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

Vagina: Keep Her Young!
December 8, 2010
Warning: If this offends your sensibilities, don’t read it!
When you have reached a certain age, people often comment on your looks: “You look ab-so-lute-ly faaa-bulous!”
Yeah. But how do you feel? How does your vagina feel – the part of your body that’s invisible, most of the time?
I happen to think that your vagina comes right after your brain in ranking organs for importance. And I think there are ways to keep her happy – and keep you happy. Responsibly, of course – that goes without saying.
Sexuality, I think, has been given to us for a bit of joy in our earthly travels. As a physician, I have observed that different vaginas can exude different levels of exuberance. As a woman, I have decided that I want to keep my precious parts healthy and vigorous. It’s for you to decide if you want to have a sad, smelly pouch down there – or alive tissue that vibrates with vigor and health and lust.
These are a few ideas, starting with movement:
• Kegel exercises, of course, are designed to preb=vent/improve the drooping of internal organs called prolapse. Nobody does Kegel exercises however because they are so boring. But if we would do them, we would benefit: Our internal organs would sag less, and get more blood supply – always a good thing.
• Alternatively, Chinese women have two small balls that are inserted into the vagina. While you walk you try to not let them fall out. This exercises has the same effect as Kegel’s – only they are more fun. The balls usually are made from shiny metal, come always in a box of two, and one has a tiny chime inside. Sounds a bit un-puritanical, though.
• My own method: Standing on one leg while brushing my teeth. It strengthens the whole pelvic musculature – with no extra time and effort.
• Using it, of course. Use it, or lose her. If you don’t have a partner, be diligent yourself. Don’t attach moral values to a bodily function that makes you happy and relaxed and keeps you young.
Now comes water:
• Drink enough fresh water and herbal teas to keep a good turgor down there.
• Cold sitzbath: This is not for the faint-hearted, especially not during the frigid times of year. But the benefits are great. Fill the bathtub with about one to two inches of water (use the time when the water is running to wash your breasts with cold water until they tingle with cold and life). Sit down. Move your legs to let the water swash over your thighs. Count to twenty-one. Get out. Towel well. If your feet are cold afterward, walk on your toes, jump on the spot, go for a walk – do anything to get warm fast again. – A cold sitzbath should not be done if you have a cold, an acute urinary infection, fever. Your body needs to be warm before you start. And never let the cold water swap over your kidney (waist) area; the cold water would use up your chi, as the Chinese say, weakening your whole system. Kept down at your vagina and legs, the cold water invigorates tired old tissues – a rejuvenating treatment.
• Don't use soap down there. This is - right after your eyes, I'd say - the most delicate area of your body, and you wouldn't rub soap into your eyes. The daily cold sitzbath will clean you well enough - provided you wash yourself with a fresh cloth after each defecation - don't wipe forward; always backward! When you take a shower and use shampoo, get a bit of the shampoo on the outside area - not inside or between the folds.
• Don't douche yourself - I said: DON'T DOUCHE YOURSELF! There is a light animal smell down there (if everything is healthy) which is a sign of health - you don't want to smell there like lilies of the valley!!
Herbs:
• Because every woman’s body is different, it sometimes takes a few trials to find the right herbal formula. I am partial to GAIA herbs and use their formula (they don’t pay me to say this!). But others work well, too. I often recommend single extracts, and put them together like black cohosh, red clover, wild yam and ginkgo biloba. Some women blossom if you add vitex to the formula. Female PMS and menopausal herbs do not only keep you healthy down there, but influence your whole body. Especially, they address the mood swings and depression that often come with declining hormones. And since they are not hormones, phyto-estrogens don’t have the same bad side-effects as hormones – don’t let your doctor talk you out of them. All studies about cultures where the diet is high in natural phyto-estrogens have shown very low breast cancer risk.
Food:
• As always, fresh food feeds the inside of every little cell in your body. Don’t think there is a shortcut for good food or cooking at home. No “nutritional” bar or restaurant can match the simple goodness of a cabbage dish made at home (cabbages, remember, are full of cancer-fighting agents).
• Food also plays a role if you want to avoid the smelly part: Everything that gives you gastro-intestinal troubles gives you overgrowth with wrong bacteria and yeast - and they might wander into your vagina (and will, given any chance!). If you have a "smelly" problem, consult your physician because it could be a case of trichomonas or any other sexually transmitted disease. And if nothing else helps, try a better diet: Leave out gluten, dairy, sugars, sweeteners and white starches.
• And don’t fall for that soy scam: The only soy products that are good for you are fermented ones (miso, real soy sauce, tempeh). Stay away from the GMO-tempered soy mono-crop that is destroying the rain forests in South America and does nothing for your health – or for your vagina.
• Use a probiotic if you have an odor - that helps your gut health. And use plain cultured yogurt in your vagina twice a day until the problem is gone.
Sleep:
• Get enough sleep because nothing in your body works when you are tired – and you certainly can’t make a tired vagina wake up by sitting all night on her in front of the computer. Read More

How the World Plays Your Brain
December 1, 2010
In the past, I have written about junk food that feeds the bad bacteria in your gut – and how this makes you think even more of unhealthy treats: You eat a hamburger, then suddenly you crave a donut (or a bag of donuts), and then you needs some twinkies and a soda to flush them down.
I have likened this process to a computer virus: The bad gut bacteria send messages to your brain, sidetracking your best intentions for healthy eating.
There are a few other players who fiddle with your brain, make you fatter and fatigued, and thus prevent you from reaching your goals in life.
Too little sleep is one of those players. If you haven’t gotten the amount of sleep your body needs – and the individual requirements differ, usually between seven and nine hours. If you get away with five to six hours a night, chances are you are using up your bank account of health.
Too little sleep produces stress hormones the next day, and stress hormones like cortisol make you eat more – ergo, weight gain.
A day is made or broken the night before: Can you find into bed early enough – or are you staying up too late, get unrestful rest, and have a sleep-deprived hangover the next day?
And here are two more players that wreak havoc with your brain: computers and TV. Both keep you busy and interested much longer than they should. Captivated as you are, you don’t heed your body’s little signals that it is time to go to bed. You go on working, watching, playing – and so the next day is spoiled because you have to run on less energy. Once you creep into bed, you have a hard time falling asleep. Or you wake up too early. Because staying up late disrupted your sleep-wake-cycle.
Being tired produces more stress hormones. And those makes you eat more.
The holiday season is a time of high stress and tons of running around because you want to bring joy to your loved ones. This year, try this sneaky little trick: No machines (TV, computer, electronic games) after dinner. Take a book, read, listen to music, ease into slumber time – between eight and ten o’clock. If you wake up in the middle of the night, don’t toss and turn. Take this gifted time for thinking what you want to do with your life, what is important to you. And snuggle back into the pillows.
Next day, observe how you glow and function at your personal best! You regained your brain! Read More
