Into the summer after the elderly how to health care?

In the summer time, the whole weather is just particularly hot, ultraviolet rays on our skin will also cause a particularly large impact, the elderly is also not allowed to blow air conditioning, because it will have an impact on the bone quality.

My grandfather in the summer is to fan himself with a fan, to maintain a state of natural wind, and no matter how hot the weather, he will go to drink hot water, because the elderly he will have a stomachache if he drinks cold water, at this time it will be very good to protect their stomach.
