Having a thousand things on your mind, thinking about what's still left to do, planning tomorrow before today is even over. Even when everything around you looks calm, your mind can keep running at full speed. This constant mental activity has a name: mental load. It stays invisible, yet it is very real, and over time it can wear down your balance and your energy.
What is mental load?
A concept defined in the 1980s
Sociologist Monique Haicault put forward the first definition in 1984: mental load is the fact of thinking about one area of life while being physically present in another. In her book La gestion ordinaire de la vie en deux, she describes the double day faced by women, caught between domestic work and rising professional demands.
Dictionaries have since picked up the term, describing it as a psychological weight, carried more often by women, linked to managing household and childcare tasks, and leading to physical and above all mental fatigue.
Researcher Nicole Brais describes it as a task of managing, organising and planning that is intangible, unavoidable and constant. Three words that explain why this load stays invisible: it has no start, no finish, and leaves no measurable trace.
Mental load, stress and burnout: what sets them apart
The three ideas overlap without being the same thing. Mental load refers to the mental resources needed to hold everything together: anticipating, organising, remembering, deciding. Stress is the body's physiological response to a situation it perceives as demanding. Burnout describes a broader state, physical, mental and emotional, that sets in after prolonged exposure to this tension.
A high mental load can feed stress and contribute to burnout, without being its only cause. It is possible to carry a heavy load for years without burning out, especially when there is time to recover, support from others, and enough resources day to day.
Domestic, professional, emotional: the three faces of mental load
We tend to talk about mental load in the singular, when the plural would often be more accurate. Every area of life produces its own load, and it is the sum of all of them that eventually overwhelms.
Domestic and family load covers everything that needs to be anticipated and organised to keep daily life running: planning meals, thinking ahead for groceries, managing children's activities, keeping track of appointments, remembering birthdays or upcoming enrolments. At work, the mind stays just as busy: meeting deadlines, hitting targets, making decisions, coordinating with colleagues, answering messages, right through to the kind of hyperconnection that can stretch the working day well past the moment the laptop closes. Emotional load, the most discreet of the three, is the emotional availability given to others: noticing when a child is struggling, easing tension in a relationship, supporting an ageing parent.
Mental load at work, a prevention issue
Long associated with running a household and family life, mental load is just as present in working life. It covers everything the mind has to handle to manage a role, make decisions, organise itself and deal with the unexpected. At work, it tends to rise when tasks pile up, deadlines tighten, files become more complex or interruptions multiply. It can also increase when expectations are unclear, when there is little freedom to organise one's own time, or when several digital tools have to be juggled alongside the actual job.
There is almost always a gap between the work as described in a job description and the work as it is actually carried out. It is in that gap that the load builds up, often without appearing in any indicator.
Two questionnaires are commonly used as reference points at work: the Karasek model, which measures the tension between job demands and the latitude given to the employee, and the Siegrist model, which looks at the imbalance between effort and reward. These self-assessments are informative rather than diagnostic, and mostly help put a situation into words.
In France, the Labour Code sets out a clear obligation for employers: under Article L. 4121-1, employers must take all necessary steps to protect the physical and mental health of their staff. Reviewing workload, together with staff representatives, is generally the first step.
Why women carry more of it
INSEE figures for France in 2010 show the scale of the gap: women carry out 64% of domestic tasks and 71% of parenting tasks. This imbalance is not only about who does the tasks, but who organises them. It is usually women who keep track of what needs to be done, when, and by whom.
Sharing out tasks is not enough to share the load itself. As long as one person keeps the whole list in their head, they keep carrying the most tiring part of the work. Real sharing starts when each person takes full ownership of an area, from spotting the need to seeing it through.
Outsourcing does not solve the issue either. Hiring help for cleaning or childcare still means choosing the right person, organising their schedule, and checking that everything runs smoothly. The load of doing the task goes down, the load of managing it stays. That management is also often passed on to other women, which shifts the imbalance rather than closing it.
Another effect that is rarely anticipated: the person who organises everything ends up becoming the household's default decision-maker, and is sometimes resented for a role she never chose. Family sociologists describe this pattern, and it explains part of the emotional fatigue linked to mental load.
The signs of an overloaded mind
The signals the body sends
Fatigue is usually the first sign, with one particularity: a single night's sleep does not always clear it. It is possible to wake up as tired as when you fell asleep, even after several hours of rest. Broken nights and trouble falling asleep tend to follow, once the mind keeps turning over everything it will have to handle the next day.
