TA🩸🫁why heat training works
blood plasma volume
regular heat exposure causes an expansion in blood plasma volume.
that’s the fluid portion of your blood.
more plasma means:
• more total blood circulating
• greater oxygen delivery per heartbeat
• lower cardiovascular strain at the same pace
in practical terms, the heart moves more oxygen with each beat.
heart rate drifts less and effort feels steadier.
this adaptation happens quickly, often within one to two weeks of consistent heat exposure.
aerobic benefit without extra impact load👍
😮💨hemoglobin and oxygen delivery😮💨
heat adaptation also improves how hemoglobin transports and releases oxygen.
with repeated exposure:
• oxygen reaches working muscles more efficiently
• muscles extract oxygen more effectively
• aerobic work feels smoother at the same output
this shows up late in long efforts. Try it out
