In today's fast-paced society, mental stress has become an unavoidable problem for many. Anxiety, insomnia, low mood, difficulty concentrating, and even depression have become common psychological problems.
With the trend of seeking natural therapies and relaxation methods, whirlpool spa hot tubs have gradually become a common choice for people to soothe their mind and body.
But the question remains: Does a spa hot tub really help relieve depression?
This article will systematically analyze the scientific principles of whirlpool spa hot tubs in regulating emotions from the perspectives of physiology, psychology, environmental factors, and relaxation mechanisms, and will also offer key precautions for its use.
Why might a spa hot tub be related to emotional health?
The core principle of a spa hot tub (Hydrotherapy Hot Tub) is to achieve relaxation of the body and soothing of the mind through warm water, circulating water, and bubble massage.
Unlike a simple bathing experience, a spa hot tub combines two mechanisms: physical stimulation and nerve relaxation.
When the body is immersed in warm water at approximately 37°C to 40°C, blood vessels dilate, muscles relax, and the nervous system receives gentle stimulation, resulting in comfort and a sense of security. This physiological balance is a crucial foundation for alleviating anxiety, tension, and even mild depression.
Therefore, researchers and health experts generally believe that spa hot tubs do not directly "cure depression," but rather indirectly alleviate depression-related symptoms by promoting relaxation, improving sleep, and lowering stress hormone levels.
How does a spa hot tub physiologically alleviate depression-related reactions?
1. The Balancing Effect of Warm Water on the Nervous System
When the body is immersed in moderately warm water, the parasympathetic nervous system is activated; this is the branch of the nervous system responsible for relaxation and recovery.
Simultaneously, the activity of the sympathetic nervous system (related to tension and stress responses) is inhibited.
This shift in the nervous system causes a decrease in heart rate, a more stable breathing pattern, and the brain to generate relaxation signals, thereby reducing anxiety.
In a whirlpool spa hot tub, the constant temperature continuously stimulates temperature receptors, prompting the body to gradually release tension and bringing a stable, calming experience.
2. Improved Blood Circulation and Metabolism
The buoyancy and pressure of water promote blood circulation, allowing oxygen and nutrients to be delivered to the brain and muscle tissue more efficiently.
A healthy circulation not only helps relieve physical fatigue but also improves brain function, enhancing attention and mood stability.
3. Stimulating Dopamine and Endorphin Release
Warm water soaking and water massage stimulate the body to release "happiness hormones"—dopamine and endorphins.
These two substances bring feelings of pleasure and calm, similar to the mental state after exercise or meditation.
Studies have found that regular use of a spa hot tub can improve mood in the short term and reduce the physiological manifestations of low mood.
What are the specific mechanisms by which a spa hot tub promotes psychological relaxation?
Depression is often associated with mental tension, mental overload, and lack of relaxation.
The unique design of a whirlpool spa hot tub can alleviate these psychological burdens on multiple levels.
1. The Soothing Effect of Sound and Tactile Stimulation
The sound of flowing water, the bubbling of bubbles, and the tactile sensation of water against the skin create a multi-sensory relaxation environment.
Psychological research shows that this rhythmic sensory stimulation effectively reduces overactivity in the cerebral cortex, making it easier to enter a meditative or tranquil state.
2. A Private and Safe Environment Provides Psychological Comfort
Unlike public hot springs, home-use spa hot tubs offer a quiet and private space.
This sense of security is especially important for those prone to depression, as it reduces external distractions and helps individuals refocus on their emotional state.
3. Closely Related to Sleep Quality
Depression is often accompanied by insomnia or poor sleep quality.
By raising body temperature and relaxing muscles, a spa hot tub helps the body cool down quickly after leaving the water, promoting sleep and establishing a more regular sleep rhythm.
Good sleep, in turn, can stabilize mood and enhance psychological resilience.
The Regulatory Effect of Spa Hot Tubs on Stress Hormones
Under prolonged stress, the body secretes large amounts of cortisol. Sustained high levels of this hormone can lead to low mood and an increased risk of depression.
