Do We Really Get Sick More Often During the Winter?

Do We Really Get Sick More Often During the Winter?

i`m ill seriesAlthough your mother may have admonished you when you to bundle up when you went outside during the winter to avoid getting a cold, science shows that this advice is actually pretty ineffective. While it seems to be true that people tend to get sick more often during winter, it has nothing to do with getting a chill. Scientists do have a few alternative explanations for this phenomenon.

First of all, we tend to spend a lot more time indoors when it’s cold outside. Germs are spread far more easily in a crowd or within enclosed spaces. The more people in an enclosed space with a sick person, the more people with an opportunity to become infected. However, this doesn’t explain why children in crowded classrooms get sick more often during winter months, even when the number of students present in the classroom may not change much (or at all) from season to season.

One aspect of winter conditions is that the air is colder and drier. Dry air dehydrates our nasal passages and makes it more difficult for the mucus membranes in our respiratory system to trap and sweep away pathogens, which it typically does more effectively in a warmer, more humid environment. This is one reason why travelers often become ill after enduring a long plane flight– the atmosphere of the cabin is very dry. Add this to the combination we talked about before (lots of people in an enclosed space for a prolonged period of time), and it’s easy to see why a cold virus or flu virus would have a much easier time infecting more individuals in this sort of situation.

In addition, a study has shown that the flu virus in particular survives far longer in cool, dry conditions than in warm ones. Peter Palese and colleagues at the Mount Sinai School of Medicine in New York conducted an experiment on guinea pigs. They found that when guinea pigs were exposed to the flu virus they infected each other quite easily in cool, dry air, but when the temperature was 86°F the guinea pigs could not infect one another at all.

Another theory advanced by some scientists is that in winter our bodies are often low in stores of vitamin D due to a lack of sunlight. Vitamin D deficiency has been shown to cause a reduction in immunity. Given that much of the population in the developed world lives at latitudes where even direct sun is often weak in winter and that these same people are more likely to use sunscreen, it’s not surprising that many don’t have enough vitamin D. Studies show that flu season in different parts of the world correlates with cold weather and short hours of daylight. In the northern hemisphere, cold and flu season runs from November to March, and in the southern hemisphere from May to September. Meanwhile, the tropics have no cold and flu season at all.

Another contributor to a lowered immune system is sugar intake. Around the holidays, people not only find themselves gathering in large groups more frequently (think about office festivities, family celebrations, crowded shopping malls, etc.), but there are also more sweets to be had, which also works to suppress our immune system.

According to health experts, the best thing you can do to avoid winter colds and flu is to wash your hands frequently, since germ-covered hands are the most common way we infect ourselves. It’s not necessary to keep your house at tropical temperatures, but a humidifier may help reduce the drying out of your respiratory passages. Finally, taking a vitamin D supplement and keeping the sweets to a minimum may help reduce the number of times you get sick each year.

We are bombarded daily with all sorts of microbes that can cause illness. Interestingly, if we are exposed to a wide range of these microbes as children, studies have shown that we will have a lower risk of asthma and allergies as well as a stronger immune system. There are a number of factors that influence the health of our immune system, including diet, stress, exercise and aging. Following are some strategies you can use to help strengthen your immune system.

Eat plenty of fruits and vegetables – These are high in the vitamins, minerals and trace elements you need to help keep you healthy, particularly those high in vitamin C (red bell peppers, strawberries, broccoli, citrus fruits) and zinc (nuts, seeds, wheat germ).

Reduce stress – Chronic stress has been shown to inhibit the production of interleukins and cytokines, which are responsible for stimulating the action of white blood cells. Chronic stress also causes the stress hormone cortisol to be continually released into the bloodstream, which in the long term suppresses the production of pathogen-fighting T cells and antibodies.

Get out in the sun – Insufficient vitamin D has been linked to greater susceptibility to infection. Approximately one out of three Americans is deficient in vitamin D. Try to get out in the sun in the summer months wearing minimal clothing and no sunscreen for 5 to 10 minutes two or three times a week between the hours of 10 am and 3 pm. This will provide you with sufficient vitamin D without increasing your risk of skin cancer. You can also take a supplement in the winter months or if you live in a place without much sun.

Get sufficient sleep – Sleep deprivation increases inflammation and inhibits the immune response. One study found that people who habitually slept less than seven hours each night were nearly three times more likely to catch a cold than people who slept eight hours or more.

Exercise – Moderate exercise has been shown to decrease stress and boost the immune system. Thirty minutes of moderate exercise each day, such as a brisk walk, raises the body’s levels of leukocytes, which are cells that help guard against infection.

