Dr. Branislav Bogunovic, a cardiologist, points out that working outdoors in harsh weather conditions and engaging in intense physical exertion may increase the risk of stroke.
According to him, this includes in particular people who suffer from chronic diseases.
He says: "Prolonged exposure to heat outdoors leads to dehydration, which forces the body to constrict blood vessels to ensure blood flow to the brain."
He points out that under these circumstances, people with high blood pressure may experience even higher levels, and the effect may be reversed, especially among the elderly, where blood pressure levels decrease.
He says: "Strenuous physical work usually leads to high blood pressure. This is because during physical exertion, muscle tension causes blood vessels to constrict, which raises blood pressure."
According to him, these changes may be temporary, but over time they could lead to chronic diseases. The cold factor cannot be ruled out. Cold weather, like heat, contributes to high blood pressure, which is a major risk factor for stroke.
He says: "The first sign of a stroke may be loss of consciousness. One should also be aware if the person becomes unsteady—for example, if they do not understand speech, answer questions incoherently, or behave inappropriately."
Other telltale signs include a sudden feeling of weakness in the arm or leg, an inability to stand or walk, and facial disfigurement.
According to the specialist, the appearance of any of these symptoms in any case requires immediate medical attention.
