Generally speaking, hot tubs are safe. There are actually many physical and emotional benefits to using a hot tub including: help with minor aches and pains, soothing sore joints and muscles, increased blood flow, reduced stress, lower blood sugar levels, improved sleep quality, and more.
Children should be supervised at all times around hot tubs. Children under 7 years old should not use hot tubs and spas. Their small bodies do not regulate temperature well and overheat quickly.
If you are pregnant or have any medical conditions that can cause sensitivity to increased body temperature, such as diabetes, circulatory problems, heart disease, or high blood pressure you should speak to your doctor before using a hot tub.
