People in the age group of 35-50 are not able to cope with the effects of heavy drinking as well as youngsters in their twenties.
It is so because as the body gets older it loses muscle and piles on fat, which increases the effects of alcohol.
"As a person gets older, less body water and more fat in the system means alcohol stays in the blood stream for longer, which helps explain why people often experience the effects of heavy drinking more than they might have done if younger," The Sun quoted a spokesman for Alcohol Concern, as saying.
Now, a YouGov poll has substantiated this fact.
The poll found that almost half of 30 to 50-year-olds admitted to sometimes drinking too much and didn't know when to stop.
The poll also revealed that one in three of respondents said that drinking too much had ruined a night on the town at least once in the last year and 44 per cent said that they did not stay within the recommended limit.
General Practitioner Dr Sarah Jarvis said over-30s should be careful during the holiday season.
"You often hear people saying they feel worse after drinking the older they get - as you age, the body isn't as good at dealing with alcohol," she said.
"To help you stick to your limits, you might want to try agreeing a limit with a friend, following one alcoholic drink with a soft drink, or taking time out from drinking for another activity," she added.
