Overthinking is a form of psychological stress that people experience due to various factors. However, it can affect overall health, including heart health. The main question arises ‘Can overthinking cause a heart attack?’. Tap to know!

High Blood Pressure

Overthinking keeps our body in fight or flight mode, leading to persistent high blood pressure, a major factor of heart attack.

Weakened Immune System

Constant overthinking can also weaken the immune system, making it difficult to fight off infections and increasing the risk of heart attack.

Sleep Disruption

Many people are unable to sleep due to constant overthinking, which may cause insomnia in some. Disrupted sleep has also been linked to heart diseases.

Reduced Physical Activity

Overthinkers may become so consumed by their worries that they engage in little to no physical activity, increasing the risk of heart diseases.
