May is “National Biking Month”. I celebrated today to pick up my cello from the string shop (it had needed re-hairing) by bike – something I had not done before.
I had not used my bike on that route before because most of the 2.8-mile drive there is on a very busy – to me meaning: dangerous – road, with horrendous traffic. I set out anyway, and found out that there is a path along the highway, mostly hidden in the bushes, much safer than riding on the highway itself. Although it was narrow and overgrown – I had twigs whipping my face and lots of distracting dirt and debris underfoot, oh, underwheel.
But it was doable. Google Maps thought I should be able to paddle the 2.8 miles in 16 minutes. It took me about 25. But the weather was as gorgeous as one expects of May, and it gave me a wonderful work-out.
Here are my rules I stick to:
• I never go without helmet.
• I don’t bike two days in a row because I want to give my muscles a day for recuperating in between.
• I don’t bike when I am in a hurry – because that’s when accidents happen.
My bike needed a few adjustments before I could use it for errands like shopping. I had a rack installed in the back, with a basket. And I needed an old-fashioned handlebar. The original one seemed to be made for a racer – which I am not. The new one is comfortable and does not strain my neck. The other day, when we were in Rome, we took bikes along the Via Appia antica – the old road build by the Romans more than two thousand years ago. My Italian bike had one of those comfortable handlebars. And, by the way, those bikes were rented – free of charge. Wish we would have that system here! The Via Appia ride will be unforgettable!
And for the very occasional use during dusk (I don’t anticipate driving at night), I plastered the bike with a set of reflectors. And I bought a fun bike bell – just like I had as a child!
These are some of the health benefits of bicycling:
1. Gets you outdoors.
2. Improves your mood.
3. Gives you light and sunshine for vitamin D repletion.
4. Fights overweight.
5. Moves your bowels better.
6. Strengthens your heart.
7. Builds up your muscles – strength as well as muscle tone.
8. Tones your pelvic area (and is more fun than Kegel exercises!).
9. Improves coordination and balance.
10. Promotes longevity.
11. Increases endurance and stamina.
12. Boosts your immune system.
Riding a bike is one of the healthiest choices you can make for yourself and for our Earth – as long as you avoid being run over by a car! Read More

Have You Coddled Your Hippocampus Lately?
February 2, 2011
A recent study shows that brisk walks boost memory in older adults. And makes your hippocampus swell visibly on MRI. I bet this also applies to younger people.
The hippocampus is a worm-like structure deeply buried in your brain that is involved in memory formation. In Alzheimer, it is the part of your brain that will show the first signs of degeneration. A youthful hippocampus gives you mental plasticity, the opposite of which would be the obnoxious inflexibility that some older people show. About six to nine miles a week in this study was linked to better brain function. Walking even more did not seem to have more effect on the brain.
It comes down to walking ten minutes in one direction, turning around and walking back ten minutes, which can be done during lunch hour.
Another study showed that people who walk faster live longer. That bodes badly for me – I am a slow poke. But we can safely deduct that people who don’t walk will not make it long at all.
Walking also boost mood. If I would be a moody person (which I am not), I would do three things: go for a daily walk during daylight, end every hot shower with a cold one, and take herbal preparations – in women particularly, herbs against PMS or helping with post-menopause. Not to mention that I would turn to fresh, nourishing food and away from junk.
Walking per se is good for you. Two other studies have shown, that the effect is even better if you walk on uneven surface – like on pebbles, at a beach or in hilly terrain. Walking on pebbles decreases high blood pressure, and makes you less likely to get Parkinson’s. Using more muscles and consequently more brain can explain these results.
The most dramatic effect, I think, that daily walking can have – besides on memory, longevity, hypertension, Parkinson’s and mood – is that light boost vitamin D production under your skin – even if it is just the pale little area of your face reaping the rays. Vitamin D has become an important research focus as it wards off bone loss, cancer, multiple sclerosis and infections.
Walking will also lead to less weight and fight the dreaded metabolic syndrome (diabetes, high blood fats and hypertension) better sleep – all exercise does. And better sleep has been shown to increase overall performance, mood and resistance to infections.
In New England presently, walking the icy streets among huge snow banks is not that enticing. But I bet snow shoveling has all the above benefits, too – if you avoid hurting your back and don’t slip on the ice. At least I hope. Because I spend the morning digging out our walkway and garage driveway. At least this I know: The cold stimulus is a trigger for better immune function: Snow-shoveling in freezing temperatures improves my ability to better fend off flu and the common cold. Read More
