Many of us overindulge at Christmas. We meet friends at the pub, crack open the wine with family, and make the most of free fizz with your colleagues at work parties. And although many of us drink too much from time to time - and regret it when we have a hangover - it's easy to fall into the habit of unhealthy drinking.

How drinking too much affects your health

Drinking too much can lead to serious health consequences - both mental and physical.

Jennifer Walters, Director of Communications at the National Institute for Health and Care Research (NIHR), and former spokesperson for the UK charity Drinkaware says: "In the short term, alcohol can affect your sleep and your weight, and impair your judgement. Alcohol is the second biggest health hazard for developing cáncer - after fumar."

She explains that - in the long term - drinking above the recommended guidelines increases your chance of seven types of cancer, including mamario, hígado, y boca cancer. Other effects include raised control de la presión arterial, hepática grave, brain damage and mental health issues.

Stephen Buckley, Head of Information, Mind adds: "Many of us drink more than usual at Christmas. While for most it's not a huge issue, becoming dependent on alcohol can affect your salud mental. It may cause difficulty thinking clearly or problem solving, and trigger feelings of ansiedad."

Walters explains that drinking heavily and regularly is associated with symptoms of depresión, although it can be difficult to separate cause and effect.

"Reducing or stopping drinking can improve mood," she says. "To look after our mental health, reducing how much we drink is an important first step."

Cutting down your intake of alcohol isn't always easy, but there are steps you can take to reduce it.

Know your triggers

Understanding why you drink can help you manage your drinking. People, places, times and emotions - such as feeling sad or happy - can also be linked to drinking alcohol.

"Think about what your own personal triggers to drink alcohol are and how you can change your behaviour to fit your lifestyle," Walters advises. "It might help to talk to someone about it - a friend, your doctor, or anonymously with a trained professional over the phone.

"To succeed in reducing your drinking you may need to break associations. For example, if you tend to reach for a drink when you come home from work - or stop work if you're working from home - plan an alternative activity to try to break this link. You could go for a walk or read your favourite book instead."

Avoid 'all or nothing' thinking

If you've cut back on your drinking and you've been doing well, it's easy to feel you've blown it completely if you slip up. However, it’s important to avoid this 'all or nothing' thinking.

"Remember this is all about moderation to be kind to yourself and get back on track as soon as possible," says Walters. "Reducing your drinking is a marathon, not a sprint, so take it day by day. Focusing on one day at a time will help the journey feel more manageable."

Get support

Telling your friends and family about your goals over Christmas can help them understand why you may turn down drinks, or perhaps taking up new activities in place of drinking. Getting their support can also help you stick to your goals.

Walters says: "There are times when friends and family might not be as supportive as you'd like and they may not even realise it. If this is the case, remind yourself of your 'why' and that you alone are in control of your decisions."

"If you're worried about your own drinking or someone else's, it's more important than ever that you stay connected to people by phone or video calls to seek or offer support and strength by talking to someone," adds Walters.

You can do this anonymously in online groups, with trained advisors and counsellors or with friends or family. Organisations including Drinkaware, AA and the Alcohol Health Alliance offer advice, support and resources.

It can help to speak with your doctor if you think you have an issue with alcohol. They can provide advice on the best course of action for you.
