We know the excessive usage of tablets and phones would damage our health in a bigger aspect. Although many people know many disadvantages of looking at these screens, they never stop it. This is happening mostly among young people, which results in many adverse health effects. Therefore, there should be some regulations that one has to adapt in order to avoid these problems in future.
A numerous number of studies are being done at various universities and health institutions to understand diverse health effects of watching screens for many hours. In this perspective, a research team in Barcelona Institute for Global Health (ISGlobal) studied whether there is a link between use of screens at night with the development of breast and prostate cancer. Their main aim is to check if blue light from screens could result in these cancers. Their researcher was influenced by the WHO’s classification.
"WHO's International Agency for Research on Cancer (IARC) has classified night shift work as probably carcinogenic to humans. There is evidence pointing to an association between exposure to artificial light at night, disruption of the circadian rhythm, and breast and prostate cancers. With this study, we sought to determine whether night exposure to light in cities can affect the development of these two types of cancer,". Blue light is a range of the visible light spectrum emitted by most white LEDs and many tablets and phone screens.

Martin Aubé, studied this as he knows melatonin production and secretion can be decreased by artificial light at nights that depends on intensity and wavelength, especially blue light. The study was undergone with data from about 4,000 people aged between 20 and 85. There was an indoor and outdoor study that was taken in Madrid and Barcelona which was determined through nocturnal images.
Results obtained for both cities show that participants exposed to higher levels of blue light had a 1.5 and 2-fold higher risk of developing breast and prostate cancer, respectively, as compared to the less-exposed population.

Researchers want to develop this study and understand rigorously by using data of individuals, especially younger ones who use blue light emitting screens extensively. Whether or not the study proves the statement, we should keep in mind that extensive usage of screens that emit blue lights could spoil our health.