Other signals build up gradually: tension in the neck and shoulders, recurring headaches, digestive discomfort, irritability that rises faster than before. Concentration drops, short-term memory becomes less reliable, and even simple decisions demand a disproportionate effort. Many people describe a feeling of being overwhelmed and a vague guilt about never doing enough.
A single one of these signs is not enough to draw a conclusion. It is their repetition and build-up over several weeks that deserves attention. When they start weighing on daily life, do not hesitate to talk to a health professional or, in a work context, to occupational health services.
What happens when the load never eases
Faced with a demand, the body mobilises its resources: cortisol rises, attention sharpens, the body goes on alert. This mechanism is useful as long as it stays temporary. The imbalance appears when the alert never switches off, because there is always something left to anticipate.
The adrenal glands, which produce this cortisol, end up working continuously. The response eventually weakens: the body needs more energy for a smaller result. Sleep deteriorates, digestion becomes irregular, natural defences wear thin and seasonal discomforts keep coming back. It is this depleted ground that needs support, not just the surface feeling of tiredness.
Easing mental load: what actually helps day to day
Write tasks down. A written list, on paper or in a shared app, takes the constant work of remembering off the brain. The effect on that overwhelmed feeling shows within the first few days.
Take on whole areas, not single tasks. Taking full charge of all medical appointments, or the whole of the week's grocery shopping, also transfers the load of thinking about it. Handing over a single isolated task leaves that load in place.
Sort out what actually matters. For every recurring task, one question is enough: what happens if I skip it this week? Many tasks survive out of habit rather than necessity.
Protect time with no demands at all. Ten minutes of walking, five minutes of slow breathing (five seconds in, five seconds out, three times a day), a break without a phone. These are the only moments when the nervous system truly comes back down.
Protect sleep. Seven to eight hours a night, screens off one to two hours before bed, a cool, dark room. Sleep is the first thing mental load affects, and the first thing to restore.
These levers have a limit worth naming. Treating this purely as a matter of personal organisation reduces to an individual problem something that is also about how work is organised and how roles are shared. A longer leave for the second parent, shorter working days, or a discussion about sharing roles as soon as a child arrives, all carry more weight than a to-do list app.
How Buds support mental clarity
During periods of stress and overwork, the body can need support to get through these moments and gradually find its balance again. This is where gemmotherapy can play a role.
Its principle is simple: it uses Buds, young plant tissues still in full development, which hold everything the plant needs for its future growth. They sit at the heart of gemmotherapy and form the raw material of our Bud concentrates.
At HerbalGem, Bud concentrates are formulated to support the body from within, and are taken orally.
Fig Bud, for thoughts that loop
Fig Bud (Ficus carica), harvested in spring from the tree's young shoots, supports nervous balance and is one of the most widely used Buds in gemmotherapy. Its action targets exactly what mental load produces: thoughts that keep circling, nervous tension, restlessness that makes it hard to settle. It also acts on the stomach and gut, often the first affected when tension settles in for the long run.
Take it as a course over 1 to 3 weeks: start with 5 drops a day in a glass of water, away from meals, then increase gradually to 15 drops a day if needed. After 3 weeks, take a week's break before starting again. For children, the rule is 1 drop per day for each year of age, up to age 15.
Lime Tree Bud, for nights that no longer restore
Lime Tree Bud (Tilia tomentosa), harvested just before the buds open, supports nervous balance, and sleep remains its main use. It suits people whose mind stays active at bedtime, with recurring thoughts that push sleep further away. It also suits children, with the dose adjusted to their age.
Adults follow the same pattern: 5 to 15 drops a day in a glass of water, over a 3-week course, ideally before bed. Our stress and sleep solutions combine several Buds to work on both fronts at once.
Blackcurrant and English Oak Buds, when exhaustion has settled in
When fatigue is already deep-seated and the load has lasted for months, support shifts towards the adrenal glands. Blackcurrant Bud (Ribes nigrum) is the most versatile adaptogenic Bud in gemmotherapy. It supports adrenal function, which regulates the body's response to prolonged demand, and accompanies periods when fatigue has taken hold.
English Oak Bud (Quercus robur) takes over for the longer term. It supports the same adrenal functions and accompanies the body through prolonged periods of overwork. Buds with hormonal action, such as Oak, are not suitable during pregnancy. Depending on whether fatigue or mental clarity is the main concern, our natural solutions for fatigue and our support for memory and concentration take over from there.
Two points to close on: a course is judged over 3 weeks, not 3 days, and it does not replace sleep or a fairer sharing of tasks. It is support while the rest gets reorganised.
