The drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness, and subsequently result in drowning. The water temperature should always be checked with an accurate thermometer before enterins a spa or hot tub. Persons taking any medication which induces drowsiness, such as tranquilizers, antihistamines or anticoagulants should not use spas or hot tubs. Manage your pool heating as you manage your home heating and air conditioning to minimize the cost of operating your heater without sacrificing swimming comfort. The National Spa and Pool Institute and the American Red Cross recommend this water temperature for competitive swimming.
