Let’s not forget that low mood, depression and even dementia can be linked to tiredness so getting enough sleep is every bit as important as exercise.
Scientists have identified a self cleaning function that the brain uses to get rid of waste. It is called the ‘glymphatic system’ and it goes into overdrive while we sleep. Failure to remove brain waste may be linked to a higher risk of developing dementia. So, in addition to our daily exercise regime, sufficient sleep keeps us sharp, creative, attentive and able to process information quickly. Aim for seven to eight hours per night.
