Intermittent fasting (IF) has gained popularity as a weight loss and health improvement
strategy. By alternating between periods of eating and fasting, many people have
experienced various benefits, including improved metabolic health and weight
reduction. However, one surprising side effect some individuals report is a flushed
feeling in the heart.
This sensation can be attributed to several physiological changes that occur during
fasting. Firstly, fasting can lead to the release of catecholamines, such as adrenaline,
which increase heart rate and blood pressure, potentially causing a feeling of warmth or
flushing in the chest. This is a natural response of the body to the perceived stress of
fasting.
Moreover, IF can improve cardiovascular health by reducing inflammation and oxidative
stress, leading to better overall heart function. The initial stages of fasting might cause
a temporary increase in heart rate and blood flow as the body adapts to the new eating
pattern, contributing to the flushed sensation.
It is important to note that while a flushed heart feeling can be a benign response to IF,
persistent or severe symptoms should be discussed with a healthcare provider. Overall,
intermittent fasting can be a powerful tool for heart health, provided it is practiced
safely and under appropriate guidance.
