PUT YOUR FINGERTIPS INTO COLD WATER AND IN 30 SECONDS YOU WILL KNOW IF YOU ARE HEALTHY
A simple trick can reveal a very important thing about your health
Pour very cold water into the cup and put your fingertips into it for 30 seconds. After this time you will get a clear sign that you are healthy or have a health problem.
If your fingertips become white or blue, you have a circulation problem.
A significant change in temperature (or stress) may cause blood vessels to flare up to the fingers, nose or ears.
As a result, these parts of the body do not get enough blood and can harden.
Circulation problems can be caused by blood clots that can be very dangerous, because if they are broken, they can reach the heart or lungs and become potentially deadly.
