5 Ways To Reignite Your Mental Stamina

Trying to work when exhausted, demotivated or stressed is a common problem and it comes with a huge cost.

5 Ways To Reignite Your Mental Stamina

Presenteeism impacts productivity, performance, wellbeing and safety, and costs the Australian economy over $44bn each year. Finding ways to reignite your mental stamina include:

Get enough sleep – It is estimated over 30% of the population struggle with sleep. Operating in a 24/7 society means we either get too little, or too fragmented sleep, resulting in daytime sleepiness, loss of concentration, slower speed of processing and we make more mistakes. Scheduling a regular bedtime routine, keeping the bedroom cool, dark and quiet and turning off all technology 60-90 minutes before bedtime can help.

Give your brain a break – The optimum time for focused work is around 45 mins. Taking a 15-20 minute brain break refreshes and re-energises the brain to be ready for the next chunk of focused thought.

Take a technology detox – On average we are on-line for 10.5 hours each day. This consumes a great deal of mental energy. Switching off even for a short period when in meetings or during face-to-face conversations helps to restore mental energy. Recent research has shown how putting the mobile phone out of sight reduces stress levels and contributes to better attention.

Refuel regularly – The brain consumes over 20% of all the energy we take in. Studies have shown how our choice of food impacts energy, mood, memory and cognition. Taking a proper lunch break, looking for healthier food options based on the Mediterranean style of diet, along with drinking plenty of water to keep hydrated keeps our mental energy flowing.

While caffeine is often used as a kick-starter to keep us alert, it can also make us feel more tired because it leads to more adrenaline being released, reduces insulin sensitivity and impacts sleep quality. Keeping your caffeine intake to 300 mg (3-4 cups of coffee) and consuming it in the first half of the day helps to conserve mental energy and better sleep.

Fit in some exercise – Paradoxically exercise helps to reduce fatigue. The increase in blood flow with the additional oxygen and nutrients primes the brain for higher performance. That’s why exercising early in the morning is ideal. The gold standard for aerobic exercise (anything that gets your heart rate up) is 150 minutes a week, but all physical activity counts. The greatest risk to mental fatigue is sitting too long, so get up to stretch or walk for a few minutes every hour, try a variable height desk, hold standing or walking meetings and look for new opportunities to move more across the day.

Fatigue is a cognitive menace. Placing a higher value on those lifestyle choices and workplace practices shown to boost mental energy is the best way to fight fatigue.
