The Curious Habit of Dressing to Be Cold

One of the strangest things, in my observation of other people, is that they dress as if it was warm when it was cold. They dress in shorts and t-shirts to walk in the mountains in spring. That’s quite absurd, given how the mountains, in April tend to be cold. Others dress in shorts and a t-shirt to go running when it is barely above freezing and I find this behaviour absurd too.

Cycling and Suspected Heat Exhaustion

Over the last week I have cycled, and climbed over 3000m. Yesterday I climbed 1664 meters over an 89 kilometre ride. It was divided into the first climb, from the Léman towards La Cure, then a flat bit, ridden fast, before getting to the climb to Marchairuz and that is when I ran out of power. I wasn’t hungry, or thirsty. My legs were fatigued, after climbing up the Jura on Wednesday, Thursday and Saturday.

The Beauty of Flowing Air

People think that to be comfortable on a hot day you need to rush to an air conditioned room or building but that idea is wrong. When I worked on one building, for three years, I called it “air conditioned hell” for a simple reason. For the body to cool it needs air flow to help evaporate water. When there is no air flow it feels stuffy, and we interpret this as being too hot.

The Morning Run

Usually I like to go out in the afternoon because that was often when I felt the need for a mental break. This morning, and yesterday, or a day or two I went out in the morning. Part of the reason for this is that summer temperatures are arriving. We are getting back to 30°c or more, and running in that temperature is not as pleasant. Noise and Comfort There was little noise pollution yesterday so I opened the balcony door in the morning, and a velux and I had a nice cooling draft in my apartment.

Spring is Coming

Recently it has been feeling warmer as spring is making an appearance. I noticed that buds and leaves are getting ready. Orchids are flowering and trees are ready. I also noticed that there is quite a bit of pollen in the air and it’s warmer. Warm enough to start thinking about cycling. I went for a bike yesterday and I felt warm enough for almost the entire bike ride. This feels good.

The Water Bottle Paradox

This weekend when I hiked to Valangin I thought that I would found a water fountain along the way, so I took just 600ml of water. A few weeks ago when I went to Charmey I took the same amount of water because I didn’t want too much weight for the Via Ferrata. The result is that I have run out of water twice recently. The paradox is that this isn’t because I lack water bottles.

Experimenting with Air Conditioning

I live in a Minergie, which, in theory, means that I never need to worry about climatisation because the building keeps itself warm in winter and cold in summer. In practice the features that make a flat fantastic winter make it awful in summer. Good in Winter Large windows, in winter allow heat radiation in, so you use the sun to heat your apartment. From Spring until Autumn it has the opposite feature.

Keeping Cool in a Heat Wave

We are currently in a heat wave. During heatwaves my velux heat up in the afternoon sun and radiate heat both into the apartment during the day but also at night after the sun has set. I have found that during a heat waves it is wise to close the blinds and close the windows as soon as it is hotter outside than inside. When it is hotter outside than inside closing windows keeps the apartment slightly cooler, but not much cooler.

On Summer Heat

For as long as I remember I have enjoyed summer heat. For a long time I lived in a house that was like a cave in summer. It would be 30°c outdoors but 21 to 25°c indoors. It felt like stepping into a cave when I got home. For a summer or two I lived in a apartment on the 5th floor in Meyrin and during the 2003 summer heat wave I would open the windows on both sides of the building and get a nice draft.

Watching the Weather Again

For five years it was sunny almost every day in Switzerland. It was sunny so often that the water tables declined and village fountains dried up, as did fields. Clouds of dust could be seen rising when tractors worked the fields. It’s because of this excellent weather, for years in a row, that I stopped looking at weather apps. Now, weather is interesting again. Two or three weeks ago Geneva flooded.
