Remember what life was like before you had kids? Maybe it's a little fuzzy, but before the sleep-deprived juggling act that is parenting, you probably didn't forget things like where you parked your car, who that person was that you just ran into at the store, or that you also know her sister. The good news is you can boost your memory by working out your brain in your down time.
Get Enough Sleep
Before you freak out at the impossibility of this suggestion, remember how important sleep can be. Harvard Medical School reports that "consolidated sleep throughout a whole night is optimal for learning and memory." Not everyone needs the same amount of sleep, but you'll know if you are sleep deprived. If you are, start making an effort to carve out more time to sleep through the night.
I use a fitness tracking wristband that also tracks sleep to keep tabs on how long I've slept and how well. My kids are older now, but I still have the challenges of jet lag to deal with and sleep tracking can help me make sure I don't go too far with burning the candle at both ends.
Simple games are a great way to exercise your memory skills. Try a hidden object game, like this free jewel quest game. You'll have some fun and you don't have to feel guilty about it! If you're away from your computer, smartphone or tablet, substitute a book of crossword puzzles or sudoko to fill the time and exercise your synapses. I know a lot of people who swear by these puzzles as a way to keep their mind and memories sharp.
A sedentary lifestyle is bad news in many ways. By increasing physical activity and reducing time spent sitting you can improve your brain function. In his book "Saving Your Brain," Dr. Jeff Victoroff tells readers to do everything they can to improve (or maintain) blood flow to the brain. That includes the physical exertion needed to stay in good shape as well as keeping your arteries open by watching your cholesterol, blood pressure and more. For you, that might mean walking, rather than sitting, during a soccer practice or even parking farther away when you go shopping.
This is an area that bit me during the last year or so. I didn't pay enough attention to my physical health and ended up with not-so-favorable results at my last physical exam. I got a strict set of mandates from my doctor, have been following his advice for the last 6 months, and am in much better shape now - and feeling much better. Don't overlook the value of exercise, even if it is just a walk around your neighborhood every day.
Practice Remembering Things
Memory isn't a magical function that either happens or doesn't happen. The simplest (but often the most difficult) way to remember something is to really focus on it. By removing distractions like your iPhone, and the television in the background, you'll significantly increase the probability that you'll transfer it from short term memory to long term memory and therefore remember it.
Beyond simply focusing on something you want to remember, there are lots of methods that can help you remember a wide variety of information. Mental mapping, the peg system and memorization are all tried and true methods. You can't necessarily learn a system in your spare time, but if you choose one and begin using it, you can practice it in your spare time. Lifehacker has a great explanation of three popular techniques here.
Whatever you choose, stick with it! Eventually you'll know the teacher's name without peeking at your smartphone during your next parent-teacher conference. Who knows, you might even become a World Memory Champion (yes, there is such a thing). Good luck and remember to practice!
