According to Delamare, people who drink too much alcohol can be left feeling “drowsy and sleep-deprived” come the morning.
But, what could surprise you, is how many drinks can contribute towards a bad night of sleep.
Delamare says that people drinking more than six units in one sitting, which is categorised as “binge drinking” in the UK, are at the most risk of losing vital hours snoozing.
Six units of alcohol translate to two pints of five percent strength beer, or two large glasses (250ml) of 12 percent wine.
However, there is some evidence to suggest that even one alcoholic drink could be detrimental to rest.
A 2018 study found that alcohol can significantly affect sleep quality, regardless of unit consumption.
The researchers analysed the sleep and alcohol habits of more than 4,000 adults between 18 to 65-years-old.
Findings revealed that low alcohol intake reduced sleep quality by 9.3 percent, moderate alcohol intake reduced sleep quality by 24 percent and heavy alcohol-reduced sleep quality by nearly 40 percent.
