NaturaThe use of scented cleaning products can lead to the formation of nanoparticles in indoor air, especially when used together with ozone-generating devices. These particles are able to penetrate deep into the lungs, so it is important to ventilate rooms regularly and choose cleaning products with minimal fragrance content.
VigorEngineers at the University of California have developed a device capable of generating energy at night by harnessing the temperature difference between the ground and outer space. This technology could provide ventilation for greenhouses and buildings without the need for fuel.
NaturaThe study found that radiation levels in Russian apartment buildings are generally low, but in some cities, they are noticeably higher due to construction materials and ventilation features. Newer buildings often have increased background radiation; however, this does not pose a significant health risk to residents.
SalusA new study has shown that the risk of transmitting influenza decreases with good ventilation and when infected individuals are not coughing. The greatest danger arises during close contact in poorly ventilated spaces.
