Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, Volume 111, Issue 9, Page 3944-3967, 1 September 2026.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Blood flow restriction: The acute effects of body tilting and reduced gravity analogues on limb occlusion pressure

Experimental Physiology, Volume 111, Issue 9, Page 4103-4114, 1 September 2026.
Abstract Blood flow restriction (BFR) has been identified as a potential countermeasure to mitigate physiological deconditioning during spaceflight. Guidelines recommend that tourniquet pressure be prescribed relative to limb occlusion pressure (LOP); however, it is unclear whether body tilting or reduced gravity analogues influence LOP.

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

Experimental Physiology, Volume 111, Issue 9, Page 4235-4247, 1 September 2026.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Haemodynamic responses to head‐up tilt versus lower‐body negative pressure in type 1 diabetes

Experimental Physiology, Volume 111, Issue 9, Page 4089-4102, 1 September 2026.
Abstract Head‐up tilt (HUT) and lower‐body negative pressure (LBNP) both reduce central blood volume but differ in heart orientation and regional fluid shifts. Whether they evoke comparable cardiovascular regulation when matched for preload remains uncertain.

Urine electrolytes guide treatment of Gitelman syndrome and recurrent syncope—A case report

Physiological Reports, Volume 14, Issue 18, September 2026.
Abstract Syncope is a common reason for inpatient admission. Few case studies describe an association between syncope and Gitelman syndrome (GS). Herein, we present a case of a woman with hypokalemia and recurrent syncope which eventually led to a diagnosis of GS. A physiologic approach to urine electrolyte interpretation informed clinical decisions to

Bedtime tetrahydrocannabinol ingestion reduces morning orthostatic cardiovascular reactivity in adults: An exploratory study

Physiological Reports, Volume 14, Issue 17, September 2026.
Abstract Acute cannabis use and its primary psychoactive constituent tetrahydrocannabinol (THC) can induce postural dizziness, indicating increased risk of orthostatic instability. However, it is unknown if vulnerabilities persist the morning after bedtime THC consumption.
