people talk about grief as an emotion, but for many, the first thing they notice is physical. the bone-deep tiredness. waking at 3am. not being able to eat, or not being able to stop. a heaviness in the chest that makes it hard to breathe. if your body feels different since they died, there are good reasons for it.
why does grief feel physical?
the death of someone close is one of the most stressful things a person can go through. the body responds to stress by releasing hormones like cortisol and adrenaline, raising heart rate and keeping you alert. in short bursts, this helps us cope. in grief, it can stay switched on for weeks or months.
that ongoing stress can affect sleep, digestion, appetite, energy and even the immune system. it's why grief can leave you exhausted even when you've hardly done anything, and why you might catch every cold going.
"a broken heart" is not only a metaphor
in rare cases, intense emotional stress can trigger a temporary weakening of the heart muscle known as takotsubo cardiomyopathy, sometimes called broken heart syndrome. it is uncommon and usually recovers, but it is a reminder that the body takes grief seriously.
if you have chest pain, breathlessness or feel faint, don't assume it is 'just grief'. get it checked straight away.
grief is not only in your head. it is in your sleep, your appetite and your chest.
sleep, appetite and energy
many bereaved people find their sleep changes completely. you may lie awake, wake early, or have vivid dreams about the person who died. some people sleep much more than usual, as if the body is trying to shut down for a while. both can leave you exhausted.
appetite often changes too. some people can't face food at all, or find that everything tastes of nothing. others find themselves eating more, especially comfort foods, or eating without noticing. alcohol can feel like it helps in the moment, but it tends to make sleep and mood worse over time.
energy can be very unpredictable. one day you might manage a walk and a phone call; the next, a shower feels like too much. this isn't laziness or weakness. grief is physically and emotionally demanding, and the body needs more rest than usual while it carries it.
aches, illness and the immune system
headaches, back and neck pain, stomach problems and tight muscles are all common after a death. some people feel a physical ache in their chest or throat when they cry or remember. these sensations are real, and they are often linked to the long-running stress that grief can cause.
there's also evidence that grief can affect the immune system. studies of bereaved people, especially older adults, have found changes in immune function in the months after a loss. that may be one reason people often catch colds and infections more easily while they're grieving.
none of this means that something is wrong with you. but it is a good reason to keep an eye on your health, keep up with any medication or appointments you already have, and see a gp if something feels new, worrying or isn't getting better. grief is not a reason to put your own health on hold.
small ways to steady the body
grief can make looking after yourself feel pointless or impossible. it helps to think in very small steps: one glass of water, one nourishing thing, one short walk outside, one early night.
slow breathing, with a longer breath out than in, can help calm the body's stress response for a moment. so can gentle movement, warmth, and being near someone you trust.
when to see a doctor
grief is not an illness, but it can make existing health problems harder to manage and bring on new ones. it's worth booking an appointment with a gp if you're struggling to sleep for weeks at a time, have lost or gained a lot of weight, feel exhausted all the time, or notice new pains or symptoms that worry you.
it's also important to keep up with any treatment you already have. grief can make it easy to forget medication, miss appointments or stop looking after long-term conditions. a friend or family member may be able to help you keep track for a while.
seek urgent help if you have chest pain, difficulty breathing, feel faint, or have thoughts of harming yourself. these are not things to wait out.
many gps see bereaved people often and understand how much grief can affect the body. telling them about your loss can help them make sense of what you're experiencing and point you towards support, whether that's for your physical health, your sleep, or your mood.
