Everything you need to know before heading into dry January: why it could be bad for your health

Millions of people around the world will wake up today with a smelly hangover and a New Year’s resolution to cut down on their alcohol consumption.

It is estimated that more than one in seven Americans and Britons will experience Dry January this year – which has been linked to better sleep, mood and athletic performance.

While experts agree that giving the body a break from alcohol has many health benefits, doctors warn that for many people, it can do more harm than good.

For example, those who attend can swamp the following month – dubbed “Wet February” – or use it as an excuse to drink heavily for the rest of the year.

Meanwhile, alcoholics who are physically dependent on the drug are urged not to stop drinking without expert help, as they could experience seizures.
