Drinking Water Upon Awakening, a Habit Related To a Higher Total Fluid Intake and Water Intake

Abstract

A high total fluid intake (TFI) is suggested to have a potential protective effect on the kidney; however the prevalence of non‐adherence to total water intake recommendation is high. Driving individuals towards an adequate TFI requires, among other interventions, practical advice. The aim of this analysis was to evaluate whether drinking water upon awakening (before breakfast) could be a potential lever to an increased TFI. A representative sample of Indonesian children and adults (4‐65 years; N=3835; 64% women) recorded their TFI with a 24h fluid specific diary over 7 consecutive days. The results indicated that subjects (14+ y) who drank 6‐7x/week water upon awakening had a higher mean TFI, beyond the mean volume of water consumed upon awakening, then subjects who drank 蠄1/week or 2‐5x/week water upon awakening. Moreover, they had the highest contribution of water to TFI (蠄1/week: 69%, 2‐5x/week: 76%, 6‐7x/week: 81%) and the lowest contribution of sugared beverages to TFI (蠄1/week: 5%, 2‐5x/week: 4%, 6‐7x/week: 3%). The difference in mean frequency of drinking between the group drinking 6‐7x/week water upon awakening and the other groups was also larger than 1 act. Similar results were observed for children aged 4‐13 y (data not shown). This suggests that creating the habit of drinking water upon awakening potentially could be a practical advice towards an increased TFI.
