Intense Exercise Provides A Powerful Health Benefit!

It’s a challenge for all of us to exercise. It’s especially difficult to do so during medical school. If you’ve fallen off the wagon, here’s a new study that will encourage you to begin again.

A new research from Brigham Young University reveals you may be able to slow one type of aging–the kind that happens inside your cells. As long as you’re willing to sweat.

“Just because you’re 40, doesn’t mean you’re 40 years old biologically,” Tucker said. “We all know people that seem younger than their actual age. The more physically active we are, the less biological aging takes place in our bodies.”

The study, published in the medical journal Preventive Medicine, finds that people who have consistently high levels of physical activity have significantly longer telomeres than those who have sedentary lifestyles, as well as those who are moderately active.

Telomeres are the protein endcaps of our chromosomes. They’re like our biological clock and they’re extremely correlated with age; each time a cell replicates, we lose a tiny bit of the endcaps. Therefore, the older we get, the shorter our telomeres.

Exercise science professor Larry Tucker found adults with high physical activity levels have telomeres with a biological aging advantage of nine years over those who are sedentary, and a seven-year advantage compared to those who are moderately active. To be highly active, women had to engage in 30 minutes of jogging per day (40 minutes for men), five days a week.

“If you want to see a real difference in slowing your biological aging, it appears that a little exercise won’t cut it,” Tucker said. “You have to work out regularly at high levels.”

Tucker analyzed data from 5,823 adults who participated in the CDC’s National Health and Nutrition Examination Survey, one of the few indexes that includes telomere length values for study subjects. The index also includes data for 62 activities participants might have engaged in over a 30-day window, which Tucker analyzed to calculate levels of physical activity.

His study found the shortest telomeres came from sedentary people–they had 140 base pairs of DNA less at the end of their telomeres than highly active folks. Surprisingly, he also found there was no significant difference in telomere length between those with low or moderate physical activity and the sedentary people.

Although the exact mechanism for how exercise preserves telomeres is unknown, Tucker said it may be tied to inflammation and oxidative stress. Previous studies have shown telomere length is closely related to those two factors and it is known that exercise can suppress inflammation and oxidative stress over time.

“We know that regular physical activity helps to reduce mortality and prolong life, and now we know part of that advantage may be due to the preservation of telomeres,” Tucker said.


12 Ways to Become More Positive and Improve Your Health!

Did you know that positive emotions broaden our thinking and enhance our health, mental flexibility and coping skills?   Even temporary experiences of positive emotions can have lasting consequences. They give us a solid foundation upon which to allow the birth of new internal resources that will support our well-being on an ongoing basis. They also counteract the brain’s innate tendency to engage in negativity, thus promoting internal balance, lowering the body’s stress response, helping us recover from stress more rapidly, and granting greater functioning after stress.

Optimists, live an average of seven years longer than pessimists.

Having a grim or pessimistic view of the future, which means having an expectation of negative results or fewer positive results, has been shown to lead to earlier death and a more rapid progression of the diseases of aging. Being optimistic and expecting good things to happen relates to better health. Positive emotions help us to develop hardiness and resilience (the ability to transcend our challenges) when they are firmly grounded by self-awareness and acceptance. They allow us to not only survive but thrive.

Psychologist, Barbara Frederickson, Ph.D., is famous for her ‘broaden and build’ theory on positive emotions. Fredrickson’s research shows that the more we focus on, and build, our repertoire of positive emotions, the broader the application of our positive emotions and their benefits become.

Here’s a twelve step tool kit that can help increase your level of positivity.


The Twelve Step Toolkit

Supporting you in your quest to build positive emotions, Fredrickson suggests an easy to use toolkit  of twelve techniques to help cultivate positive emotions. Which of the twelve suggestions appeals most to you?

Tool 1: Be open

Fredrickson urges us to adopt the motto “be open”. This first tool invites us to temporarily put expectations and judgments aside and allow ourselves to be mindfully present in the moment. For example, on your morning walk, ignore the mental to-do list and practice being open to nature.

Tool 2: Create high-quality connections

Fredrickson suggests we connecting with others in a meaningful way. She cites the work of Jane Dutton, cofounder of the Center for Positive Organizational Scholarship at the University of Michigan) who’s research points to four ways to build these high-quality connections.

