Soaking: A Seasonal Shift in Experience

Hot tubs are commonly seen as a winter luxury, with the warm water offering a stark and welcome contrast to chilly air. While that image holds true, picture this instead: the golden light of sunset fading, a gentle breeze brushing your skin, and you sinking into water gently warmed to the perfect degree, the massage jets easing every tight muscle. This summertime soak might just outshine even the most refreshing cold drink or perfectly set air conditioning.

Soaking in warm — but not overly hot — water during summer isn't just pleasant, it supports healthy blood flow and temperature regulation, delivering true physical and mental relief.

Why Summer Water Temperature Needs Careful Attention

Since body temperature regulation in summer depends largely on perspiration, water that's too hot can interfere with this natural cooling mechanism. Soaking in overheated water under these conditions may cause dizziness, nausea, or even heat exhaustion.

Vulnerable individuals — such as children, pregnant people, and seniors — are at greater risk. For them, entering a hot tub at inappropriate temperatures can pose significant health concerns. When water is adjusted correctly, it promotes wellness; if it's not, it becomes a hazard.

Recommended Summer Temperatures by JOYEE

For safe and enjoyable hot tub use during warmer months, JOYEE recommends:

36°C–37°C (97°F–99°F): A sweet spot for relaxation without overheating

For sensitive individuals: 34°C–35°C (93°F–95°F) offers extra safety and comfort

Avoid exceeding 38°C (100°F): Higher temps may lead to elevated body temperature too quickly

This range finds balance between the body's natural heat and ambient air temperature, ensuring a gentle and effective soak.

How to Pinpoint Your Ideal Soaking Temperature

There's no one-size-fits-all when it comes to comfort. Your perfect temperature can change based on weather conditions, humidity levels, your health, and even your emotional state. To find your ideal:

Start Conservatively: Try beginning at 95°F (35°C) and increase incrementally by 1°F–2°F (0.5°C–1°C)

Watch for Reactions: Signs like rapid heartbeat or sweating may indicate it's too warm

Use a Digital Thermometer: For accurate and safe readings

Experiment with Timing: Morning and evening ambient temps vary, so your body may react differently

How Long Is Too Long? Soaking Time Tips

Even if the water temperature feels perfect, staying too long in the tub can be counterproductive. JOYEE recommends these summer guidelines:

Most adults: 20 to 30 minutes per soak

Lower water temperatures (91°F–95°F / 33°C–35°C): May allow up to 40 minutes

Children and older adults: Limit to 10–15 minutes, with someone nearby for safety

Discontinue if symptoms occur: Any sign of discomfort—like headaches or chest tightness—should prompt an immediate exit

Staying hydrated is essential before, during, and after each soak to prevent fluid or mineral imbalances.

Boosting Heating Efficiency During Summer

Heating water in summer is less demanding, and a smart approach can save both time and energy:

Harness Solar Energy: Position your spa in a sunlit area to let nature pre-warm the water — just avoid overexposing the unit

Use a Cover: Trap the heat and speed up the warming process

Choose Well-Insulated Spas: Brands like JOYEE incorporate insulation in the tub inner shell, base, and skirt panels to reduce power consumption

Leverage Smart Thermostats: Set your desired temperature and schedule heating only when necessary

Though traditionally thought of as a winter retreat, a hot tub can be equally — if not more — beneficial during summer. Whether you're looking to unwind in solitude or enjoy a family moment, a well-maintained summer soak can deliver comfort, health benefits, and peace of mind. As temperatures climb, let your outdoor out tub become a centerpiece of your wellness routine.
