Mental load, unpaid work, and parental burnout: the research
These are the studies behind the conversation about mental load, unpaid work, and parental burnout. Each page summarises one paper accurately, links to the source, and explains where a shared household system fits and where it doesn’t.

Cognitive household labour
The work of noticing, planning, and remembering what a household needs is now a measurable category of labour. These studies map the size and shape of that work and who is doing most of it.
Allison Daminger’s 2019 study separated the physical work of running a household from the cognitive work behind it, and named the four phases that make up the invisible half.
A 2024 study by Aviv and colleagues found that mothers do more overall domestic labour than partners and that the cognitive labour split is especially gendered, with knock-on effects on depression, stress, burnout, and relationship functioning.
A 2024 University of Bath IPR analysis found mothers responsible for 79% of daily household coordination versus fathers’ 37%. The split flips slightly on episodic tasks, but with significant duplication.
A 2024 University of Bath study reported that mothers carry 71% of the planning, scheduling, and organising that keep a household running. Here is what the research found and why it matters.
The unpaid-work gap
National time-use data on the gap between what women and men spend on unpaid work in the UK.
The Office for National Statistics’ Autumn 2023 Time Use Survey found UK women spent 3 hours 37 minutes a day on unpaid work versus 2 hours 43 minutes for men, a 54-minute daily gap that adds up to over six hours a week.
Relationship fairness and satisfaction
How the perception of fairness, appreciation, and division of household work shapes relationship satisfaction.
Gordon and colleagues’ 2022 study found that feeling appreciated by a partner buffers some of the negative effects of unequal household labour on relationship satisfaction.
Newkirk, Perry-Jenkins and Sayer’s 2016 study examined how housework, childcare, and perceptions of fairness relate to relationship quality across couples with young children.
Hiekel and Ivanova’s 2023 study found that changes in relationship satisfaction across parenthood transitions were more closely tied to perceived fairness of the household labour division than to the actual task split, an effect found for women but not men.
Parental burnout
The measurement instrument, prevalence, cross-cultural variation, and factors associated with parental burnout.
Ren and colleagues’ 2024 systematic review in BMC Public Health identified factors associated with parental burnout across the individual and interpersonal levels of Ecological Systems Theory, including parental personality, mental health, the parent-child relationship, and marital satisfaction.
Roskam and colleagues’ 2021 study of 17,409 parents across 42 countries found parental burnout varies significantly by culture, with individualistic Western countries particularly affected.
Roskam, Brianda and Mikolajczak’s 2018 Parental Burnout Assessment defined parental burnout around four dimensions: exhaustion, emotional distancing, feeling fed up, and contrast with the previous parental self.
Mikolajczak and Roskam’s 2021 paper estimated that about 5% of parents worldwide experience parental burnout, with prevalence closer to 9% in individualistic Western countries.
