Fitness trackers — such as the FitBit, Jawbone UP24 and Nike+ FuelBand — collect data about your activity levels and sleep patterns, then send the information to your computer or smartphone via low-level radio-frequency waves.
“We have no information whatsoever on the long-term health effects of wearable fitness-tracking devices,” says Devra Davis, PhD, MPH, an epidemiologist and founder of the Environmental Health Trust. “The lack of proof of harm is not evidence of safety. You have to decide for yourself if that’s a risk you want to take.”
The non-ionizing waves emitted by wireless trackers are similar to those of cell phones, which have been classified as “possibly carcinogenic to humans” by the World Health Organization’s International Agency for Research on Cancer. The National Cancer Institute recommends limiting cell-phone calls that involve phone-to-head contact.
But unlike cell phones, activity trackers are meant to be worn on the body around the clock.

The Republic of Czech is renowned for it’s beer and the consumption of beer is typically greater compared to many other European countries.

You don’t always have to go on an extreme diet to lose weight or keep fit, and it can just come down to eating sensibly. Snack swapping can help you improve your eating habits and to help you get started we’re providing you with a selection of good substitutions.
Popcorn can be a lot healthier and lower in calories than crisps, and by making this swap you could start to feel much healthier. It’s so easy to eat your way through several bags of crisps each day, and popcorn can be just as filling but actually healthier, especially if it is the type that doesn’t contain a lot of sugar or salt.
Another good substitution is swapping a sandwich for sushi. Sandwiches can be quick and convenient, especially if you’re eating in a hurry at work, but sushi can be purchased at the same price, and you’re likely to get more protein, less fat and fewer calories.
