Foods to Avoid. When youâre feeling a bit wired, avoid foods containing caffeine, alcohol, sugars, and processed ingredients. Caffeine is a stimulant that can produce a jittery feeling that might amp up your anxiety.
The Ice Ages began 2.4 million years ago and lasted until 11,500 years ago. During this time, the earthâs climate repeatedly changed between very cold periods, during which glaciers covered large parts of the world (see map below), and very warm periods during which many of the glaciers melted.
Glacials, on the other hand, refer to colder phases within an ice age that separate interglacials. Thus, the end of the last glacial period is not the end of the last ice age. The end of the last glacial period was about 11,700 years ago, while the end of the last ice age has not yet come. Over the past few million years the glacial-interglacial cycle has been paced by periodic variations in the Earth's orbit via Milankovitch cycles which are thus the cause of ice ages.
