The World Health Organization (WHO) defines vitality as the physiological reserves that help us maintain energy, adapt to stress, recover from challenges, and support healthy function as we age. Unlike blood pressure or body weight, vitality isn't measured by a single number. Instead, it reflects a combination of factors such as: ✅ Energy levels and fatigue ✅ Physical strength and movement ✅ Sleep and recovery ✅ Metabolic health ✅ Resilience to stress Think of vitality as your body's ability to meet the demands of daily life and still have energy left over. A person may be free from disease but still have low vitality if they're constantly exhausted, poorly rested, or struggling to recover from physical or mental stress. The good news? Daily habits like movement, sleep, nutrition, hydration, and stress management all play an important role in supporting vitality over time. 📱 Want an easy way to track these habits?
