Medical Cannabis to fight against winter illnesses

winter illnesses maladies hivernales

When winter season is coming, many winter illnesses show up in our homes such us colds, cough and flu. Of course, there are basic techniques to avoid them: to adapt our diet to the temperatures, consume foods that contain minerals and vitamins, etc… However, all these techniques are not always effective.

Winter illnesses disturb our body and its homeostasis. Homeostasis is the ability of the body to maintain the internal balance, in other words, to preserve a good heartbeat, a good breathing, a good urination, sweating, digestion, body temperature, and blood composition. Given the fact that CBD helps regulate the Homeostasis, wouldn’t also be effective in fighting against winter diseases?

CBD for winter illnesses

Over the last few years, it has been proven that CBD strengthens our Immune System and so it can help fighting more efficiently against winter viruses. Indeed, the Endocannabinoid System and its main receptors CB1 and CB2 are present all over our body, especially within the Immune System.

Most of the studies being done in the last few years, about the influence of CBD on the Immune System, indicated that cannabinoids can modulate the function of the T and B lymphocytes, and NK cells and macrophages, which allows the body to fight against these viruses that come to attack our Immune System.

Winter diseases can also bring fever outbreaks, and this can nail us in bed for a whole day. The aim is to prevent dehydration by keeping a low temperature and by maintaining the level of several body fluids.

Cannabinoids also have a role to play in the decrease of body temperature and so, they can help to lower the fever. Studies have demonstrated that Tetrahydrocannabinol (THC) could provoke a phenomenon called “Induced Hypothermia”. The components of THC can trigger the receptor TRPA-1, which has the function to control pain, inflammation and temperature regulation. In the 80’, studies were carried out on rodents and the researchers succeeded in finding a correlation between cannabis consumption and a decrease in body temperature.

These several studies carried out over the last years have shown that cannabinoids can be an effective cure against winter illnesses.
