Carpal tunnel syndrome
Lift your hands up, and make sure your forearms are parallel with your face. Try reaching the base of your palm with your fingertips. If you feel tingling after doing this for more than 2 minutes, it is a sure sign of carpal tunnel syndrome, which appears when “ neighboring tissues press on the median nerve, and the pain and numbness will surely get worse in time, if you don’t treat this properly”. This syndrome is common among office workers and bikers, because of the sitting position and their hand always reaching out.
Hearing problems
sit in a quiet room and put your hands close to your ear, rubbing your fingers from each other. Repeat this from different distances on both ears. If you can hear the sound every time, your hearing is just fine.
Problems with your arteries
Lie on the floor and put your feet up facing the wall, at about 45 degrees angle, holding them like this for 10 minutes. If the feet and toes become really pale, you have a bad blood circulation. This condition is called “peripheral artery disease”, or, PAD, and if you don’t treat it, it might cause bigger problems, such as heart disfunctions and a stroke.