  1. Be present, attentive and affirming by fully focusing on others &encouraging their endeavors.
  2. Show support for what the other person is doing – do what you can to help them succeed.
  3. Demonstrate trust – believe that the person can meet your expectations (and let it show).
  4. Allow time for ‘play’ – spend time with this person occasionally with no outcomes in mind.

Tool 3: Cultivate kindness

Commit five acts of kindness every day. You can do this by assessing what those around you need the most and find positive ways to make a difference to them.

Tool 4: Develop distractions

Distractions break the grip of negativity. The goal here is to shift your focus away from anxieties and troubles. Fredrickson suggests making two lists, one of healthy distractions and the other list of unhealthy distractions. Healthy distractions might include going for a bike ride, walking your dog, playing a game with your child or a friend, reading a novel, etc. Unhealthy distractions to avoid might include excessively eating, drinking alcohol, or playing video games for hours. Aim for any activity from the list of healthy distractions.

Tool 5: Dispute negative thinking

This exercise is adapted from Martin Seligman’s work into depression prevention at Pennsylvania University and teaches us to dispute our negative thoughts. On a set of index cards write your typical negative thoughts, such as “I always do this wrong, how will I ever get any better at this?”, “why hasn’t she called by now? Doesn’t she care about me?” Whatever your typical negative thoughts are, make sure they are included on the cards. Once you have written your set of cards shuffle them and pick one out at random. Read it out loud. Next, as quickly and thoroughly as possible, dispute it out loud. What are the facts? When you are satisfied that you’ve dismissed the negative thought, move on to a different card. Negative thoughts can be automatic; the purpose of this exercise is to ensure they are nipped in the bud as quickly as they occur.

Tool 6: Find nature nearby

Locate a dozen natural spots that you can get to in a matter of minutes that connect you to trees, water, skies or greenery when the weather is good. Connecting with nature has been shown to boost positivity. Make these places a regular destination.

Tool 7: Learn and apply your strengths

You can take a free online strengths test at the University of Pennsylvania’s Positive Psychology Center and learn your 24 signature strengths and how to apply them. Once you have established your strengths plan to use them every day. Consider and address the changes you might need to make to do this.

Tool 8: Meditate mindfully

Sit in a quiet place for a few minutes and take several deep breaths. Notice how it feels. Where do you feel your breath? Continue to observe your breath. The goal in attending to your breath here is to practice being present in the here and now. Invariably, your mind will wander. Allow it to wander, don’t chastise yourself for these wandering thoughts, just notice your attention has strayed and return your focus to your breathing to continue to stay present.

Tool 9: Meditate on lovingkindness

Start by focusing on your breath and the region of your heart. Once you are focused here, reflect on a person for whom you have warm, tender or compassionate feelings. Your goal is to connect to warm and natural feelings by visualizing how being with this loved person makes you feel. Once this positivity has been created within you, let go of the image of the individual and hold the feeling.

Tool 10: Ritualize gratitude

Being grateful means you notice gifts and appreciate the people around you. Use this tool to take stock of what is good in your life. Doing so draws your attention to positive events.

Tool 11: Savour positivity

Choose a source of love, joy or pride and a willingness to think differently about these sources. Think of a past moment when you enjoyed an experience or being with someone important to you. Allow yourself to examine the images from all angles. Recognize the value of these good feelings for your mindset and practice savoring them.

Tool 12: Visualize your future

In this journaling exercise, imagine yourself five years from now after everything has gone as well as it possibly could. You have accomplished all the goals you set yourself. Write down where you will be and how it will feel when all of your goals have been achieved.

After a week or so, review what you’ve written and from this draw out your life’s mission. What purpose do you want to drive you every day? What’s the meaning of your existence? Contemplate these big questions and put your thoughts in your journal, then distill them into a mission statement. Create a ten year plan to help you meet your mission. Reduce your plan to bullet points to support you in current and future decision making, moving you towards your goals.

Putting the toolkit into practice

You can try just one of the above tools or you can try all of them and see which works best for you. Either way, take the test on Prof. Fredrickson’s website to find your level of positivity before and after using these techniques
