We all know that exercising is great for our bodies. It helps build strength and can even boost our moods. But recent research suggests that exercise does something even more surprising: it sharpens a little-known sense called interoception. A study published in Psychology of Sport and Exercise shows that regular aerobic activity can enhance our ability to sense signals from inside our bodies, like our heartbeat, hunger, and thirst. This skill might be key to improving mental health.
What is Interoception?
Most of us are familiar with our five senses: sight, hearing, taste, smell, and touch. But we have more than that! Beyond the sixth sense of body position (proprioception) and the seventh of balance (the vestibular sense), interoception is considered the “eighth sense.” It allows us to feel what’s going on inside us.
Interoception helps us recognize things like our heartbeat, hunger, and feelings. A strong sense of interoception can improve how we take care of ourselves and even manage our emotions. When it’s weak, it may contribute to issues like anxiety and eating disorders.
The Study Findings
Researchers studied young adults who weren’t very active. They split them into two groups: one exercised by cycling three times a week for 12 weeks, while the other stayed inactive.
The exercise phase began with six weeks of moderate exercise, then moved to six weeks of intense workouts. After six weeks, those who exercised were tested on their ability to count their heartbeats without touching their pulse. The results were revealing; the exercise group was much more accurate at sensing their internal signals.
Why Understanding Interoception Matters
Understanding what’s happening inside our bodies can help us make better health decisions. For instance, being aware of hunger can prompt us to eat, while recognizing signs of stress might encourage us to seek help. This self-awareness can also lower the risk of mental health issues such as depression and anxiety.
Getting Started with Aerobic Exercise
You don’t need a fancy gym to improve your interoception. Aerobic exercises—like brisk walking, swimming, or cycling—are effective and can easily be incorporated into your routine. Just three sessions a week can help improve both your physical health and your internal awareness.
Supporting Facts and Insights
Recent statistics highlight a growing interest in mental health linked to physical fitness. According to a survey by the American Psychological Association, nearly 70% of people find exercise beneficial for mental wellness. Experts, such as Dr. Matthew Gunter, a sports psychologist, emphasize that understanding our internal states through interoception is a crucial step toward emotional well-being.
As we engage in physical activities, we not only strengthen our bodies but also gain deeper insight into ourselves. This dual benefit makes regular exercise a simple yet powerful tool for enhancing overall health.
