The Risk Behind the Sun's Radiance

For many people, summer is a symbol of sea, vacation and outdoor activities. However, this pleasant period also brings with it some important health risks. Especially on days when heat waves increase, sunstroke (medically known as “heatstroke”) becomes a serious threat to public health. This often neglected condition is caused by a combination of factors such as not only high temperatures but also humidity, not drinking enough fluids and not wearing appropriate clothing. Especially infants, the elderly, people with chronic diseases and people who work outdoors are at the top of this risk group.

Physiology of Sunstroke: How Does the Body Respond?

The human body tries to keep its internal environment constant through a mechanism called homeostasis. Body temperature is an important part of this system and is usually maintained in the range of 36.5-37.5 °C. However, when exposed to the sun for long periods of time or working in high humidity, the sweating mechanism may not work sufficiently. Sweating is the body's main means of cooling itself, but as fluid loss increases, this system becomes inefficient and internal temperatures can reach dangerous levels. When the body temperature exceeds 40 °C, many organs, including the thermoregulation center in the brain, begin to be affected. This can start a chain reaction that can lead to unconsciousness, neurological damage and multiple organ failure.

Symptoms of Sunstroke: Early Diagnosis Saves Lives

Sunstroke is usually sudden and the symptoms are serious and should not be underestimated. Early symptoms include extreme weakness, dizziness, nausea and dizziness. However, as the condition progresses, serious symptoms such as high fever (40 °C and above), dry and flushed skin, inability to sweat, confusion, slurred speech, rapid breathing, muscle cramps or seizures occur. When these symptoms are recognized, medical intervention is required immediately. Left untreated, sunstroke can result in permanent brain damage, kidney failure and even death.

Who is more at risk?

Although sunstroke can occur in any individual, the risk is much higher in some groups. Especially infants and young children are more vulnerable to dehydration as their sweat glands are not sufficiently developed. In elderly people, the body's ability to cope with the heat is reduced as the body's heat regulation mechanisms are weakened. Individuals with chronic conditions such as diabetes, blood pressure and heart disease are also more sensitive to heat. In addition, outdoor workers in the construction, agriculture, road and logistics sectors and athletes who exercise heavily in hot weather are also in the risk group. In these groups, both individual awareness and environmental support are vital.

First Intervention Conscious Behavior Saves Lives

When symptoms of sunstroke are recognized, fast and effective intervention is extremely important. First of all, the person should be immediately removed from the sun and taken to a cool, airy environment. If the person is conscious, the body should be supported by giving fluids; however, if the person is unconscious, no oral fluids should be given. To cool the body, it may be effective to take a shower with cold water, apply ice packs or provide air flow with a fan. In the meantime, 112 emergency health services should be called and the person should be kept under observation until professional support is provided. Every minute delayed increases the health risk exponentially.

Ways to Avoid Sunstroke: Prevention is Better than Cure

Sunstroke can be largely prevented with simple precautions. It is important not to go out directly into the sun in the middle of the day (between 11:00-16:00), to stay in the shade, to wear loose and light-colored clothes, to wear a hat that protects the head from the sun and to wear glasses with UV filters. Water consumption should not be neglected throughout the day and excessive caffeinated and alcoholic beverages should be avoided. Physical activities in the sun should be avoided, and if possible, should be done early in the morning or in the cool of the evening. The use of sunscreen only protects the skin; it does not protect against sunstroke. Therefore, false perception of safety should be avoided.

Evaluation from an Occupational Health and Safety Perspective

Under Law No. 6331 on Occupational Health and Safety, it is a legal obligation for employers to conduct risk assessments and take necessary precautions against environmental factors such as heat stress that employees may be exposed to. In particular, personnel working in sectors such as construction, agriculture, tourism, logistics and energy should take more frequent breaks in hot weather, be provided with opportunities to cool off, and informative trainings should be organized. In addition, practices such as the use of personal protective equipment, water supply and first aid training should be standardized in workplaces. This is not only a legal obligation, but also an indication of the value the employer places on human health.

Respect the Sun, Prioritize Health

Sunstroke is one of the invisible but potentially fatal risks of summer. However, this risk can be largely controlled by individual awareness and institutional measures. Being prepared for the effects of hot weather in both daily life and business life is of great importance for both health and productivity. It should not be forgotten that every small precaution we take against the harmful effects of the sun can prevent major health problems. In order to protect our health, we should be conscious of the sun and always take our precautions one step ahead.
