Hong Kong summers are notoriously intense, with high humidity and soaring temperatures frequently triggering “Very Hot Weather” warnings. For a domestic helper managing physical tasks—whether it’s grocery shopping at the wet market, walking the dog, or cleaning windows—the risk of heat exhaustion is a serious health concern.
As an employer, we recommend sharing these tips to help your domestic helper stay safe against heat exhaustion during Hong Kong’s summer season.
Understanding Heat Stress and Warning Signs
Heat exhaustion occurs when the body overheats and cannot cool itself down. If left untreated, it can progress to heat stroke, which is a life-threatening emergency.
Watch for these symptoms in your helper:
-
Dizziness, headache, or confusion.
-
Excessive sweating and pale, clammy skin.
-
Rapid pulse and muscle cramps.
-
Nausea or vomiting.
-
Extreme fatigue or weakness.
Practical Prevention Strategies for the Home
As an employer, small adjustments to the daily routine can significantly reduce the risk of heat stress.
-
Reschedule Heavy Tasks: Encourage your helper to do strenuous outdoor chores—like car washing or grocery shopping—early in the morning (before 10 AM) or later in the evening when the sun is less intense.
-
Improve Ventilation: Ensure the kitchen and laundry areas are well-ventilated. If your helper is working in a room for an extended period, allow the use of a fan or air conditioning during extreme heat.
-
The “Hydration Station”: Make it clear that your helper should take frequent water breaks. Remind them that they don’t need to wait until they are thirsty to drink.
-
Appropriate Workwear: Suggest light-colored, breathable cotton clothing for outdoor tasks, and ensure they have access to a hat and umbrella for sun protection.
Following the “Heat Stress at Work” Warning System
In 2023, Hong Kong introduced the Heat Stress at Work Warning (Amber, Red, and Black). While primarily designed for outdoor laborers, these guidelines offer a professional framework for households:
-
Amber Warning: Increase rest breaks and ensure water is readily available.
-
Red Warning: Suspend heavy physical tasks (like deep cleaning or heavy lifting) during the warning period.
-
Black Warning: All strenuous physical work should stop until the warning is lowered.

Emergency Protocol: What to Do
If you suspect your domestic helper is suffering from heat exhaustion:
-
Move them to a cool place: Get them out of the sun and into an air-conditioned or shaded area.
-
Cool the skin: Use wet towels or a cool mist spray.
-
Hydrate: Give them water or an electrolyte drink if they are conscious.
-
Seek Medical Help: If symptoms do not improve within 30 minutes, or if they lose consciousness, call 999 immediately.
Remember, prevention is always better than treatment. It’s essential to educate your domestic helper about the symptoms of heat exhaustion, encourage them to take preventive measures, and provide a safe and comfortable working environment during hot weather. Regularly check in on their well-being and ensure they have access to shade, hydration, and cooling measures to reduce the risk of heat-related illnesses.
Domestic Helper Contract And Visa Renewal
As an employer, please note that you need to renew your helper’s contract and visa every two years. If you would like to save time and trouble going to the Immigration Department and POLO, you may contact the HelperChoice team to process your helper visa application for you.
