The majority of the office staff need to take bus every day. Still，there are a lot of retired elderly people have to take bus when they go out. Almost everyone has the experience of taking bus. But few people may note that many habits on the bus may do harm to health，even affect longevity. Here we will list eight of them. I hope that those friends who regularly take bus may consult them. And if you have such habits，get rid of them timely：

1.Should not read on the bus.

It seems that we are not at the expense of ride and study. In fact，we pay a high price in exchange for minimal returns. When the car is running，the intensity and the number of light in the bus changes at any time，which is bound to force a person's pupil constantly adjusts to adapt to the environment，directly resulting in visual fatigue and accelerating eye cells aging，therefore，the vision continues to drop. If you’re highly concentrated when you are reading，it is bound to  maintain a fixed position for a long time，and the consequences will be back pains and numbness of extremities. If therefore resulting in reaching your stop without noticing，isn't it a trouble？

2.Should not listen to music on the bus.

With the popularity of MP3 and MP4, especially the young and the middle-aged are accustomed to carry it. What’s more，the capacity of these players is also growing, many people listen to music all day. Medical research has confirmed that the headphones of the Walkman have become the killer of the health of human being's hearing. Sound waves，through headphones(especially the earplug-style) which has a “perfect combination”with ears， watertightly send vibration to the inner ear，directly impacting on the hearing organ in the inner ear，which makes a particularly great damage to our hearing. Over time, there will be ringing in the ears, ear pain and may even trigger a otitis media，which addles one’s head even more often. Once damage is there，the result will be irreparable. If causing longtime deafness due to a spur of excitement for ears，there will be more harm than good.

3.Should not doze on the bus.

For some office workers who used to stay up late，if it takes a longer time on the bus，they can nap for a while and assume that it can help alleviate the fatigue and restore energy，in fact, this is a wrong impression. Dozing on the bus will only add to fatigue, what’s worse，it may cause skin paralysis，neurasthenia，etc.，leading to reduce the human body immunity and become particularly vulnerable to influenza. At the same time，when one enters the state of light sleep，body parts such as organs are in a semi-dormant stage, leading to slow blood flow，the nervous system begin to relax and one’s conciousness of self-protection be prohibited，once the bus arrives at the stop，brakes suddenly or even encounters an accident，a rapid restoration of the former sleepy state is bound to increase the workload of the nervous system, then the damage is inevitable. Even so，one’s stress reaction will be slow. If the accident is really there，the consequences would be unthinkable. In addition，if the human body keeps in a sitting position for a long time，it will oppress blood vessels in the leg and hip muscles，leading to the legs and feet numbness，stiff upper limbs and back stiffness, what’s worse，it will cause cervical spondylosis，varicose vein，etc. it will only damage the health.

4.Should not have a drink on the bus.

It is common that someone carries pure water，soft drinks，fruit juice and other beverages on the bus，they feel satisfied by opening the drink and taking a swallow. In fact，having a drink on the bus hiddens great risks. First, the security can not be guaranteed. It is easy to lose sight of the surrounding environment while having a drink. You may be collided by the crowd，or slipped and fell down. Once the bus speeds up or slam the brake, if you are having a drink at such a moment，it is easy to cause trachea choke by the liquid. If it is just a slight choke，it will cause coughing. If is a severe choke，it will lead to lose life. If spilling the drinks on one’s own clothes of others’，someone may also cause unnecessary troubles.

People like to eat such snacks as biscuits, chocolate, dessert, candy, and something like that on the bus，and this is a bad habit. The reason is simply. There is a great staff mobility and comprehensive personnel，not even rule out the possibility of bacteria carriers and communicators. At the same time，the health situation on the bus can not make you feel optimistic. The dust，droplets, paper, etc. inside and outside the bus will increase the pollution in the bus. If the pollution mixed with the smoking odor from those smokers and drinkers，while eating in such a kind of environment，how to avoid the food items completely free from pollution? How to ensure clean hands before eating? If someone eats contaminated food, it can easily lead to abdominal pain, diarrhea, causing enteric disease.

6.Should not put on makeup on the bus.

Everyone loves beauty，but the occasion shoud be in your consideration. Quite often，we can come across such a scene on the bus that some women take out simple dressing-boxes from pockets or handbags at will，then put powder on the face，use browpencils to draw the eyebrows，or apply lipsticks on lips. In fact，it will not only increase the possibility of the skin being infected，but worsen the pollution in the bus. In addition，it will not only expose one’s unattractiveness，but cause others to feel disgusted. Just imagine, in a very limited space and a very limited vision, can you ensure that your face is properly paited，your eyebrows are properly drawed and your lips are properly applied？Once making mistakes，the result of putting on makeup will be the opposite. The bus is stop-and-go and the accident cannot be ruled out. If someone touches head or tips due to highly concentrated on putting on makeup，the loss will be huge.

7.Should not carry pet with you on the bus.

Some pet lovers often go out with a pet，they will certainly carry the pets on the bus. The majority of the pets are cats and dogs. Carrying the pets on the bus will subject to various constraints, regardless of the owners having any seats，they should hold it，which virtually has increased the spread of pathogens from the pets and posed risks to others. Once the pet is not in good mood and shout，it will affect other passengers and destroy ownesr's mood. If the driver slams the brakes, some passengers may bump the pet and the pet may hurt others，which will harm not only others，but also the owner. This is also irresponsible to others.

This was particularly prevalent among the elderly. They carry the drugs at hand. Once seated，they will pick out one pill and put it in the mouth. Excluded the possible choking due to taking the medicine on the bus while the bus is running on the road，many people especially the elderly like to take the medicine without water because few of them carry water at hand. This will not only affect drug effect，but also caused damage to the esophagus. Thus，we shoud avoid taking the medicine on the bus.

In fact，there are still many habits that many people need to pay attention to，such as loud noise joking，frequently making calls and sending and receiving messages，distracted due to focusing on someone，and so on. Due to the space is limited，I will not repeat them.