Eat probiotics – Perhaps even more important than antibiotics in the fight against infection are probiotics, beneficial bacteria that live in the gut and upper respiratory tract. They boost the immune system by encouraging the production of certain T cells. You can find probiotics in yogurt, sauerkraut and kimchi, or you can take a probiotic supplement.

Avoid sugar – Even 100 grams of sugar, the equivalent of a 24-oz soda, depresses your immune system by reducing the ability of white blood cells to combat bacteria. This effect can last for a few hours after sugar ingestion, so if you are trying to stay healthy, keep away from the sweets!

The Power of Gratitude on Health

The Power of Gratitude on Health

How we think and how we process the world around us has a tremendous effect on our health and our happiness. In celebration of this time of Thanksgiving, take some time out for yourself and contemplate all the many things that you have to be grateful for. If you find the task difficult, keep at it – it will get easier. Then, make it a daily habit – you will never be sorry that you decided to make gratitude a daily part of your life!

Here's How Gratitude Affects The Human Body:

The Power of Gratitude

The Power of Gratitude

Water crystals

 

Research done by Japanese scientist Dr. Masaru Emoto with water crystals is fascinating but his research teaches some important health lessons as well. Dr. Emoto has studied the effects of positive energy and negative energy on water. Some of his research has included music and some of his research has included messages given to water. What does that have to do with us – with you and me? Our bodies are 70-80% water. So what holds true for water also holds true for us. For example, Dr. Emoto and his colleagues found that water droplets would form widely different crystalline patterns after being exposed to different kinds of music. Exposure to acid rock would result in a very disrupted crystal while a Mozart symphony would result in a beautifully formed crystal. Below, we have included a blog post written by Dr. Sabrina Chen-See written about Dr. Emoto’s work as well. We hope you will read her blog post and then think about what you are surrounding yourself and your life with and what affect your attitude and gratitude can have on your health. If you would like to learn more about Dr. Emoto’s work, you can read his book Hidden Messages in Water.

Want to know the secret to changing your mental state, your luck, your future and life for the better? It’s simple… it’s by expressing gratitude.

As seen in Dr. Masaru Emoto’s water crystal research, exposing distilled water to the words “Thank You” overnight resulted in a physical change to how the molecules behave. Water exposed to positive words like, “Love”, “Kindness”, “Peace” and “Joy” formed beautiful, intricate snowflake-like water crystals. When exposed to negative words like, “I will kill you”, “War” and “Stupid”, the water crystals would be dark, asymmetrical, ugly blobs.

Gratitude has incredible healing properties. Microwaved water will not form crystals. However, after being blessed, it will then form beautiful crystals. This is scientific proof that the energy of our food is better in meals that are made from scratch with love and in meals that are blessed before consumption. Dr. Emoto concluded the first round of research with this summary:

“If thoughts can do this to water, and we’re 70-80% water, then what is the effect of thoughts on us?”

How do you harness this power of gratitude and channel this power into transforming your life? For lasting change, consider starting a gratitude journal. My gratitude journal is a pocket book with pretty designs throughout. Each morning, write a positive affirmation or quote for the day, such as:

“Always end the day with a positive thought.”

“No matter how hard things were, tomorrow is a fresh opportunity to make it better.”

As the quote says, end the day with something positive. In the gratitude journal, write out 5 things you are grateful for, or something/someone you love. The last thoughts you have before falling asleep repeat themselves 20, 000 to 40, 000 times per night. Journaling like this can make changes to your outlook immediately, and lets the universe know that you are open to abundance. Keep it up for 30 days to ingrain it as a daily habit and continue the rest of your life for ongoing healing of your mind, body and spirit.

To supercharge the power of gratitude, you must take action and show your gratitude each and every day. I’m not talking about making a show of gratitude for recognition. I’m talking about letting the source of what you’re grateful for knowing that they are appreciated, and supporting their efforts. If someone was kind to you, thank them directly. Written thanks (ever notice pretty “Thank You” cards?) are more lasting than a verbal “thanks”. If it was a stranger you’ll never see again, pay it forward with a kindness to another stranger. If you’re grateful for a beautiful sunset or clean air, do what you can to support our environment, to preserve or improve it for future generations. If you’re grateful for your wife/mother preparing meals for you each and every day, support her by setting the table, washing dishes, etc. The key is to help out because you’re grateful, not because you’re obliged to do it. If you’re going through health challenges, you can still be grateful for all your body is doing to heal itself. Support your body by loving it, feeding it good food, resting, chiropractic care, exercising and positive thoughts. If you’ve been blessed with talents and special gifts, show your gratitude by developing them and using them for the betterment of yourself, your family, society, humankind and the planet. – Dr. Sabrina Chen-See

