MOUTH-WATERING FACTS

You may have learned in school that different parts of your tongue taste different flavours. This isn’t true at all. Receptors for different tastes are spread all over your tongue.

When Jelly Belly tried to make a cheese pizza-flavoured jelly bean, the result was so bad that they used it as the basis for their vomit-flavoured bean.

Why does less sleep make the skin around your eyes puffy and dark?

When we aren’t properly rested, our body gives us a natural pick-me-up in the form of certain hormones, such as cortisol, which help to boost our energy levels and keep us awake and alert. One side effect of these hormones is that they make our blood vessels expand, and because the skin under our eyes is especially thin, all of that extra blood becomes visible and causes dark rings. The rings are easier to see in people with light skin. The extra hormones also cause our skin to hold more water, which is what causes puffiness around the eyes.

A lack of sleep can cause much bigger problems than puffy skin, though. Studies have shown that staying awake for between 17 and 19 hours impairs your physical and mental performance as much as being drunk. Tiredness has also been linked to depression, obesity, low IQ scores and feelings of loneliness.

The recommended amount of sleep for adults is between seven and nine hours a night, and it’s impossible to overstate how important a good night’s rest is. Sleeping well is beneficial for your immune system, your heart, your mental wellbeing, for regulating your appetite, managing your blood sugar levels, reducing the risk of Alzheimer’s and even improving the efficiency of vaccinations. So if you’re reading this book while propped up in bed at midnight, put it down and get some shut-eye.
