Once a week enough exercise the origin should be two and a half hours

Once a week enough exercise, the origin should be two and a half hours - So far, the experts always suggest that we diligently exercising regularly every day. But a recent study says that exercise once a week is enough, as long as we do it for two and a half hours in a row.

According to researchers from Queens University, anyone who can work out for 150 minutes at the weekend were able to get the same benefits as those who regularly exercise every day.

"Sometimes a lot of people are too busy in the active work so they can not exercise regularly. So long as they can meet the time 150 minutes a day to exercise alone, it has included healthy," explained lead researcher Dr. Ian Janssen, as quoted by the Daily Mail.

Health guidance is suggested that adults do physical activity every day for a total of 150 minutes. But there is no definite rule whether the exercise should be done 20-25 minutes every day, or 150 minutes a day greetings directly.

This study also proves that the health benefits of exercise 150 minutes to be had, no matter whether a person do it little by little each day or directly in a single day.

The results subsequently published in the journal Applied Physiology, Nutrition and Metabolism.

Soft Lens Not Enough Just Soaked

Soft Lens Not Enough Just Soaked | Unlike eyeglasses, contact lenses are not easy to shift, dewy or dusty so it is more comfortable and does not interfere with the appearance. However contact lenses require maximum care to keep them clean and free of bacteria.

Especially for soft contact lenses, it is recommended to clean and scrub with cleaning solution before soaking overnight. This way considered as the best way to kill most of bacteria, and prevent eye infections. As known some types of bacteria can penetrate the soft lens.

"Although some cleaning solutions mentioned" do not need to be rubbed again ", but scrubbed and rinsed before immersion is the most effective in any type of contact lenses,"

said Hua Zhu, of Brien Holden Vision Institute, Australia.

In his research, he examined some kind of contact lens cleaning solutions, including products that claim does not need to be buffed (no rub), to eliminate bacterial or fungal cultures derived from commercial contact lens, whether it is a type of silicone or hydrogel lenses.


The researchers found that: the cleaning solution would be more effective if we use the technique of "rub and rinse" before soaking lenses. In contrast, if only "soak" it will leave bacteria on contact lenses.

Meanwhile, the technique of "rinse only" will improve hygiene when cleaning solution containing preservative used polyguad. However, the technique of "rinse only" less effective cleaning one or two silicone hydrogel lens of bacteria.

"Skip the soft lens brush will leave a lot of bacteria. If microorganisms were attached to the surface of the contact lens, it will be more resistant to disinfectants," said Hua.
