Stroke and myocardial infarction, which strike without warning, and cancer and diabetes, which progress silently, are fatal diseases that threaten the health of modern people.
Dr. Choi Seok-jae, an emergency medicine specialist who has saved countless lives in the emergency room for 19 years, says this crisis is the result of missing signals from the body for a long time.
"30 Last Signals Your Body Sends" focuses on how to identify disease "signals" early and respond within the golden time.
It emphasizes the importance of habits that address the root causes of illness, not just simple first aid measures.
This book is a practical guide to creating a virtuous cycle of health through awareness, connection, and action.

The scariest thing is something else.
As soon as a myocardial infarction occurs, the heart muscle trembles and falls into 'ventricular fibrillation', which is when the heart loses its pumping function of sending blood to the whole body.
Because blood flow to the brain is cut off, brain cell damage begins after just one minute.
After 4 minutes, irreversible brain damage occurs.
If CPR is not performed immediately, the mortality rate increases by 10% for every minute.

The golden time for myocardial infarction is ‘within 2 hours’ after symptoms occur.
It is best to arrive at an emergency room capable of cardiovascular intervention within 'one hour' of symptom onset.
Because it takes time to call the on-call surgical team while preparing for emergency surgery.
Permanent damage to the heart muscle can be minimized if coronary angioplasty is performed within 2 hours of symptom onset.
Naturally, the shorter the time, the higher the survival rate and the better the prognosis.

High blood pressure is the biggest risk factor for cerebrovascular disease, but it is often called the "silent killer" because it has no symptoms.
Many patients say, “I didn’t know I had high blood pressure; I had no symptoms.”
However, high blood pressure puts excessive pressure on large blood vessels over years, sometimes decades, gradually worsening their condition.

When cerebrovascular disease occurs, treatment must be administered within a very short period of time.
In the case of cerebral infarction, thrombolytic agents must be administered within 4.5 hours of the onset of symptoms to be effective.
If it is delayed any longer, the risk of cerebral hemorrhage increases, so thrombolytics cannot be used.

The most important information in stroke treatment is 'when did the symptoms start?'
Because the optimal treatment with fewer complications will vary depending on how long it has been since symptoms started.

It would be helpful for patients or their caregivers to know the time and minute when symptoms occurred.
If you did not see the moment the symptoms appeared, you should record the time the person was normal and the time the symptoms appeared, and then report this to 119 or medical staff.

Identical twin studies support this.
According to a 2016 Nordic study, when one identical twin is diagnosed with cancer, the other twin's risk of developing cancer is only about 14% higher than in the general population.
Of these, 62% develop other cancers.


This suggests that environmental factors, in addition to genetic abnormalities, play a decisive role.
Epigenetic research suggests that differences in cancer risk between twins with identical DNA are due to differences in the regulation of gene expression caused by different environmental exposures.
For example, in twins with identical genes, one smoking habit was found to change DNA methylation patterns, which can advance the onset of lung cancer by up to 12 years.

Our body's normal body temperature varies slightly depending on the measurement method, but is usually defined as 36.5 to 37.4℃.
This temperature provides the optimal environment for our body's enzymes and cells to function most actively.
Immune cells are very sensitive to body temperature.


What happens when your body temperature rises? When your body temperature rises to 39°C (102°F), the mild fever stage, immune cells such as T cells and NK cells become more active and proliferate.
This helps your immune system fight infections.
