People may frequently experience migraine headaches during the cold season, and patients with heart disease face the risk of heart attack. Oisana Makhmudova, a therapist at the Doctis telemedicine service, told socialbites.ca.
“Research shows that only one in ten people with chronic joint pain actually experience a worsening of their condition that coincides with a mild or moderate temperature change. It is believed that cold can change intra-articular fluid and make it more viscous, which can increase friction and pain. In reality, “To affect the fluid in the joints, there needs to be a sudden, powerful jump in pressure, like diving to the bottom of the ocean or climbing to the top of a mountain,” he explained.
However, according to the doctor, pain complaints increase in cold and rainy weather, especially in people with chronic joint diseases.
“Individual studies confirm a cause-effect relationship between these events. Other experts tend to believe that due to the general deterioration in mood, people begin to listen more carefully to their emotions, and this deterioration may also be associated with a decrease in activity and walking frequency,” he added.
Much more is known about the connection between colds and migraines.
“At low temperatures, receptors located in the head area can be overstimulated, causing headaches. In weather-dependent people, migraines can be caused not only by cold but also by other weather conditions: changes in atmospheric pressure, humidity, strong wind or temperature.”
The effect of cold weather on patients with chronic respiratory diseases also does not cause serious debate among scientists.
“Because cold air is quite dry, it further irritates the airways, causing swelling and increasing symptoms of asthma, bronchitis and chronic obstructive pulmonary disease. “Another reason is that the factors that cause bronchial asthma feel better in humid and cold environments,” emphasized the expert.
It is also not a misconception that cardiovascular diseases can worsen when the weather gets colder.
“In cold weather, blood becomes more viscous and it becomes harder for the heart to push it through the vessels. Moreover, the heart has to work harder to pump blood and thus keep our limbs warm. Increased heart rate and blood pressure can cause worsening symptoms in people, especially the elderly and those with chronic heart disease, including heart attack. This connection was proven by Japanese doctors who tracked the causes of cardiac arrest in 28 thousand people. “At first it was thought that the cause was humidity and pressure, but it turned out that the effect of cold was much stronger,” he said.
It is believed that the onset of a cold affects the decrease in immunity, and hypothermia leads to a cold, but this is not entirely true.
“Colds are not caused by hypothermia per se, but by viruses that develop and transmit more actively in the autumn-winter period. One of the reasons why the risk of contracting a viral disease is higher in the fall or winter than in the summer months is that people spend more time in a warm room and come into contact with people who are already sick. “And viruses are more stable in dry, cold weather,” he said.
In addition to its negative aspects, cold weather can also have positive effects on the body. Thus, the quality of sleep increases in winter, since the air more actively saturates the brain with oxygen.
“In winter, the brain also uses fewer resources to solve cognitive problems, concentrate and remember information. That is, in cold weather a person spends less effort to perform intellectual work, but gets the same high result as if he did it in the heat. Scientists are also studying whether the common cold is more likely to affect disease. “For example, a study of patients with amyotrophic lateral sclerosis (also known as Stephen Hawking disease) and Huntington’s disease showed that cold helps clear protein debris from body cells, which leads to these diseases.”
