You probably were. Tight shoulders and ribs inhibit inhalation. Once you loosen up and grow stronger, you will increase the volume of your ribcage. As you do that, the tissues of the lungs unfold or stretch to fill them. Some corners of your airway will get cool/fresh air for the first time in ages. It all feels pretty odd -- tickles, itches, or even a fearful asthma response.

Just reading this comment made my lungs feel constricted and caused a subconscious deep breath to fill them up.

Wow, so it wasn't just my imagination, good to know.

What's the clinical definition of "tight shoulders" and is it shown to correlate significantly with inhalation problems?

  You need a cite to understand that the bellows of the ribs might be constrained by tension held in the intercostals and shoulder girdle? Lol. Here ya go. https://academic.oup.com/ptj/article/86/3/345/2805157 https://academic.oup.com/ptj/article/86/3/345/2805157 The diaphragm is also a muscle, and can be trained. https://www.sciencedirect.com/science/article/abs/pii/S1746068914000650#:~:text=Our%20results%20demonstrate%20that%20diaphragm,respiratory%20pressures%20and%20pulmonary%20function https://www.sciencedirect.com/science/article/abs/pii/S17460....

    First paper does not seem to support your point, as it is about respiratory musculature, not shoulders.

  >What’s the clinical definition of “tight shoulders”? Chronic contraction of the upper trapezius. >[I]s it shown to correlate significantly with inhalation problems? There’s not much in the medical literature beyond noting that that upper trapezius is an accessory muscle in expanding the lungs. (MDs correct me if this is wrong.) Physiotherapy research is less rigorous but more expansive on the point. See e.g. Kim et al. >BACKGROUND: Forward head posture (FHP) causes changes in the strengths and rigidities of cervical muscles. OBJECTIVE: The aim of this study was to investigate correlations between FHP and respiratory functions and the muscle activities of respiratory accessory muscles in young adults in their 20s. METHODS: A volunteer sample of 33 healthy young adults participated in this study. Craniovertebral angle (CVA), cranial rotational angle (CRA), vital capacity (VC), forced vital capacity (FVC), forced expiratory volume at 1 second (FEV1), peak expiratory flow (PEF), maximal voluntary ventilation (MVV), and sternocleidomastoid (SCM) and upper trapezius activity ratios were measured. RESULTS: Significant positive correlations were found between CVA and VC, FVC, FEV1, PEF, and MVV, and a significant negative correlation was found between CVA and SCM activity ratio. Significant negative correlations existed between CRA and VC and FVC, and significant positive correlations between CRA and SCM and upper trapezius activity ratios.
