On Sunbathing...

From Wikipedia:

Calcium is essential for living organisms, particularly in cell physiology, where movement of the calcium ion Ca2+ into and out of the cytoplasm functions as a signal for many cellular processes. As a major material used in mineralization of
bones and shells, calcium is the most abundant metal by mass in many animals. Approximately 99 percent of the body's calcium is stored in the bones and teeth.

Long-term calcium deficiency can lead to rickets and poor blood clotting and in case of a menopausal woman, it can lead to osteoporosis, in which the bone deteriorates and there is an increased risk of fractures.

While a lifelong deficit can affect bone and tooth formation,
over-retention can cause hypercalcemia (elevated levels of calcium in the blood), impaired kidney function and decreased absorption of other minerals.

However, a high calcium intake has been associated with a lower risk for kidney stones in more recent research. Vitamin D is needed to absorb calcium.

So... Should we start sunbathing at 12pm? Exchange student from overseas sitting under the hot sun at noon in the hostel garden... =.=
