The team at the credible fitness resource, Fitrated.com has done their own research and found out that the risk of getting an infection in a gym is much greater than that in a public restroom: the study found 326 times more bacteria in a gym than on any toilet seat. Besides, more than 70 % of the bacteria are potentially dangerous for people as they can easily cause a cold or a skin disease.

The most contaminated places in gyms were stationary bikes and treadmills. Specialists recommend taking the simplest safety precautions: use anti-bacterial wipes, don’t touch your face with your hands and don’t walk barefoot in the locker room or the shower.

The scientists from the King’s College of London, UK, conducted an experiment with 42 perfectly healthy volunteers of normal weight who slept less than 8 hours a night. Half of the participants had to sleep less than usual for one month. Also, the participants were asked to write down everything they ate. At the end of the experiment, the duration of sleep increased by 21 minutes on average. The analysis showed that even this insignificant increase in sleep led to the decrease of consumption of sweet food by 10 grams a day which is one-third of the daily norm. Sleeping longer also led to a decrease in the interest of carbohydrates.
