Why do you catch cold in summer?

The Covid-19 pandemic has overshadowed many winter viruses (rhinovirus and influenza in the lead). Despite the increase in temperatures, they can resurface in summer for several reasons:

The lifting of barrier gestures

The resurgence of winter viruses is explained in part by the gradual lifting of certain barrier gestures, particularly wearing a mask outdoors. The return to a dynamic social life (multiplication of large concentrations and festive events, more crowded public places, etc.) also causes a certain promiscuityconducive to the spread of viruses.

A less efficient immune system

With the winter of 2021 being placed under the sign of Covid-19, our immune system, previously trained to fight winter viruses and to deal with many pathogens, has gone several months without being exposed to them. Therefore, he lacks training and could then they need more time to reactivate against the simple viruses responsible for nasopharyngitis.

“Frequent exposure to various pathogens primes or stimulates the immune system to be ready to respond to that pathogen,” said Dr. Paul Skolnik, an immunovirologist and chair of internal medicine at the Virginia Tech Carilion School of Medicine (United States), in New York Times (source 1). And to continue: “If you haven’t had these exposures, your immune system may be a little slower to react or not respond as fully, which leads to increased susceptibility to certain respiratory infections and sometimes longer or more prolonged symptoms“.

Annotate : the stress it can also trigger a drop in immune defenses, hence, a more acute sensitivity to cold viruses.

Summer cold: blame the air conditioning?

The use of air conditioning systems and fans. during the summer period it can also be the cause of a summer cold. Significant changes in temperature cause heating of the mucous membranes: blood vessels dilate when it is hot, and constrict when it is cold. When suddenly going from a cool environment to a cold environment, the contraction and expansion phases they multiply and we become more susceptible to viruses.

Not to mention the fact that Air conditioning systems spread viruses. in all rooms.

The common cold usually disappears spontaneously: the virus is eliminated naturally by the body. Some medications can relieve uncomfortable symptoms:

  • Paracetamol relieves fever and headaches.
  • Nonsteroidal anti-inflammatory drugs, such as ibuprofen and aspirin, should not be used without medical advice: they are not recommended for pregnant women and contraindicated from the sixth month of pregnancy.
