Fridge Socks

The surface of the Sun is 5500°C and i had the misfortune to spend the day in Central London today where the temperature was just a tad under that.
Thankfully the heatwave is due to break this weekend but we still have to make it through the sweaty armpits and sleepless nights to get there but the Red Cross have offered some helpful hints to stay cool, and one of them is wear socks.
People tend to put socks on to keep them warm but the Red Cross say that to keep cool at night during very hot weather, put a pair of socks in the fridge during the day and slip them on your feet before getting into bed.
There is some science behind it apparently because research has shown that putting your feet in cold water is a way of reducing your core temperature so cooling your feet is a good way of cooling your whole body.
I normally put my pillow case in the fridge for an hour before going to bed which gives you a 15 minute window to drop off before it warms up but after a yoghurt related incident i am very careful about it.  
Apart from the new twist of footwear, the Red Cross does have other tips for how to keep cool at night in a heatwave such as sleep on the lowest level of your home due to the heat rising, wear as few clothes as possible and also turn off electrical devices, which can generate heat.
They also say to avoid alcohol and caffeine in the evening, drink plenty of water to stay hydrated and take a lukewarm or cool shower to bring down your body temperature before going to bed although they don't explain if you should wear your socks in the shower cubicle.
Anyway, might be worth a try and you never know, if you are not careful then your feet may smell of Blueberry Yoghurt by the morning.
