Airless Days. A Tense Mind Works Harder

Some workdays feel harder than they should. Mouth breathing can add a hidden layer of strain, shaping concentration, tension, and the kind of mental fatigue that builds before lunch. At work, small physical stressors often become emotional ones. When breathing stays shallow or blocked, the body can stay on alert, and that steady alertness may show up as impatience, worry, or difficulty settling down. This book looks at those connections with a calm, practical eye.
It helps readers notice that tiredness, stress, and focus problems are not always separate stories.
