On the dark, cold mornings of January, it can be difficult to find the joy in the every day drudgery of life, but there is a science to happiness that could brighten up our winter blues.

While there's big money to be made in promising people that you can share the secret to happiness with them, there's a whole lot of science that studies what makes us happy, and how we can go about feeling better about ourselves in general.

The folks at Webpage FX have put together this handy infographic with some of the secrets of happiness, but with the science and stats to back it up, as well as telling us what the happiest countries in the world are. It turns out we need to move to Mexico, but that in terms of the temperature that maximises our happiness, an Irish summer ain't half bad. Still, we'd take a bit more sunshine.

Given that this chart scientifically proves that more sleep makes you happier, we're heading back to bed.
