Practices

Put a hand just below your ribs and let it move. Most of us breathe up in the chest, and the settling effect comes from lower down, where the diaphragm can actually shift.

You can check this lying down with a book on your stomach. If the book rises, the breath is going where you want it. If only your shoulders move, it…

A child cannot watch their own breathing, so give them something to watch instead. Bubbles through a wand show the out breath as it happens: too hard and it bursts, too weak and nothing comes.

Smelling a flower and then blowing it out gives each half of the breath a picture. The bubble wand is better still, because it answers back straight…

There is no breath that calms everyone. The one that settles your friend may leave you worse, and that is information about your body rather than a failure in you.

Labels like calming or energising are a rough guide at best. What actually happens depends on how you usually breathe, what your body has been…

Start with a count of four in and four out, then drop the count. Once the rhythm is there your body will choose its own length: six and six, eight and eight, whatever settles you.

The count is scaffolding. Holding onto it too long turns the practice into something you can pass or fail, which is the opposite of the point.…

Four in, hold four, four out, hold four. The holds are the strong part of this one, and they stay optional every single time.

Some people find the pauses deeply settling. Others meet the edge of what they can tolerate there, especially at the bottom of the exhale. Both are…

Rather than pulling in a big breath, breathe gently and slightly less than you want to, then wait. The deep breath that arrives by itself does more than the one you force.

Keep the breathing light and unhurried, and after a while a mild hunger for air builds. Let it build a little. At some point the body takes a fuller…

Holding your breath for a moment makes the next one deeper, which sounds backwards until you know why. The urge to breathe is driven by carbon dioxide, not by a shortage of air.

Sensors in the brainstem watch the level of carbon dioxide in your blood, and a pause, especially after breathing out, lets it rise a little. The…

The three ordinary breaths between rounds are not a gap in the practice. They are where you find out what the practice did.

Come back to normal breathing and check the body, the thoughts, the mood, the energy. Do not analyse it, just register it. Going round after round…

To find the soft ocean sounding breath, breathe out through your mouth as if fogging up a mirror. Then keep that same slight narrowing at the throat with your mouth closed, and let the sound get quieter and quieter.

Starting with the mirror gives you something to do instead of an anatomy lesson about a part of the throat you cannot see. Once the mouth closes, the…

Close your right nostril with your thumb and breathe in through the left. Swap fingers at the top, breathe out through the right, in through the right, then out through the left. That is one round.

The fiddliness is not a flaw in the design. Keeping track of which nostril and which stage takes up just enough of your mind that there is little…

Most claims about food and behaviour rest on weak studies. The ones worth taking seriously give each person both the real thing and a dummy at different times, with nobody knowing which is which, so that hope and expectation cannot do the work.

The food colouring trials are the standard example. Around 150 children each received drinks containing a preservative plus one of two dye mixes, or…

The same brand of sweets is often made with plant based colours in one country and artificial ones in another. If a company can make it without the dyes elsewhere, the dyes are not essential to the food.

Nine artificial colours are approved in the US, and the volume approved for use rose roughly fivefold between 1950 and 2012. One of them, Red No. 3,…

A real food allergy shows itself on the body: a rash, a swollen or inflamed throat, something you can see. Behaviour on its own does not identify one, although behaviour often improves once a genuine allergy is dealt with.

One child's attention and mood went back to her usual level once berries came out of her diet, and what made that findable was the rash and the sore…

The studies linking pesticide levels to ADHD are tangled up with income, since families least able to buy organic differ in plenty of other ways too. If organic food is affordable for you, fine. If it is not, you are not failing your child.

In one study of 1,140 children, 94% had detectable pesticide in their urine, and ADHD was about twice as common among those with higher…

Most eating advice quietly assumes a budget. Fresh food is expensive and does not keep, so a household relying on food assistance ends up buying what lasts, and what lasts comes in tins and packets.

If money is the constraint, say it out loud rather than nodding along and then failing quietly at home. The advice can be rebuilt around what is…

A second study, this time of 44 products, found only about half were authentic. Roughly six in ten were mislabelled, three in ten contained a substituted ingredient, and one in five held contaminants or fillers.

One study of this kind is a story about some bad batches. Two independent studies finding the same thing is a description of how the market works.…

Several herbal products change how fast the liver processes medication, which can leave a prescribed drug either weaker or stronger without a single change to the dose.

This is often why a supplement looks like it caused a relapse or a sudden run of side effects. Nothing about the prescription changed, so the pattern…

Two to be careful with in particular. Yohimbe reliably ramps anxiety up, so much so that it has been used in research to bring panic on, and kava is a sedative that stacks with alcohol and with sedating medication and has damaged livers at higher doses.

Kava has been restricted or banned in several countries over liver harm, which tells you how seriously that risk is taken. Yohimbe is a poor choice…

You cannot patent a plant, so there is little commercial reason to fund expensive trials of one. When you read that a herb has no evidence, that often means nobody paid to look rather than that somebody looked and found nothing.

Both halves of that need saying. No evidence is not proof of no effect, and it is also not permission to assume one. It leaves you with an open…

Herbal products are rarely covered by insurance and they add up quickly. That cost belongs in the decision, particularly when you cannot be sure the capsule holds what it says.

Money spent here is money not spent elsewhere, and often the alternative is a treatment that is covered and has been tested. Nobody is telling you…
