Adequate physical activity helps reduce bone loss and is a fundamental way to stimulate bone formation, while low activity is prone to bone loss, so older adults maintain the necessary amount of exercise so that they can not only increase and maintain bone mass, but also reduce the risk of fracture. Of course exercise in the elderly should be measured and falls should be prevented. Passive exercise should be given to bedridden patients to reduce bone loss due to braking or disuse. Good lifestyle habits are also important to reduce bone loss, such as quitting smoking and drinking alcohol, drinking less coffee, and getting more light.
