Daft advice

Drink a lot?

If you multiply that litre of water by the millions brushing their teeth twice a day, then it will add up to a significant saving of total water used if they don’t leave the tap running whilst brushing.

I found drawing the curtains on the sunniest side of the house did help (but appreciate it does darken the room somewhat). Not only that, but it helps to keep the strong sun off the soft furnishings and suite, helping to protect them from fading over time.

Drink lots of lots of water and flush out your electrolytes.
I know from personal experience as to just how dangerous this is.
You are better off with an electrolyte mixture .

Most houses have rooms facing in more than one direction. Pull the curtains in the rooms facing south, and those facing east in the morning and west in the afternoon, and sit in the room that doesn't have the sun beating in. Simples.

67 million people all saving a couple of litres a day awful lot of water.

Well the advice was to draw the curtains to keep the sun and heat out, it said nothing about sitting in the dark or being bored. Our south facing curtains have been drawn for almost a month but that doesn't stop us sitting by other windows or going outside when it's a bit cooler. The windows are opened in the evening, sometimes overnight, when it's cooler then closed again as temps go up.

Drink a lot?

Nothing wrong with that!
Back in 1976 I remember a panellist on Any Questions, when asked for his tip for saving water suggested “Brush your teeth with chilled white wine” !

We don’t have a water meter but I always switch off the taps when brushing, or washing my hair, as can hear my mum shouting ‘water meter’ water meter’!in my head 😂

I never run the tap while brushing my teeth.

The tip I remember from 1976 is Save water, bath with a friend!
