In the highest part of the atmosphere called the thermosphere gas temperatures are high?

In the thermosphere, temperatures can soar to thousands of degrees Celsius due to the absorption of high-energy solar radiation by sparse gas molecules. However, despite these high temperatures, the thermosphere would not feel hot to a human, as the density of gas is extremely low, meaning there are not enough molecules to transfer heat effectively. This layer of the atmosphere also plays a crucial role in the ionization of gases, leading to phenomena such as the auroras.
