Temperature shock for human well-being

Don't know, but you get the inverse here in winter sometimes. Wrap up nice and warm for the outdoors and find within a minute or two of being indoors (heated shop for instance) you've broken out into a sweat.

An average temperature setting for feeling comfortale should be 24ºC + 40% air moisture.

Problem is people sets AC in summer at winter temperatures (18-21ºC) in winter they do the opposite (24-28ºC). WEIRD!!!!!

Right!

HVAC setting (army standards) winter: 68F=20C & Summer 78F=26C.

Somebody knows German cars Klimatizerung standards?

Air temperature shock isn't so bad due to it's low thermal mass. There are fatalities every summer here when people get hot and then dive into rivers or lakes and the thermal shock is too much for them..

Take a couple of aspirin and drink lots of orange juice. You'll be fine.

I don't agree that the mere changes in temperature will make one sick but it may reduce the resistance to infection.

Badly designed, maintained or operated HVAC units seems to be a bigger problem

I don't agree that the mere changes in temperature will make one sick

You are right Hendrik: changes in temp have nothing to do with getting sick (this is a secret, so: please don't tell my Mom!)

Talking of passenger ships, reminds of the days when POSH was written on the baggage.

Do any of the readers know why?

I'll give you a couple of days,its not that hard, but I bet someone from the UK knows first!!!

Lets see if there is anyone from other counties that knows it too!!

I bet its on Google somewhere.....don't cheat!!!

You don't need Google as long as you've watched Chitty-Chitty Bang Bang at some point in your life. I can still hear Lionel Jeffries singing Port Out Starboard Home.

(Have you seen the Blackle alternative to Goggle?)

Port Out Starboard Home. If you had a port side cabin going east on the way out and a starboard cabin returning west, you were on the southern (sunny) side of the ship.

No, it means you are NOT on the usually sunny (hot) side of the ship, in the days before AC.......it also costs more to have such a cabin, which is why such (rich) people were later called Posh.....without the full stops.

It was for the passage to and from India, from the UK, in the days of the British Raj....

By the way, Port is left, Starboard is right when looking in the forward direction!! maybe you got them mixed up.....

Got that backwards, you would be in the shade both ways. Being on the shady side of the ship was more comfortable and the ticket being more desirable was more costly. An easy way to keep it straight. Port, left, and red are all words that are shorter than starboard, right and green.

I believe it stands for port out starboard home.

For all who said Port Out Starboard Home, you are correct.

Out being India, Home being the UK.
