Whether people realize it or not, science and technology have deeply influenced our daily life and played an indispensable role in economic and social development. Since the 20th century, with the rapid development of science and technology, especially computer network technology and electronic information technology, expensive luxuries such as mobile phones and computers have entered the homes of ordinary people and become necessities of our lives. Imagine how we can keep in touch with our relatives at will without mobile phones. If there is no internet, how can we talk with friends in foreign countries? Without HDTV technology, how can you enjoy gorgeous Hollywood movies? Of course, we must also admit that science and technology have changed our way of life and culture to some extent. It is precisely because of the importance of science and technology that our national leaders have repeatedly proposed to vigorously develop science and technology.

Hygiene and health are closely linked, and hygiene is the premise of our health. It is often said that once you get sick, it will inevitably affect your health. Therefore, it is very necessary to pay attention to food hygiene.

Especially recently, I heard a news that a woman in Changchun died because she had been holding mala Tang and rice noodles for a long time. After listening, I was really shocked. Because I usually like to eat mala Tang and rice noodles. Besides mala Tang and rice noodles, we'd better not buy some foods that are often sold on the roadside and in the streets and lanes, such as oil cakes and stinky tofu, as well as the stalls of those vendors. Who knows what these things are made of? They are unsanitary. Eating it is easy to get sick.

Some people will say; Eating too much will make you healthy. This is inappropriate, we can't believe it all. Health lies not in how much you eat, but in a reasonable diet. You should always sit and exercise, drink plenty of water, eat on time every day, go to bed early and get up early, so as to be healthy.

In order to have a healthy body, we should develop good hygiene habits in peacetime. First of all, we should start from ourselves. Good hygiene habits are manifested in the little things in life. For example, keep yourself clean and tidy, change clothes frequently, take a bath frequently, and cut your nails frequently; Wash your hands before and after meals; Also, always clean the dormitory and keep the air circulation in the dormitory; After all, the dormitory is our home at school. What we need is a clean and tidy living environment. In addition, it is necessary to participate in physical exercise properly to enhance immunity. Secondly, we should look at the overall situation. We should ensure the sanitation of our social environment and do a good job in greening and environmental protection. From the perspective of everyone's health, this is also a problem that cannot be ignored, so protecting environmental sanitation is actually protecting our personal health.
