While smoking declines after decades of awareness campaigns, lack of physical activity increases among Brazilians and raises an important public health alert
Cancer remains among the leading causes of death worldwide and, in many cases, is directly related to factors that can be modified through lifestyle changes. Although much of the population associates disease prevention with combating smoking and alcohol, experts warn that there is another risk factor affecting a much larger number of people that often goes unnoticed: physical inactivity.
The information was released based on a survey conducted by the World Health Organization (WHO), which analyzed the main factors associated with the development of cancer in different countries. The study identified habits and conditions that can be avoided and that have a direct influence on the onset of the disease.
Furthermore, the results show that the lack of physical movement has become one of the most important challenges of modern health, especially in countries like Brazil, where millions of people do not even reach the minimum recommended levels of physical activity.

WHO points out main factors associated with cancer
The study conducted by the World Health Organization sought to map the relationship between cancer and modifiable lifestyle factors.
According to the data presented, smoking remains the main contributor to the global burden of the disease, representing 15.1% of the cases analyzed.
In addition, infections come right after, contributing 10.2% of the cancer burden observed in the survey.
Alcohol consumption holds another prominent position, being responsible for 3.2% of the cases.
However, the analysis was not limited to just these factors.
The WHO also evaluated elements such as high body mass index, insufficient physical activity, smokeless tobacco use, air pollution, and exposure to ultraviolet radiation.
Thus, the study offers a broader view of the risks influencing the development of different types of cancer.
Moreover, experts emphasize that knowing these factors is essential for building effective prevention strategies.
After all, identifying a risk is the first step to combating it.
Brazil reduces number of smokers, but faces growth in sedentary lifestyle
In recent decades, Brazil has become a global reference in combating smoking.
Educational campaigns, advertising restrictions, tax increases, and the creation of smoke-free environments have contributed to a significant drop in the number of smokers.
Currently, less than 10% of the Brazilian adult population smokes regularly.
This result is considered one of the greatest achievements of national public health.
However, while the country celebrates the reduction in smoking, another problem is growing silently.
According to a survey conducted by Quest, approximately 52% of Brazilians consider themselves sedentary.
Moreover, when the World Health Organization’s criteria are applied, the situation becomes even more concerning.
The data shows that about 76% of the population does not reach the minimum levels of physical activity recommended for health maintenance.
Consequently, millions of Brazilians live daily with the negative impacts of lack of movement.
And these effects go far beyond the loss of physical fitness.
Lack of physical activity increases health risks
Regular physical exercise is associated with a reduced risk of various diseases.
On the other hand, a sedentary lifestyle contributes to the increase in cardiovascular problems, diabetes, hypertension, and different types of cancer.
Furthermore, the absence of movement favors excessive weight gain, creating a cycle that can further compromise health.
In this context, another data point draws the attention of specialists.
Currently, about 30% of the Brazilian population is considered obese.
This number is concerning because obesity is associated with at least 13 different types of cancer.
Moreover, there is a direct link between obesity and low levels of physical activity.
For this reason, combating a sedentary lifestyle not only means improving quality of life but also significantly reducing the risk of serious diseases.
The magnitude of the problem goes beyond individual risk
Experts emphasize that the goal is not to downplay the risks of smoking or alcohol.
On the contrary.
Smoking remains one of the main factors related to cancer and deserves constant attention.
However, when analyzing public health, it is necessary to consider not only the intensity of individual risk but also the number of people exposed to it.
In this sense, Brazilian numbers are revealing.
While less than 10% of the population smokes, more than half consider themselves sedentary.
Moreover, three out of four Brazilians do not reach the minimum recommended level of physical activity.
Consequently, the collective impact of a sedentary lifestyle can be enormous.
Therefore, many experts consider promoting movement one of the greatest prevention opportunities of today.
Small changes can generate great benefits
Many people believe that combating a sedentary lifestyle requires radical changes.
However, the reality is different.
It is not necessary to become an athlete, run marathons, or spend hours in gyms to gain significant benefits.
On the contrary.
The change can start with simple actions incorporated into daily life.
Walking more, using stairs instead of elevators, standing up regularly during work hours, and reducing sitting time are examples of habits that help increase physical activity levels.
Additionally, playing with children, walking the dog, cycling, dancing, or engaging in any enjoyable activity also contributes to a more active routine.
Although structured physical exercise remains extremely important, experts emphasize that daily movement has equally significant value.
After all, the human body was designed to move.
And every step counts.
The silent risk that millions of Brazilians ignore
Unlike cigarettes, whose harmful effects are widely known by the population, sedentary lifestyle often goes unnoticed.
This happens because it integrates into the routine and ends up being seen as something normal.
However, the lack of physical activity produces significant health consequences over time.
Moreover, its effects usually appear gradually, making it difficult to perceive the problem.
For this reason, experts argue that combating sedentary lifestyle should occupy a central position in prevention policies.
While some risks are easily identified, others remain silent.
Sedentary lifestyle is one of them.
And, given the numbers presented by the WHO and the research conducted in Brazil, ignoring this problem could mean missing one of the greatest current opportunities to reduce diseases, improve quality of life, and prevent different types of cancer.
