Seriously, you need that sun block.  With temperatures expected to creep up toward 100 degrees at times, Providence Milwaukie Hospital ER Doctor Chad Byars has a reminder: lather it on every couple hours, and don't forget about the little ones. 

Dr. Byars says sports drinks will help rehydrate and suggests checking on elderly neighbors and family members as the weekend progresses. Their bodies do not adjust to the heat as quickly as younger bodies and some prescription drugs can make the heat even more unbearable.
