Christmas, Sugar & Eczema. Is There a Connection, and What Should Parents Know?

Christmas in Australia is loud, joyful, hot, and usually filled with treats.

Between end-of-year parties, festive desserts, and well-meaning relatives offering “just one more,” many parents notice the same thing each year: eczema seems to flare around Christmas.

So the question comes up again and again: Does sugar actually make eczema worse?

The relationship between sugar and eczema is complex. For some children, sugar may contribute to flare ups. For others, it may have little impact. Understanding the bigger picture helps parents make informed, guilt free choices.

What the Research Really Says

There’s no strong evidence showing that sugar universally causes eczema flare-ups in every child. Controlled studies haven’t consistently proven that sugar alone directly worsens eczema symptoms across the board.

Eczema is a chronic inflammatory skin condition influenced by genetics, skin barrier function and environmental triggers.

However, diets high in refined sugar are associated with increased inflammation in the body. Since eczema is an inflammatory condition, this can help explain why some children experience worse symptoms when sugar intake increases.

This does not mean sugar is a trigger for every child. Responses vary widely.

Why Some Children Are More Sensitive to Sugar

Parents’ observations aren’t imaginary, and they deserve to be taken seriously.

For some children, sugar may:

• Increase inflammation

• Disrupt gut balance

• Contribute to sleep disturbances

• Lead to energy spikes followed by overtiredness

And when sleep suffers, eczema often follows.

It’s not always the sugar itself, it’s what sugar sets off in the body.

Why Christmas Is the Perfect Storm

Even children who usually cope well can struggle at Christmas because multiple triggers stack up at once:

• Late nights and overstimulation

• Hot weather and sweating

• Missed or rushed skincare routines

• New foods, additives, and preservatives

• Different bedding, detergents, and clothing

• Excitement, stress, and big emotions

Sugar often gets the blame, but it’s usually just one piece of a much bigger puzzle.

A More Helpful Way to Think About Sugar

Instead of asking “Should we cut sugar completely?”
A better question is: “How can we reduce the impact?”

Here’s what tends to help most families:

1. Focus on Timing

Sugar later in the day can:

• Disrupt sleep

• Increase night-time itching

• Lead to more scratching during lighter sleep

Earlier treats are often better tolerated than late-night ones.

2. Aim for Balance, Not Restriction

Christmas isn’t the time for strict food rules.

Instead:

• Pair treats with proper meals

• Encourage water alongside sweet foods

• Keep regular meals going where possible

Less stress around food often equals calmer skin.

3. Protect Sleep at All Costs

Sleep is one of the strongest regulators of eczema.

Support it by:

• Keeping a familiar wind-down routine

• Dressing children in breathable, non-irritating sleepwear

• Avoiding overheating

• Maintaining scratch protection at night

Even when bedtimes shift, comfort still matters.

---

4. Stick With What You Know Works

Christmas isn’t the time to trial:

• New skincare products

• New detergents

• New fabrics for sleep

Familiar routines and textures help skin feel safe.

So… Is Sugar Linked to Eczema?

A fair, evidence-aligned answer is this:

Sugar isn’t a guaranteed eczema trigger for every child, but for some, especially during periods of heat, poor sleep, and routine disruption, high sugar intake can contribute to flare-ups.

What matters most isn’t perfection, it’s awareness.

A Gentle Reminder for Parents

If your child’s eczema worsens over Christmas, it doesn’t mean you’ve done anything wrong.

It usually means:

• Life got busy

• Routines changed

• Skin became overwhelmed

And that’s okay.

Christmas should be about connection, comfort, and joy, not constant eczema anxiety.

Supporting your child’s skin through the festive season is about balance, comfort, and kindness, not cutting out every sweet moment.
