How 8 hours’ sleep is POINTLESS unless you have a regular bedtime
Not going to bed and waking up at the same times every day might carry as many health risks as not getting enough sleep
GETTING a good night’s sleep is important…but it doesn’t mean a thing if you don’t have a regular bedtime.
At least, that’s the conclusion of a new study which says that catching those hard-fought eight hours kip is irrelevant if you go to bed and wake up at different times regularly.
There’s a tonne of research to suggest that sleep deprivation can heighten our chances of getting fatter and developing type 2 diabetes, insulin resistance, high blood pressure and heart disease.
A two-year worldwide study conducted by the National Sleep Foundation found that teens needed between eight and ten hours a night, while adults really should be aiming for between seven and nine.
But the NHS has said that it’s the quality and regularity of those hours that matters – and that regular poor sleep can shorten your life expectancy.
“An occasional night without sleep makes you feel tired and irritable the next day, but it won’t harm your health,” the NHS said.
“If it continues, lack of sleep can affect your overall health and make you prone to serious medical conditions, such as obesity, heart disease, high blood pressure and diabetes.”
Scientists from Duke University Medical Center looked at the sleeping patterns of almost 2,000 adults aged 54-93 who had no previous history of sleeping disorders to establish the link between bedtime patterns and the calculated 10-year risk of developing various diseases.
They all wore sleep tracking devises for seven days and kept sleep diaries.
Experts found that those volunteers with irregular bedtimes had a higher body mass index (BMI), higher levels of blood sugar, higher blood pressure and were more likely to have a heart attack or stroke in the following decade than those who had regular sleep patterns.
