What causes redness in the palms?

Under normal circumstances, redness of the palms may be caused by emotional excitement, changes in environmental temperature, unhealthy lifestyle habits, systemic lupus erythematosus, cirrhosis, and other reasons. If discomfort occurs, it is recommended to seek medical attention promptly. The specific analysis is as follows:

1. Emotional Excitement

When emotionally excited, levels of adrenaline and noradrenaline in the body rise, causing blood vessels to dilate and blood circulation to accelerate, leading to congestion and redness of the palms. It is advisable to regulate emotions appropriately to reduce palm redness.

2. Environmental Temperature Changes

In cold environments, the body constricts peripheral blood vessels to maintain core temperature. When these vessels subsequently re-expand, blood rapidly flows into the palms, causing them to turn red. Adjusting clothing and maintaining a suitable ambient temperature can help avoid direct stimulation from extreme temperatures.

3. Unhealthy Lifestyle Habits

Poor lifestyle habits such as excessive fatigue, alcohol consumption, and staying up late may lead to inadequate blood supply and reduced platelet count, resulting in light red discoloration of the palms. It is important to avoid overexertion and chronic sleep deprivation, reduce alcohol intake, and maintain a healthy diet.

4. Systemic Lupus Erythematosus (SLE)

SLE is usually triggered by genetic factors, ultraviolet radiation, or abnormal hormone levels. This condition causes the immune system to mistakenly attack the body's own tissues, triggering inflammatory responses that affect skin blood vessels and result in redness of the palms. This is often accompanied by symptoms such as rashes and fatigue. Treatment may include medications such as prednisone tablets, ibuprofen tablets, and cyclophosphamide tablets, taken as directed by a physician.

5. Cirrhosis

Cirrhosis may result from long-term excessive alcohol consumption, obesity, diabetes, and other factors. When liver function is impaired, the liver cannot effectively clear estrogen from the body, leading to elevated estrogen levels, which in turn cause palmar congestion and redness. This condition is often accompanied by symptoms such as jaundice and ascites. Medications such as spironolactone tablets, entecavir tablets, and ursodeoxycholic acid tablets may be used under medical supervision for treatment.

In daily life, dressing appropriately and taking proper warming measures according to environmental temperature changes are recommended, avoiding prolonged exposure to extreme conditions. Additionally, maintaining regular作息 (daily routines) and sufficient sleep, avoiding staying up late and excessive fatigue, is essential for overall health.
