High temperatures are threatening people who stay outdoors at midday, who do not hydrate enough and who are suffering from cardiovascular disease. Hypertension, heart disease or other associated ailments are aggravated by high temperatures during summer.
Summer is a difficult season for people suffering from hypertension. Monitoring and drug dosage adjustment are essential for these patients.
Sweating and peripheral vasodilation causes a decrease in blood pressure. In this case, the effects correlated with antihypertensive drugs lead to dizziness and even fainting.
Doctors recommend people suffering from hypertension to control their blood pressure regularly, to go to the doctor if adjustment in the medication dose is required, to hydrate and avoid walking in the heat hours.
The risk of stroke is increased in summer
Dehydration due to excessive sweating at a high temperature is a major risk factor for patients with cardiovascular diseases.
Dehydration is manifested by tiredness, muscle cramps. When there is no longer enough liquid in order for the blood to circulate normally, the organism may go into shock.
On the other hand, those most at risk of a stroke in summer are those who work outdoors or traveling, spending so many hours in high temperatures.
The main symptoms in this case are increased body temperature, persistent headache, rapid heartbeat, and installing state of delirium.
Prolonged exposure to the sun can lead to vision loss
Individuals who spend too much time in the sun are at risk of eye diseases, experts warn. Studies show that young people who have spent a lot of time in the hot sun during summer are twice as likely to develop macular degeneration in later years.
This condition occurs when the retina begins to deteriorate and fail to properly capture images. Macular degeneration is the leading cause of vision loss in older people.
The sun increases the levels of anxiety
Experts believe that the symptoms of heat discomfort can be similar to anxiety. The presence of these symptoms, dizziness, palpitations or rapid heart rate, can trigger an anxiety attack.
