The human skin absorbs Vitamin D from sunlight and utilizes it to synthesize Calcium and Phosphorous in the body. Thus Vitamin D is also called "Sunshine Vitamin." It’s a fat-soluble vitamin and is of three types: D-1, D-2, and D-3. Vitamin D maintains the levels of calcium and phosphate in the body. These nutrients are necessary for strong bones, teeth, and muscles and increase the body’s resistance to fight against diseases. Vitamin D has anti-inflammatory property that helps to shorten the duration and adverse effects of infections.
Some of the other significant benefits of Vitamin D include:
Nations across the globe imposed lockdowns and shutdowns to prevent the spread of the COVID-19 virus. People were restricted from moving outside, and only essential survival items like food and medicine were available. The lockdown also brought many reforms in working culture, which was earlier thought possible in the next 40-50 years. Work from Home is now being applied by all of the service-based companies around the globe. Companies are making policies where employees can work from anywhere they like (Thanks to the internet). Work from home promotes social distancing, prevents the rapid spread of the virus, and saves people's lives without hampering the business's growth.
However, this entire concept of home quarantine or lockdowns for longer durations can trigger Vitamin D deficiency in the body. People staying indoors for a longer duration do not get enough sunlight. The skin needs sunlight to synthesize Vitamin D, which is very much essential for our body. Daily intake of vitamin D in the diet helps strengthen our bones and teeth and keeps our immune cells healthy.
A recent study by David O. Meltzer et al. published in the JAMA open network journal on September 3, 2020, discovered a correlation between vitamin D deficiency and a higher risk of COVID-19. Vitamin D levels decrease when there is an ongoing inflammation in the body rather than stating that low vitamin D levels predispose the body to severe infection. Older people, obese people, patients with heart disease, people who drink too much alcohol suffer from low levels of Vitamin D. This is also interesting to note that such risk factors are also applicable for COVID-19. However, there is not enough evidence yet to say that Vitamin D supplements can reduce the risk of COVID-19.
Thus patients who have recovered from COVID-19 and normal healthy people who are staying indoors for a longer duration of time must maintain their Vitamin D levels to lead a healthier life.
Here are certain tips to maintain your Vitamin D level in the body.
