Distraction isn’t all bad.
If we get distracted at work, it’s not great for productivity, but distraction has a positive side. If we were always so focused that we never got distracted, we’d miss potential changes, such as threats, in our environment. Imagine if you were concentrating so hard on a book that you didn’t hear a fire alarm going off. Distraction is vital for survival.

Silence is best.
Of course, there are plenty of times when you do need to concentrate and noise becomes a problem. For example, we’ve found that people do worse on tasks such as mental arithmetic when there’s background noise to disturb them.

Staying warm is a balance…
… between heat produced and heat lost. When we get cold, we often shiver because shivering generates heat. At the same time, blood flow is diverted away from the extremities, like the fingers and toes, to the torso. This helps protect vital organs, like the heart and lungs, and reduce heat loss to the surroundings.

Some people feel the cold more than others…
… even in the same environment. This is to do with size, fat and metabolism. Smaller people with less body fat lose more heat to their surroundings than bigger people with more fat. Bigger people may have more muscle mass, and are therefore able to produce more heat.
