This morning I stumbled upon interesting research conducted in 2001 – that is obviously quite old, but I think you’ll find it interesting (research documentation). The researchers studied a group of elderly people by comparing the degree of wrinkling of their skin and the state of their general health, lifestyle and overall well-being.
The researchers studied the skin only in areas that had not been exposed to the sun – so there is no chance that sun damage messes with results. What they found is that people with poor lifestyles showed higher degrees of wrinkling than those who lead healthier lifestyles.
It’s also interesting that people who showed less wrinkling had better immunity, stronger health, increased well-being and higher levels of DHEA, also known as youth hormone.
DHEA is associated with slower aging and increased energy and was advertised quite aggressively a few years ago. DHEA supplements are still available, but there was no studies on their long-term effects. I am not sure whether or not we should take these supplements, but eating well, avoiding stress and exercising seem like a safe way to go.
