In New Zealand, spa pools are a popular feature in many homes, offering a place to relax and unwind. While these pools are typically associated with warm, soothing water, there’s a growing trend among Kiwis to use their spa pools with cold water, especially during the warmer months. Whether you’re interested in the health benefits of cold therapy, looking for a refreshing dip on a hot day, or just want to explore new ways to enjoy your spa, using cold water in your spa pool can offer a range of advantages.

In this blog, we’ll discuss the benefits and practical considerations of using your spa pool with cold water, tailored for a New Zealand audience.

The Benefits of Using Cold Water in Your Spa Pool

1. Cold Therapy (Cryotherapy)
Cold water therapy, also known as cryotherapy, has gained popularity for its ability to reduce muscle soreness and inflammation. Athletes and fitness enthusiasts in New Zealand increasingly use cold water immersion after workouts to aid recovery. The cold water constricts blood vessels, reducing swelling and promoting quicker muscle recovery. For those with an active lifestyle, a cold spa pool can be an effective way to ease muscle pain and improve post-workout recovery times.

2. Improved Circulation
Cold water immersion stimulates circulation as your body works to maintain its core temperature. This helps improve blood flow, reduce swelling, and remove toxins from the body, making cold water a great option for improving overall cardiovascular health. Cold exposure also helps to oxygenate the blood, making it beneficial after physical exertion or a long day on your feet.

3. A Refreshing and Invigorating Option
During the hot New Zealand summer months, especially in regions like Auckland and Northland, a spa pool filled with cold water offers a refreshing escape from the heat. Instead of feeling weighed down by the sun, a quick dip in cold water can leave you energised and revitalised. It’s the perfect way to cool off after outdoor activities like hiking, beach outings, or simply spending time in the garden.

4. Boosting Mood and Mental Clarity
Cold water immersion isn’t just good for the body—it’s also beneficial for the mind. The sudden cold shock triggers an endorphin release, which can boost your mood and help with mental clarity. Many people report feeling more focused and less stressed after using cold water therapy. Whether you need to clear your head after a busy workday or reset your mood, a cold water spa session can be a great tool for mental well-being.

5. Lower Energy Costs
Using your spa pool with cold water can save you money on energy bills, especially during the summer months when heating costs tend to rise. Running a spa heater to keep the water warm can add up quickly, but cold water requires no heating, making it a cost-effective way to enjoy your spa year-round. You’ll also prolong the life of your heater by giving it a break during the warmer seasons.

Practical Considerations for Using Cold Water in Your Spa Pool

While the benefits of using cold water in your spa pool are clear, there are some important considerations to keep in mind to ensure a safe and enjoyable experience.

1. Gradually Lower the Water Temperature
If you’ve been using your spa pool with warm water, it’s important to lower the temperature gradually when transitioning to cold water. Most spa pools allow you to adjust the temperature in small increments, so you can slowly reduce it over time to let your body acclimate. The ideal temperature for cold water therapy is typically between 10°C and 15°C. By reducing the temperature gradually, you can avoid the shock that comes with sudden cold exposure, making the experience more comfortable.

2. Keep Your Sessions Short
While cold water immersion has numerous benefits, it’s essential to limit the time spent in cold water to avoid potential health risks, especially for those new to it. Short sessions of 1-2 minutes are ideal for beginners, allowing your body to adjust. As you become more accustomed to cold water, you can gradually increase the duration of your sessions, but it’s important to listen to your body. Prolonged exposure to very cold water can lead to hypothermia, so always stay aware of how your body is responding.

3. Be Aware of Health Conditions
Not everyone is suited to cold water immersion. If you have heart conditions, respiratory issues, or poor circulation, cold water could exacerbate these problems. For those with health concerns, it’s always a good idea to consult a doctor before introducing cold water into your spa pool routine. Cold water can increase blood pressure and cause a rapid heartbeat, so medical advice is crucial if you have any pre-existing conditions.

4. Maintain Regular Water Quality Checks
Although cold water inhibits bacterial growth more than warm water, it’s still essential to maintain good water quality. Regular cleaning, chemical balancing, and filter maintenance are necessary to keep your spa pool hygienic, even if you’re using it with cold water. Cold water does not eliminate the need for proper spa pool care, so be sure to keep an eye on pH levels, sanitiser levels, and ensure filters are clean to avoid water quality issues.

