1. Pump up the pink noise
You’ve heard that white noise (like the light sound of a ceiling fan) is one small change you can make to catch more Zzzs .
But pink noise, in which lower frequency sounds are more powerful, like the rush of a waterfall or pounding rain, may boost your brain, according to a new study from Northwestern University and published in the journal Frontiers in Human Neuroscience.
The researchers found that when older adults listened to pink noise, their deep, slow wave sleep improved, and then they scored three times higher on a memory test the next day compared to after receiving a sham treatment.

2. Take a whiff
You already know that the smell of baking can send you straight back to mum’s kitchen, but it can also strengthen your brainpower at night.
After going to sleep, the researchers sent the rose odor back into the room for one group.
Those who were exposed to this scent during the night, during slow wave sleep, had a better recall of the day’s task compared to control groups.
The researchers say that the olfactory system activates prior memories in the hippocampus, making it easier to store new info.
All you need is a diffuser and your favorite scent and you’re ready to make memories.
