Influence of body dimensions and sex on cold-induced vasodilation.

Cold-induced vasodilation (CIVD) is a physiological response characterized by cyclic vasodilation occurring within 5-10 min of cold exposure, predominantly in the fingers and toes. This study aimed to determine the roles of body dimensions, specifically surface-to-mass (SM) ratio and sex in modulating CIVD responses. Thirty-nine participants (mean ± SD age: 24 ± 3 yr; height: 174 ± 28 cm; weight: 75.

Sex differences in thermophysiological responses of elderly to low-intensity exercise during uncompensable heat strain.

Purpose: The rising frequency of extreme heat events poses an escalating threat of heat-related illnesses and fatalities, placing an additional strain on global healthcare systems. Whether the risk of heat-related issues is sex specific, particularly among the elderly, remains uncertain.

Methods: 16 men and 15 women of similar age (69 ± 5 years) were exposed to an air temperature of 39.

The effect of breathing exercises and mindset with or without cold exposure on mental and physical health in persons with a spinal cord injury-a protocol for a three-arm randomised-controlled trial.

Study Design: A three-arm randomized controlled trial.

Objectives: To investigate the effects of the Wim Hof Method (WHM), with (WHM-C) and without cold exposure (WHM-NC), on mental and physical health in persons with chronic spinal cord injury (SCI).

Setting: Rehabilitation centre (assessments and once-weekly intervention sessions) and home-based (daily intervention sessions).

Body Core Temperature Assessment in Emergency Care Departments.

Background: There is concern that the values provided by devices using infrared thermometry in emergency departments (EDs) do not reflect body core temperature accurately.

Objectives: Evaluation of three thermometers commonly used in the ED.

Methods: Two infrared ear thermometers and an infrared forehead thermometer were evaluated using 1) the Voltcraft IRS-350 calibration device, 2) comparing temperature values to a rectal end-exercise temperature (T-RECT) of 38.

Effects of heat and personal protective equipment on thermal strain in healthcare workers: part B-application of wearable sensors to observe heat strain among healthcare workers under controlled conditions.

Purpose: As climate change accelerates, healthcare workers (HCW) are expected to be more frequently exposed to heat at work. Heat stress can be exacerbated by physical activity and unfavorable working requirements, such as wearing personal protective equipment (PPE). Thus, understanding its potential negative effects on HCW´s health and working performance is becoming crucial.
