Drinking energy drinks in the heat increases the risk of thrombosis, claims nutritionist Anastasia Lebedeva. The specialist warned about the consequences of using this drink, popular among teenagers, in warm weather.

“Only hot weather creates a load on the cardiovascular system: the pulse increases, blood vessels dilate, the body loses more fluids. Adding energy drinks during this period can worsen the situation - caffeine and stimulants (taurine, guarana) enhance the diuretic effect and increase blood pressure“, explained Lebedeva.

The nutritionist warned that caffeine and heat accelerate fluid loss, which leads to blood thickening and increases the risk of thrombosis. She reported that people with heart pathologies can experience attacks of tachycardia, especially with excessive consumption.

The combination with alcohol is doubly dangerous: energy drinks mask intoxication, but do not neutralize its effect, and the increased load on the heart can lead to a hypertensive crisis or collapse.

In the heat, the specialist recommends giving preference to water, isotonic drinks or green tea.

“If you are going to drink an energy drink, let it be no more than one can per day and only in the absence of chronic heart diseases. Mixing alcohol with an energy drink is strictly prohibited,“ she concluded.
