Holiday parties are usually associated with indulgent food, socialising and celebration. For many people in the UK and US, however, they also bring anxiety linked to bathroom use, according to new research.

A survey by UK bathroom retailer QS Supplies polled 1,000 adults across the two countries to examine how festive diets, social expectations and practical concerns affect bathroom habits during the holiday season.

Food and increased bathroom use

The findings show that festive eating habits often lead to more frequent bathroom visits. Overall, 69% of respondents said holiday foods increase bathroom use, with 26% saying “definitely” and 43% saying “maybe a little”.

Dairy heavy dishes and alcohol were identified as the main triggers. Toilet paper use also rises during this period, increasing from 4–5 rolls per week in the UK and from 3–4 rolls in the US. Christmas leads to the highest toilet paper use for 60% of Brits, compared with 28% of Americans.

Bathroom anxiety at social gatherings

The survey found that bathroom anxiety is widespread during holiday events. In total, 61% of Americans and 58% of Brits said they experience anxiety about using the toilet at gatherings.

More than half of respondents admitted to avoiding the bathroom altogether while socialising, with 56% of Americans and 53% of Brits saying they often hold it in at parties. The discomfort is linked to fears of awkward noises, smells, or judgement when using the bathroom in someone else’s home.

Stocking up and hosting expectations

Practical worries also play a role. Before the holidays, 58% of UK residents and 55% of US residents said they stock up on toilet paper. Three quarters of respondents believe that running out of toilet paper reflects badly on the host.

The survey also highlighted some lesser discussed habits. Around 16% of Americans and 13% of Brits reported frequently experiencing “ghost poops”, where they wipe but find nothing on the paper.

QS Supplies said the research was conducted to highlight everyday but rarely discussed issues surrounding bathroom use during the festive season. The company sells bathroom products and uses surveys to explore common household concerns.

The findings suggest that while holiday meals often include rich foods that affect digestion, social pressure discourages people from using the bathroom comfortably. As a result, many endure physical discomfort to avoid embarrassment.
