What are the advantages of cold showers?

Mental Health

A clinical study found that individuals who take cold showers into their daily routine for a few months experienced a decrease in depression symptoms. Subsequent studies have indicated that cold water has the potential to enhance mood and decrease anxiety. 

Endorphins can be triggered by cold water, and these endorphins are able to decrease feelings of stress and anxiety. A study discovered that taking short, cold showers twice a day led to a decrease in depressive symptoms. However, it is important to note that the participants in the study did not have a clinical diagnosis of depression, but merely reported having feelings of depression.

Furthermore, cold showers have the potential to enhance alertness and concentration by increasing cortisol levels. Cortisol is a hormone released by the body in response to stress, and it plays a crucial role in regulating various bodily functions such as blood sugar levels, metabolism, and immune response. Cold showers can boost cortisol levels by activating the sympathetic nervous system, which is responsible for the body's "fight or flight" response. This response can elevate heart rate, blood pressure, and cortisol levels, all of which contribute to improved alertness and focus. 

Skin Care

The benefits of cold showers extend to both your skin and hair. Unlike hot water, cold water helps retain the natural oils that keep your hair and skin well-moisturized and healthy.

Moreover, cold water enhances the look of your hair, making it appear shinier and less unruly. By sealing the hair cuticle, cold water prevents moisture loss and damage.

Furthermore, cold water has a tightening effect on the skin, reducing the visibility of pores and giving it a smoother and more even complexion. It also aids in reducing inflammation and puffiness, which can be especially advantageous for those with sensitive or acne-prone skin. 

Internal Body Improvement

Claims made by influencers in support of cold water therapy often focus on the potential for increased weight loss by boosting calorie-burning capacity. While further research is required to confirm this, some studies suggest that immersion in cold water can accelerate metabolic rate, which refers to the rate at which the body uses energy and burns calories.

The process of cold water therapy can stimulate metabolism by requiring the body to exert extra effort in maintaining its core temperature. This increased activity leads to higher energy expenditure. 

Additionally, exposure to cold water puts strain on the body, triggering a "survival mode" response where the body works harder to regulate its core temperature. This response prompts an increase in blood flow circulation, further contributing to the stimulation of the metabolism. 

What are the disadvantages of cold shower?

Taking cold showers causes the blood vessels to constrict, leading to increased blood pressure and heart rate. This can be problematic for individuals with heart conditions, potentially causing irregular heartbeats or fluid accumulation in the lungs. Therefore, those with heart or lung issues should avoid cold showers unless they have consulted a doctor.

Furthermore, if you are already unwell with a cold, cough, or fever, cold showers may make you feel worse. They can negatively impact your immune system, making you feel colder and take longer to warm up.

If the idea of a cold shower is too intense for you, experts recommend starting with a warm temperature and gradually lowering it to a cool level as you finish bathing. 
Despite the challenges, there is scientific evidence supporting the benefits of cold showers, making them worth considering for those willing to brave the cold water. 

What are the advantages of hot showers?

If you struggle to relax or fall asleep at night, you may find yourself tempted to take a hot shower in order to reduce the stress of the day. This is a common method for relaxing muscles before bedtime, as hot showers activate the parasympathetic nervous system and make us tired. Additionally, hot showers have various other benefits, 
such as providing relief from respiratory symptoms, helping with blemishes, and aiding in muscle relaxation. 

By taking night-time showers into your routine, you can enhance sleep quality and alleviate stress.

What are the disadvantages of hot shower?

The heat from the shower opens up the pores of the skin, allowing trapped dirt and oil to be cleaned out. Being immersed in hot water effectively eases body tension and can soothe muscle fatigue. 

Although there are some downsides to hot showers, the good news is that you don't have to completely forgo them. By simply lowering the temperature a bit and taking care of your skin afterward, you can still enjoy their benefits. 

It's important not to substitute hot baths and showers for exercise. It's also crucial to be mindful of the temperature and not stay in the tub for too long, as this can increase the risk of burns or heat stroke. Limiting your bath or shower time to around 20 minutes and avoiding extremely hot or cold water is recommended.
