Hydrotherapy is often cited as beneficial for increasing your blood flow and circulation, relaxing tense muscles, and relieving pressure on your body’s nervous system. Outdoor jacuzzis apply heat, massage, and buoyancy to accelerate your body’s natural healing processes and help reduce your body weight to alleviate strained muscles and aching joints. Sitting in a hot tub can also reduce your stress and help you sleep better at night. While hydration is good for your skin, it could cause skin irritation or dryness if you don’t keep your hot tub at the correct pH level. It’s essential to drink plenty of water if you plan to be in a jacuzzi for a long time, as not doing so could result in a headache, dizziness, or faintness. The key is balance and moderation.
