A Lifesaving At-Home Checkup
More importance is attached to physical fitness nowadays. However, staying fit can be expensive when going to professional agencies for medical checkups. Here we show you three ways to do medical checkup at home, try them for a rough idea about your health condition.
1 Balance On One Leg
Hold for up to 60 seconds. If you fall down early, you may be at higher risk for brain decline. In a Japanese study, 30 percent of older adults who could balance for only 20 seconds or fewer had microbleeds in the brain, an early sign of risk for stroke or dementia(痴呆). These microbleeds can affect balance, memory, and decision making.
2 Touch Your Toes
Sit with your back straight, then lean forward and try to touch your toes. Not even close? You might be at risk for heart problems. By using this test, University of North Texas researchers found that some old inflexible folks have to have the heart work harder to provide enough blood, raising the risk of heart attack or stroke.
3 Sitting To Standing
Time how long it takes to lift and lower yourself from a chair ten times as fast as you can. Senior adults who did ten repetitions in 21 seconds or fewer were less likely to die over the next 13 years than those who took longer. The test requires muscle strength, balance, and heart fitness; being slow could mean underlying disease before symptoms arise.
The above are home tests everyone could do to keep you fit and they don't require much time or money. Learn what possible dangers are hiding inside you and how to deal with them.
