Health and Fitness in One Page

Over the last six years I have tried to answer the question “What is a Healthy Lifestyle?”. The following is a brief summary of what I have learned. By applying what I have learned I am in better condition in my 50s than I was in my 20s. In the coming months I will do longer posts that look at each of these areas in more detail.

Sleep At Least 7 Hours

There is ever increasing evidence that sleep is absolutely critical to a mentally and physically healthy life. It is believed healthy adults need between 7-9 hours of quality sleep each night and children require even more sleep. While we don’t yet fully understand all of the ways sleep impacts our health, there are a number of important processes that primarily activate while you sleep, particularly during the deep, delta wave stage such as:

I experienced the importance of sleep first hand when my body rebelled after a nine month period when I was averaging less than 4 hours of sleep / night. It took years for me to fully recover. I was further convinced of the importance of sleep by the book The Promise of Sleep written by one of the pioneers in sleep research. Since this book was published there have been numerous studies that only strength the case for sleep.

Eat Healthy Foods

Lifehacker’s the onlythree things everybody agrees on is a good starting point when developing a healthy diet. I would elaborate / expand their list slightly

  • Eat as many non-starchy vegetables as you can, especially those that have deep colors. The caloric density of these vegetables is small enough that you will not eat too much. The vegetables are packed with health promoting micro nutrients and good quality nutritional building blocks. This will also get your fiber consumption up to an healthy level. Fiber is critical to your micro-biome health.
  • Limit or avoid highly processed food including bread, pasta, fruit juices.  A combined Stanford and NIH study found that when it come to weight lose, the quality of food was the single most important factor.
    • Minimize the sugar in your diet, and eliminate any products that have added sugar. There has been significant evidence since the 1960s that sugar is directly linked to a number of health issues including heart disease.
    • Eliminate all “foods” which are high in trans-fats. There is significant evidence that trans-fats have only negative impacts to health.
  • If you eat meat, focus on cold water fish and free-range / grass fed animals
  • If you need additional calories: eat whole foods such as beans, lentils, nuts, or fresh fruits. 

A great resource for thinking about healthy eating is Reframe Health Lab’s Healthy Eating page which contains links to a short screencast and several resources available on the Internet.

Stay Active… Move!

Our bodies are made to move and our brains are made to direct that movement. One of the most natural and health promoting activities is walking.  We should walk at least 30 minutes each day, ideally walking several hours to accumulating 17,000 steps / day. Besides the physical benefits, walking engages our brain, strengthen our creativity, and ability to focus.

Vigorous exercise has many positive impacts. It helps control stress hormones, strength the circulatory systems and metabolic systems.  It is often recommended that we should engage in at least 30 minutes of physical activities that raise your heart rate to above 80% maximum 3-5 times a week, with 2-3 of these exercise periods to include strength exercises. There is a growing body of evidence that suggests a high intensity interval training (HIIT) program could produces the same results in 30 minutes /week what more traditional aerobic training programs accomplish in 90-300 minutes.

Push Beyond Comfort Zone

Humans are the most adaptable species on the planet. Our adaptability comes from our bodies natural ability to physiologically adapt to highly varied conditions as well as our ability to transform the environment we live in. Civilization has favored adapting our environment to provide a “comfortable” experience rather than encouraging people to exercise their physiological adaption “muscles”. I believe we need to periodically move outside our comfort zones so our body doesn’t “forget” how to adapt to changes. Example of the adaptability we should cultivate:

  • High Intensity Interval Training (HIIT) produces better performance improvements than more static training in short periods of time.
  • Short duration exposure to heat (sauna) and cold (ice baths) improves overall health in numerous ways
  • Periodic fasting reset several human systems and can be an effective treatment for several conditions.

Practice Mindfulness

Thanks to Paul Roy to mentioning that something should be added…

There is a growing body of scientific evidence, not to mention millennia of traditions / wisdom that a intentional mindfulness in the form of meditation or contemplative prayer literally re-wire our brains for the good producing improved physical and mental health. There is stunning imagery from fMRI scans while people practices these disciplines showing changes in the areas of the brain that are activated. Mindfulness can improve empathy and gratitude which in turn leads to more joy in everyday life which results in a significant protective effect to health. Gratitude and joy, unlike happiness are not dependent on external circumstances, but rather are an internal response which we can choose. Though I am not Catholic, I found the Spiritual Exercises of Saint Ignatius to be very helpful. A while ago I wrote about how start with the mind and spirit might be the best way to improve the human condition.

Have Strong Social Connections

The Harvard / MassGeneral  Adult Development Study started in 1939 has studying the the lives of two cohorts and now their children found that one of the strongest predictors of a healthy (and happy) life was an individual’s quality of social relationships. Researcher Susan Pinker found that the secret to living longer may be your social life due to the correlation between social connections and people who are 100+ years old.

Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, for you were bought with a price. So glorify God in your body.

I Corinthians 6:19-20
