10 second balance test predicts health: Failure linked to 84pc higher death risk

A simple 10-second balance test can measure your health status! A doctor teaches an easy balance test that can be done at home, stating that if you can't hold the position for 10 seconds, your risk of heart disease could increase by a whopping 50 percent. For those unable to reach 10 seconds, he recommends three major methods to improve balance, effective with just five minutes of daily practice.

According to a report by mainland media Life Times, Dr. Sun Dong-sheng, chief physician of the geriatrics department at Zhejiang Provincial People's Hospital, stated that numerous studies have found the body's balance ability acts like a mirror of health, reflecting the condition of the heart and cerebrovascular system. To test balance, scientists have designed various simple methods, among which the "Single-Leg Stance Test with Eyes Closed" is one assessment method.

How to perform the Single-Leg Stance Test with Eyes Closed

1. Stretch your arms out horizontally to both sides. Stand upright with legs together and toes pointing straight ahead.
2. When starting the test with eyes closed, use your dominant leg as the supporting leg to maintain the standing posture.
3. Bend and lift the knee of the other leg, ensuring it doesn't touch the supporting leg.

Doctors point out that a generally healthy person should be able to maintain the single-leg stance with eyes closed for over 10 seconds. Research shows that every one-second reduction in this test corresponds to the body aging by 0.7 years. Furthermore, Professor Yamada from Kyoto Prefectural University in Japan stated this test effectively assesses muscle strength and balance function, helping determine the body's aging degree. Regardless of gender or age, those who can stand for over 9 seconds typically have younger bodies. A 12-year study published in the British Journal of Medicine found a relationship between balance and mortality: middle-aged and older adults unable to stand on one leg for 10 seconds had nearly twice the risk of dying within the next decade compared to those who could maintain balance.

3 Major Health Risks Associated with Inability to Maintain Single-Leg Stance:

1. Heart Disease Risk: Studies indicate that people who cannot complete the 10-second single-leg stance test have an 84pc increased risk of all-cause mortality and a 50pc higher risk of developing heart disease within the next 10 years. This is because individuals with poorer balance often have poorer lower limb blood circulation, forcing the heart to work harder to maintain blood supply, leading to long-term cardiac overload. Additionally, if the autonomic nervous system regulating balance is dysfunctional, it can cause drastic blood pressure fluctuations, damaging vascular endothelial cells and negatively impacting heart and brain vascular health.
2. Stroke Risk: Up to 83pc of stroke patients experience significant balance dysfunction. These patients with poor balance have twice the risk of a secondary stroke compared to others. The key reason is that stroke can lead to insufficient blood supply to the cerebellar balance center. Furthermore, decreased balance ability limits patients' activity levels, slowing blood circulation and making them more prone to blood clots.
3. Cognitive Decline Risk: People with declining balance ability have a 40pc increased risk of memory deterioration within 5 years, and their risk of developing Alzheimer's disease rises by 30pc.

Declining Balance Increases 4 Risks, Slows Brain Reaction Speed

Professor Zhang Yi-min from the Key Laboratory of Exercise and Physical Fitness at Beijing Sport University pointed out that whether standing, sitting, squatting, or riding, the human body relies on good balance ability. The report states that this balance function is achieved through the coordinated work of multiple systems including vision, muscle strength, and the nervous system. When balance ability declines, it may trigger the following 4 potential risks, which can be fatal in severe cases.

1. Increased Risk of Fatal Falls: Professor Gou Bo from the School of Sports and Health Sciences at Xi'an Physical Education University stated that falls are the leading cause of injury-related death among adults aged 65 and above in China. According to a World Health Organization report, falls cause up to 300,000 deaths globally each year.
2. Dizziness and Tinnitus Symptoms: The vestibular organ in the inner ear not only maintains body balance but is also closely related to symptoms like nausea, vomiting, and dizziness. For example, excessive motion stimulation during travel can interfere with the normal function of the vestibular system, inducing motion sickness.
3. Significantly Increased Joint Injury Risk: Professor Gou Bo explained that when balance ability weakens, it limits athletic performance and reduces opportunities for muscle training. Long-term, this hinders skeletal function, leading to a chain of health issues including ligament and meniscus injuries, cartilage wear, and premature joint degeneration.
4. Decreased Reaction Ability: Researchers from the University of Edinburgh in the UK noted that the body's reaction speed comprehensively reflects the coordination of various parts, and there is a correlation between reaction ability and balance. Therefore, balance training can effectively improve reaction ability; conversely, when balance function declines, it also slows down brain reaction speed.

3 Major Reasons Weakening Balance; Sitting for 2 Hours Reduces Balance by 5pc

The report also pointed out that while declining balance is commonly associated with aging, factors like obesity, smoking, and lack of exercise can also impair balance. Additionally, the following 3 major reasons reduce balance ability:

1. Natural Aging: Starting from age 40, the function of the vestibular system, responsible for dynamic balance control, begins to decline. By age 70, its sensitivity is only 40pc of that in youth. Muscle mass decreases by about 1pc annually, with significant weakening of lower limb strength directly affecting balance.
2. Medication Side Effects: For instance, taking blood pressure medication might cause postural hypotension, leading to unsteadiness when standing up. Antidepressants like Sertraline might interfere with nerve conduction, thereby reducing balance ability.
3. Unhealthy Lifestyle Habits: Prolonged sitting can cause gluteal muscles to become inactive. Research shows that sitting continuously for 2 hours reduces balance ability by 5pc. Chronic sleep deprivation disrupts the rhythmic regulation function of the cerebellum, even causing gait instability similar to a drunken state.
