The days are long, the temperatures have peaked – summer is here. Almost all of Germany more than 30 degrees this week. What needs to be considered in this heat in order to protect the circulation, explains Dr. med. Michael Schneider, Chief Physician of the Central Emergency Department (ZNA) at the RHÖN-KLINIKUM Campus Bad Neustadt.
Heart and circulation
Even healthy people complain of fatigue and circulatory problems in this heat. In chronic heart patients or patients with high blood pressure, the blood pressure can drop sharply, as the vessels widen due to the heat. Circulatory collapse and cardiac arrhythmias threaten.
The hot weather poses a particular danger for the elderly and those with heart disease. Older people in particular often do not drink enough to keep their bodies hydrated, even on hot days. Dehydration occurs. “It manifests itself in symptoms such as headaches, lack of concentration, circulatory disorders and dry skin.” Michael Schneider, Chief Physician of the Central Emergency Department (ZNA) at the RHÖN-KLINIKUM Campus Bad Neustadt.
When patients with these symptoms arrive at the ZNA on campus, the first goal of the doctors and nurses is to regulate the electrolyte balance that has been disturbed by the lack of fluids. This is usually done via an infusion that, together with fluid, also supplies the body with minerals such as sodium or calcium.
Drinking is the be-all and end-all
In very hot weather, the body can lose one to two liters of fluids and electrolytes every day through sweating. In order to prevent circulatory problems, the chief doctor recommends that you drink enough. It should be two to three liters when it is hot. Water, juice spritzers, and unsweetened teas are best for this. But fruits and vegetables can also help to keep the body’s own water balance stable. In order not to forget to drink, you should always have a bottle of water with you when you are out and about and drink something regularly with meals.
Gardening in the blazing sun and top sporting performance should be avoided for the sake of health on hot days. The cooler morning and evening hours are also more suitable for sporting activities. He recommends staying in the shade or in buildings during the greatest heat of the day; elderly people and patients with cardiac insufficiency should take some physical care.
