When we are stressed, when we are tired and overwhelmed, it’s easy to hold our breath without even knowing it. And when we do that, we deprive ourselves of oxygen, which, in turn, limits our ability to think clearly in the moment and do things like problem-solving and affect-regulation.
Researchers found, on average, participants who reported more stress in their lives experienced a steeper decline in functional health over three years, and that link between stress and functional health decline was stronger for chronologically older participants.
However, subjective age seemed to provide a protective buffer. Among people who felt younger than their chronological age, the link between stress and declines in functional health was weaker. That protective effect was strongest among the oldest participants.
