This allows warm blood to cool off, releasing heat as it travels near the skin, Casey said.

Teenagers’ late-night mobile phone use is harming their sleep and potentially their mental health, say researchers who advised that “physical boundaries” be set over use of such devices in the bedroom. A longitudinal study of 1,101 Australian high school students aged between 13 and 16 found poor-quality sleep associated with late-night texting or calling was linked to a decline in mental health, such as depressed moods and declines in self-esteem and coping ability. Lead researcher, Lynette Vernon of Murdoch University in Perth, said her findings were evidence of the need for curfews for teenagers to be established around use of devices in their bedrooms.

Many of us have had the experience of struggling to fall and stay asleep during a heat wave — especially if we don't have air conditioning. This side effect of climate change will disproportionately affect certain demographics — specifically, people who can't afford to run their air conditioning all night, and the elderly, who have a harder time regulating their body temperature.
