It’s official: warm weather makes it hard to think straight
Warm weather makes it hard to think straight
In a recent experiment into the impact of warmth on decision-making, colleagues from the University of Houston and the University of Virginia found the following:
1. It requires more energy (glucose) for the body to cool itself down than to warm itself up, thus diverting glucose from the brain
2. Glucose is essential for our brains to work efficiently – this includes processes such as decision-making.
3. In simple cognitive tasks, people in hotter environments make more mistakes than those in cooler environments.
4. People in hotter environments tend to be more reluctant to make decisions
5. People in hotter environments tend to make more conservative decisions, perhaps intuitively not trusting their own decision-making
6. People in hotter environments may also find it more difficult to exert self-control
A review of the study is here.
What you can do if you work in the Tropics
If you find that motivation and decision-making is an issue, then have a look at Emotional Intelligence, our one day training programme that empowers participants by making them more aware of the factors that influence their emotions, motivation and decision-making.
