TREATMENT OF CUTS AND BRUJSES

of the body where increased oxidation is taking place as the 

 result of the exercise. The best forms of exercise are those which 

 give work to as many muscles as possible — walking, out-of-door 

 sports, any exercise that is not violent. Exercise should not be 

 attempted immediately after eating, as this causes a withdrawal of 

 blood from the digestive tract to the muscles of the body. Neither 

 should exercise be continued after becoming tired, as poisons are 

 then formed in the muscles, which cause the feeling we call fatigue. 

 Overdoing in any sport or game is dangerous. Fatigue is a signal 

 to rest. Remember that extra work given to the heart by extreme 

 exercise may injure it, causing possible trouble with the valves. 

 Older people and those who through excessive use of stimulants 

 or tobacco or other causes have developed arteriosclerosis, 1 

 hardening of the arteries, need to be especially careful. " A man 

 is as young as his arteries," because the hardening of the wall 

 raises the blood pressure, and if 

 the inelastic artery wall breaks, 

 due to overexercise, death may 

 result through apoplexy. 



Treatment of cuts and bruises. 

 Blood which oozes slowly from a 

 cut will usually stop flowing by 

 the natural means of the forma- 

 tion of a clot. A cut or bruise 

 should, however, be washed in a 

 weak solution of lysol or some 

 other antiseptic in order to pre- 

 vent bacteria from obtaining a 

 foothold on the exposed flesh. 

 If blood gushes from a wound, in 

 distinct pulsations, an artery has 

 been severed. A tight bandage 

 known as a tourniquet (toor'ni-ket) 



must be tied between the cut and the heart, If a vein is cut, the 

 blood flows smoothly. In this case, a tourniquet is applied on the 

 side of the cut away from the heart.
