Noise-Induced Hearing Loss

Every day, we experience sound in our environment, such as the sounds from television and radio, household appliances, and traffic. Normally, we hear these sounds at safe levels that do not affect our hearing. However, when we are exposed to harmful noise—sounds that are too loud or loud sounds that last a long time—sensitive structures in our inner ear can be damaged, causing noise-induced hearing loss. Today's lesson focuses on how to take care of our auditory system, so that we can hear perfectly later in life.

New strain of MRSA

It’s referred to as the ‘super bug’; MRSA kills 21,000 people in the US each year and it is thought to be picked up in public places and then spread around hospitals by people acquiring outpatient procedures.  Fortunately this new strain is easier to treat, but still deadly to those with weak immune systems; Melissa Long reports for Today’s Health Minute.
