Stress has become a common situation in our modern society. Nowadays, with the constant development of many social aspects, one day with only 24 hours seems to be not sufficient with an active person. As a result, people always have to confront stress, which is adversely uncomfortable. To be more specific, the three main causes of stress refer to career, relationship and health-related problems.

First of all, work and study play an important part in our life, but they are also the main reasons for stress. The high development of the industrial era coinciding with the more competitiveness among companies lead to a significant increase in the employers' workload. They have to choose between being unemployed or standing high pressure. Unfortunately, both result in negative feelomg, which we often call "stress". Moreover, not many people have a good time-management skill, so they must deal with the difficulty of balancing work, study and relaxation. In brief, someone who pays too much attention on career may be the victim of stress.

Secondly, while it might be argued that having a ralationship benefits human being, the truth is that failure in relationships is also a cause of stress. There relationships could be among family members, friends or colleagues. For instance, parents do not have enough time to spend with their children, colleagues feel jealous with each other because of the career prospect, etc. As a consequence, many people have pressure at work but even outside the working environment, they cannot feel more relaxing and comfortable due to the complicate relationships.

Last but not least, people may experience stress because of bad health. While physical exercises are really beneficial for reducing tiredness, people often neglect them and continue to confront stress consequently. On the other hand, a minority suffers some kinds of perplexing disease; taking sleep deprivation as an example, they always feel sleepy even in daytime. According to the scientific research, these people cannot evade from stress which is the symptom unless they recover from these unique diseases.

In summary, there has been more and more causes of stress beside career, social relations and health. However, they are unavoidable parts of our life, so the only think we can do is to accept that existing situation and find efficient ways to reduce stress as much as possible. In stead of feeling nervous, we should enjoy our life and always think positively.
