Is 10 Minutes of Daily Exercise Enough? Make Your Healthy Minutes Count

It seems that for health, the range of exercise—there’s always the proverbial range—is between 30 to 90 minutes daily for at least five days a week.

Can any one really lose weight exercising ten minutes a day? If so, which exercise is best? Could it be done in six or eight minutes?

Confused about what to eat? You’re not the only one. How long should you take to consume a healthy meal, once you discover that perfect diet? For example, how long does it take to chew a cup of broccoli or a bunch of raw kale so that it’s sufficiently soft enough to digest?

How many minutes every day do we need to spend to be healthy, fit, and slim?

Let’s Start with Sleep

To figure out your healthy minutes, let’s start with sleep. Perhaps the single most important part of our day is spent in bed. Typically, we rest in bed (or on the couch), have sex in bed, sometimes watch television, and almost always sleep in our bed. And, sometimes we have breakfast in bed. When sleep scientists did the math, it turned out that we spend on average about 2,372 hours in bed every year. That’s about 6.5 hours a night.

Is that enough sleep?

You can get by on 5-6 hours of sleep a night, but to be healthy, which includes enough time for the brain to detoxify itself and for the immune system to reboot, we need between 7–9 hours of restorative sleep each night. Children and adolescents need much more: up to 12 hours a night, because those are the ages when the brain is developing the most.

It’s a given that sleep is really important, and I’ve written on that in other blogs, so let’s look at the number of minutes during the daylight hours that we need to spend on our health.

The 2-Minute Rule

What’s the first thing you do in the morning when you wake up? Do you exercise? Practice yoga? Eat? Drink tea or coffee? Take the dog for a walk? Wake up the kids? Pick up where you left off on your novel?

I greet the day by going outside among my plants. I enjoy the brilliance of early morning rays of sunlight while slowly watering the orchids and fruit trees. Then I pray or meditate. For nourishment, I drink green tea or organic coffee, and in the winter drink ginseng soup; then I have a light breakfast. And then, brush my teeth.

The American Dental Association recommends brushing your teeth at least twice a day for 2 minutes. That includes flossing, brushing with a soft bristle brush, and rinsing. Some oral hygiene specialists advocate brushing for 3 minutes: 1.5 minutes on the lower and 1.5 minutes on the upper teeth, twice daily.

Americans are a rushed nation. Who has time to devote several minutes to tooth brushing? But gum and dental health are very important. Turn on the timer on your smart phone to count the minutes you brush your teeth. You may be surprised at how long that really is!

100 Bites

My mentor, Dr. Bernard Jensen, was famous for paraphrasing Mahatma Gandhi’s aphorism: “Chew your juice and drink your food.” By that he meant that raw vegetable juices are beneficial for the body, but have to be prepared for digestion and absorption in the mouth. You need to mix juice well with saliva, which begins the enzymatic process, increasing nutrient absorption.

Don’t gulp your carrot or wheat grass juice. Drink fresh juices in small amounts or sips, swish as you would with wine to mix with saliva, and then swallow. If you’re thirsty, drink water or sip green tea.

How long should you take for lunch? In traditional societies, people enjoy leisurely meals. Not in America. We have fast foods during power lunches that fit our hyper lifestyles. We are a nation of overachievers and underchewers. But that’s not healthy.

Americans are famous for extremes. The original health-food faddists, like Horace Fletcher, believed in slowing chewing every mouthful 100 times; a chore that could take up to 10 minutes per bite. In his day, around 1912, Fletcher’s followers included generals and presidents, and famous writers like Henry James.

Modern health experts, however, don’t endorse that extreme. Research has shown that eating smaller bites and chewing longer—in effect, eating slower—promotes normal weight because the stomach signals the brain that you’re getting full. This satiety effect starts about 20 minutes after the first mouthful.

100 times per bite seems extreme. The right number of bites per mouthful seems to be between 20 to 50 times. The Indian nutritionist Naini Setalvad, who considers correct chewing the first mantra of healthy eating, recommends about 30 bites. The Japanese health ministry recommends that every citizen chew 30 times per bite. I agree—30 seems like a good number.

