WARNING
Vibration and cold
It is believed that a condition called Raynaud's Phenome-
non which affects the fingers of certain individuals may be
brought about by exposure to vibration and cold. Expo-
sure to vibration and cold may cause tingling and burning,
followed by loss of colour and numbness in the fingers.

ment is unknown.

feet and ankles, and hands and wrists.

the fingers, followed by whitening and loss of feeling,
consult your physician before exposing yourself further
to cold and vibration.

Repetitive stress injuries
It is believed that over-using the muscles and tendons of
the fingers, hands, arms and shoulders may cause sore-
ness, swelling, numbness, weakness and extreme pain to
the areas just mentioned. Certain repetitive hand activities
may put you at a high risk for developing a repetitive
stress injury (RSI).
To reduce the risk of RSI, do the following:
 Avoid using your wrist in a bent, extended or twisted
position.
 Take periodic breaks to minimize repetition and rest
your hands. Reduce the speed and force in which you
do the repetitive movement.
 Do exercises to strengthen hand and arm muscles.
 See a doctor if you feel tingling, numbness or pain in
your fingers, hands, wrists or arms. The sooner RSI is
diagnosed, the more likely permanent nerve and muscle
damage can be prevented.
