How about alcohol tolerance of redheads? Or temperature sensitiveness? How many special treats are associated with inglorious MC1R protein?
Several studies proved people with red hair (natural or dyed) act significantly different than everybody else, but their behavior could be influenced by the heavy mixture of historical and cultural heritage.
On the other hand, pain and amount of medication needed to suppress it are undeniably measurable. What a so-called hard science says about natural redheads and pain?
Can you add anything related to redheads and pain?
Skin freckles are not directly connected with pigmentation. Lower amount of pigment can lead to higher contrast but freckles are actually a result of hyper pigmentation - even if we are dealing with a low pigmentation in overall.
The fourth paragraph under your subheading Heat and Reds indicates that redheads "produce less pigment as a skin protector against UV rays), but not for cold."
Would that lower pigmentation account for some skin freckling and other skin not and would that mean that redheads feel greater pain from sunburns?
When the color of hair changes, your genetics stays the same, what means this should not affect your pain tolerance. On the other hand we all know pain threshold can be changed with proper training. Ladies who clean the fish in ice cold water can bare unbelievable amount of coldness, no matter what kind of hair they have.
Thanks for your comment, frankbeswick.
One issue is that hair colour can change. When young my head hair was golden, and people classed me as ginger, but it changed over the years to brown, now grey. But my hair on arms and legs has remained golden. So how does this affect the issue of red heads and pain? This being said, this was a good article.
