SOMAWA Review: What 5,00,000+ Indians Have Experienced

The practice. Before the kettle, before the phone, before a word is spoken to anyone — two or three glasses of water, taken sitting, while the house is still. In older Indian households this was simply what one did on waking, and it was never hurried. The water stood ready from the night before, at room temperature. Nothing was eaten for a while afterwards. The day began with water, not with tea.

What the research says. You lose water all night through breathing and skin while replacing none of it. Randomised crossover trials from Ganio and colleagues in men, and Armstrong and colleagues in women, both published in 2011, found that a body-mass loss of only 1 to 1.6 per cent was enough to worsen mood, fatigue, vigilance and reported concentration in healthy young adults. Replacing that loss early is sensible. But we should be plain: the evidence supports the volume, not the hour.

Before you start. Room temperature rather than chilled, and sitting rather than standing — you are less likely to rush it. Two glasses is plenty to begin with; there is no merit in forcing down a litre. If you are on fluid restriction for kidney or heart reasons, or take diuretics, your doctor’s number is the one that matters, not ours.

The practice. Ghoont-ghoont — mouthful by mouthful. Elders would stop a child who had drained a glass in one breath after running in from play, and hand it back to be finished slowly, seated. Water was something you attended to, not something you dispatched. A glass took a minute or two. The instruction was rarely explained; it was simply the manner in which water was drunk in that house.

What the research says. Here the evidence is thin, and we would rather say so than dress it up. Plain water is absorbed quickly and almost completely whether you sip it or swallow it fast. What is better established is that a large, rapid volume briefly dilutes the plasma, suppresses vasopressin and sends more of it to the bladder — the beverage hydration index trial by Maughan and colleagues, published in 2016, measured retention differences of roughly this kind between drinks. No trial has shown that sipping improves a health outcome.

Before you start. Treat this as comfort and habit rather than physiology. Slower drinking means less bloating and fewer trips to the bathroom twenty minutes later, and that is reason enough to keep it. The one genuine caution runs the other way: very large volumes drunk very fast can outpace the kidneys and lower blood sodium dangerously. Slow remains the safer default.

The practice. The coastal Indian answer to a hot afternoon, sold from a cart with a curved blade and no packaging at all. A tender green coconut, opened in front of you, finished within the minute. It was what you gave someone who had walked a long way in the sun, or who had been unwell and could not keep much down. Cheap, everywhere, and far older than any bottle on a shelf.

What the research says. Coconut water carries roughly 250 mg of potassium per 100 ml, which is why it behaves like a rehydration drink at all. Crossover trials after exercise-induced dehydration — Saat and colleagues in 2002, Kalman and colleagues in 2012 — found it restored body mass about as well as a formulated sports drink. Ismail and colleagues, in 2007, found that adding sodium to it improved whole-body rehydration further, which tells you the honest thing: it is potassium-rich but sodium-light, and sweat mostly takes sodium.

Before you start. Fresh from the shell, not from a carton with sugar added. One tender coconut is a serving, not a jug. Because it is genuinely high in potassium, anyone with chronic kidney disease, or taking potassium-sparing diuretics or ACE inhibitors, should ask their doctor first. This is the one item on the list where more is not simply harmless.

The practice. A thumb of fresh ginger, scraped and crushed, dropped into water just off the boil, left to stand a few minutes and drunk warm. In most Indian kitchens this appeared after a heavy meal, or on the night of a wedding when everyone had eaten more than they meant to. No sugar, no milk, no ceremony. Ginger and hot water, and a little patience while it steeps.

What the research says. Ginger’s gingerols and shogaols are the compounds studied, and the mechanism is motility rather than magic. In a randomised, double-blind crossover study, Hu and colleagues, writing in the World Journal of Gastroenterology in 2011, gave 1.2 g of ginger to patients with functional dyspepsia and measured a faster gastric half-emptying time by ultrasound — around 12 minutes against 16 on placebo. Notably, symptom scores did not improve. The stomach moved faster; how people felt did not measurably change.

A word of caution before you start. Ginger has been reported to reduce platelet aggregation, so if you take warfarin, aspirin or any blood thinner, raise it with your doctor before making it a daily habit. Keep to a small piece rather than a strong brew, and leave it alone if you have active reflux — warmth and pungency together can make heartburn worse.

The practice. Amla in winter, when the fruit is hard and sour enough to make you wince. Grated or juiced, a spoonful stirred into a glass of water, sometimes with a pinch of salt to make it bearable. Households in the north kept a season’s worth put by. Children were given it diluted and complained loudly; the adults drank it as it came, and considered the taste part of the point.

What the research says. Amla is among the densest food sources of vitamin C measured, reported across cultivars at roughly 190 to 720 mg per 100 g of fresh fruit — many times an orange. The vitamin C is not the whole story, though: a large share of the antioxidant activity seen in laboratory assays is attributed to its hydrolysable tannins — emblicanin A and B, corilagin, chebulagic acid and gallic acid. That work sits largely in extract and in vitro studies, not in clinical outcome trials in ordinary households.

Before you start. It is genuinely acidic, so if you are prone to acidity, gastritis or reflux, take it after food rather than on an empty stomach, and dilute it well. One small fruit or a teaspoon of juice is a serving. Amla has been reported to affect blood sugar and clotting, so mention it to your doctor if you take medication for either.
