Some time ago, a video of actress Alia Bhatt washing her face with ice-cold water went viral, sparking intensified discussions on the subject. Prior to this, actresses like Ananya Panday and Katrina Kaif had also shared videos recommending the practice of submerging one's face in cold water.

According to them, cold water is highly beneficial for the face. It helps reduce facial puffiness, tighten the skin, and maintain a natural glow. It improves blood circulation by constricting the blood vessels in the face. Moreover, washing your face with cold water also instills a sense of mental calm and tranquility.

**Cold Water Prevents a Sticky Sensation**
During the summer season, washing one's face with cold water or ice is a simple yet effective home remedy. As soon as the face is washed with cold water, the skin's temperature begins to drop, restoring a sense of freshness. In fact, the skin tends to produce more sweat and oil during the summer, which can exacerbate issues such as stickiness and acne. Cold water temporarily soothes these glands and helps regulate excess oil production.

**The Scientific Rationale**
From a scientific perspective, the impact of cold water on the skin is primarily attributed to *vasoconstriction*. Upon exposure to cold, the skin's blood vessels constrict; this process helps alleviate swelling, redness, and irritation. The process wherein the muscles of the blood vessels contract—thereby reducing their diameter—is known as *vasoconstriction*. This mechanism regulates the body's temperature by reducing blood flow. It is a natural and vital physiological process within the body.

**Beneficial for Specific Skin Concerns**
Common summer-related skin issues—such as sunburns, heat rashes, enlarged pores, and oily skin—can be significantly mitigated through the use of cold water or ice. Ice is particularly effective in reducing puffiness under the eyes and combating facial fatigue.

**Precautions**
Applying ice directly to the skin can lead to complications such as frostbite; therefore, it should always be applied by wrapping it in a soft cloth or using an ice roller.

Washing your face with cold water two to three times a day is sufficient. Excessive washing can disrupt the skin's natural moisture balance.

Cold water should be used for only one to two minutes.

Individuals with highly sensitive skin or those suffering from rosacea should use ice with extreme caution.
