Why does the skin turn white when warm and dark when cool, and how to treat it?

The skin turns pale when warm and dark when cool, which may be due to physiological factors or pathological conditions such as coronary atherosclerotic heart disease or hypertrophic cardiomyopathy. Treatment can be achieved through general management and medication. Specific details are as follows:

I. Physiological Factors

When the surrounding temperature is relatively high, blood circulation accelerates, causing the skin to appear pale. When the ambient temperature is low, blood circulation slows down, leading to hypoxia and resulting in darkening of the skin. It is important to keep warm and avoid exposure to cold.

II. Pathological Factors

1. Coronary Atherosclerotic Heart Disease

With increasing age, degeneration of the coronary arteries, insufficient myocardial blood supply, and coronary artery stenosis may occur, leading to myocardial dysfunction or organic lesions, resulting in the aforementioned symptoms. Under medical guidance, patients may take medications such as atorvastatin calcium tablets or enteric-coated aspirin tablets for treatment.

2. Hypertrophic Cardiomyopathy

In patients with hypertrophic cardiomyopathy, asymmetric thickening of the ventricular wall and narrowing of the ventricular cavity can obstruct left ventricular filling, causing the above phenomena. Under medical supervision, drugs such as spironolactone tablets or metoprolol succinate extended-release tablets may be used for treatment.

Besides the causes mentioned above, this condition could also be caused by pulmonary heart disease. During treatment, it's important to maintain an optimistic mindset and avoid emotional excitement. Appropriate physical exercise is recommended to enhance immunity.
