Detox teas & cleanses don't reset your body

Every January the same promise returns in new packaging: a tea, a juice, a seven-day cleanse that will flush out the festive damage and reset you to factory settings. It is a seductive idea. It is also one your body politely ignored long before the kettle boiled.

You already own a detox system

The word "detox" is doing enormous marketing work for a job your liver, kidneys, gut and lungs already perform continuously. They neutralise the by-products of normal living and clear them out without instruction or subscription. A sachet of senna does not assist that machinery; it just hurries the bowel. The "toxins" these products claim to remove are almost never named — because naming them would invite a question they can't answer.

"Feeling lighter" after a cleanse is usually water and an empty gut — not a body cleansed of anything.

What "feeling lighter" really is

The early whoosh on the scale is the familiar trio: less food in transit, lost water, and drained glycogen. Many detox teas lean on laxative or diuretic herbs, so you are dehydrating, not purifying. It comes back the moment you eat and drink normally — which is why the cycle is built to repeat, and to be repurchased.

When it stops being harmless

Beyond the wasted money, aggressive cleanses can upset the balance of salts your heart and muscles depend on, irritate the gut, and feed an all-or-nothing relationship with food where every "clean" week is paid for by a chaotic one. The body does not want a dramatic reset. It wants a few decent habits it can keep.

What to do instead

• Drink water because you're thirsty — your kidneys handle the rest.
• Eat enough fibre — vegetables, fruit, pulses, whole grains — to keep digestion moving daily.
• Go easy on alcohol and ultra-processed food; that's the real "support" your liver appreciates.
• Sleep. Recovery is the reset no tea can sell you.

There is no sachet for a healthy body, and that is good news — because it means the thing that works was never for sale. It was always just the ordinary, repeatable habits.
