GAMERS
Playing video games may be the best way to
wind down, researchers at University College
London have found. People who played a
smartphone puzzle game for 15 minutes a er
work were more relaxed, more energetic,
and less stressed than those who were given
fidget spinners or mindfulness apps to use.OPTIMISTS
Being a glass-half-full person may help us to
sleep be er, a study at the University of
Illinois has found. A survey of more than
3,500 people aged 30 to 50 found that those
who rated themselves as optimistic were 78
per cent more likely to report good sleep.FREQUENT FLYERS
Planning a ight? Make sure you’re buckled
up tight! Changes in the jet stream thanks to
climate change are leading to more
turbulence. Researchers at Reading
University estimate that severe turbulence
could rise threefold in the next 50 years.FAT CATS
We’re not the only ones that are prone to
middle aged spread. Researchers in
Toronto have found that pet cats pile on
the pounds as they age, peaking at eight
years old. They suggest that cat owners
regularly pop their moggies on the scales
to make sure they are a healthy weight.Bad month