5. Seasonal Versatility
One of the best things about using cold water in your spa pool is the flexibility it offers year-round. During the hotter summer months, you can enjoy a cold dip to cool down, and as the seasons change, you can easily switch back to warm water for a more traditional spa experience. This versatility allows you to get more use out of your spa pool, regardless of the weather, making it a worthwhile investment that can adapt to your changing needs and preferences throughout the year.

Practical Tips for Optimising Your Cold Water Spa Experience

Now that we've covered the benefits and initial considerations of using your spa pool with cold water, let's explore some additional tips to ensure you get the most out of this unique experience. Whether you're using your spa for health reasons, cooling off on a hot day, or simply for relaxation, these tips will help you enjoy your cold water spa safely and comfortably.

1. Prepare Your Body for Cold Water Immersion
Cold water can be a shock to your system, especially if you're new to it. To ease the transition, consider these preparation tips:

• Start with a Warm Shower: Before entering the cold water, take a warm shower to slightly raise your body temperature. This helps to make the switch to cold water less jarring.

• Enter Slowly: Gradually step into the spa rather than jumping in. This allows your body to adjust to the cold temperature and makes the experience more manageable.

• Focus on Breathing: Cold water can make your breathing quick and shallow. Practise slow, deep breaths to help your body relax and acclimate to the temperature change.

2. Create a Relaxing Atmosphere
Though cold water can be invigorating, setting the right mood can enhance the overall experience:

• Add Ambient Lighting: Soft lighting around your spa, like fairy lights or waterproof LED candles, can create a calming ambiance, especially in the evening.

• Play Music or Nature Sounds: Create a playlist with soothing music or nature sounds to play while using the spa. This can help distract from the cold and make the experience more enjoyable.

• Aromatherapy: Using essential oils in a nearby diffuser, like lavender or eucalyptus, can elevate the relaxation aspect of your spa experience.

3. Be Mindful of Timing and Weather
The time of day and weather conditions can impact how comfortable and enjoyable your cold water spa experience will be:

• Morning Sessions: A cold water dip in the morning can energise you for the day ahead, making it a great way to wake up.

• Evening Sessions: In the evening, cold water can be refreshing after a warm day. However, avoid using very cold water right before bed as it can interfere with your body's natural cooling processes needed for sleep.

• Weather Considerations: Avoid using your cold water spa on especially cold or windy days, as this can make the experience too uncomfortable. Instead, choose mild or warm days for the best experience.

4. Warm Up After Your Session
After exiting your cold water spa, it’s important to warm up your body gradually. Here are a few ways to do that effectively:

• Towel Off Quickly: Dry off as soon as you leave the spa to prevent further exposure to cold air.

• Dress in Warm Clothes: Put on warm clothing immediately after your session, such as a thick robe or cosy jumper, to retain body heat.

• Have a Warm Drink: Sipping on herbal tea or hot water with lemon can help raise your internal body temperature and make the transition from cold water more comfortable.

• Take a Warm Shower: If you're feeling particularly cold, a short, warm shower can help bring your body temperature back to normal.

5. Pay Attention to Your Body's Signals
Cold water immersion offers many benefits, but it’s essential to monitor how your body responds. If you notice any of the following signs, it’s time to exit the spa:

• Shivering: Shivering is a sign that your body is losing heat. If you start to shiver, wrap up and warm yourself immediately.

• Numbness: If your fingers, toes, or other extremities start to go numb, this indicates that your body is struggling with the cold, and it’s time to stop.

• Dizziness or Lightheadedness: If you feel dizzy or lightheaded, it could indicate that the cold water is affecting your circulation or blood pressure, and you should exit the water promptly.

6. Make It a Social Experience
Sharing the cold water spa experience with friends or family can make it more fun and engaging:

• Cold Water Challenges: Set up friendly challenges to see who can stay in the cold water the longest. Be mindful of safety and time limits.

• Post-Workout Recovery Together: If you or your friends are into fitness, using the cold spa pool together after a workout can enhance the recovery process.

• Cooling Down Together: On hot days, inviting friends or family to join you for a refreshing cold water dip can be a great way to cool down while enjoying each other’s company.
