When the summer sun is blazing and temperatures are soaring, your hot tub can be more than just a place for warm soaks. With a little effort, you can turn it into a cool plunge pool and create a refreshing escape from the heat. Here’s how you can make the most of your hot tub during hot weather in the UK.

Benefits of Using a Hot Tub as a Cool Plunge Pool

1. Beat the Heat: A cool plunge provides immediate relief from the sweltering summer heat, helping you cool down and rejuvenate.
2. Improve Circulation: Alternating between warm and cool water can enhance blood circulation, benefiting overall cardiovascular health.
3. Ease Muscle Soreness: A quick dip in cool water can soothe sore muscles and reduce inflammation after a workout.
4. Enhance Skin Health: Cool water can tighten pores and improve skin tone, giving you a fresh and healthy glow.

Steps Required to Convert Your Hot Tub into a Cool Plunge Pool

1. Lower the Temperature

Begin by turning down the thermostat on your hot tub. Set it to the lowest possible setting, typically around 15°C . This temperature is comfortably cool but not too cold for a refreshing dip. A swimming pool is usually 28-30C

2b. Change the Water

If your hot tub has been filled with hot water for a while, it might be best to drain and refill it with fresh, cold water. This step ensures that the water is genuinely cool and clean.

3. Add Ice (Optional)

For an extra chill, you can add bags of ice to the water. This is particularly useful if you want to create a colder plunge experience. Just be cautious not to add too much at once to avoid shocking your system.

4. Maintain Cleanliness

Even in cool water, keeping your hot tub clean is essential. Regularly check the chemical balance and sanitize the water to prevent bacterial growth and ensure a safe, pleasant experience.
