5 daily habits that weaken the bones and how to keep them strong

Bones function as our body's main supporting structure. It goes without saying that our bones need to remain healthy, because they enable movement and balance, while providing overall body strength. Some regular everyday activities, otherwise perceived to be harmless, leads to bone weakening that can end up in fractures, and injuries. Simple changes in our daily habits however, can help us maintain healthy bones for extended periods of life. Here are 5 everyday activities that damage bone health, along with ways to protect it...

Not only is sitting the new smoking, long periods of sitting during daily activities, also causes damage to bone strength. Bone density needs weight-bearing activities, to stay dense and strong. Long periods of sitting whether at work, watching television or using your phone, strip bones of their necessary mechanical tension that signals density maintenance. The prolonged absence of mechanical stress causes bones to become brittle, until they eventually break, more easily particularly in hip and spinal regions.

How to keep bones strong: Make movement part of your day. Use your breaks to stand up and walk around at least once per hour, while choosing stairs over elevators and including weight-bearing activities such as walking, jogging, dancing or strength training in your exercise routine. Bodyweight exercises such as squats and calf raises, serve as effective ways to build stronger bones in the long-term.

The consumption of sugary soda, along with caffeinated beverages results in bone calcium depletion. Phosphoric acid, found in many sodas, functions as an element which blocks the absorption of calcium by the body. Excessive caffeine consumption too, accelerates calcium elimination through urine which leads to weakening of bones throughout the years. Drinking these beverages instead of calcium-rich drinks like milk, further reduces your bone’s nutritional support.

To protect your bones, limit your consumption of soda and energy drinks and coffee drinks to reasonable levels. Substitute one daily sugary drink with either calcium-enriched milk, herbal tea or plain water. You can add lemon slices to your water, to get a refreshing taste without causing harm to your bones.

The body needs vitamin D which is also known as the “sunshine vitamin” to effectively absorb calcium. A vitamin D deficiency stops calcium from food to reach its full potential, in maintaining bone health. A combination of indoor living, or limited sunlight exposure in your area, can result in vitamin D deficiency that causes weakened bones together with muscle weakness.

How to keep bones strong: Devote 10-20 minutes to sunlight exposure during early morning or late afternoon periods. Your diet should contain vitamin D-rich foods, including fatty fish with fortified dairy products and eggs. You should consult your doctor about vitamin D supplements when necessary.

The human body suffers damage from smoking, because it harms almost all its organs including bones. Smoking causes reduced blood circulation to bones, while simultaneously disrupting the manufacturing process of cells that build bone tissue. When you drink excessive amounts of alcohol, your body experiences disturbances in calcium levels and bone-protecting hormone production. The combination of these behaviors, raises your chances of bone fractures, and prolongs recovery periods when injuries occur.

How to keep bones strong: If you smoke, seek support to quit. Men and women should limit their alcohol consumption as much as possible. Your health condition and well-being improve through a better lifestyle choice.

Healthy bones require multiple essential nutrients, beyond calcium. High salt consumption triggers the body to release calcium, thus weakening the bones. The lack of proper diet with not enough fruits and vegetables, together with inadequate calcium-rich food consumption leads to progressive bone density loss. The bones require essential nutrients including magnesium, vitamin K and protein for strength maintenance, although people frequently ignore these components.

Strong bones require a diet that combines balanced intake of fruits and vegetables with dairy products, fortified plant milks and lean proteins, nuts and seeds. Processed foods with high salt content should be avoided.
