What happens if you stay in a whirlpool spa hot tub for too long?

Whirlpool spa hot tubs not only provide users with a comfortable environment, but also help relieve muscle tension, improve blood circulation, and promote physical and mental relaxation through water flow and massage systems.

While whirlpool spa hot tubs provide these benefits, using them for too long may bring some health risks. Many people may ignore the potential harm of over-immersion while enjoying the comfort brought by whirlpool spa hot tubs.

This article will explore in detail the health problems that may occur if you stay in a whirlpool spa hot tub for too long, and help users understand how to properly use and maintain the whirlpool spa hot tub to avoid the negative effects of over-immersion.

The principle and precautions of whirlpool spa hot tub

Whirlpool spa hot tubs usually provide powerful massage effects and warm water flow through built-in water pumps, nozzles, and heating systems. The warm water and water flow of this bathtub help relieve muscle pain, reduce stress, and even help improve sleep. However, staying in hot water for a long time, especially at high temperatures, the body's physiological response may cause a series of discomforts.

1. The effect of water temperature

The water temperature of a whirlpool spa hot tub is usually between 37°C and 40°C, which is a warm and comfortable water temperature range that allows people to relax and enjoy the massage effect. However, when the water temperature is too high or you stay in hot water for a long time, the body may have difficulty regulating itself, resulting in symptoms such as overheating or dehydration.

2. The effect of water flow

The intensity of the water flow in a whirlpool helps massage muscles and promote blood circulation. If the water flow is too strong and acts on a certain part of the body for a long time, it may cause local blood flow abnormalities, which may cause discomfort.

What happens if you stay in a whirlpool spa hot tub for too long?

Although whirlpool spa hot tubs can bring many benefits to the body, they may bring a series of health risks if they are not used properly or soaked in them for a long time. Here are some of the main potential health problems.

1. Dehydration

The water temperature of a whirlpool spa hot tub is usually high, which can easily cause the body to lose water. In warm water, the body's blood vessels expand and sweat glands begin to secrete more sweat to maintain body temperature regulation. When users stay in a whirlpool spa hot tub for too long, the amount of water lost from the body increases, which may lead to symptoms of dehydration.

Symptoms of dehydration include thirst, fatigue, dizziness, dry skin, and decreased urine output. If dehydration lasts for a long time, more serious problems may occur, such as heat stroke, weakness, and increased heart pressure.

2. Low blood pressure

The water temperature of a whirlpool spa hot tub causes blood vessels to dilate, which leads to increased blood flow. If you stay in the tub for too long, abnormal blood circulation may cause low blood pressure, which manifests as dizziness, drowsiness, fatigue, and other symptoms.

For people with poor cardiovascular health, soaking in hot water for a long time may cause blood pressure to drop further, increase the burden on the heart, and thus affect health.

3. Increased heart rate and difficulty breathing

The higher temperature in a hot tub will have a certain effect on the heart. When the body temperature rises, the heart will speed up the pumping of blood to help regulate the body temperature. Long-term soaking may cause a rapid heart rate and even uncomfortable symptoms such as palpitations and chest tightness. Breathing may become rapid, especially when the user is in an overheated state.

For people with heart problems, staying in a whirlpool spa hot tub for a long time may aggravate the condition or even cause a heart attack. Therefore, people with heart disease should try to avoid soaking in a hot tub for a long time.

4. Heat stroke

In a hot environment, it is difficult for the body to dissipate heat effectively. Especially when soaking in hot water for a long time, it may cause the body temperature to rise above the safe range, causing heat stroke. Symptoms of heat stroke include nausea, dizziness, vomiting, wet skin, shortness of breath, etc., and in severe cases, it may cause loss of consciousness or coma.

Especially in warm seasons or high temperature environments, users should pay special attention to soaking time and avoid staying in the whirlpool spa hot tub for too long.

5. Burns

Although the water temperature of a whirlpool spa hot tub is generally kept within a safe range, hot water may cause skin burns if it is set too high or soaked for a long time. Skin soaking in high temperature water for too long may cause skin redness, swelling, heat, and even blistering, especially in parts that are not sensitive to temperature.

To avoid the risk of burns, users should ensure that the water temperature is moderate and should not exceed 40°C, and check the water temperature regularly to ensure safety.

6. Dizziness and nausea

Exerting hot water for a long time, especially at high temperatures, may cause symptoms such as dizziness and nausea. This is due to changes in blood circulation, which leads to insufficient blood supply to the brain, which in turn affects normal physiological functions. Nausea symptoms will increase physical discomfort and may cause vomiting.

How to use whirlpool spa hot tub safely?

In order to maximize the benefits of whirlpool spa hot tub and avoid potential health risks, users need to follow some usage principles and precautions.

1. Control soaking time

When using whirlpool spa hot tub, it is recommended to control the soaking time within 15 to 30 minutes each time. This not only avoids the burden of excessive soaking on the body, but also maintains the hydrotherapy effect. If necessary, take a short break before re-entering the bathtub.

2. Control water temperature

The water temperature of whirlpool spa hot tub should not exceed 40°C. Too high water temperature will increase the burden on the body, especially for people with a history of heart disease, low blood pressure, diabetes, etc., too high water temperature may bring serious health risks. When soaking, users can test the water temperature with their hands to ensure that the water temperature is appropriate and comfortable.

3. Replenish water

When using the whirlpool spa hot tub, especially when soaking for a long time, users should replenish water in time to prevent dehydration. Staying hydrated helps maintain the body's normal physiological functions and reduces the risk of dehydration and heat stroke.

4. Pay attention to body reactions

While using the whirlpool spa hot tub, if you feel uncomfortable, you should stop using it immediately and leave the tub. In particular, if you experience symptoms such as dizziness, nausea, and overheated skin, you should immediately cool your body, drink water, and rest.

5. Precautions for special groups

For heart patients, pregnant women, and patients with high or low blood pressure, consult a doctor before using the whirlpool spa hot tub to avoid soaking for a long time or using it at high temperatures. High-risk groups should avoid overheated environments, ensure that the water temperature is moderate, and try to shorten the soaking time.
