Redness of the hands/palms can be due to capillary dilation. This is a common response that the body has to try to cool off. We transfer more heat to the air by increasing blood flow to capillary beds near the skin..
There can be many factors associated with how open or closed the capillary beds are however>>heat is just one of these factors...
The blotchy appearance can be associated with a decrease in flow. It is referred to as mottling. It may be casued by low blood pressure as one possible cause.
Sometimes people will have mottling when they are fighting an infection..
Hormaonal factors can play a role in the vascular changes that may be seen as red palms or mottling.
Sometimes vascular changes can be associated with autoimmune disease >>especially those with a componant of vasculitis (inflammation of blood vessels)
Certain medications may cause vasoconstriction and this may cause a mottling apearance.Smoking can cause vasoconstriction and so this can be a factor in the mottled appearance of the skin.
Sure that could be the case. When you move around your body will generate more heat.
Your body will make a variety of adjustments to disperse excess heat...
OK well I hope this helps. As long as it does not bother you I would not worry too much about it. I would keep an eye on the itching symptom if this should be an ongoing or increased symptom.
When cold I would expect that you would be more likely to have the mottled appearance than bright red and warm.
Some people are susceptible to vasoconstriction of the blood vessels to the hands to the point that the fingers ache. This is referred to as Raynaud's phenomenon when severe.
When you come inside from the cold and warm up then you may have the warm red palms again...
If it is not bothering you then I would not be so inclined to worry about it. If you have other symptoms of concern then further evaluation may be warranted. If you have other symptoms for example (feel abnormally warm compared to your peers, rapid heart rate, weight loss >>these could be associated with an over-active thyroid for example)
If you have much of that itching or develop a frank rash then allergies, or auto-immune disease may be screened for...
