London, Sep 20 : There is a need to ban the sale of caffeinated energy drinks to children and young people to tackle obesity and mental health problems, says an expert.
Caffeine is probably the most commonly used psychoactive drug across the world as it increases activity and heightens attention and awareness.
But caffeine also increases anxiety, reduces sleep and is linked with behavioural problems in children, said Russell Viner, Professor from the UK's Royal College of Paediatrics and Child Health (RCPCH).
Recent studies have also showed that it may have concerning effects on the developing brain.
This is alarming because psychological distress can lead to risky behaviours like drug use and poorer academic attainment, Viner said.
"It's time to bring in laws to ban the sale of caffeinated energy drinks to children and young people to tackle the twin epidemics of obesity and mental health problems," he stated, in the new study published in the journal The BMJ.
The high sugar content in many of the energy drinks (as much as 27g of sugar per 250ml serving) "undoubtedly contributes to the overall calorie excess and resultant obesity epidemic among our children".
But perhaps most concerning are the effects on sleep, Viner said, because research has established a clear inverse association between caffeinated energy drinks and sleep duration.
Children and young people in high income countries consume more sugar and calories than required and are therefore unlikely to need additional energy.
This combined with regular caffeine consumption is causing concern as there is little evidence of the effect caffeine could potentially have on the developing body, Viner said.
Instead of binging on energy drinks, humans can get energy naturally from a "good diet, refreshing sleep, exercise and, most importantly, interaction with other people".
While government's consultation must drive a search for improved evidence, "there is now sufficient evidence to act to protect children", Viner noted.

New Delhi (PTI): Thirteen of the world's top 20 most polluted cities are in India, with Byrnihat in Assam topping the list, according to a new report published on Tuesday.
The World Air Quality Report 2024 by Swiss air quality technology company IQAir said Delhi remains the most polluted capital city globally, while India ranked as the world's fifth most polluted country in 2024, down from third in 2023.
The report said India saw a 7 percent decline in PM2.5 concentrations in 2024, averaging 50.6 micrograms per cubic metre, compared to 54.4 micrograms per cubic metre in 2023. Yet, 13 of the world's 20 most polluted cities are in India.
Air pollution in Delhi worsened, with the annual average PM2.5 concentration rising from 102.4 micrograms per cubic metre in 2023 to 108.3 micrograms per cubic metre in 2024.
The Indian cities in the world's top 20 most polluted cities are Byrnihat, Delhi, Punjab's Mullanpur, Faridabad, Loni, Gurugram, Ganganagar, Greater Noida, Bhiwadi, Muzaffarnagar, Hanumangarh and Noida.
Overall, 35 percent of the Indian cities reported annual PM2.5 levels exceeding 10 times the WHO limit of 5 micrograms per cubic metre, the report said.
The high level of pollution in Byrnihat, a town on the border of Assam and Meghalaya, is due to emissions from local factories, including distilleries, iron and steel plants.
Delhi grapples with high air pollution year-round and the problem worsens in winter when unfavourable meteorological conditions, combined with vehicular emissions, paddy-straw burning, firecrackers and other local pollution sources, make the air quality hazardous.
Air pollution remains a serious health risk in India, reducing life expectancy by an estimated 5.2 years.
According to a Lancet Planetary Health study published last year, about 1.5 million deaths in India every year from 2009 to 2019 were potentially linked to long-term exposure to PM2.5 pollution.
PM2.5 refers to tiny air pollution particles smaller than 2.5 microns, which can enter the lungs and bloodstream, leading to breathing problems, heart disease and even cancer. Sources include vehicle exhaust, industrial emissions and the burning of wood or crop waste.
Former WHO chief scientist and health ministry advisor Soumya Swaminathan said India has made progress in air quality data collection but lacks sufficient action.
"We have the data; now we need action. Some solutions are easy like replacing biomass with LPG. India already has a scheme for this, but we must further subsidise additional cylinders. The first cylinder is free, but the poorest families, especially women, should receive higher subsidies. This will improve their health and reduce outdoor air pollution," she told PTI in an interview.
In cities, expanding public transport and imposing fines on certain cars could help. "A mix of incentives and penalties is necessary," she said.
"Finally, strict enforcement of emission laws is crucial. Industries and construction sites must comply with regulations and install equipment to cut emissions instead of taking shortcuts," the former director general of the Indian Council of Medical Research added.
