Households where both parents work are also pushing bedtimes later, with a lack of sleep raising fears of poor school performance and later life health woes.
It puts children at greater risk of developing mental health issues, catching viruses and becoming obese, according to past research. Studies have also linked a lack of sleep to low levels of emotional control.
Specialists fear the problem could worsen unless it is addressed now, and believe moves should be made to tackle it on the public health agenda.
Dr Catherine Hill, associate professor at the University of Southampton and consultant at Southampton Children's Hospital, told the BBC ahead of a Panorama Documentary on the topic: "If we continue to ignore emerging research evidence about the importance of sleep to health, we're potentially storing up problems for the NHS in future."
According to the Children's Sleep Charity, some 30 per cent of children will suffer with sleep issues during their childhood, costing the NHS millions of pounds in appointments.
Instead, changing bedtime routines, such as leaving phones and tablets out of bedrooms, could provide a solution.
Founder Vicki Dawson said: "We have been inundated with requests for support from families of children across the country, we can receive up to 200 emails every day.
"When families are sleep deprived it can lead them into crisis."
One aspect thought to be interfering with children's sleep is the blue light emitted by smartphones and tablets, which reduces the natural production of melatonin.

Excess blue light creates Reactive Oxygen Species (ROS) which results in inflammation, even during the day. It diminishes the function of mitochondria depleting the body of energy and also affects circadian rhythm, which controls every hormone in the body as well as all of the cellular growth and regeneration that happens during sleep. It ruins the internal clock affecting cellular growth and metabolism that can lead to diabetes, obesity, depression, and other modern-day diseases.
Later bedtimes in busy working households, and drinks high in sugar and caffeine are also thought to be worsening sleep deprivation.
More than 8,000 children under 14 were admitted into hospital in 2016 with a primary diagnosis of sleep disorder - up from below 3,000 in 2006. The number has steadily increased year-on-year for nearly two decades.
Figures also show the number of prescriptions in England for melatonin rose to nearly 600,000 in 2015.
