Cooling tips

[big-all]

2 or 3 litre bottle off flat pop /diluting juice half full placed in a freezer lay flat overnight or at least 4 hours
another 1 or two full bottles in the fridge
in the morning fill the frozen bottle from the fridge bottle
transport in a coolbox together or lay on a seat or other surface together and cover with anything cloth or fabric to keep cool
keep decanting into the frozen bottle then you will then have ice cold to cold drinks all day

if you cant lay the frozen bottle exactly flat just make sure the neck end is upper most

...to make a DIY air cooler, all you need to do is blow air over something cold. There are many YouTube videos showing different ways to create your own air conditioning surrogate, but the most basic is a bowl of ice water in front of a fan. Just be very careful with water and electricity.

Another popular technique is to use an old coolbox or polystyrene tub with a fan. Cut a hole in the top of the box big enough for a fan to blow into it, then cut an exhaust hole for the air to leave. Fill the box with ice packs or bottles of frozen water and let the fan blow straight down into the box over the bottles to pump colder air into the room.

in hot countries women wear a Black Burka - may be that works ?

I open the loft hatch. The hottest air rises through the house by convection, and escapes through the eaves. You can feel the strong airflow.

Opening a downstairs door or window on the coolest side of the house speeds up the effect. But once the sun is up, and the temperature outside the house is higher than inside, shut the doors and windows and close curtains and blinds.

You don't need to shut the loft hatch because the convection currents are driven by the temperature difference.

It doesn't even need to be cold, wet items. Hang several wet towels, in front of a fan, blowing across them. The passing warm air, will be cooled down several degrees, by evaporation from the towels. Just keep the towels damp. The downside of all such methods is, it will increase the humidity in the room, so best have the cooled air blowing on you, but have a door open.

You can buy commercial versions of the water evaporation air cooler, but why bother?

Let us know how you get on, won't you.

Ice cubes. In my case the thinnest point of my body (which is not an extremity) is my wrists. Get to the pub and rub an ice cube on your wrists. You will leave a puddle, but your core temperature will drop. I bunked off work early today, in part because my local has aircon.

No ice cubes were harmed though

Similar idea - a quick cool-down method I use when out, is simply to run cold water over my hands.

Run the cold tap over your wrists, good for hangovers too.

Feet - both have lots of blood vessels in them, so the effect of cooling the core temperature down, is almost immediate. I used to, back in my youth, do lots of hiking, and if I saw a stream, in hot weather....

I've had one on all day...it doesn't help

I can see how that works at night when it is cool outside.

But once the sun is up, and the temperature outside the house is higher than inside, shut the doors and windows and close curtains and blinds.

You don't need to shut the loft hatch because the convection currents are driven by the temperature difference.

But I still can't get my head around the logic of doing it during the day. On a hot sunny day, a typical loft with joist insulation is like a furnace due to the radiant heat from the tiles. And anyway the "warm" air from the house is still cooler than the air outside. So, you will only be replacing warm air with even warmer air from outside.

If the loft is insulated this is a bad idea, the warm air will act as micro temperature inversion, unless the loft space is extremely well ventilated.
