He who takes 10,000 steps a day will stay healthy. A meta-analysis shows that even shorter walks are sufficient. How much should we walk a day?
Movement is healthy - this is known and always emphasized. Even a simple walk contributes a lot to better blood circulation, improves metabolism, strengthens the immune system and prevents chronic diseases.
While calories used to be counted, today steps are counted, more precisely: 10,000 steps a day. Until now, it was believed that anyone who walks that many steps a day - depending on the length of the steps, about six to eight kilometers - stays in good shape and is in better health.
Meta-analysis disproves the 10,000 step theory
For a long time, scientists have doubted this supposed magical value of 10,000 steps. A new meta-analysis published in the European Journal of Preventive Cardiology now shows that even less than 4,000 steps per day is enough to reduce the risk of early death. According to this analysis, even 2,300 steps per day are enough to reduce the risk of death from cardiovascular diseases.
The researchers analyzed a total of 17 different studies and had access to the data of over 227,000 people from different parts of the world. They found that daily walking is strongly associated with the best chances of living longer and healthier – regardless of age, gender or place of residence.
Basically, the more you walk, the better. Just 1,000 steps a day reduces the risk of premature death by 15 percent, this analysis shows. Whereas with 500 steps, the risk of fatal heart diseases decreases by seven percent. From 4000 and more is therefore considered as an ideal length per day to largely eliminate the risks of cardiovascular diseases.
The 10,000 step rule comes from marketing
These are the latest data from meta-analyses on movement and health. While the rule of 10,000 steps per day has never been scientifically proven. Scientists think that this probably stems from the marketing strategy of a Japanese company, made for its own purposes.
In 1964, at the time of the Olympic Games in Tokyo, the Yamasa company introduced the first instrument for measuring steps, called "Manpo-kei" - which means "10,000 step counter". This number of steps keeps people in shape and is an expression of a healthy lifestyle, the manufacturer explained at the time. This thesis quickly became a general recommendation - but it has now been rejected. According to recent analyses, even fewer steps per day are enough, but daily movement is important./ DW
