Because of lack of established cut-offs in the literature
for characterising dehydration, euhydration or hyperhydration
from biochemical indices or water intake and
loss, it is impossible to draw conclusions on the hydration
status of the population. However, in future studies,
it will be important to enhance data on water intake and
loss with measurements of hydration indices. Conceptual
schemes on euhydration suggest that euhydration follows
a sinusoidal curve and that the ranges of water balance
for dehydration, euhydration or hyperhydration may be
wide. Shirreffs (2003) suggests that euhydration is a dynamic state between water intake and loss and that
there may be a time delay before replacing water loss or
before losing water excess. This approach is in agreement
with the observation that, in these healthy adults, the
water balance range was relatively wide
