Effect of Permissive Dehydration on Induction and Decay of Heat Acclimation, and Temperate Exercise Performance.

Frontiers in Physiology, 2016
Purpose: It has been suggested that dehydration is an independent stimulus for heat acclimation (HA), possibly through influencing fluid-regulation mechanisms and increasing plasma volume (PV) expansion.

Associations Between Caffeinated Beverage Consumption and Blood Pressure Parameters in Nurses Based on 24‐Hour Ambulatory Blood Pressure Monitoring: A Cross‐Sectional Study

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background and Aims Nurses frequently consume caffeinated beverages to manage fatigue, but their associations with ambulatory blood pressure are unclear. This cross‐sectional study examined associations between caffeinated coffee, tea, and energy drinks and blood pressure parameters in nurses.

High skin temperature and hypohydration impair aerobic performance [PDF]

Experimental Physiology, 2012
This paper reviews the roles of hot skin (>35°C) and body water deficits (>2% body mass; hypohydration) in impairing submaximal aerobic performance. Hot skin is associated with high skin blood flow requirements and hypohydration is associated with reduced cardiac filling, both of which act to reduce aerobic reserve.

Increased Vulnerability to Dehydration Due to Heat Stress and Drought Across Reproductive States for Pastoralist Women in Northern Kenya

American Journal of Human Biology, Volume 38, Issue 7, July 2026.
ABSTRACT Objectives Extreme weather events, like drought and heat stress, make it harder to meet water needs in water‐insecure settings, particularly vulnerable groups. This study examines how short‐term (heat stress) and long‐term (drought) water stress affects hydration status across reproductive states (pregnant, lactating, compared to non‐pregnant ...

Fat Oxidation, But Not Subcutaneous Adipose Tissue Lipolysis, Differs Between Males and Females During a Treadmill‐Based Heat Tolerance Test

European Journal of Sport Science, Volume 26, Issue 5, May 2026.
ABSTRACT This study aimed to determine whether fat metabolism differs between males and females when exposed to extreme exercise‐heat stress. Physically active males (n = 11, 23 ± 4 years, 81.7 ± 11.8 kg, body fat 16.4 ± 6.6%) and females (n = 13, 25 ± 4 years, 60.4 ± 7.1 kg, 24.4 ± 6.7%) completed a 2‐h exercise‐heat tolerance test (40° $\boldsymbol{{}
