Crossfire on the health of Italians, especially the most fragile. Their fear is a combination between heat and Covid: “One increases the effects of the other and vice versa, with an immediate effect on symptoms such as headaches, fatigue and shortness of breath, and on the activity of the heart.” Bruno Trimarco, professor emeritus of cardiology at the Federico II University of Naples, explains it. “The night – he warned – certainly has a significant impact on patients affected by Covid, both in the acute phase and after the infection, on which we call Long Covid. In fact, on the one hand high temperatures increase the symptoms of infection, on the other hand can increase the stress on the heart, hit simultaneously by two lights, virus and heat together. ” How to protect yourself? No to ‘do it yourself’ supplements, yes to cold rain and drinking water even if you are not thirsty, reminds the expert.
Who is more dangerous
The most vulnerable people, such as the elderly, children and chronically ill people, are already vulnerable to heat and Covid respectively. “The scientific literature – analyzes Trimarco – has already documented that excessive heat represents a risk for the heart, causing chest pain, heart attacks and sudden death. When it is too hot, it can be a reduction in the the amount of blood pressure for the dilation of the blood vessels and the loss of excessive fluids that increase the risk of dehydration”.
For its part, Covid is also associated with symptoms common to those caused by heat, such as asthenia, mental fog, breathlessness and headaches. “Also – revealed the cardiologist – we know that Covid-19 causes many inflammatory processes that affect endothelial cells, i.e. the cells that line the heart and blood vessels. Among the effects produced are oxidative stress, inflammation, changes in heartbeats, the inability to pump blood and oxygen to other organs. Studies suggest that people with Covid, compared to those who are not infected, are at a greater than 55% risk of suffering a major cardiovascular event such as a heart attack, stroke or death.
Corrections
To avoid the effects of the summer-Covid combo, countermeasures are needed. Which? “No to ‘do it yourself’ additions, yes to cold showers or baths and to ‘planned’ water consumption: that is, do to drink at least one and a half liters of water during the day even if you don’t do. thirsty” , recommends Trimarco.
“Fatigue and weakness, symptoms common to Covid and excessive heat – note the cardiologist – can lead to stocking up on supplements. But mostly useless, at least against Covid. A study published in the journal ‘eClinicalMedicine’ promotes a mixture of natural substances, composed of arginine and vitamin C. Arginine is part of this amino acid naturally, which stimulates the production of nitric oxide, a key substance for the repair of the muscle work Vitamin C, on the other hand, thanks to a nanotechnology that optimizes absorption without side effects, antagonizes oxidative stress and improves muscle repair with beneficial effects on the heart and cascade effect on the whole body “.
Another tip: avoid going out if you test positive for Covid, both to avoid infecting others and to keep yourself safe from the heat outside; keep the house cool, using night air to refresh it, and during the day using locks or shutters and turning off as many electronic devices as possible; use light, loose clothing and curtains; avoid sugary, alcoholic or caffeinated drinks which can worsen symptoms and interact with medications in use.
