The tech world has certainly been up to speed about it for a while now, with the likes of Google availing sleeping pods for those of their employees who can’t resist the strong and natural urge to get some shut-eye as the day wears on. And that’s exactly what it is — a natural urge, which surely must be natural since pretty much all of us experience it. For people working in the tech world and for entrepreneurs who are working for themselves, setting their own working schedule and doing their own thing, giving in to Mother Nature in this way and taking a little nap is a great way to recharge your batteries for the final stretch of work ahead of you over the remainder of the day. But for those for whom this isn’t an option (and for tech sector workers or self-employed people who prefer to stay awake), Citrix GoToMeeting has put together a great infographic featuring all of 15 snacks which are great for boosting your energy levels and keeping you alert throughout the day. Munch down on a different one of these each day and your daily energy slump will be a thing of the past.
