Going on holiday is always a cause for celebration - and many travellers will toast the occasion with an alcoholic beverage before taking a nap on the plane.

But according to a new study - holidaymakers may want to reconsider this ritual.

German scientists have found the combination of in-flight alcohol and cabin pressure at cruising altitude may put strain on sleeping passengers' hearts.

They discovered that when people fall asleep after drinking alcohol at the low air pressures typically experienced during flights, blood oxygen levels drop and heart rates increase - even in those who are healthy and young.

"We were surprised to see that the effect was so strong," study co-author Dr Eva-Maria Elmenhorst told Sky's US partner network NBC News. "Please don't drink alcohol while being on an airplane."

Writing in the journal Thorax, the researchers said passengers with heart problems have an increased risk of aggravation of symptoms due to the decreased cabin pressure at cruising altitude, which is amplified during sleep.

Alcohol, often consumed on board, has similar effects, they said.

"The on board consumption of alcohol is an underestimated health risk that could be easily avoided," academics from the Institute of Aerospace Medicine in Germany said.

"It may be beneficial to consider altering regulations to restrict the access to alcoholic beverages on board."

For the study, researchers tested the impact of alcohol consumption and sleep in a hypobaric environment - one with low air pressure.

They assessed 48 people aged between 18 and 40 over two nights in two different environments - a sleep laboratory and an altitude chamber.

Participants consumed alcohol before one of the nights.

While young, healthy people most likely won't experience any serious harm to their hearts from drinking while flying, Dr Elmenhorst noted "the decreased oxygen saturation together with the increase in heart rate could exacerbate pre-existing medical conditions".
