Walking is good for our health. That is what everyone knows. But how long do we have to walk to prevent diseases?
In a research, 500 people have taken physical activity meter with them 24 hours a day for more than 15 years to know how many steps they have to walk to prevent what kind of diseases.
They found out that there was a causal relationship between steps per day and occurrence of diseases, and there are 10 diseases which can be prevented by Walking.
(1) Cancer (2) Heart disease (3) Stroke (4) Type II Diabetes (5) High blood pressure (6) Cognitive impairment (dementia) (7) Depression (8) Osteoporosis (9) Fracture (10) Dyslipidemia (abnormal amount of cholesterol and/or fat)
Cognitive impairment (Dementia)
82 years old female works in her kitchen garden where some kinds of vegetables are grown in the morning earning about 3000 steps. In the afternoon, she goes for walking which earns about 2000 steps. She walks about 5000 steps a day and according to a test, her cognitive ability is as good as the one of 59 years old.
The number of steps to prevent cognitive impairment is more than 5000 steps including more than 7.5 minutes of activities which are moderate intensity such as fast walking or light field work.
More than 5000 steps a day and moderate-intense activity increase the blood flow of the brain, leading to activating the nerve activity of the hippocampus in the brain, which is associated with memory, resulting in the prevention of cognitive impairment.
