🫁 Total Lung Capacity (TLC) is about 6L in healthy adults and varies by age, gender, body type, and ethnicity. Aging and conditions like COPD, obesity, or a sedentary lifestyle can reduce lung function. Keep lungs healthy by quitting smoking, eating antioxidant-rich foods, exercising, and purifying your indoor air. Try the Wim Hof Breathing Method for better focus—just practice safely and gently.

Struggling with sleep? Stress, poor diet, blue light, or an offbeat schedule could be to blame. But nature offers help: pistachios are packed with sleep-promoting nutrients like melatonin, B6, and magnesium. In fact, they're one of the most melatonin-rich plant foods — making them a safe, natural alternative to supplements. Just 2.6 oz (about 4 dozen) eaten 1–2 hours before bed can support restful, restorative sleep.
