1. It's hot outside! How much water should I be drinking to keep my kidneys healthy?
The amount of fluid to drink is proportional to the amount of fluid loss and the ambient humidity. If you are in a warm dry environment in the absence of sweating, drinking 4 to 6 eight ounce glasses of water per day may be enough. If you are working and sweating profusely, water and fluid intake may need to exceed on liter per hour (one liter = 30+ ounces). If you are in a warm and humid environment and sweating and working, sweat losses may be 1 to 2 liters per hour and this plus basal intake of 4 to 6 eight ounce glasses may be need to be ingested.
2. I'm used to exercising outdoors, but lately it's been too hot. Do you have any suggestions for beating the heat and staying active?
Swimming is an excellent physical activity and does not stress weight bearing joints. Walking in water can be a very good physical activity for seniors and will minimize stress on backs, hips and knee joints, while maintaining mobility. Bicycling with air moving past will help to keep you cool. Exercising in an air-conditioned club may be a break from the outdoors on hot and sticky days. Walking at indoor malls has become quite popular in some urban areas and early morning or late day social clubs have been known to organize such activities. Walking in the early cool of the day is also another way to beat the heat.
