How to protect the senses? Memo to schoolchildren and adults

The system of the human senses is part of the nervous system. It is the senses or, as they are called, sensors that can perceive the information that surrounds us. They, with the help of nerve impulses, transmit information to the brain, where its analysis takes place. Why all this is necessary?

The sense organs are extremely necessary for living beings, we simply could not survive without them. How do I get my food if there are no eyes? How to distinguish the smell of vinegar from the smell of water, if there are no organs of smell? And how do we understand that we are unwell (hit, cut or burned) if there is no tactile perception? A person without sensory systems can not exist uniquely. That's why we will discuss a rather important problem - how to protect the senses.

Memos of this kind should be present in schools, universities and even in kindergartens. It is very important for the child to inform from the very early age that the sensory systems of his body must be protected.

The first thing you need to know is that the human senses have only five: vision, smell, hearing, taste, touch. Speaking very simply, we are able to see, smell and taste, hear and feel tactile. Each sense organ has its own specific features, so we'll look at each individually.

Sight and his protection

When does a person first learn such a term as the sense organs? The 4th grade of primary school gives such information, but parents should take care of this problem much earlier than children will have a short biology lesson on this topic.

From the very first days of life, it is the eyes that make it possible for a child to study until the unknown world around him. With the help of vision, we not only see objects, colors and forms, but also determine the spatial position of the object. Thanks to this sense organ, a person is able to write, read, get acquainted with the masterpieces of literature and art, and this is important for the development and formation of personality.

We are surrounded by a large number of different stimuli, but visuals are of particular importance, because 90 percent of the information we get is due to sight. It is for this reason that we will understand how to protect the senses, and, more specifically, vision. It is necessary to follow certain rules:

• Good lighting during reading.
• Prohibition of smoking.
• Nutrition useful for vision.
• If you wear glasses or lenses, be sure to take care of them.
• Change lenses and glasses in time.
• If the doctor prescribed glasses, they should be worn.
• Visit a doctor.
• Correctly handle the computer, TV, telephone and so on.
• Do a simple gymnastics during the day.

These simple actions will help you keep your eyesight or even improve if you do not run this problem. Remember that vision can deteriorate due to a mechanical injury, so protect them with special glasses or a mask during dangerous work. Do not look at bright light sources (laser or welding).

Taste

Everyone knows that the organ of taste is the language. It is a mobile muscle, one of the most powerful in the human body. The surface of our tongue is not smooth, but rough, this can be explained by the presence of a large number of small papillae, which help us determine the taste of food. All papillae can be divided into the following groups:

• Threadlike.
• Conical.
• Mushroom-shaped.
• Troughs.
• Sheet-shaped.

Based on the form, they perform some specific functions. Now a small list of rules, how to protect the senses (taste buds):

• You can not eat much hot food or drink boiling water.
• Be sure to wash your hands before eating.
• You can not take in your mouth unknown drugs, plants and other items.
• Remember the golden rule: "when I eat - I am deaf and dumb." Do not talk while eating, this will help you not choke.

Smell

The organ of the senses here is the nose. Thanks to him, we not only can feel the wonderful fragrances, but he warns us of many dangers, such as fire or gas leakage. It is very important to know how to protect the sensory organs, including the olfactory receptors.

• Do not breathe an unknown liquid directly from the container, direct air to the nose with the help of hand movements.
• For the sense of smell is very harmful dust, do daily wet cleaning and airing.
• Smoking or inhaling tobacco smoke can also worsen your sense of smell.

Hearing

The organs of hearing are our ears, with which we perceive various sounds. The latter are oscillations propagated by means of a sound wave. Not all sounds are audible to a person, there are certain limits, and the sounds coming out of their boundaries are infrasound or ultrasound. Hearing is necessary, and how to do it, we'll look at it right now. Memo, how to protect the senses (hearing):

• You can not shout in your ear and listen to loud music.
• Do not clean your ears with sharp objects, otherwise you can damage your eardrum.
• Daily wash or clean your ears.

Touch

We have left the last sense organ - the skin, it is she who participates in the process of touch. It has the main function - protecting the body from external influences. The skin helps us to distinguish between heat, cold, pain and so on. We pass to the main question. So, a reminder how to protect the senses:

• Take a bath or shower every day.
• Wear clean and quality clothing.
• Avoid burns, cuts, frostbite and so on.
• You can not touch unfamiliar plants and street animals.

By observing these simple rules, you can keep your senses healthy for a long time.