Have a Cold? Top Ten Tips for Getting Better Faster

Have a Cold? Top Ten Tips for Getting Better Faster

Oh No! Sick Man Checking for a FeverThe common cold: Even though Americans have over a billion colds per year, there’s nothing “common” about it when you’ve got one. The sneezing, the scratchy throat, the runny nose, the nasal congestion, and the watery eyes can make your life miserable. Even though most colds go away within three to seven days, there are steps you can take to boost your body’s immune system and help get rid of your cold sooner than that. Read on for our “Top 10 Tips” on getting over your cold quickly, consolidated from healthcare experts all over the world.

  1. First, make sure you’ve really got a cold. The symptoms listed above are those of the common cold, which is a disease of the upper respiratory tract caused by a number of different viruses. But if these symptoms are accompanied by more severe ones such as muscle aches, high fever, chills, headache, and fatigue, chances may be that it’s not a cold at all, but the flu instead. This is important to find out, because if you have a serious case of the flu, you may need to see a doctor and take an antiviral medication like Tamiflu, which can shorten the length of the outbreak. However, if you’ve got a cold, not only will the antiviral medication be ineffective, it can even weaken your immune system in the long run.
  2. Don’t “tough it out”—stay at home and get some rest. Going to work will only make your cold last longer, and you can expose all your coworkers to the virus as well. So take a few days off and give your body the rest it needs to recover and heal faster.
  3. Drink lots and lots of liquids, including—yes, really—chicken soup. Your mother’s advice to drink lots of fluids was correct, as it turns out. Research has shown that drinking warm fluids helps to relieve the most common cold symptoms and also loosens sinus secretions that cause a buildup of mucus. Hot tea or broth is a good choice, as is coffee, which has been shown to increase alertness in people with colds. And interestingly enough, the centuries-old prescription to “Have a nice bowl of chicken soup.” is also correct—it has been shown to be more hydrating and thus more beneficial than other liquids.
  4. Gargle with salt water. Gargling with 1/2 teaspoon of salt dissolved in 8 ounces of water can help to relieve your sore or scratchy throat.
  5. Use over-the-counter medications (very selectively) to deal with runny nose and coughs. A pharmacy has reliable saline nose drops or sprays and cough syrups that can help to make these cold symptoms more bearable, although they won’t make the cold go away any faster.
  6. Steam the cold away. If you have access to a steam bath, take one—or many. If you don’t, you can improvise by leaning your head over a bowl of hot water or by taking a long, steamy shower. Inhaling warm, moist air helps to loosen and thin out mucus.
  7. Boost your immune system with supplements. Research has shown that taking zinc supplements during the first couple of days may help shorten the duration of your cold and perhaps reduce its severity. But don’t take zinc on an empty stomach, and don’t use intranasal zinc nose drops or sprays; the FDA has warned that they can permanently impair your sense of smell. Vitamin C can also help to shorten colds, whether in supplement form or in fruits and vegetables. Echinacea, elderberry syrup, and raw honey have also been shown to shorten colds.
  8. Avoid smoke and polluted air. Anything that affects your ability to breathe properly is going to extend your cold.
  9. Don’t reinfect yourself or others. Practice “safe sneezing and coughing” by covering your nose and mouth and carefully discarding any tissues you use. Wash your hands often and consider using hand sanitizers to keep from infecting family, friends, coworkers, and yes, even yourself. If you contracted the cold at work and others there still have their colds, avoid the place for a few days if you can until people get better.
  1. Use over-the-counter pain relievers to reduce inflammation. Used in moderation, aspirin, acetaminophen, ibuprofen, and naproxen can all help relieve minor bodily aches that may accompany your cold, but they also act as anti-inflammatories and can reduce a fever and speed up the healing process.
Superfoods: Science or Marketing?

Superfoods: Science or Marketing?

Breakfast Cereal 3There is no medical definition for a “superfood”. Food manufacturers are eager to use the word to promote sales of their products that contain traces of supposed superfoods such as blueberries, pomegranates and chocolate. The Oxford English Dictionary defines a superfood as “a nutrient-rich food considered to be especially beneficial for health and well-being.” However, there are no set criteria about what makes a food nutrient-rich. Most superfoods are high in antioxidants and phytonutrients relative to other foods. However, if you were to eat only one of these superfoods to the exclusion of all else, you would be seriously deficient in many of the nutrients your body needs in order to stay healthy. So what exactly is the science behind the idea of superfoods?

