So at work today, the discussion of household heating and gas/electricity bills came up (entering winter Down Under), and I commented that we have our central heating set to 14 Celsius (approx 57 Freedoms) overnight, and off during the day/evening. We find that 14 is quite comfortable under a fluffy doona/duvet. I was warmly mocked (well natured), and informed that something closer to 24C (75F) is appropriate, day and night.
Surely not… right?
That’s not how colds work. Cold weather can reduce the immune system, but it doesn’t cause colds. You still need to be exposed to a virus to catch a cold. Also, it’s not like colder weather guarantees your body can’t fight off a cold.
It’s much easier (and cheaper) to heat a small space (a person wearing a sweater) versus heating an entire room.
Tell that to my body. From my own personal experience when the temperature drops below 23C I get a cold, simple as that and temperature has been the only fluctuating variable. So while the cold may not be the direct cause it’s a big enough influence for me that I’d rather not take my chances.
