Colds and Flu

Cold and Flu Prevention

Cold and Flu Prevention

Flu season generally begins in November- December and can last until May . Every year concerns are raised about new strains and the risk to elderly or immunocompromised people. But it's not just the extra vulnerable among us whom colds and flus impact. None of us enjoy being sick, missing work, and experiencing muscle aches, fever, and chills. There are many ways we can boost our immune systems to prepare for changes in the weather and circumstances that start the spread of communicable diseases.

Relieve Sinus Congestion Through Acupuncture

Relieve Sinus Congestion Through Acupuncture

Sinus congestion is one of the most common ailments that is mentioned during acupuncture appointments. It often comes up as a secondary complaint, but after applying needles to a few key points I hear about immediate benefits in ability to smell and breathe through the nose. Let’s explore how those needles work.

Vitamin C, Zinc or Vitamin D ?


The answer might surprise you...


Vitamin DCan vitamin C supplements help you avoid colds and flu this  season? In a word, no.  Clinical trials of approximately 10,000 participants, have failed to find that vitamin C supplements decreases the risk of catching cold or flu in ordinary people.  However, they did determine it might at least shorten the length of a cold.



Vitamin C is essential in your diet so your body can form collagen in bones, cartilage, muscle, and blood vessels.  Vitamin C helps maintain healthy teeth and gums, and helps wounds heal. The best way to increase your vitamin C intake is to eat plenty of fruits and vegetables, such as green or red peppers, kiwi, oranges, melon, and broccoli.


Zinc is another nutrient that has not lived up to its promise of preventing colds. Experts disagree about whether  zinc lozenges might shorten the duration of a cold,  If you decide to try  using zinc to make your cold end sooner, you should know that gels or sprays that apply zinc to the inside of the nose should NOT be used. They have been taken off the market after many consumers reported losing their sense of smell.  To boost your intake of zinc naturally, choose rich food sources such as beef, poultry, legumes, whole grains, nuts and seeds.


The most promising single nutrient in the quest to prevent colds and flu is vitamin D. Several studies have shown that vitamin D deficiency is linked with more colds and flu. It is too soon to know if taking vitamin D supplements can help prevent these upper respiratory infections. Still, people living in Maine may want to consider taking a vitamin D supplement. Unlike other nutrients, which can be consumed in food, your body must manufacture its own vitamin D; this only happens after you bare skin is exposed to strong sunlight. Since that is unlikely to happen during the fall, winter and spring at our latitude, a vitamin D supplement may be in order. Although the outdated Institute of Medicine guidelines still call for 400 IUs of Vitamin D per day for adults, most experts now agree that 1000 IU per day is probably closer to meeting the needs of most people. If you have a documented vitamin D deficiency, you may need even more vitamin D, but higher doses should only be consumed under the supervision of your health care provider.