Using a spa hot tub can affect cortisol levels through the following mechanisms:
• Heat stimulation promotes vasodilation, improves circulation, and helps the body metabolize excess hormones;
• Relaxation activates the parasympathetic nervous system, reducing cortisol secretion;
• Adjusts breathing rhythm: The warm water environment slows breathing, increases blood oxygen concentration, provides the brain with more stable oxygen supply, and enhances calmness.
Studies have shown that people who regularly use spa facilities have, on average, cortisol levels that are more than 20% lower than those who are under chronic stress.
This also explains why many people feel “relaxed” and “healed” after using a whirlpool spa hot tub.
Can a spa hot tub replace psychotherapy or medication?
—The answer is no.
While a spa hot tub can help relieve emotional tension and psychological stress, it cannot replace professional psychotherapy or medication.
It is more suitable for:
• Assisting in the regulation of mild low mood;
• Improving sleep and anxiety;
• Using it in conjunction with psychological counseling, exercise, or meditation.
For patients with moderate to severe depression, systematic treatment under the guidance of a doctor is still necessary. The advantage of a spa hot tub lies in providing a safe and natural way to relax, helping the body and mind regain balance more quickly.
How to maximize the relaxation effect of using a spa hot tub?
1. Control the water temperature
The ideal temperature is between 37℃ and 40℃. Too high a temperature can cause dizziness or increased heart rate, exacerbating discomfort.
2. Soaking time
Each soak should last 20 to 30 minutes. Too short a time will not achieve deep relaxation, while too long a time can easily lead to fatigue.
3. Environmental settings
Dim the lights, play soft music, and avoid external disturbances to further enhance the psychological relaxation effect.
4. Avoid using harsh cleaning agents
Keeping the whirlpool spa hot tub clean helps with a sense of psychological security, but avoid using cleaning solutions containing fragrances or chemical foams to prevent irritation to the skin and respiratory system.
5. Post-soak relaxation extension
After soaking, sit quietly for 5-10 minutes to allow the body to cool down naturally, which helps to consolidate the calming effect.
These scientific methods maximize the positive effects of spa hot tubs on psychological relaxation.
How do spa hot tubs affect the brain's relaxation response?
Spa hot tubs not only act on the body but also influence brain chemistry through temperature and tactile stimulation.
• Increased serotonin levels: Warm water stimulation promotes the release of serotonin in the brain, a neurotransmitter that regulates mood and can reduce anxiety and depression.
• Stabilized brain waves: The rhythmic sound of flowing water helps brain waves enter alpha or theta wave states, similar to the mental relaxation during meditation.
• Reduced negative thoughts: In a comfortable environment, the brain is more likely to temporarily escape negative emotional cycles, providing a window for psychological recovery.
Long-term, regular use of whirlpool spa hot tubs allows the body to learn "how to relax," forming positive emotional memories, which is highly beneficial for long-term emotional management.
Who is suitable for using spa hot tubs for emotional relaxation?
The following groups are particularly suited to spa relaxation methods to address their psychological relaxation needs:
• Those with high work stress and chronic tension;
• Those with poor sleep quality and difficulty falling asleep;
• Those who frequently experience anxiety or significant mood swings;
• Those who lack exercise and are physically and mentally exhausted.
However, those with serious cardiovascular disease, skin infections, or who are pregnant should use spa hot tubs with caution under the guidance of a doctor.
How to incorporate spa hot tubs into your daily mood management routine?
• Establish a fixed bathing time: For example, use it for 20 minutes every night before bed to help your body establish a relaxation rhythm;
• Combine with breathing exercises: Take 3-5 deep breaths while bathing to enhance parasympathetic nerve activity;
• Pair with aromatherapy or soft music: Enhance the sensory experience and promote mental calm;
• Treat it as a mind-body ritual: Maintain consistency and make bathing an important part of your daily relaxation routine.
Doing so allows the whirlpool spa hot tub to become a "psychological balance tool," helping you manage your emotions more effectively.
