First, the mobile phone "weave the scarf", weave three major diseases 1. "Phone Hand"
Medically known as "throat tenosynovitis." Often using a thumb to press a button on a mobile phone will make the thumb feel stiff, painful, and even cause muscle atrophy in severe cases.
This leads to swelling of the tendon, causing repetitive strain injuries and even severe tendonitis.
It is recommended that you do not send text messages for a long time. Your fingers should take a break for a while, and you can also make appropriate massages or hot compresses.
2. "Blackberry thumb"
Frequently use the phone to write microblogging, careful to cause your thumb to turn over, even ulcers and blisters.
3. "Cell phone dermatitis"
The long-term use of mobile phones may cause an allergic reaction to the nickel casing of the mobile phone, and then give birth to a red or itchy rash, ie, "skin dermatitis."
Second, regular exercise hand, health coup 1. Circle massage Ten fingers using the thumb pulp, from the roots of the fingers to the fingertips, followed by circular massage ten fingers.
2. Rotate and massage each finger with one hand, then make a fist and then massage each finger of the other hand until it warms up.
3. The Yangchi point on the back of the hand massaged the fingers of the body warmly upwards. There will be several wrinkles on the wrist. Press on the wrinkles on the side of the back of the hand and a tender point will be found in the center. This point is the Yangchi hole. As long as you stimulate this point, you can quickly clear the blood circulation and warm the body.
4. Scratch the palm of your hand on the kidney reflex zone. Scratch the area with the hand 2 in a single direction, and scrape it until the skin is flushed and hot.
Note that when the finger joints slide "scraping", the direction should be from the palm to the wrist.
