Question

In summer the urine is slightly thicker than in winter. Explain the reason.

Answer 1

In a tropical climate, as in our own country, we drink a lot of water during summer. Yet we urinate fewer times in summer than in winter and the urine passed is generally thicker. The reason is that in summer, we lose a considerable part of water through perspiration and the kidneys have to reabsorb more water from the urine making it more concentrated.
