The "dog days" of winter means more than bone-chilling cold weather and snow. Although people with seasonal allergy problems tend to favor this time of the year, perennial allergy sufferers and those with non-allergic rhinitis are currently singing the blues. What is it about mid-winter that brings on so many sinus complaints?
Here are some explanations:
-The changing weather fronts are associated with swings in temperature, barometric pressure and outdoor humidity. These atmospheric conditions may cause nasal congestion and postnasal drip (drainage down the throat) if you have allergic or non-allergic rhinitis .
-As we run our furnaces to keep our indoor areas warm the air inside becomes very dry. The sources of humidity from our bathrooms and kitchen (from cooking) are not enough to moisten the dry heat emanating from forced air heating vents or radiators. This means very dry air is inhaled through our nasal passages. Despite the ability of the nose to add liters of wa...
Why does sitting for long periods of time increase back pain sometimes? This question has been studied for the past 50 years and researchers still find controversy when trying to answer the question. At the heart of the dilemma is a mechanical dynamic between body weight, body posture, and spinal disc load.
A loading, compressive force on a spinal disc creates a certain amount of pressure within the disc which is like a marshmallow in between two graham crackers being squished together. This pressure can be measured with special devices inserted into the disc. With various body positions like lying down, sitting, standing and bending forward, the pressure amounts vary and were first reported in the landmark study performed by Dr. Nachemson in 1981 . In this study, he found that sitting produced higher pressures in the spinal disc than standing. So, for the past thirty years, clinicians have told patients with degenerative disc related back pain to avoid prolong sitting because h...
One of the most common problems seen in a primary care medical practice is low back pain. It accounts for more discomfort, lost work and productivity, and frustration for many patients than any other malady. Some think it is the price we, as humans, pay for walking upright. The lower back is a complex structure made of bone, muscles, connective tissue and nerves that, along with our legs, hold us erect, allow us to bend, run, twist, catch a football, or just lay down and rest. However, once a problem arises, the complexity of its structure makes pain in the lower back difficult to diagnose and treat. The lower back consists of a spinal column from the lumbar region of the mid-back down to the tail bone or coccyx. The spinal column consists of 5 lumbar vertebrae which are cylindrical bony structures with a ring like component behind the cylinder also made of bone. In between the vertebrae are disc shaped cushions filled with a gelatinous central core known as the nucleus pulposis
