“Activity is one side of the exercise coin. The other is sleeping.
Most of us know that we turn into grumpy old men if we don’t get sufficient sleep. There is no need to deny yourself sleep just because you’ll be sleeping on your own. So instead of staying up late watching TV, go to bed and get a good night’s sleep.
Not only will a lack of sleep make you grumpy, there’s plenty of evidence (which you can read online if you need to convince yourself – ask our friend Google about sleep deprivation) that not getting enough sleep leads to things like:
- Reduced alertness
- Shortened attention span
- Slower than normal reaction time
- Poor judgement
- Reduced awareness of the environment and situation
- Reduced decision-making skills
- Poor memory
- Reduced concentration
- Increased likelihood of mentally ‘stalling’ or fixating on one thought
- Increased likelihood of moodiness and bad temper
- Reduced work efficiency
- Loss of motivation
- Errors of omission – making a mistake by forgetting to do something
- Errors of commission – making a mistake by doing something, but choosing the wrong option
- Micro-sleep – brief periods of involuntary sleeping that range from a few seconds to a few minutes in duration.”
