Air-purifying mask lets you breathe easily; your napping and viewing habits may be increasing your risk of depression

In the run-up to this year’s IFA trade show in Berlin, LG has announced that it will be presenting a wearable smart mask that filters air pollution and may also eliminate germs and viruses.

The air-purifying mask is equipped with two H13 HEPA filters, which can be removed and replaced as needed. In fact, when this is the case, the mask sends a notification directly to the wearer’s smartphone via the LG ThinQ mobile application.

With the new mask, LG claims that its customers will be comfortably able to breathe air that is clean and healthy for a period of up to eight hours. Along with filters, the device is equipped with ultraviolet LEDs to kill germs, and it is also able to adjust to the volume of air inhaled and exhaled by the user, with twin fans that speed up and slow down to facilitate easy breathing. For added convenience, the mask’s integrated battery can also be recharged directly in the special case that will ship with the device.

With regard to its environmental impact, LG is keen to point out that all of the components in the PuriCare Wearable, from the filters to the headband, can easily be replaced and are fully recyclable. Availability or pricing information has not yet been announced for the new mask, which is expected to go on sale in late 2020.

Sleep and viewing patterns can harm your health

While the coronavirus pandemic poses a prolonged and unique challenge to public mental health, researchers from Massachusetts General Hospital have identified more than 100 modifiable factors that could prevent depression in adults.

The study, published in The American Journal of Psychiatry, aims at providing “the most comprehensive picture to date” of modifiable factors that might be associated with the risk of developing depression. Among them are lifestyle behaviours such as sleep patterns, diet, exercise, media intake, environment and socialising.

“Depression is the leading cause of disability worldwide, but until now researchers have focused on only a handful of risk and protective factors, often in just one or two domains,” noted Dr Karmel Choi, investigator in the Department of Psychiatry and the Harvard T H Chan School of Public Health, and lead author of the paper.

In order to do so, researchers drew on a database of over 100,000 participants in the UK Biobank cohort study to systematically scan and evaluate which modifiable factors may have a causal relationship to depression risk.

Surprisingly, the tendency for daytime napping and regular use of multivitamins appeared to be associated with depression risk, though the study points out that more research is needed to determine how these might contribute.

An additional factor associated with depression risk is the time spent watching TV, which tremendously increased in reaction to the coronavirus-induced stay-at-home orders.

The authors of the study note that additional data is necessary to determine if that risk was due to media exposure per se or whether time in front of the TV was a proxy for being sedentary.

Meanwhile, researchers found that socialising with other people is a behavioural factor that could prevent depression, and even for people highly prone to depression due to either genetics or early-life traumas. “Far and away the most prominent of these factors was frequency of confiding in others, but also visits with family and friends, all of which highlighted the important protective effect of social connection and social cohesion. These factors are more relevant now than ever at a time of social distancing and separation from friends and family,” said Jordan Smoller, associate chief for research in the MGH Department of Psychiatry, and senior author of the study.
