A good way to get these benefits is to perform weight-bearing physical activity -- in other words, any activity in which your body works against gravity. Sure, you could hit the gym. But you don't necessarily have to pump iron to reap these rewards. Walking, dancing, climbing stairs and playing tennis can all accomplish the same goal. Likewise, you might want to try yoga and tai chi, which also have bone-sustaining moves.
As if you needed another reason to stub out that cigarette: Smoking lowers the amount of estrogen in your body. Since estrogen is a hormone that can help slow bone loss, lower levels of it can lead to osteoporosis.
As with smoking, heavy drinking is a vice that can eventually take a toll on your bone strength. While research has shown some benefits of an occasional glass of wine, it's good to limit yourself to no more than one alcoholic drink per day. This is because alcohol can make it harder for your body to use the calcium you take in. Also, too much at one time can affect your balance and lead to falls.
In addition to ensuring that your bones are strong, it may be worth it to accident-proof your home to reduce your chances of falling. One simple thing that goes a long way is to use a rubber bath mat in the shower or tub. Keep your floors free from clutter, and remove throw rugs on which you can trip. You may also want to make sure that you have grab bars in the bath or shower.
For some women, medicines to prevent bone loss may be the right answer. Talk with your doctor or nurse about the risks and benefits of medicines for bone loss.
