How loneliness affects our health

The potentially harmful effects of loneliness and social isolation on health and longevity, especially among older adults, are well established.

For example, in 2013, I reported on research finding that loneliness can impair health by raising levels of stress hormones and inflammation, which in turn, can increase the risk of heart disease, arthritis, Type 2 diabetes, dementia, and even suicide attempts.

But people can be socially isolated and not feel lonely; they simply prefer a more hermetic existence. Likewise, people can feel lonely even when surrounded by lots of people, especially if the relationships are not emotionally rewarding.

Perhaps equally surprising is the finding that older adults are not necessarily the loneliest among us. Although most studies of the effects of loneliness have looked only at older people, Dr Holt-Lunstad, who with colleagues, has analysed 70 studies encompassing 3.4 million people, said that the prevalence of loneliness peaks in adolescents and young adults, then again in the oldest old.

Stop sleeping with your mobile phone

Anything closer than arm's length could cause cancer and infertility, health officials warn.

California Department of Health released guidance for reducing exposure to cell phone radiation on Thursday, amid mounting evidence that cell phone use may be linked to cancer, attention, mental health and reproductive health issues.

Cell phones transmit information using low frequency radio signals, which may expose us to unhealthy radiation, especially when streaming or downloading large files.

Research has not been able to prove definitively that cell phone radiation is dangerous, but there have been enough studies linking the two to warrant caution, especially for children, according to the health department press release.

Boy in China loses sight in eye after playing with desiccant dry pack

Desiccant packs, which are usually made up of silica gel grains, absorb water and are used to help food remain dry.

The accident happened when after finishing his snack, the boy, Keke, saw a small bag (desiccant dry pack) inside the snack box and took it out. He put the small bag (desiccant dry pack) into a drink bottle that contained  his beverage, after which the bottle exploded.

According to a doctor, Keke's right eye had been dissolved by alkaline liquid erosion, resulting in permanent blindness in that eye.

Lesson to be learnt:
Parents must remember to remove any desiccant packs found in any snack boxes just in case they cause problems to your kids. They may be harmless, but can be dangerous if mixed with wrong liquid.
