               Caring for smell and taste

               Caring for the senses of taste and smell allow for smells and flavours to be
               perceived properly. Some healthy habits to take care of them are:
                  • Use a handkerchief, preferably disposable, to blow your nose.

                  • Breathe through the nose to heat the air that enters your lungs; this helps
                to avoid colds.

                  • Brush your teeth and tongue with a toothbrush and toothpaste.
                  • Do not eat very hot or very cold foods.

               Ear and eye care

               For proper hearing and to prevent infection, the external ear canals must be
               kept clear. To clean the ear, only soap and water or physiological solutions
               should be used. Cotton swabs should never be put into the ear.

               The  eyes have their  own cleaning mechanism  made up  of the  lacrimal
               system and the eyelids, which keep the external surface of the eyeball
               clean and moist. To take care of the sense of sight, it is good to adopt
               healthy habits:

                  • See an ophthalmologist if you notice that it is difficult for you to focus or
                your eyes are fatigued.

                  • Use a good light to read and study.
                  • Always keep a sufficient distance from television or computer screens
                and do not spend too much time in front of them.
