Calcium is a mineral most abundantly found in the human body. It is the main constituent of the skeleton and helps in the formation and maintenance of our bones and teeth. Calcium plays a significant role in the contraction of muscles and secretion of certain hormones and enzymes. Expansion and contraction of blood vessels is dependent on calcium. It plays an important role in the clotting of blood. In short calcium is necessary for good health of our body. Therefore it should be consumed in sufficient amounts regularly.

Calcium is present in most dairy products and also in eggs, leafy vegetable, nuts, legumes and whole grains.The digestive system breaks down the calcium consumed, and facilitates its absorption in the body. Vitamin D plays a crucial role in the absorption of calcium. Major part of the absorbed calcium is stored in the bones, and the remaining is present in blood. Hence the short term calcium deficiency can be balanced by using up the calcium stored in the bones. But if this deficiency lasts longer, the calcium in the bones start depleting and it can lead to various health problems. Let’s see what are some calcium deficiency symptoms.

Calcium Deficiency Symptoms
Early Signs and Symptoms
Calcium deficiency in a person can be easily detected by observing his nails and skin. Inadequate calcium levels in the body make the nails brittle and the skin dry. Yellowing of the teeth also signals calcium deficiency. The early signs of calcium deficiency are muscle cramps, eye twitching, leg tensions, weakness, muscle aches and sleep disorders. Sweating in cold weather is also a symptom of low calcium levels. If these symptoms are not identified at the right time, prolonged calcium deficiency may lead to other health problems.
General Calcium Deficiency Symptoms
Calcium deficiency is mainly associated with skeletal abnormalities. The bones become brittle and are prone to fracture. It causes reduced bone density making them thinner and weaker. If ignored in the early stages, it can lead to several bone disorders like osteopenia, osteoporosis and osteomalacia. There are some less common symptoms of calcium deficiency like hypertension, kidney stones, unusual menstrual cramps and miscarriages. Read the rest of this entry »
Global warming, nuclear waste, pollution, extinction of species… the list of global environmental issues, which is already quite a long one, continues to grow in length. Most of us seem to have become quite involved in our personal lives, and hence, are not at all aware about the current environmental issues, while others know about them, but prefer to carry on with their it-won’t-affect-us attitude. The end result, the list is just growing longer and longer, while we run out of time to solve these global environmental problems.
Global Environmental Issues List
If asked what are the global environmental issues that the planet faces today, most people out there wouldn’t be able to go beyond global warming and energy crisis. These people are not aware of the fact that there are several other issues of global concern, each of which is equally hazardous. More importantly, all these issues are related with each other by some or the other way, and hence, tackling them one by one has just become difficult.
Climate Change: Climate change has become more than obvious over the past decade, with nine years of the decade making it to the list of hottest years the planet has ever witnessed. The rise in temperature has also ensured that the equations on the planet have gone for a toss. Some of the most obvious signs of this include irregularities in weather, frequent storms, melting glaciers, rising levels of sea etc. Going by the prevailing conditions, it is not difficult to anticipate that the planet is heading for a dramatic climate change, somewhere in near future.

Conservation of Species: Yet another global environmental issue, species conservation basically deals with conservation of flora and fauna, in order to curb the extinction of species. Extinction of a single species of plant or animal results in a dramatic imbalance in the ecosystem, as a number of other species dependent on it directly or indirectly are also affected. Over the last century or so, several plants and animal species have become extinct thus resulting in a major loss for the biodiversity of the planet.
