Book a flu jab, if you’re eligible, and if you’re offered a Covid-19 booster, take it.

The NHS recommends adults should aim to be active every day with 150 minutes of moderate aerobic exercise each week, combined with strength exercise two or more times a week. If the gym’s not for you, download a fitness app, or check out online videos. Joe Wicks has lots of free workout videos on his YouTube channel for all abilities.

Research has found that the body has to work harder to maintain its core temperature (37 degrees Celsius) in winter, so when you go for a brisk walk, more calories are burned.

Aside from the weight-gain effects of comfort food eating, a calorific snack late before bed can disrupt sleeping patterns and keep you awake as your body has to work hard to digest it.

While we are more likely to consciously fill our glasses in warmer weather, in winter we tend not to be so thirsty and drink less. Water is essential for hydration, aiding digestion and flushing out toxins though - no matter the season! - so aim to drink eight glasses a day, along with warming drinks.

Studies show that in warm conditions, the brain uses more glucose to control the body’s temperature, but when it’s colder, it directs this energy more towards recall and concentration, meaning we can carry out more complex tasks. Could there be a better reason to break up a working day with a brisk lunchtime walk or a jog?

It can be tempting to hibernate in the winter months, but sleep experts agree that sleeping too much can disrupt your regular sleep pattern, so get up at pretty much the same time every day of the week.

Doing something you really enjoy which completely absorbs you - such as crafting, writing or baking – produces the feel-good hormone dopamine. This is further underpinned by having something tangible to show for your efforts, so don’t hold back!

The cold, dark months can affect our mood and feelings of satisfaction. A lot of research shows that mindfully connecting with something you are genuinely grateful for teaches an appreciation for what you have (even if it’s as simple as a hot shower). That in turn nurtures feelings of contentment.

We all need human connection - but in the winter, there may not be opportunities to get out and about so much. Aim to actually chat to a couple of people every day at least – don’t text, WhatsApp or email - especially if you live alone.
