During the coronavirus lockdown, we have been told to stay indoors.

On sunny days, however, it’s worthwhile venturing outside for exercise and exposure to sunlight, which gives us natural Vitamin D. This was something everyone used to know in the old days.

Vitamin D is fat soluble, which means it is stored in our fat cells. Other commonly touted vitamins, such as B and C, are water soluble (e.g. expelled in urine) and must be taken daily.

Vitamin D might also help to prevent respiratory infections, which could include coronavirus, according to an Australian researcher.

New American has the story, ‘Sunshine Increases Vitamin D and May Build Resistance to Coronavirus’. Excerpts follow, emphases mine:

The researcher, Dr. Rachel Neale, said during an interview with The Australian last week that having low levels of Vitamin D increases vulnerability to viral infections, including COVID-19.

“Now, more than ever, is not the time to be vitamin D deficient,” Dr. Neale said. “It would make sense that being vitamin D deficient would increase the risk of having symptomatic COVID-19 and potentially having worse symptoms. And that’s because vitamin D seems to have important effects on the immune system.”

Last year, Neale headed up a study of 78,000 patients, and found that people with low levels of Vitamin D are almost twice as likely as those with high levels of vitamin D to develop acute respiratory infections, which people with COVID-19 are now dying from

Neale found that Vitamin D supplementation reduced the risk of acute respiratory infections, but she does not take Vitamin D tablets herself, as she believes time in the sun provides more benefits. However, she accepts that oral supplements are useful for people who cannot spend time in the sun.

Get outdoors now and then, especially when it’s sunny.

Vitamin D deficiency has also been linked to depression. Therefore, spending some time in the sun does a tremendous amount to lift one’s mood.

Because it is fat soluble, getting Vitamin D now during the warmer, sunnier months will provide physical and psychological benefits during the colder seasons when we stay indoors.

As always, there is no need to overdose and get a sunburn. Even exposure of 15 or 20 minutes a day can help.
