Hot to Cold Contrast Therapy Using a Lay-Z-Spa and Ice Bath: Benefits, Science & How-To Guide
Hot to cold contrast therapy has taken the wellness world by storm, and for good reasons. And, since this is a practice used by wellbeing pioneers such as the Egyptians, Greeks and Romans, you know it is something that works.
Here we break down what it is, why it's good for you, and how to do hot to cold contrast therapy with Lay-Z-Spa.
Athletes, fitness enthusiasts and anyone looking for ways to improve wellness are embracing this dynamic practice to enhance recovery, reduce inflammation, and boost overall mental and physical wellbeing. By combining the heated relaxation of a Lay-Z-Spa hot tub with the invigorating contrast of an ice bath, you can harness powerful physiological effects that are backed by science.
What is contrast therapy?
Contrast therapy, also known as hot to cold immersion therapy, involves alternating between hot and cold water exposure. The method stretches back to traditional hydrotherapy practices and is designed to stimulate blood flow, reduce muscle soreness, and enhance recovery through temperature-induced vascular changes.
The Science behind hot to cold contrast therapy
When your body is immersed in hot water (around 37-40°C), blood vessels dilate, promoting increased blood flow and muscle relaxation. This process, known as vasodilation, helps flush metabolic waste from tissues.
In contrast, cold exposure (typically 10-15°C) causes vasoconstriction, where blood vessels narrow, reducing inflammation and temporarily numbing nerve endings. Alternating between these states improves circulation, enhances lymphatic drainage, and stimulates the parasympathetic nervous system for better recovery and stress reduction.
Contrast therapy can:
- Support healthy circulation*
- Improve flexibility and joint function
- Reduce muscle soreness*
- Help with stress & nervous system regulation
- Mental resilience & confidence
- Support immune & metabolic health
- Reduce delayed onset muscle soreness (DOMS)*
- Accelerate muscle recovery post-exercise*
- Enhance sleep quality and immune response*
*Fully backed by scientific studies
Lay-Z-Spa hot tub for heat therapy
Lay-Z-Spa hot tubs are an ideal tool for at-home contrast therapy. They are convenient, portable, and maintain consistent water temperatures that can be set to suit your contrast therapy needs. With built-in HydroJets or AirJets, they also provide a gentle massage, further relaxing muscles and aiding recovery.
Lay-Z-Spa ice bath for cold contrast
Lay-Z-Spa ice baths deliver the necessary cold shock to trigger the body's natural recovery mechanisms. The cold immersion complements the heat exposure from the Lay-Z-Spa hot tub, making the contrast therapy more effective.
How to do hot-cold contrast therapy at home
Preparation:
- Lay-Z-Spa temperature: Heat to 37-40°C (98.6-104°F)
- Ice bath temperature: Chill to 10-15°C (50-59°F)
- Have towels and warm clothing ready for after the session
Step-by-Step guide:
- Hot Phase: Immerse yourself in a Lay-Z-Spa hot tub for 5-10 minutes. Focus on deep breathing and muscle relaxation.
- Cold Phase: Transition to a Lay-Z-Spa ice bath and submerge up to your chest for 1-3 minutes. Expect an initial shock response; breathe deeply to adapt.
- Repeat: Alternate between hot and cold for 2-3 cycles, always ending with cold if recovery is the goal, or with hot if relaxation is the goal.
Post-session tips:
- Hydrate well.
- Avoid intense activity immediately after.
- Consider light stretching or meditation to prolong the benefits.