It takes 25 to 30 seconds to chew a mouthful of cooked food 30 times, longer for fibrous raw vegetables or meat. In traditional societies, meals can linger between 1 to 2 hours. Maybe 2 hours is too long, but certainly the 30-minute American lunch break is not long enough.

“Good digestion,” Dr. Jensen said, “begins in the mouth.” But simply reducing healthy eating to chewing is reductionist and oversimplification, and makes for a boring meal. If we use our molars more, however, masticate better, and slow down while eating, we’ll be healthier.

35 Minutes of Sweat

From my clinical experience, I don’t believe that 8 or 10 minutes workouts, unless they’re done intensively three times per day, make a significant difference in health or weight. True, some exercise is better than none, but an optimal amount is preferred when possible.

What’s considered optimal?

Exercise, like sleeping and eating, is personal. There are guidelines, though, that have proven beneficial for everyone. It seems that for health, the range of exercise—there’s always the proverbial range—is between 30 to 90 minutes daily for at least five days a week. Every one is different. Some people feel better with longer workouts. Some of us do best with short bursts of activity. Older people can take it slower, while younger people need greater intensity.

Scientific studies as far back as 1981 found that daily exercise improves mood, enhances metabolism, and prevents many diseases, including breast cancer. The average number of minutes for a healthy exercise routine appears to be 35 minutes every day. The key is that those 35 minutes need to be intensive enough that you cannot chat with a friend, and you have to sweat.

How Do You Spend Your Precious Time?

It’s not just the time we spend sleeping, eating, or chewing that is important. The time we spend on other things are also central to health, including downtime, sex, friendship, rest and relaxation, and laughing. We spend too much time in our cars on the freeway and too much of our valuable lives wasting time watching television.

Additional Tips For a Healthy Use of Your Time

  • Cuddle more
  • Laugh more
  • Read more
  • Listen to relaxing music more
  • Love more
  • Learn more
  • Spend less time waiting in line
  • Spend less time on the internet or on hold
  • Spend less time watching television
  • Spend less time in your car alone on the freeway

We are creatures of habit. Our biology, cycles, and needs are dependent and shaped by the influences of Earth, sun, and moon. Some would say that other planets and even stars have sway on what we do, our moods, and even our choices. We also have free will, of course, and the option to choose what we do and how we behave, and how many minutes we spend each day doing positive, healthy things.

    I exercise almost everyday, but like 20 minutes at most. I’ll try to do 30 minutes in 2015:) Also the infamous 30 time chew in Japan. I didn’t know the government recommends that, but my mom told me to chew 30 times and so did my grandparents. It’s a standard in Japan. Chew 30 times, otherwise you can’t digest anything. Nothing!! LOL

    Love such practical information. Have some of my own. Should be able to talk during exercise. (How could women stop talking for that long?) Also, laugh ! My instructor encourages us during fast pace 10 min cardio aerobics to repeat words, change directions, challenge our brains. If we are too winded to even answer her fun words, we are not breathing properly. If we can sing, then, we are not working hard enough. Not everyone sweats. I start after a few minutes, as I put so much of myself into work out. And, my Dear Doctor, we ladies do not sweat, we GLOW!

    Dislike eating with others. They inhale their food. Do not know what it is to chew or digest their food. Their all done, I, haven’t eaten quarter of my food, stop enjoying it, as they are staring at me, like what’s wrong with her? Taking time to slowly chew food, keeps one from overeating. Then, they wonder, how I maintain my weight, they cannot. Same goes for exercise, faithfully taking 30 min some days, other days might be 45 or 60 min. Not being rigid, but disciplined, to do something enjoyable at least 5 days weekly.

    Oh, just love additional tips ! ! Hugs are healing! Cuddling brings comfort! Love creates life! Reading is relaxing. Music calms our moods.

    Let us not be creatures of habits. Make changes that will bring love, laughter, joy, contentment, security, excitement, spirituality flowing into our lives. So, then it will over flow into others. Then, we will never be lonely or feel forsaken, filled with happiness that is contagious. Truly blessed, in spite of a world that is filled with chaos.