While we would like to believe that if we eat certain foods we can stave off illness and keep aging at bay, the truth is that it’s not so easy. Although there is no doubt that a diet consisting primarily of fruits and vegetables is one of the keys to healthy longevity, it is also what you don’t eat and do that is important. For instance, if you eat a breakfast of blueberries and pomegranates in a bowl of oatmeal, along with a cup of green tea, that does not mean that your health will improve overall if for lunch you have a bucket of fried chicken, French fries and a 64-ounce Coke, followed by a cigarette.

The majority of scientific studies indicating that there may be some positive health effects associated with the nutrients contained in certain foods were conducted in a laboratory. In general, high levels of nutrients are used in these studies—usually far more than what can be consumed in a normal diet. For instance, the compound resveratrol that studies have shown to be heart-healthy and to guard against prostate cancer is found in grape skins only in very small amounts. So although “the French paradox” (why the French have low rates of heart disease despite a rich diet) is often partially attributed to the regular consumption of red wine, in fact, you would have to drink 40 liters of wine a day to get the same amount that was shown to benefit the health of mice in these studies.

The positive results of studies performed in test tubes on a few human cells and studies performed on mice do not necessarily translate into health benefits for the wider population. The effect of a single nutrient on human health is difficult to pinpoint, as we all eat a combination of foods. Some nutritional benefits may only occur in the presence of other nutrients in the same food, or even in a different food eaten at the same time. Iron absorption, for example, is boosted when a food rich in vitamin C is eaten at the same time.

The best nutritional advice someone can follow if they’re interested in maintaining good health is to eat a wide range of whole foods, and (even more importantly) to avoid foods that are bad for you such as processed foods and hydrogenated oils. As the European Food Information Council advises, “A diet based on a variety of nutritious foods, including plenty of fruits and vegetables, remains the best way to ensure a balanced nutrient intake for optimal health.”

 

Benefits of Zinc

Benefits of Zinc

Muscular body builderZinc is the second-most common mineral in the human body (after iron) and is found in every one of our cells. It plays a vital role in many of the body’s functions, so ensuring that you get enough zinc in your diet is important. It is essential for helping the body to heal and for the maintenance of a healthy immune system. It is also important is supporting the senses (taste, sight and smell), blood clotting and healthy thyroid function.

Zinc is one of the most important minerals for fertility and general reproductive health. It is necessary for proper levels of testosterone in men and the maintenance of a healthy libido. The mineral also plays a key role in the healthy development of sperm, and abundant levels of zinc have been shown to be protective of the prostate, reducing the risk of prostate cancer. The belief that oysters have aphrodisiac properties actually does have some basis in truth. Oysters have one of the highest concentrations of zinc of any food. In women it regulates estrogen and progesterone and supports the proper maturation of the egg in preparation for fertilization.

Ensuring you have an adequate level of zinc can help reduce your risk of insulin sensitivity, one of the precursors to diabetes. It supports T-cell function, which boosts the immune system when the body is under attack by bacteria and viruses.

Zinc deficiency is not common in the developed world, but those with anorexia, alcoholics, the elderly and anyone with a malabsorption syndrome such as celiac disease or Crohn’s disease is at higher risk. Zinc deficiency symptoms include frequent colds, poor wound healing, poor growth, loss of appetite, weight loss, dermatitis, psoriasis, hair loss, white spots on the nails, night blindness and depression.

Following is the recommended daily intake of zinc for different age groups:

Infants birth – 6 months: 2 mg/day

Infants 7 – 12 months: 3 mg/day

Children 1 – 3 years: 3 mg/day

Children 4 – 8 years: 5 mg/day

Children 9 – 13 years: 8 mg/day

Adolescent boys 14 – 18 years: 11 mg/day

Adolescent girls 14 – 18 years: 9 mg/day

Men 19 years and older: 11 mg/day

Women 19 years and older: 8 mg/day

Pregnant women 14 – 18 years: 12 mg/day

Pregnant women 19 years and older: 11 mg/day

Breastfeeding women 14 – 18 years: 13 mg/day

Breastfeeding women over 18 years: 12 mg/day

Children should never be given zinc supplements without first consulting with a pediatrician. If supplements are necessary, a copper supplement should be taken as well, as a high intake of zinc can deplete levels of copper.

You should be able to get adequate zinc from eating a healthy, balanced diet rich in whole foods. The body absorbs between 20% and 40% of the zinc present in food. The best sources of zinc are oysters, red meat, poultry, fish, shellfish, cheese, legumes (such as soybeans, black-eyed peas and peanuts), cooked greens and seeds (such as pumpkin and sunflower).

Remember that Zinc is especially important for the winter months!
