How much cardio exercise you do depends on your current fitness level, exercise history, current health status, and goals. For general health benefits you should perform 30 minutes of cardio activity, 5-7 days of the week. Any activity that increases your heart rate and breathing rate can be considered cardio exercise. If you find that 30 minutes is a little too challenging, start with 5-10 minutes and gradually work up to 30 minutes.
Symptoms & Signs. Hairy tongue, medically known as lingua villosa, is generally a harmless condition that alters the appearance of the tongue, making it appear discolored and furry. Hairy tongue is also commonly referred to as black hairy tongue (lingua villosa nigra), but the tongue discoloration may appear white, brown, pink, or green. The color of the tongue depends both on the underlying condition plus the presence of any additional factors, such as the type of food consumed.
Long-Term Monitoring. If hairy tongue is noted in a patient as part of a routine outpatient examination, encourage the patient to gently brush or scrape the tongue as necessary to debride the area. In addition, encourage the patient to consult a dentist.
