Different energy levels

Treat it as a swap, not a verdict. Whoever has more in the tank right now covers a job or gives the other a breather, and next time you switch. Nobody is the lazy one or the tireless one; you're two people with different batteries.

Ask rather than tell. NHS guidance for parents suggests offering the swap as a question: "How would you feel if I did tea and you did bath this evening? Then we will both be able to relax sooner"³. It works just as well with no children in the picture: the dishes for the laundry, the cooking for the shopping.

Small breaks count too. The same guidance says even ten minutes with a cup of tea in peace can help³. Nobody needs a spa weekend; a quiet sit-down while the other one handles the chaos will do.

It also helps to talk about when each of you has most energy, and how each of you sleeps¹. Being different morning-or-evening types is linked with more conflict and less sex in some couples, yet being alike isn't linked with higher satisfaction¹, and the link may depend on how long you've been together². So don't panic about mismatched body clocks. Morning or evening type isn't the same as energy overall, either, so treat it as a clue, not an answer.

If snoring or another sleep problem is disturbing one of you, it can affect you both, and partners can be included when it's treated, so raise it with a doctor^1,4.

Look for changes from their usual self. Stress can show up as getting irritable, snappy or withdrawn⁵. Feeling tired and drained most of the time, and losing motivation, are listed signs of burnout⁶. Low energy, slower movement or speech, disturbed sleep, avoiding friends and neglecting hobbies are all listed among the signs of depression⁷. Tiredness and poor sleep can also feed irritability, so the signs tend to pile up together⁴.

You can't tell the cause from the outside, and you don't have to. Your job is to notice, not to diagnose. Burnout doesn't go away on its own and can get worse, so it's worth acting on rather than ignoring⁶. If you're worried about your partner, a doctor is a good place to start, and you can go along to the appointment together if that makes it easier. Tiredness that is unexplained, doesn't ease or worries you is worth raising with a doctor, who can look for a cause^9,4.

Then check in, kindly and without an audit: "You seem flat lately. How are you doing?" Be open about your own hard times too, because being honest about a tough patch helps you both feel supported⁵. Offer a short break or a kind word.

Try not to hide your own stress to protect your partner. In couples dealing with a medical condition, shielding each other from stress, even with good intentions, is linked with worse wellbeing and relationship quality for both people⁸.
