Thanks to the senses, a person is capable ofto perceive various information from the environment and analyze it. This ensures its full-fledged existence. How should the sense organs be protected so that they effectively perform their functions throughout the life of a person? Let's understand together.
A person perceives this world throughPhysiological structures, which are called sensory systems. There are five in total. It is visual, auditory, olfactory, tactile and tasteful. Each of them is unique and has its own structural features. However, the common for all sensory systems is the presence of three departments. The peripheral is represented by receptors, the conductor is the nerve fibers, and the central one is the bark of the large brain.
Departments of sensory systems work in concert. A violation of the functioning of any of them entails a failure of the entire structure. Often, this is due to the unreasonable behavior of a person. Thus, scientists have proved that about 95% of people are born with good eyesight, and lose it as a result of unreasonable exploitation. Therefore, it is very important to observe simple rules of hygiene of the senses.
How to protect the sense organ that providesAre we 90% of the information? It's not that hard. First, do not let the lens get tired, because as a result, it can lose its elasticity. To prevent this, you do not need to read in transport, because the lens has to constantly change its curvature for focusing. It is also not recommended to read in poor lighting. Correctly, if the light falls to the left, it does not form a shadow, and the distance to the book is at least 30 cm. The computer monitor should be placed even further - up to 50 cm, and the TV and even more - about 2 m. Let the eyes rest every 15-20 minutes . Of course, with bright lighting and harmful microorganisms, the visual system has its own mechanisms of struggle. But sunglasses in clear weather, special masks for working in hazardous industries, proper organization of the workplace, personal hygiene are also necessary. Another pledge of excellent vision is the presence in the food of vitamin A, which is very rich in cod liver, blueberries, parsley and green onions.
In the power of man and keep the ears. After all, the most common cause of its violation is very trivial - the accumulation of sulfur in the auditory canal. It is necessary to get rid of this substance very carefully, so as not to damage the eardrum. Inflammatory processes of the middle ear can be a consequence of penetration into the middle ear of pathogens through the nasopharynx and complications after the flu or sore throat.
How to protect the organ of the feeling in question, inEveryday life? Do not often listen to loud music, especially with the help of the player. This reduces the elasticity of the tympanic membrane. Just imagine: the intensity of the sound of ordinary conversation is about 60 dB, and the disco - 110. For comparison: the same figure for a jet plane is very little less - 130 dB. A particularly big problem is systematic household and transport noise in large metropolitan areas.
Specific sense of smell formsolfactory system. Its receptors are located in the nasal cavity. They can weaken their work during colds accompanied by a runny nose. Thus the person loses ability to distinguish any kinds of smells. Food becomes tasteless. Agree, during the cold most favorite dishes no longer cause adequate appetite. How to cherish the sensory organ that forms the taste? It is very important to monitor the hygiene of the oral cavity, teeth and tongue, on which the receptors are located. Never try to eat and drink both very high and low temperatures.
The largest organ of a person is the skin,which serves as an organ of touch. It contains a wide variety of receptors. With its help, we perceive pressure, tension, temperature change, pain, character and shape of surrounding objects. Everyone should observe the rules of skin hygiene, systematically take a shower, monitor the purity of clothing. Be careful of burns and frostbite, never touch dangerous objects, unfamiliar plants and animals.
Absolutely on all sense organs negatively affect bad habits. Smoking, alcohol and drugs reduce the threshold of receptor sensitivity and cause dangerous diseases.
How to protect the senses? Touch, smell, sight, taste and hearing constantly demand hygiene rules. If you know and do them, lead a healthy lifestyle and think about your safety, all sense organs will function effectively and give the variety of sensations of this world.
