It is 8:00 am, pre-coffee (if that’s your thing), and you’re getting ready to walk out the door after a night of staying up with your sick spouse, child, or roommate. You’re starting to feel super-human, juggling all your pre-work morning responsibilities with a heavy head and groggy eyes, when your spouse/child/roommate walks up to you and asks an innocent question: “I’m hungry. What are we having for breakfast?” You look at their cheerful face and take instant offense. You think, “What do you mean, what’s for breakfast? Can’t you see I’m simultaneously feeding the dog, prepping the beans for tonight’s slow-cooker dinner, and reading Junior’s school newsletter?” According to a new U.C. Berkeley study published in the Journal of Neuroscience earlier this week, there is a strong link between a lack of quality sleep and decreased ability to distinguish between positive and negative emotional facial expressions in others. Researchers viewed brain scans and monitored the heart rates of 18 adult participants while they randomly viewed 70 images of faces with random expressions: positive, neutral, and negative emotions. Each individual viewed the facial images twice, once when they were fully rested and once after they had been awake for 24 consecutive hours. The study noted a neural link between the quality and amount of sleep a person gets and his or her ability to correctly process others’ facial expressions. The results of the study inferred that there is “a role for REM sleep in affective brain recalibration” and “the next-day success of emotional discrimination…” All the more reason to get a good night’s sleep! For more information on the study, you can refer to the following articles: http://news.berkeley.edu/2015/07/14/brain-facialexpressions/ http://www.huffingtonpost.com/2015/07/15/sleep-brain-emotions_n_7801726.html
There are all kinds of benefits from getting a good nights sleep. It can help us live longer, lower the risks of having a stroke or heart disease, or even spur our minds to be more creative.
But what about memory?
Shai Marcu teamed up with TED-Ed to make a video that sheds light on the mistaken idea that sleep is lost time or just a way to rest when all our work is done.
Many people feel that they get a better night’s sleep after a day of physical activity. It makes sense: The more active you are during the day, the easier it may be for you to relax and fall asleep at night. Interestingly enough, sleep may have as much of an effect on exercise as exercise has on sleep. Also, people who regularly sleep well may experience these effects very differently than people who have chronic sleep problems.
According to a study published in the Mental Health and Physical Activity journal, a nationally representative group of participants reported a 65% improvement in sleep quality and daytime alertness when they exercised for at least 150 minutes per week. Aerobic activities seem to be best for sleep, as they increase the levels of oxygen that reach your bloodstream. The exact reasons behind exercise helping with sleep are unknown, but there are some theories from the National Sleep Foundation. One is that your body becomes heated during a workout, and the post-workout drop in temperature may promote sleep. Another reason could be that physical activity decreases anxiety, arousal, and symptoms of depression, which may contribute toward sleep problems. By keeping active during the day, it may be easier to deal with stress, and with less stress comes a deeper and more restful sleep.
Sleep also maximizes the benefits derived from exercise. According to the Division of Sleep Medicine at Harvard Medical School, the body performs vital activities during sleep, such as providing an opportunity to recover from being used during the day. Restorative functions almost exclusively take place while asleep, such as muscle growth, protein synthesis, and tissue repair. Alternately, when humans are deprived of sleep it can cause health problems by modifying levels of hormones involved in metabolism, appetite, and stress response. If your body has not had a chance to recover and restore itself, you will not be as fit for activities the following day.
Most studies that look at the correlation between exercise and sleep do not use subjects with existing sleep issues. For people who do not have chronic sleep problems, the relationship between exercise and sleep is not as complicated. For people with insomnia, the relationship between sleep and exercise can become a vicious cycle, the lack of one hindering the other and vise versa. Insomnia can come in many different forms: difficulty falling asleep or staying asleep, waking during the night, non-restorative sleep, and daytime sleepiness.
A study published in the Journal of Clinical Sleep Medicine takes a closer look at a previous study on physical exertion and sleep. It concentrated on sedentary older women with insomnia. They were randomly directed to either remain inactive or begin doing cardiovascular exercises for 30 minutes, 3-4 times per week for 16 weeks. After the 16 weeks, the active group was sleeping much more soundly than they had been at the start of the study. They were sleeping for 45 minutes to an hour longer each night, were waking up less frequently, and were more energized during the day.
