Ever wished there were more hours in a day? Need to restore your energy levels
to catch up on all those things that need to be done? Two cups of strong coffee
is all it takes to make that difference.
Our natural body clock works on a 24-hour cycle and energy and alertness
levels rise and fall during that period according to the amount of sleep we have had
or failed to have.
Scientific studies have shown that caffeine can specifically help restore our
levels of energy and vitality back up to normal waking levels when we are tired
or deprived of sleep.
This is good news for all of us, and particularly important when tiredness is
a problem in the workplace. Such tiredness is common amongst those working
different time shifts or overtime, but also for many people during the working day.
Caffeine can help in several ways:
- It can sharpen abilities that are affected when we are tired including reaction
time, attention span, alertness, reasoning and communication skills.
- Counter factors such as depression and boredom often associated with tiredness
and which impair performance
- Increase our tolerance to exercise and muscular activity so that we can
undertake physical work for longer periods.
The effects are also long lasting and research has shown that whilst drinking
coffee will take 15 minutes to achieve 75% of its maximum effects and one hour
to reach its maximum effect, the overall effect will last three to four hours.
So plan ahead - if you have an important meeting to attend later today - drink
a cup of coffee around half an hour before it starts and it will help to
maximise your alertness. Studies have shown that even when we think we are alert, only
about 10% of us are actually at peak alertness.
Used in a practical way, coffee can help us through when working late and
helps to ensure we continue working and performing at our normal rested levels.
