caffeine-cancer.jpg Skin cancers are the most common cancers in the United States. A recently concluded study has proved that a combination of caffeine and regular exercise may keep skin cancer at bay. Dr. Allan H. Conney, senior author of the study, however cautions that this does not mean that people should give up sunblock. The results of this study have been published in Proceedings of the National Academy of Sciences.

Study Highlights
a. Researchers studied 4 groups of hairless mice.
b. One group was made to drink caffeinated water daily, another group was exercised on a running wheel, the third group got both caffeine and exercise and the fourth group had neither.
c. All the mice were exposed to UVB radiation that damaged the skin cells' DNA.

Conclusion of the study
a. It was seen that all the mice had some degree of healthy, programmed skin cell death.
b. The group that was given only caffeine and the exercisers emerged as the healthiest lot and were able to kill the damaged cells.
c. Researchers also studied the physical changes in those cells and the chemical markers like enzymes that helped in killing the damaged cells.
d. It was noticed that there was a 96 per cent increase in damaged cell in the caffeine drinkers.
e. The exercisers had a 120 per cent increase in damaged cells.
f. The mice that got both caffeine and exercise exhibited almost 400 per cent increase in cell death of damaged cells.
