Introduction
Foot odor resembling the smell of cooked rice may be caused by factors such as hot weather, poorly ventilated shoes, hyperhidrosis (excessive sweating), athlete's foot (tinea pedis), or eczema. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a healthcare professional. In daily life, it is advisable to develop good hygiene habits, maintain proper foot cleanliness, change and wash socks frequently, regularly clean and air out shoes, and keep feet well-ventilated and dry.

Generally, a foot odor resembling the smell of cooked rice may be caused by hot weather, poorly ventilated shoes, hyperhidrosis (excessive sweating), athlete's foot (tinea pedis), or eczema. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a healthcare professional. Specific analysis is as follows:

1. Hot Weather

In hot weather, body heat increases and sweating becomes more likely. If feet are not washed promptly, sweat can ferment and lead to an odor similar to that of cooked rice. Maintain good hygiene by washing feet regularly, changing socks frequently, and keeping the feet clean.

2. Poorly Ventilated Shoes

Wearing low-quality shoes with poor breathability creates a warm, moist environment inside the shoe, which promotes bacterial growth. Bacteria breaking down dirt and sweat can produce a cooked rice-like odor. Regularly clean shoes and opt for footwear with better ventilation.

3. Hyperhidrosis (Excessive Sweating)

Conditions such as emotional stress, intense physical activity, or hormonal imbalances may lead to hyperhidrosis, causing persistently sweaty feet. This damp environment can foster the growth of bacteria and fungi, potentially resulting in a cooked rice-like smell. Under medical supervision, treatments such as aluminum chloride solution, aluminum acetate solution, or alum solution may be used. However, care should be taken with frequency and dosage to avoid excessive skin dryness or cracking.

4. Athlete’s Foot (Tinea Pedis)

Fungal infection causing athlete’s foot may lead to symptoms such as blisters, peeling skin, or whitish, soggy skin. It may also result in a foot odor resembling cooked rice. With guidance from a doctor, antifungal medications such as amorolfine hydrochloride cream, luliconazole cream, or itraconazole capsules may be used for treatment.

5. Eczema

Bacterial infections associated with eczema may cause symptoms including itching, skin breakdown, and pus discharge on the feet, which could contribute to a cooked rice-like odor. Under medical supervision, topical antibacterial treatments such as compound acetic acid dexamethasone cream, halometasone cream, or hydrocortisone butyrate cream may be applied.

It is advisable to develop good hygiene habits: maintain proper foot cleanliness, change and wash socks regularly, clean and air out shoes frequently, and keep feet dry and well-ventilated to help alleviate symptoms.