    Thanks for a great overview of some important components of health. These are achievable and not hyped up goals that lead to frustration and disappointment. A good reminder list to post on the refrigerator!

    Yes, definitely agree on the amount of sleep!

    My morning routine (I work free lance so can organise my own time) is to wake naturally, get up and make a cup of English breakfast tea (I’m British) and take it back to bed; then repeat!

    Then get up and run a small bath (slowly) and check my emails.

    Have a quick bathe, clean teeth, do ten minutes exercise including weights, press-ups, bending and stretching. (I never sweat (Glow Ahahaha) then get dressed, check the woodburner, feed my two ponies and have my own breakfast of fresh vegetables, humous and avocado, another cup of tea, plus supplement’s (I’m more or less vegan) and start on my most pressing report.

    If I need to be somewhere early, it all goes ‘out of the window’… but this routine seems to work for me. Sometimes at night I put music on, such as Shade or Corinne Bayley Rae and dance to it.

    Always keep time for friends and family and go abroad once a year usually to see family or sometimes to explore a new country

    While i believe, practice and endorse most of this article i am compelled to point out that the dental health aspect was over simplified and not very informative. Now, i realise that you could do a whole huge article on oral health care alone, and i believe i have read at least one informative article from you on this but still i feel i need to pass some info on so that it’s not so open-ended. I think it’s very important to note that evidence is piling up that fluoride only has one really good use, rat poisoning, and that new studies suggest that flossing, oil pulling and brushing with cold pressed organic coconut oil based pastes are far better for teeth than the lies dentists spread. For example, most dentists will never tell you that teeth can be cured of cavities with mineralization just as doctors will never tell you that there are many many natural cures for cancer and most other diseases out there. It would truly be awesome to see an article on the benefits of colloidal silver, chaga and sour sop sometime Kev!! Live awesome!!

    I always enjoy articles by Dr. Williams.

  7. Nieves says:

    Good article! We need more in this area, also in dentistry. Give us more of this type of information in 2015. Thanks!!

    Regarding the number of times to chew, I was told many years ago, that we have 32 teeth and we should chew each mouthful 32 times.

    The article refers to chewing a bunch of raw kale. I recently listened to a Thyroid summit hosted by suzie Cohen, a compounding pharmacist, that interviewed about 30 medical people. They stated that a person should only eat 2 to 3 spears of raw kale. at this amount it increases your folate levels. Eating a greater volume of raw kale was said to make your thyroid under active and should be eaten cooked. One speaker, a health researcher, suggested to get a true folate level to have a RBC folate test.

    About three years ago I started oil pulling with coconut oil every morning. first thing, prior to brushing my teeth, eating or drinking. I read that coconut oil kills bacteria, viruses and fungi. I swish it around making sure it covers all my gums for a minimum of 10 minutes, but usually 20 minutes. I then spit it in to a plastic bag and put it in the rubbish bin. Apparently spitting down the sink can block the sink, as the coconut oil will solidify. I also use a tongue cleaner after spitting out and then brush my teeth. Since I have been doing this my dentist has each time I have visited told me that my gums are perfect and I do not require a clean. Previously I had a clean every year. I found the book The new arthritis cure by Bruce Fyfe very useful. There is also a website (Please note that you need to spell “center” the way Americans spell it. If you use centre the website does not come up.

    Years ago, my acupuncturist suggested, that each time i park the car, to sit for a few minutes before getting out. It is great for resetting your nervous system and getting a bit of a lift in energy.

    I don’t know about mineralisation regarding dental health, so would appreciate an article on that topic.

    Good health and joyful living, to everyone around the globe

    I have heard from several sources, one being Dr. Weil, that chewing gum is not a good practice because when we chew anything it stimulates the secretion of digestive enzymes and that we only have a fixed lifetime quantity of digestive enzymes so you don’t want to stimulate them without purpose.

    My question is, based on the above: Are 30 chews really needed per mouthful or are we using up more valuable digestive enzymes than we need to with that recommendation?
