Another reason to wash hands: Flame retardants – Study

As if protecting ourselves from the deadly coronavirus weren’t reason enough, here is yet another important reason to wash our hands thoroughly and often.

Harmful flame retardants may be lurking on your hands and cell phone, according to a peer-reviewed study published today in Environmental Science & Technology Letters.

The researchers found that halogenated flame retardants added to plastic TV cases can move from the TV to indoor air and dust, to hands, and then to cell phones and other hand-held electronic devices. Once on your cell phone, that surface provides an ongoing source of exposure to these chemicals each time you touch your cell phone.

“It’s well-known that viruses are transferred between surfaces and hands,” said co-author Miriam Diamond, a Professor in the Department of Earth Sciences at the University of Toronto. “Our study shows that toxic chemicals like flame retardants do the same. That’s another reason we should all wash our hands often and well.”

5 Exercises to improve hand mobility – Harvard

I have written numerous times about the arthritis I suffer from in my hands and the various techniques I have tried to relieve the pain. Here is Harvard with five exercises that will restore some of the mobility in your hands.

If you find daily tasks difficult to do because you suffer from stiffness, swelling, or pain in your hands, the right hand mobility exercises can help get you back in motion.



Therapists usually suggest specific exercises depending on your particular hand or wrist condition. Some help increase a joint’s range of motion or lengthen the muscle and tendons via stretching. Other exercises strengthen muscles around a joint to generate more power or to build greater endurance.

Your muscles and tendons move the joints through arcs of motion, such as when you bend and straighten your fingers. If your normal range of motion is impaired — if you can’t bend your thumb without pain, for example — you may have trouble doing ordinary things like opening a jar.

These exercises move your wrist and fingers through their normal ranges of motion and require all the hand’s tendons to perform their specific functions. They should be done slowly and deliberately, to avoid injury. If you feel numbness or pain during or after exercising, stop and contact your doctor. Continue reading

How to Deal With Arthritis of the Hand – Harvard

They pour our coffee, brush our teeth and perform hundreds of other daily tasks too numerous to mention. “But aching hands transform even a simple task into a painful ordeal. Beneath the skin, your hands are an intricate architecture of tendons, joints, ligaments, nerves, and bones. Each of these structures is vulnerable to damage from illness or injury. Arthritis can make it difficult to carry a shopping bag,” according to Dr. Barry P Simmons, Medical Editor of Harvard Health Publications.

Harvard has issued a 44 page report entitled Hands. This Special Health Report from Harvard Medical School, includes super-informed coverage of The Healthy Hand, Arthritis of the hand, Tendon trouble, Exercise for the hand, Carpal tunnel syndrome and other tunnel syndromes, traumatic hand and wrist injuries as well as handy gadgets. This pretty much qualifies as everything you ever wanted to know about the hand, but were afraid to ask. Harvard Medical School offers special reports on over 50 health topics. Visit their website for further reports of interest to you and your family. You can order the Hands report here.

The following is directly from the report:

The most common of all joint diseases, osteoarthritis affects cartilage, the resilient tissue that cushions the ends of your bones. Normally, cartilage provides a smooth, gliding surface so the joints can move easily. In osteoarthritis, the cartilage thins and loses its elasticity. As the cartilage breaks down, the underlying bone may form a bony growth called a spur, or osteophyte. Fluid-filled cysts may form in the bone near the joint. The synovial membrane lining the joints becomes inflamed, triggering the release of proteins that may damage the cartilage further.

Approximately 27 million Americans have osteoarthritis. In addition to the hands, osteoarthritis typically strikes the knees, hips, feet, and back. The incidence rises with age, with most cases occurring in people older than 50. Heredity seems to play a role, particularly for osteoarthritis in the hands. Muscle weakness and a history of joint injuries caused by sports or accidents may also make a person more prone to a type of osteoarthritis known as traumatic arthritis. Ordinary, repetitive activities such as typing or playing a musical instrument may worsen arthritis symptoms, but they do not cause osteoarthritis of the hands.
