The longest day!

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.
