Preventing Heat Stroke

Prevent Heat Stroke 1 Limit the time you spend outdoors to the early morning and evening hours. The temperature is cooler and this is a good time to exercise or accomplish other outdoor tasks such as gardening. 2 Bump up your fluid intake. Prevent heat stroke by drinking even when you are not thirsty. You want to prepare your body for the heat, not wait until it gets the best of you. If exercising drink two to four glasses of cool water an hour. Replenish your body of the salt and minerals you lose while perspiring by drinking a sports beverage. 3 Steer clear from overly sugary drinks. These beverages can cause you to lose more body fluid. Also, pay attention to the temperature of drinks since very cool drinks can cause heat cramps in your stomach. 4 Stay inside as much as possible on hot days. Make use of the air conditioner. If you do not have an air-conditioned home, visit the mall or another public place for a few hours. This can help your body stay cool even when you go back to the warmer environment. 5 Dress appropriately. Wear loose-fitting, well-ventilated, thin clothing in light colors. A black shirt, or other dark color, can absorb the sun and raise your body temperature. click here for more

Coffee's Anti-Cancer

Coffee has been shown to reduce the risk of skin cancer by helping kill off damaged cells that could otherwise turn into tumors, according to a US study published on Monday.

The findings indicate that moderate caffeine drinking, or perhaps even applying coffee to the skin, could be useful in warding off non-melanoma cancer, the most commonly diagnosed of all skin cancers.

Using mice that had been genetically altered to suppress a protein enzyme called ATR, researchers showed that the mice were able to fend off cancer even when exposed to ultraviolet light.

Previous studies have suggested that drinking about a cup of caffeinated coffee per day has the effect of suppressing ATR and triggering the die-off of cells harmed by UV rays.

The altered mice eventually did develop cancer, but three weeks later than normal mice, according to the study published in the Proceedings of the National Academy of Sciences.

After 19 weeks of ultraviolet light exposure, the engineered mice showed 69 percent fewer tumors and four times fewer invasive tumors than the control group.

However, the protective effects only went so far. After 34 weeks of UV exposure, all the mice developed tumors.
