The extreme heat, which is increasing its impact across the country, draws attention not only with its oppressive weather but also with the health threats it brings along. Experts warn particularly about the risk of thermal shock for patients with heart and blood pressure issues, as well as the elderly. Protecting the body from sudden temperature changes is possible with simple yet vital precautions.
Recently, the extreme heat wave affecting the country has once again brought the risk of 'thermal shock' to the forefront. Thermal shock, caused by sudden temperature changes, can pose a life-threatening risk, especially for individuals with heart, vascular, and respiratory conditions.
HOW DOES THERMAL SHOCK OCCUR?
The physiological stress and response that the body experiences due to sudden temperature changes is defined as 'thermal shock'. It particularly occurs when transitioning suddenly from a very hot environment to a very cold one (or vice versa). For example, a person sweating under the sun at 40 degrees suddenly taking a cold shower or stepping outside from an air-conditioned environment, resulting in the body reacting abruptly, are live examples of thermal shock.
WHAT HAPPENS IN THE BODY?
During thermal shock; blood vessels suddenly constrict and dilate, disrupting blood pressure balance. Heart rhythm can change rapidly, increasing the risk of heart attack. Body temperature cannot be regulated, excessive sweating, shivering, and even loss of consciousness may occur. The immune system can be suppressed, making one susceptible to colds and infections.
WHO IS AT GREATER RISK?
According to experts, individuals most at risk from 'thermal shock' are those with heart and blood pressure conditions. In addition to this group, the elderly and infants, diabetics, outdoor workers, and especially individuals exercising and playing sports outside during the summer months are also at risk.
WARNING FROM EXPERTS: GRADUAL TRANSITION IS ESSENTIAL
Simple yet effective measures can be taken to protect the human body from thermal shock and reduce its possible effects. Gradual transition is one of these measures. According to experts, when transitioning to hot or cold environments, the body needs time to adjust. For example, instead of suddenly jumping into ice-cold water after leaving a sauna, take a warm shower to balance body temperature. Similarly, on an extremely hot day, it may be beneficial to wait outside a bit before entering an air-conditioned room.
HOW CAN WE PROTECT OURSELVES?
One of the primary methods recommended by experts to prevent thermal shock is adequate fluid intake. Especially in hot weather, drinking plenty of water helps the body cool down through sweating and prevents dehydration. Dressing appropriately for weather conditions also facilitates easier adaptation to temperature changes.
Additionally, it is advised not to jump directly into cold water after being in extremely hot environments and to adjust the temperature difference between the air conditioning and the outside environment to not exceed 8 degrees as protective measures.
