Dangerous signs of diseases in summer easy to overlook - Wrinkles -

​Wrinkles
 
One of the causes of wrinkles is UV. The stratum corneum gets thicker to block UV. The thickened stratum corneum gets dry and becomes wrinkles.
 
But if you avoid UV too much,  there is a possibility that the bone could be weakened. Our body makes the bone from vitamin D and calcium. Vitamin D is made by soaking in the sun. That is why if you avoid the sun light, you can’t make the bone in your body.
 
You can prevent wrinkles and spots and also protect the bone by absorbing UV from the palms of your hands because the palms don’t have melanin pigments that block the UV so that vitamin D can be made efficiently in a short time. Sufficient UV can be absorbed by soaking your palms in the sun for 15 minutes a day.
 
Wrinkles that could be a sign of dangerous diseases
 
Wrinkles made in the ear lobe could be a sign of heart diseases (Fig. 1).
 
The ear lobe doesn’t have many blood vessels so that the ear lobe is easily affected by hardening of the artery (arteriosclerosis) and wrinkles are made by poor blood circulation due to hardening of the artery. The ear lobe is one of rare spots in our body where we can check the condition of our blood vessel.
 
It is said that wrinkles on the forehead are also made by hardening of the artery, but they are made by UV as well, so  the ear lobe that is not easily affected by UV is more useful to check the condition of the blood vessel.
 
According to a survey conducted on 108 people whose ages were 54-74 year old for 8 years in Chicago University, people who had wrinkles in the ear lobe tripled the risk of heart diseases.
 
Eating blue back fishes is recommended to prevent hardening of the artery because EPA contained in blue back fishes improves the blood flow and helps prevent hardening of the artery.
