Norwalk Hospital will host a Red Cross community blood drive to benefit patients in need on Friday, July 15, from 8 to 1, in the Patio Room on the fifth floor. Donors must be at least 17 years old, weigh at least 110 pounds and be in general good health. The Red Cross recommends drinking plenty of fluids on the day of donation, wearing comfortable clothing with sleeves that can be rolled up, eating iron-rich foods in the weeks prior to donation and bringing a list of any medications taken along with a photo I.D. or blood donor card. The actual donation only takes about 10 to 12 minutes, but donors should allow one hour for registration, a confidential health history session and refreshments after their donation.
