Today is the longest day!
It isn't really as every day is 24 hours, but in the Northern Hemisphere today is the day where we get the maximum amount of daylight! I was going to say sunshine, but here in North Devon it is a gloomy overcast sort of day!
However, we get natural infrared in nature.
When infrared rays touch a surface they will cause it to heat up, the
most common example of this is sitting in the sun. The suns infrared
rays will provide healthy warmth on the skin irrelevant of the outside
temperature, you may even be enjoying the sunshine whilst in the snow on
a skiing holiday.
A warm sunny wall is also the result of the suns
infrared rays this time heating the stonework which in turn radiates the
heat back.
Every object that is warmed will radiate some
electromagnetic heat radiation back, the intensity of the radiation
increases as the vibration of the atoms in the object increases.
