Activity diaries can be used for many reasons, it could be because you’d like to work out how to use your time more efficiently, or where you can carve out time in your day for something new. We all want more hours in the day, but sometimes we just need to use the time we have, better. Being able to see how much time certain tasks actually take and where the gaps in our day are, can help us organise our time in a different way and demonstrate where we might be able to free up more time. Activity diaries can also be helpful for people with chronic illness, low energy levels, fatigue and sleeping disorders. Keeping a record of daily activities and energy levels throughout the day, can help highlight which activities tire us out the most, identify where we need to put in rest breaks and give us insight into how best to organise our time and use limited/restricted energy. For example spreading tasks out over the week rather than doing it all in one day. We can also look for a correlation between our daily activities and sleeping patterns. Sleep diaries help to give us insight into our sleeping patterns and highlight problem areas, once we are aware of specific patterns we are able to look for solutions. Both activity diaries and sleep diaries are very useful tools for doctors and specialists when they are looking into possible causes and treatments for sleeping disorders or fatigue.
