Stress affects everyone differently. But two types of emotional stress can impact the heart.

Acute stress usually occurs suddenly after a traumatic event, like a car crash or an earthquake, while chronic stress builds up over time.

Karoshi (過労死, Karōshi), which can be translated literally as ‘Overwork death’ in Japanese, is occupational sudden mortality.

The major medical causes of Karoshi deaths are heart attack and stroke due to stress and a starvation diet.
