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.
An ice age is a period of colder global temperatures that features recurring glacial expansion across the Earthâs surface. Capable of lasting hundreds of millions of years, these periods are interspersed with regular warmer interglacial intervals in which at least one major ice sheet is present.
