric disorders, the time defined as normal, non-pathological grief has decreased dramatically over the last years. In the DSM version number 3, it was one year, in number 4 it was two months, in the newest edition number 5, there were rumors it would be reduced to only two weeks (I guess that was too drastic and didn’t happen).

For all stressful events, from an especially hard time at work over heartbreak to losing a loved one, it is important to be patient with ourselves and accept that it might take a while until we “get over it”. Often, we feel fine for a while, and then something triggers the memory of the stressful event or phase and we have to go through another time period of processing it. Be patient with yourself. Don’t get annoyed, if your brain makes you go through it again.

This is actually a fascinating mechanism: our brain gives us a break from processing the stressful life-event for a while. When we have become stable again, it will allow the memories to come back up. The brain uses the calmer times to process difficult experiences. Accept this and see it as a positive process: every time this happens, it is getting easier.

 

What else can we do to recover from stress?

First, stabilize your basis. Make sure, you are exercising, eating well and sleeping enough. After my mum’s death, I started exercising multiple times a week and eating more healthy food. Not really to combat the stress, but to deal with anxiety regarding my own health. However, it did have a positive effect. Especially the regular exercise felt extremely good. When we are stressed, our body prepares for something bad to happen. Stress is an adaptive mechanism to protect us. Our body prepares for the fight-or-flight reaction. So we should use it in that way it was meant to be: go for long runs or an intense sports class. That way, stress hormones fulfill their biological function and are less harmful than when we are sitting on the couch with our 100+ heartrate. People who exercise are reportedly more resilient to stress, which also means they recover faster from it.

Again, meditation becomes an extremely helpful tool during stress recovery. 

However, if you have not practiced meditation before, it might be the wrong time to learn it. If you are still in the stressful phase, it will be hard for you to sit down and calm your mind. Better to train meditation during a calmer time of your life to have this great tool ready, when you need it. If you are currently recovering from stress, don’t feel discouraged to try it out! But don’t beat yourself up – or the method – if it does not have the effect you were looking for. Try to exercise instead and come back to meditation practice when you are further in your recovery journey.

Some other tips:

Try a new hobby like painting or pottery. Start writing or dancing. Choose whichever form of art you are most drawn to and get lost in it for a few hours per week.

Listen to classical music. It has been shown to help your cardiovascular system during stress recovery.

Treat yourself with immersive and positive nature experiences, which can reinforce your recovery process.

The power of reappraisal

In our previous post, we talked about how re-appraisal of stress can affect your health. It is some kind of self-fulfilling prophecy: if you believe that stress is bad for you, it will have more negative health consequences.

 

Make the strategy of reappraisal or re-evaluation your close friend – not only when it comes to stress.

This will help you in many other areas of life. You might have ideas and concepts anchored in your mind that are not accurate. For example, you might be sure, that you are quite a lazy person. This idea could have been planted there already in your childhood, when you parents called you lazy because you didn’t want to clean your room. It was probably reinforced during your teenager years, since teenagers usually have other priorities than working hard in school, and are being called lazy on a regular basis. Maybe you got back on track, when you started working or studying – but the concept of your character already contained the description “lazy”.

 

Self-concept reappraisal

Now, this is where the problem lies: we think of ourselves as a quite clearly defined entity with certain traits. We believe, we know ourselves, that we can predict how we will react in specific scenarios and – most importantly – that we won’t or will hardly change.

However, we do not base our self-concept entirely on extensive reflection and detailed observations of our own behavior. We might use these tools, but our self-concept will always be integrating the views, thoughts and comments that others make about us. If you kept hearing that you are a lazy person, you might have decided to prove them all wrong, but more likely, you accepted this description into your idea about who you are.

As a consequence, the word lazy pops up, whenever you do not feel like doing a task. You will say to yourself: “I just can’t help it. I am a lazy person.” It is the best excuse that you can come up with, because it sounds so definite and fits perfectly into the narrative that you repeat. If you simply are a lazy person, how could you ever change that?

 

A simple strategy for reappraisal

This is where re-appraisal comes into play: As soon as you hear your inner voice uttering such a sentence, think about the description.

Are you really lazy, low-energy, anti-social, a loner, difficult, etc.? Start by writing down all these descriptors that you give yourself. Make a little list over a couple of days. Then, try to find evidence in the past as well as in the present. Were you really a lazy child or did you simply not like cleaning your room, but were active in sports and engaged in school? Were you really a lazy teenager or did you just invest your energy in writing sad song, trying to master a cool skateboard trick or doing everything to impress your crush? Now as an adult, are you really lazy or are there good reason why you want to avoid a certain task? Are there concrete reasons, that are not based in a negative trait you are assigning yourself?

 

Watch out for these pitfalls

When doing this little exercise, avoid the trap of generalization. Just because you might be lazy, when it comes to doing the dishes, does not make you a lazy person. You might invest a lot of energy into gardening, or cooking or your job.

Also, notice patterns of disqualifying all the evidence that speaks against your theory about who you are. For example, a childhood memory of you setting the dinner table might come up, and you brush it away thinking “That was just a one-time-thing. Usually, I was indeed lazy.”

 

Last, but not least: You can change!

If all the past and present evidence shows that you are a super lazy couch potato, but you want to change that: go ahead. Our character is not set in stone. Our brain stays flexible until old age.

That notion that “we develop our personality until we are 15 and then we are who we are” is completely incorrect. The brain can not form news neurons (except for in the hippocampus), but it constantly alters the connections between existing neurons. That way it stays adaptable – and so are you.

If you want to become a more energetic and active person, do it! Start by changing how you describe yourself. When you catch your inner voice talking about how lazy and always tired you are, talk back to it. Remind yourself of examples, when you are full of energy. Soon you won’t just become more active, but your self-esteem will increase drastically, when you start cutting out all the negative and inaccurate descriptors. Don’t let self-directed negativity hold you back!
