Introduction

It is recommended to wait about 1 to 2 hours after exercise before taking a cold shower. After physical activity, blood circulation and metabolism increase, causing a redistribution of blood flow—more blood flows to the waist, abdomen, and limbs, while blood supply to vital organs such as the heart and brain decreases. Therefore, taking a cold shower immediately afterward may cause certain physiological stress to the body.

After exercising, blood circulation and metabolism in the body increase significantly. Blood is redistributed throughout the body, with most flowing to the waist, abdomen, and limbs, while blood supply to vital organs such as the heart and brain decreases. Taking a cold shower at this time may excessively stimulate the body, causing abnormal constriction of blood vessels. This can lead to insufficient blood perfusion in the brain and heart, resulting in obvious ischemia and hypoxia, which may trigger adverse symptoms such as dizziness, headache, and general weakness. Additionally, after exercise, pores all over the skin are open. If exposed to cold water at this point, the body is more susceptible to cold invasion, allowing cold pathogens to enter and potentially cause muscle pain or even catch a cold. Therefore, it's not advisable to take a cold shower immediately after exercise. Instead, allow adequate rest and wait 1 to 2 hours before showering.

For individuals who do not have particularly strong physical health, regular cold showers are not recommended in daily life, as they may lead to bodily harm.

Can eczema be completely cured through long-term running?

In general, long-term running cannot cure eczema completely. However, moderate running combined with proper skincare can positively improve symptoms. Increased sweating during running may irritate the skin if not cleaned promptly, as salts and metabolic byproducts in sweat can be irritating. Therefore, it's important to clean the skin immediately after exercise and apply a moisturizer. Clothing should be made of breathable, sweat-absorbing materials to minimize skin irritation from friction.
