EXERCISE MORE – 7 MINUTES MIGHT BE ENOUGH
You might have seen some talk recently about the scientific 7 minute workout mentioned in The New York Times. So if you thought exercise was something you didn’t have time for, maybe you can fit it in after all.
Exercise has such a profound effect on our happiness and well-being that it’s actually been proven to be an effective strategy for overcoming depression. In a study cited in Shawn Achor’s book, The Happiness Advantage, three groups of patients treated their depression with exercise. The results of this study really surprised me. Although all three groups experienced similar improvements in their happiness levels to begin with, the follow up assessments proved to be radically different:
The groups were then tested six months later to assess their relapse rate. Of those who had taken the medication alone, 38 percent had slipped back into depression. Those in the combination group were doing only slightly better, with a 31 percent relapse rate. The biggest shock, though, came from the exercise group: Their relapse rate was only 9 percent!
You don’t have to be depressed to gain benefit from exercise, though. It can help you to relax, increase your brain power and even improve your body image, even if you don’t lose any weight.
A study in the Journal of Health Psychology found that people who exercised felt better about their bodies, even when they saw no physical changes:
Body weight, shape and body image were assessed in 16 males and 18 females before and after both 6 × 40 mins exercise and 6 × 40 mins reading. Over both conditions, body weight and shape did not change. Various aspects of body image, however, improved after exercise compared to before.
We’ve explored exercise in depth before, and looked at what it does to our brains, such as releasing proteins and endorphins that make us feel happier, as you can see in the image below.
SLEEP MORE – YOU’LL BE LESS SENSITIVE TO NEGATIVE EMOTIONS
We know that sleep helps our bodies to recover from the day and repair themselves, and that it helps us focus and be more productive. It turns out, it’s also important for our happiness.
In NutureShock, Po Bronson and Ashley Merryman explain how sleep affects our positivity:
Negative stimuli get processed by the amygdala; positive or neutral memories gets processed by the hippocampus. Sleep deprivation hits the hippocampus harder than the amygdala. The result is that sleep-deprived people fail to recall pleasant memories, yet recall gloomy memories just fine.
In one experiment by Walker, sleep-deprived college students tried to memorize a list of words. They could remember 81% of the words with a negative connotation, like “cancer.” But they could remember only 31% of the words with a positive or neutral connotation, like “sunshine” or “basket.”
The BPS Research Digest explores another study that proves sleep affects our sensitivity to negative emotions. Using a facial recognition task over the course of a day, the researchers studied how sensitive participants were to positive and negative emotions. Those who worked through the afternoon without taking a nap became more sensitive late in the day to negative emotions like fear and anger.
Using a face recognition task, here we demonstrate an amplified reactivity to anger and fear emotions across the day, without sleep. However, an intervening nap blocked and even reversed this negative emotional reactivity to anger and fear while conversely enhancing ratings of positive (happy) expressions.
Of course, how well (and how long) you sleep will probably affect how you feel when you wake up, which can make a difference to your whole day. Especially this graph showing how your brain activity decreases is a great insight about how important enough sleep is for productivity and happiness:
Another study tested how employees’ moods when they started work in the morning affected their work day.
Researchers found that employees’ moods when they clocked in tended to affect how they felt the rest of the day. Early mood was linked to their perceptions of customers and to how they reacted to customers’ moods.
And most importantly to managers, employee mood had a clear impact on performance, including both how much work employees did and how well they did it.
Sleep is another topic we’ve looked into before, exploring how much sleep we really need to be productive.
HELP OTHERS – 100 HOURS A YEAR IS THE MAGICAL NUMBER
One of the most counterintuitive pieces of advice I found is that to make yourself feel happier, you should help others. In fact, 100 hours per year (or two hours per week) is the optimal time we should dedicate to helping others in order to enrich our lives.
If we go back to Shawn Achor’s book again, he says this about helping others:
…when researchers interviewed more than 150 people about their recent purchases, they found that money spent on activities—such as concerts and group dinners out—brought far more pleasure than material purchases like shoes, televisions, or expensive watches. Spending money on other people, called “prosocial spending,” also boosts happiness.
The Journal of Happiness Studies published a study that explored this very topic:
Participants recalled a previous purchase made for either themselves or someone else and then reported their happiness. Afterward, participants chose whether to spend a monetary windfall on themselves or someone else. Participants assigned to recall a purchase made for someone else reported feeling significantly happier immediately after this recollection; most importantly, the happier participants felt, the more likely they were to choose to spend a windfall on someone else in the near future.
