Dressing at five degrees
Short answer: Two layers and a jacket will do. Five degrees is the temperature at which most people put on too much and sweat on the way home.
What the body does at five degrees
When you walk, the body produces enough heat to stay warm in two layers. Stand still for more than ten minutes and you need a third. The clothing has to match the activity and not just the number.
The practical solution
A long sleeved layer in bamboo viscose against the skin, a thin jumper and a jacket you can unzip. The zip is what you regulate with. See bamboo long sleeved t-shirts for men.
What is often forgotten
Wrists and neck. Two narrow places where the blood runs close to the skin. Cover them and the whole body feels warmer. See bamboo clothing for men and bamboo socks for men.
Frequently asked questions
Do you need long underwear
At five degrees only if you stand still outdoors for a long time.
Why do you sweat at five degrees
Because the clothing was chosen for the coldest moment of the day.
Does a hat help
Yes, and it is easier to take off than a jumper. That makes it practical.
