The claim is circulating that antidepressants can cause overheating and dehydration. This is a genuine public health message, but it's not so simple: diuretics, beta blockers, ACE inhibitors, antipsychotics, and some antihistamines may also interact badly with hot weather.
https://www.nytimes.com/2024/06/15/well/live/heat-weather-medication-safety.html (excerpt in a reply)

There's even doubt about antidepressants having this effect. A recent paper in eClinicalMedicine looked at all the studies they could find and concluded that there wasn't evidence of antidepressants causing overheating in hot weather - though some other medicines do.

"Current evidence supports strong anticholinergics, non-selective beta-blockers, adrenaline, and anti-Parkinson’s agents impairing thermoregulation during heat stress ... physicians should interpret with caution conventional public health messaging related to the thermoregulatory effects of some drugs (e.g., antidepressants) during hot weather."

#30DayMapChallenge Day 25:

🥵🚶 How far can vulnerable citizens walk under heat stress conditions?

The map shows which areas are accessible from public transport stops in #Heidelberg on a hot sunny day for heat-sensitive people, e. g. the elderly and children.

The colored areas indicate the distance these people can walk before experiencing #HeatStress. The smaller the area, the higher the sun exposition.

This is part of the #HEAL project:

"We also find ongoing regional climate changes after net-zero CO2. Global temperature stabilisation doesn’t mean climate stabilisation. In fact, the climate system is out of equilibrium and it will take centuries for the system to find it’s new ‘steady’ state. "
From a Bluesky thread about a new paper on "overconfidence in overshoot" #Schleussner et al 2024

https://www.nature.com/articles/s41586-024-08020-9 #openaccess!

They also developed a heat-stress calculator. it lets you pick a city. Pick a level of heatstress , say, "high"=28°C #wetbulb ,
or 50 #heatwave days like in the 🖼️

And then you can swivel a lever as to how many days you want to let a hotspot in Vienna experience this #heatstress per year.

The result then is at which policy_for_overshoot your set threshold is exceeded. https://climate-risk-dashboard.climateanalytics.org/impacts/avoid

Based on the climatology 2011-2020. Which is unusually short for a science paper or app. But makes so much sense, seeing that the #ClimateCrisis didn't kick Vienna in the butt before 2015.
