|A lot of people suffer from joint pain, stiffness and general achiness on cold, rainy, wintery days. There are theories to explain this and these include:
Lower Barometric Pressure – people with chronic pain may be more sensitive to lower barometric pressure. The theory is that this reduced pressure may irritate sensitised nerves and cause inflammation and swelling.
Reduced Blood Flow – when cold, your body conserves heat but pumping more blood to the lungs and heart. Less blood to your extremities means less incoming nutrition and waste removal from cells. The reduced blood flow also causes colder joints with thicker synovial fluid inside, creating stiffness.
Lack of Physical Activity – shorter, rainy days often mean more time spent indoors with less physical activity. Less activity means reduced blood flow around the body leading to stiffness and aching joints.
Poor Weather and Less Light Affects Mood – Barometric pressure changes can trigger low mood and induce headaches. We know that a low mood can enhance pain perception and this can spiral in winter months.