What was most interesting though, was the fact that the active participants did not experience immediate results. They did not notice an improvement in sleep the night following a day of physical exertion. In fact, they instead noticed diminished corporeal performance after a night of poor sleep. People with insomnia tend to experience extreme arousal of their stress system. Random single bursts of exercise will not help overcome this arousal, and may even aggravate it. In order to help with insomnia, an exercise routine needs to be implemented and maintained. Eventually the regular activity will start to silence a person’s stress response, and sleep will come more readily.
The process is very gradual, and does not offer immediate gratification. This makes it harder to implement into daily life, because it takes regular exercise several months to show significant and consistent changes in sleep behavior for those with insomnia. And when you are tired, it is hard to motivate yourself to be active, and your workout suffers. Once sleep and activeness become a normal routine, each will benefit the other.
As a whole, sleep and exercise are mutually beneficial, and both help maintain overall health. For people who do not experience regular problems with sleep, these benefits can be reaped almost immediately after implementing regular workouts and sleep routines. For those with insomnia or other sleep issues, it may be a bit harder to find the initial energy and endurance to begin this lifestyle change. Either way, the conclusion of these studies is that regular sleep and exercise should be incorporated into everyone’s lives, and as a pair, they can improve your health!
What would happen if you only ate organic food? To answer just that the Swedish Environmental Research Institute IVL conducted a study on the effects of eating only organics. Watch this short video, The Organic Effect, to see the results.
The decrease in the amounts of pesticides present in the body after eating only organics is astonishing. Buying organic when possible is a great way to have less exposure to chemicals and pesticides used in conventional items. “There were a whole number of chemical removed from my kids’ bodies and I don’t want them back.”

If you work in an office, have a busy schedule and drink coffee everyday… then there is a good chance that you used a share of the 9 billion Keurig K-Cups that were sold last year! And who could blame you? In our fast-paced society, it’s hard to resist the opportunity to have hundreds of beverages available at the touch of a button (and without all the hassle of cleaning out yesterday’s pot of coffee).
A few weeks ago I came across an article on The Atlantic website that confirmed the fear that had slowly begun to creep in as I brewed my coffee every morning: eventually these K-Cups are going to take over! I had already noticed the waste building up in our office, but James Hablin’s article, A Brewing Problem, really opened my eyes to just how big this issue is becoming. If we were to line up all of the K-Cups that were sold in the past year alone, they would circle the earth at least 10.5 times! Not only that, but the K-Cups are made using a type of plastic that is not recyclable in the US…which means that the only home for those 9 billion K-Cups is the landfill.
This knowledge is worsened by the fact that several competitors have successfully designed a recyclable or biodegradable version of the K-Cup…and instead of embracing it, Keurig has trumped the competition by launching a second-generation machine that only works with Keurig-brand cups. Last year, Keurig promised to come up with a fully-recyclable version of its K-Cup by 2020. However, that promise was not enough to stop Egg Studios from producing a theater-quality horror movie about the impending “K-Cup Apocalypse.” While it may be a little far-fetched, this video has certainly gotten people thinking and has lead to the #KillTheKCup movement on Twitter.
By the end of this article, you may find yourself considering giving up coffee entirely (I know I was), but wait — there’s still hope! Somewhere in the course of the past few weeks, a lovely little box (like the one below) showed up in our kitchen. Turns out, there is a way to recycle these things after all! Click here for more information about Keurig’s Grounds to Grow On program.
There may still be room for improvement, but I can honestly say that my Keurig-brewed coffee takes a little sweeter now that I know that the K-Cup can be converted into something useful!
Released in 2007, The Story of Stuff takes a closer look at the linear pattern of our economy. From our constant reaping of the planet’s finite resources to the addition of toxic chemicals to our products and our overwhelming transition to identifying ourselves as consumers, this unsustainable system cannot and will not last forever.
This video illustrates the current flow of our economy and the role that government, corporations, and individual consumers play in the “big picture.” It points out the problems with our current linear model, and the possibility of change to a more cyclical model based on people coming together to make a difference.

