Why Cold Baths Boost Your Immune System and Slim You Down: So, Cold Baths, Anyone?
Since December last year, mornings have been getting colder in Metro Manila. This January is worse--almost the whole day gets cold. And they say it will be even worse as we approach the first week of February and during. So what do we do? Naturally, most of us boil water to mix with a pail of cold water.

Well, some researches say we may be forfeiting ourselves of immune boosts whenever we prefer warm baths to cold ones. I admit that I'm among those who can't stand freezing water during cold days, especially early in the morning or in the evening. I must boil water. But I remedy this--after completing my (a bit of a) warm bath, I pour 4 to 5 dippers of cold water on me to conclude it. That gives me a bit of an immune boost. But then, that's no substitute for a cold bath.

Here are the health benefits of cold showers or baths, according to The Hacked Mind site (by Mans Denton):

  • Better Blood Circulation - blood automatically flows more to your body organs to keep them warm when you feel cold. So, that triggers blood circulation. Warm water makes most of your blood stay on the skin areas.
  • Better Mood - cold baths or showers trigger noradrenaline in the brain which is responsible for getting better moods.
  • Better Immune Health - experts say you get higher levels of white blood cells (necessary for fighting infections), T-cells, plasma, and lymphocytes. 
  • Better Testosterone Levels - you need high testosterone levels to develop height and muscles during puberty stage and maintain bone and muscle strength during adulthood. Add to that, better sex life and increased sperm count for the testes [LiveStrong.Com].
  • Increased Metabolic Rate - yup, cold showers increase your metabolism and that helps you lose weight more. When your body feels cold, your metabolism adjusts body temperature regulation and that involves lots of calorie burning. So, weight loss enthusiasts, what are you waiting for?
Watch what an experiment on immune boost through cold baths has to say, published at the NCBI site: "This paper hypothesizes that brief cold-water stress repeated daily over many months could enhance anti-tumor immunity and improve survival rate of a non-lymphoid cancer." However, the study also warns that, though cold hydrotherapy can alleviate physical pain, cold baths may trigger heart palpitations or arrhythmia in heart patients and cold immersions may cause pulmonary edema. Moreover, cold baths may "increase permeability of the blood-brain barrier, thereby increasing mortality of neurovirulent infections."

Thus, now and then I get a bit more adventurous and brave a cold bath--but with precautions--with a ready thick towel and jacket on standby, plus a hot cup of water, just in case. Chilling can disrupt your breathing that sometimes causes pain in the chest area, making you think you're about to have an attack. But concentrate and make yourself breathe normally (a bit slow) and deep, so there's enough oxygen in the body and brain. It's healthy for the lungs, anyway--the deep breathing.

And once a thick towel and jacket is wrapped round your body, everything goes back to normal in no time.

Ice bucket challenge? Not necessary and not recommended. Just take a cold shower in your bathroom.

Harvard Study Says Chicken Skin is Healthy!

You used to take off chicken skin because doctors and nutritionists said it's bad for your heart. So, with broken hearts we did so, stripping the golden brown and juicy skin from our roasted or grilled chicken and couldn't believe we were actually throwing away all that goodness into the trash.

And we wondered why God made chicken skin so delicious just so we could throw it all away.

But a new Harvard study says chicken skin is actually good for your health---to be specific, your heart health. It says most of the fatty part of chicken skin (the most mouthwatering one) is unsaturated and healthy for the heart. And that's according to studies done by the Harvard School of Public Health, no less.

Unsaturated fat can lower your cholesterol and blood pressure, the Harvard school said, according to an article on The Daily Meal site titled "Doctor's Got It All Wrong!" So, if the study is correct (I'm waiting for another "study" to contradict this---al…

Do You Know the Right Way of Eating Fruits 2

Previously on Right Way of Eating Fruits

Another mistake people do when eating fruits is eating them long after peeling their skin. Not many people know this, but all fresh fruits are alkaline, even soir ones. I met one "nutritionist" who thought sour fruits were all purely acidic---just because they were sour.

Take kalamansi for instance. Fresh kalamansi is alkaline. Those who know herbal medicine know this. But make sure you consume it right after slicing it open. If you let it lie open like that for a long time it becomes acidic. Moreover, the Vitamin C in it quickly evaporates. You get nothing but sourness.

So those fruit juices sold in bottles in grocries and malls? You get nothing from them except water, flavor, sugar and synthetic Vitamin C perhaps, which is acidic. If you want to keep fit, an acidic tummy is the last thing you'd want.

Here are my secrets on how I get physically fit. Click here.

If you peel off a banana, make sure you eat the whole thing now. Don&#…

How Posture Affects Your Confidence Level

Try it. Make it a habit to stand erect---chest out, stomach in---and make sure you look relaxed and natural doing it. No hint of struggling. How? Well, keep practicing this posture.

And then always lift your chin and look straight ahead with relaxed, rested eyes. Even if you don't feel confident inside, that look will make people think you have it. That look and posture often earn you respect.

Now, when you see people awed at you because they think you have powerful self confidence---when in fact you don't---you begin to feel confident. It builds up like a miracle.

I tried it once. I used to stand up with stooping shoulders and often looking down at the floor. Then one time I saw how it looked in a mirror. Such a look of defeat and weakness. Then I wondered---does good posture really make a difference?

So I started practicing good posture. I studied how to stand, sit and walk erect, like a real model. I watched how models moved and imitated them. Together with my regular work…
