I have noticed that there are actually books with titles like "Sitting is the New Smoking" and studies are cited suggesting that excessive sitting can be associated with various health risks. Like many topics, there is room for interpretation here, and sitting per se is not necessarily harmful. (And certainly not comparable to smoking)
The Effects of Modern Lifestyle
The modern lifestyle has led to many people spending more and more time sitting. Although we, as humans, are not evolutionarily designed to spend the majority of the day sitting, it is still possible to minimize the negative effects. The purported negative effects of sitting are often associated with a lack of physical activity and other lifestyle factors.
One main cause of potentially negative effects of sitting lies in the general lack of movement. When we remain in one position for an extended period, our muscles remain inactive, and our calorie expenditure remains low. This can lead to weight gain, muscle atrophy, and an increased risk of chronic diseases such as diabetes and cardiovascular diseases.
Even the sitting posture itself is not necessarily a problem. Many people tend to sit in a poor posture, which can lead to tension, back pain and other muscular problems. However, the issue lies not only in the sitting posture but often in overall muscle weakness as well. Regular strength training can help strengthen these muscles.
The Importance of Movement and Fitness in Everyday Life
The solution for a healthy lifestyle is not simply to avoid sitting altogether. Instead, it is about finding a healthy balance and incorporating regular physical activity into daily life. One way to achieve this is to take a short break every hour to stand up, stretch, and take a few steps. These brief interruptions can stimulate blood flow, increase muscle activity and reduce bodily strain.
And even if you now spend hours standing in the office instead of sitting, that doesn't automatically mean it's better for your fitness. Instead of solely focusing on avoiding sitting, we should also keep other aspects of fitness in mind.
Cardiovascular training, such as jogging, swimming, or cycling, strengthens the cardiovascular system and improves endurance. Strength training is crucial for maintaining muscle strength and bone health. A balanced combination of cardiovascular and strength training, along with a healthy, balanced diet, is essential for promoting a healthy lifestyle.

Closing Words
I haven't read any of the books with titles like "Sitting is the new smoking" and perhaps their content isn't quite as dramatic and they might just recommend a more active lifestyle. But the fact remains that the misleading title alone sticks in many people's minds. And that's exactly how misinformation is born. You can sit if you want to, as long as you also engage in regular physical activity and maintain an active lifestyle. And of course, it's always advisable to avoid smoking, as it is proven to be harmful to health.