Sleep is a complex process, and there is a lot we don’t know or have wrong about it. The Huffington Post just published the article 3 Crazy Myths and Facts about Sleep that clears up several myths with some interesting truths about sleep.
Myth #1: Getting up at night for, say, 15 minutes just means I lose 15 minutes of sleep. Unfortunately, when life wakes you in the middle of the night, you lose way more than just those minutes out of bed. Waking to change your pajamas after a hot flash, answer the phone if you’re on call, or of course, comfort a crying baby is harder on us than we ever thought.
I’m surprised it took until 2014 to officially research this, but a first-of-a-kind study in the journal Sleep Medicine looked at the effects of sleep interruption over two nights. The first night, all the study participants slept for eight hours. Then researchers then measured their mood and ability to pay attention. Good so far.
A few nights later, the participants were split into two groups: half slept for only four hours, while the other half slept for eight hours but got woken up four times for 10 to 15 minutes at a stretch. So technically, they spent at least seven hours asleep — three hours longer than the four-hour group — just interspersed with awakenings. Then everyone’s mood and attention was measured again.
Anyone who’s ever had a newborn or been on call for work knows the results: the mood and attention of folks with interrupted sleep were just as bad as those who slept for only four hours. Both groups felt depressed, irritable, and had a hard time getting going. Plus, performance on the attention task got worse the longer they kept at it. Indeed, whoever coined the term “sleep like a baby” clearly never had one.
Myth #2: My brain holds my internal clock. Yes, the master clock, technically called the suprachiasmatic nucleus, or SCN, is in your brain. But almost all your organs, plus your fat and skeletal muscle, follow some sort of daily rhythm as well. Your gut, liver, and kidneys in particular have strong rhythms.
That’s why you feel so lousy when you have jet lag, and that’s why you often wake up groggy or feeling thrown off when you sleep in on the weekend: your whole body is affected.
And over the long term, throwing off your body clocks through overnight shift work, frequent jet lag, or just wacky sleep habits can put you at risk for some serious diseases, including breast cancer and colon cancer.
Circadian disruption is also thought to be a final push that sends some of those merely at risk over the edge. For example, only 30 percent of alcoholics develop liver disease. Why? Well, a 2013 study found that circadian disorganization, common in shift workers, increases “permeability of the intestinal epithelial barrier,” or in other words, a leaky gut. In the context of what the researchers called “injurious agents,” i.e., booze, a leaky gut puts folks at higher risk for liver inflammation and disease. They concluded that while there are many factors that determine whether someone with alcohol addiction develops liver disease, circadian disruption may be a swizzle stick that breaks the camel’s back.
Myth #3: If I can’t sleep, I should just wait it out… sleep will come. On the contrary, if you know you’ll be staring at the ceiling for awhile, get up. Yes, your bed is cozy and warm, but here’s why. Much like you probably associate biting into a lemon with puckered lips and Pavlov’s dog associated the bell with food, thereby salivating, you want to associate your bed with one thing: sleep (well okay, two things: I’ll let you guess the other).
When you lie in bed for more than about 15 or 20 minutes without sleeping, you start to associate your bed with wakefulness. And when you watch TV or fool around on Pinterest in bed when you can’t sleep, those too become associations with bed.
With time, bed could mean sleep, or it could also mean CSI, preschool science project pinboards, or planning your day in your head. Yes, even thinking and worrying qualify as activities you don’t want to do in bed.
So what to do? You can still do all these things, just don’t do them in bed. Get them done before you head to bed, and if you can’t sleep after 15 to 20 minutes, get up and do something non-stimulating like reading (on paper, not a tablet!) until you feel sleepy. Then try again. If you still can’t sleep, rinse and repeat: get up again to avoid associating the bed with anything but sleep and sex.
This is what behavioral psychologists call stimulus control and it’s the most effective way to combat chronic insomnia. It may take a week or two, but it’s been shown to break the bad habits that maintain insomnia. Before you know it, you’ll be so good at sleeping you’ll do it with your eyes closed!
