the hazardS of dream loss revealed
A silent epidemic of dream loss may be at the root of many illnesses attributed to sleep deprivation, say scientists, suggesting that the unrecognised public health hazard may contribute to depression, a study claims. Researchers detailed the various factors that cause rapid eye movement (REM) sleep and dream loss. Typical sleep follows a pattern in which deeper, non-REM sleep is prioritised by the body. Only later in the night and into the early morning do people experience dreaming, during REM sleep. “We are at least as dream-deprived as we are sleep-deprived. Many of our health concerns attributed to sleep loss actually result from REM sleep deprivation,” said Rubin Naiman, assistant professor at University of Arizona in the United States. He sees REM dream loss as an unrecognised public health hazard that silently wreaks havoc by contributing to illness, depression and an erosion of consciousness.
ancient ink could treat cancer
A plant-based ink, that has been used by Chinese calligraphers for hundreds of years, could non-invasively kill cancer cells, scientists claim. As cancer cells leave a tumour, they frequently make their way to lymph nodes, which are part of the immune system. In this case, the main treatment option is surgery, but this can result in complications. Photothermal therapy (PTT) is an emerging non-invasive treatment option in which nanomaterials are injected and accumulate in cancer cells. A laser heats up the nanomaterials, and this heat kills the cells. Many of these nanomaterials are expensive and toxic. A traditional ink called Hu-Kaiwen has similar properties as the nanomaterials.
Urban men and hypertension
According to a report of the National Institute of Nutrition (NIN), men in urban areas suffer more hypertension than women and its prevalence is highest in Kerala. It also mentions that nearly 16 per cent of men in the country smoke tobacco and 30 per cent consume alcohol. A study on these aspects was conducted by the National Nutrition Monitoring Bureau. The findings of the study formed the basis of a report compiled by NIN, which comes under the Indian Council of Medical Research). The report, titled ‘Diet and nutritional status of urban population in India and prevalence of obesity, hypertension, diabetes and its associated non-communicable diseases’, was released last week. As per the report, around 31 per cent of urban men suffer from hypertension as compared to 26 per cent women.