So spending money on other people makes us happier than buying stuff for ourselves. What about spending our time on other people? A study of volunteering in Germany explored how volunteers were affected when their opportunities to help others were taken away:
Shortly after the fall of the Berlin Wall but before the German reunion, the first wave of data of the GSOEP was collected in East Germany. Volunteering was still widespread. Due to the shock of the reunion, a large portion of the infrastructure of volunteering (e.g. sports clubs associated with firms) collapsed and people randomly lost their opportunities for volunteering. Based on a comparison of the change in subjective well-being of these people and of people from the control group who had no change in their volunteer status, the hypothesis is supported that volunteering is rewarding in terms of higher life satisfaction.
In his book Flourish: A Visionary New Understanding of Happiness and Well-being, University of Pennsylvania professor Martin Seligman explains that helping others can improve our own lives:
…we scientists have found that doing a kindness produces the single most reliable momentary increase in well-being of any exercise we have tested.
PRACTICE SMILING – IT CAN ALLEVIATE PAIN
Smiling itself can make us feel better, but it’s more effective when we back it up with positive thoughts, according to this study:
A new study led by a Michigan State University business scholar suggests customer-service workers who fake smile throughout the day worsen their mood and withdraw from work, affecting productivity. But workers who smile as a result of cultivating positive thoughts – such as a tropical vacation or a child’s recital – improve their mood and withdraw less.
Of course it’s important to practice “real smiles” where you use your eye sockets. It’s very easy to spot the difference:
According to PsyBlog, smiling can improve our attention and help us perform better on cognitive tasks:
Smiling makes us feel good which also increases our attentional flexibility and our ability to think holistically. When this idea was tested by Johnson et al. (2010), the results showed that participants who smiled performed better on attentional tasks which required seeing the whole forest rather than just the trees.
A smile is also a good way to alleviate some of the pain we feel in troubling circumstances:
Smiling is one way to reduce the distress caused by an upsetting situation. Psychologists call this the facial feedback hypothesis. Even forcing a smile when we don’t feel like it is enough to lift our mood slightly (this is one example of embodied cognition).
One of our previous posts goes into even more detail about the science of smiling.
MEDITATE – REWIRE YOUR BRAIN FOR HAPPINESS
Meditation is often touted as an important habit for improving focus, clarity and attention p, as well as helping to keep you calm. It turns out it’s also useful for improving your happiness:
In one study, a research team from Massachusetts General Hospital looked at the brain scans of 16 people before and after they participated in an eight-week course in mindfulness meditation. The study, published in the January issue of Psychiatry Research: Neuroimaging, concluded that after completing the course, parts of the participants’ brains associated with compassion and self-awareness grew, and parts associated with stress shrank.
Meditation literally clears your mind and calms you down, it’s been often proven to be the single most effective way to live a happier live. I believe that this graphic explains it the best:
According to Shawn Achor, meditation can actually make you happier long-term:
Studies show that in the minutes right after meditating, we experience feelings of calm and contentment, as well as heightened awareness and empathy. And, research even shows that regular meditation can permanently rewire the brain to raise levels of happiness.
The fact that we can actually alter our brain structure through mediation is most surprising to me and somewhat reassuring that however we feel and think today isn’t permanent.
PRACTICE GRATITUDE – INCREASE BOTH HAPPINESS AND LIFE SATISFACTION
This is a seemingly simple strategy, but I’ve personally found it to make a huge difference to my outlook. There are lots of ways to practice gratitude, from keeping a journal of things you’re grateful for, sharing three good things that happen each day with a friend or your partner, and going out of your way to show gratitude when others help you.
In an experiment where some participants took note of things they were grateful for each day, their moods were improved just from this simple practice:
The gratitude-outlook groups exhibited heightened well-being across several, though not all, of the outcome measures across the 3 studies, relative to the comparison groups. The effect on positive affect appeared to be the most robust finding. Results suggest that a conscious focus on blessings may have emotional and interpersonal benefits.
The Journal of Happiness studies published a study that used letters of gratitude to test how being grateful can affect our levels of happiness:
Participants included 219 men and women who wrote three letters of gratitude over a 3 week period.
Results indicated that writing letters of gratitude increased participants’ happiness and life satisfaction, while decreasing depressive symptoms.
Quick last fact: Getting older will make yourself happier
As a final point, it’s interesting to note that as we get older, particularly past middle age, we tend to grow happier naturally. There’s still some debate over why this happens, but scientists have got a few ideas:
Researchers, including the authors, have found that older people shown pictures of faces or situations tend to focus on and remember the happier ones more and the negative ones less.
Other studies have discovered that as people age, they seek out situations that will lift their moods — for instance, pruning social circles of friends or acquaintances who might bring them down. Still other work finds that older adults learn to let go of loss and disappointment over unachieved goals, and hew their goals toward greater wellbeing.
So if you thought being old would make you miserable, rest assured that it’s likely you’ll develop a more positive outlook than you probably have now.
