Interglacial periods are a part of ice ages. Even tells you right at the beginning of that article.
> Individual pulses of cold climate within an ice age are termed glacial periods (glacials, glaciations, glacial stages, stadials, stades, or colloquially, ice ages), and intermittent warm periods within an ice age are called interglacials or interstadials.
You can actually see the definition (albeit a little verbose) as the first sentence of that article:
> An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers.
On a technicality, you can get me for not mentioning the snow capped mountains part, I'd concede on that. That part is actually news to me. All the same, the earth is colder than it usually is. [1]
An interesting thing I like to bounce around in my head: Could we live in the interior of the Pangean super continent if we had to? Interesting stepping stone between Earth's current, very mild climate, and trying to live in a place like Venus. Definitely would have to live like mole people.

- jefftk 2y agoMmm, looks like you're right. Sorry!
- johnnyjeans 2y agoNo worries. It's not commonly known! For as important as it's become to talk about the climate, the brass tacks remain pretty esoteric.
- nine_k 2y ago> Could we live in the interior of the Pangean super continent We already avoid living in the interior of Australia, because living at temperatures of +50°C is just not very compatible with having body temperature slightly below +37°C. Same applies to the middle of Sahara desert. It's not impossible though, because the humidity is very low there, so, given a supply of water, you can cool by evaporation. At high humidity. you'd just die; such things happen during heat waves on the Indian subcontinent, for example.
- samatman 2y agoPeople certainly die during heat waves, on the Subcontinent and elsewhere. High heat at high humidity is dangerous to endure. However, there is no historical record of the wet bulb temperature outdoors exceeding human body temperature, anywhere, ever. So far. Which is what it would take for the human body to be unable to remove excess heat in any fashion.

- relaxing 2y ago> However, there is no historical record of the wet bulb temperature outdoors That’s not really saying much. The historical record is vanishingly small.
- gaadd33 2y agoThe current record of 36.6 seems like it would be close enough to cause major issues.
- tbrownaw 2y ago> Individual pulses of cold climate within an ice age are termed [...] ([...] or colloquially, ice ages), Looks like both sides are right in this case.
