We all know regular exercise keeps us fit as it helps strengthen muscles and even boosts mood. But now scientists say it does something far more surprising than just enhancing our overall health. As per researchers, exercising can sharpen and improve a hidden sense we rarely think about. A new study published in Psychology of Sport and Exercise has found that regular aerobic exercise can sharpen what experts call the ‘eighth sense’, the ability to detect and understand signals from inside your own body, such as your heartbeat, breathing, hunger, and thirst. This skill, known as interoception, could be the missing link between physical activity and better mental health.
What is the eighth sense?
Most of us are familiar with the five basic senses, which are sight, hearing, taste, smell, and touch. But experts say we also have other senses. The sixth is body position (proprioception), the seventh is balance (vestibular sense), and the eighth is interoception, the ability to sense what’s happening inside your body.
Interoception is your body’s way of sending you messages, like feeling your heartbeat, noticing when you’re hungry or thirsty, or sensing your breathing. This ‘eighth sense’ helps you understand what your body needs, take care of your health, and even handle your feelings better. But if it’s weak, it can lead to problems like anxiety, depression, and eating disorders.
The study
Researchers worked with young adults who weren’t very physically active. They divided them into two groups, where one did cycling workouts three times a week for 12 weeks, and the other stuck to their usual routine.
The workouts started with six weeks of moderate aerobic exercise, followed by six weeks of intense exercise. After the first phase, the exercise group took a test where they had to count their heartbeats without touching their pulse. The results showed they were much more accurate and confident in sensing their body’s signals.
Why it matters
When you can better understand what’s going on inside your body, you’re more likely to make timely decisions about seeking medical help. This self-awareness can also help with emotional balance, potentially lowering the risks of depression and anxiety.
How can you benefit
You don’t need a gym membership to start. Aerobic exercise includes activities like brisk walking, swimming, or cycling, anything that raises your heart rate and keeps you moving for a while. Just three sessions a week could improve not only your physical health but also your internal awareness.
