Why winter is favourable to coronavirus and weakens the immune system
Many types of viruses thrive in favourable conditions in winter. They can survive for long periods in the dry, cold air, and people spend more time indoors. On the other hand, our immune system weakens due to the dry air and lack of sunshine. This combination makes coronavirus and other pathogens more dangerous in winter than in summer. However, humidifiers and air purifiers can help to keep us healthy throughout the cold months.
