Vacations are over. Heat is over. Work is coming full circle again. First colds are back, and Italian health care is preparing to support the new flu wave, and with it the new Sars-19 spike that is likely to be in winter, like all flu spikes.
Recent studies by Italian groups have shown a relationship between low vitamin D levels and COVID onset, especially in populations in northern Italy. Could this be a possible contributing cause (along with particulate pollution that acted as a vehicle for the virus) of why Northern Italy was so plagued by COVID in the first and second waves? In fact, the last 30 years in Italy have seen a real global decline in vitamin D levels. The cause of this phenomenon is, as always, multifactorial.
1)The change in the tilt of the Earth’s axis is related to the change in the rotation of the two poles (instead of north to south currently to the east) which is in turn influenced by the ongoing climate change (the Earth’s axis is responsible for the seasons) and which is responsible for the reduced ability of the sun in our latitudes to fix Vitamin D.
2)The insufficient use of the foods available in the Italian territory of vitamin supplementation.
3) Fish from our seas, being very lean, have lower levels of vitamin D than those found in fish from the northern seas.
4) Vitamin D plays an important role in modulating the immune system, and so its deficiency may be associated with an improperly adapted immune system.
Vitamin D deficiency is also often found in young adolescents, students, complicit in the closing of recent years.
Therefore, a proper assessment of vitamin D level is definitely indicated not only in post-menopausal women, but in general also in a population poorly exposed to the sun and sedentary, in order to improve our body’s ability to respond to infections that we will have to live with for a long time.
