The Benefits of Alternating Hot and Cold Water in the Bathroom: Improving Health and Mood
Since ancient times, the hot and cold bath has been known for its beneficial effect. Today, scientists are discovering more benefits of using cold water in the bath, such as strengthening the immune system and improving mental mood.
The Alternating Hot and Cold Water Therapy: How It Works
The technique of alternating hot and cold water in the shower, known as "hot and cold water therapy", involves alternating hot water for 3-4 minutes and cold water for 1 minute, repeated for 20 minutes.
This switching creates a "pumping mechanism" that improves blood circulation, pushing more oxygen-rich blood to the muscles and tissues near the skin. At the same time, deoxygenated blood returns to the lungs to pick up new oxygen, offering benefits such as:
- Reduction of muscle soreness after exercise
- Faster muscle recovery
Scientifically Proven Benefits of Hot-Cold Water Alternation
A study from the Academic Medical Center Amsterdam showed that a daily "Scotch" shower can reduce sickness absence by almost 30%. Scientists attribute this effect to an increase in white blood cells, which strengthen the immune system.
The Effect of Hot-Cold Water Alternation on the Skin
Although this treatment has not been proven to prevent skin aging, many experts believe that it improves blood flow to the skin's tiny capillaries. Mr George Tzenichristos from The Hale Clinic in London argues that this better circulation improves the function of fibroblasts, the cells that produce collagen, helping to maintain skin elasticity and firmness.
Mental Health and Hot-Cold Water Alternation
Research from the Commonwealth University in the USA. showed that daily alternating between hot and cold water in the shower can significantly improve mood in just two weeks. This is attributed to increasing levels of the neurotransmitter noradrenaline, which is associated with improved mood and may even help with depression.
Alternatives: The Benefits of Hot Water
For those who are not thrilled with the idea of a cold shower, there is also the option of hot water. A study from Loughborough University showed that bathing in 40 degree Celsius water for an hour can burn up to 140 calories and improve blood sugar control.
