Georgia’s National Center for Disease Control and Public Health issued fresh precautions on August 3 as hot weather settled over the country, warning that high temperatures bring serious health risks that climate change is making more frequent and prolonged.
The agency’s list covers hydration, shade, clothing and a blunt ban on leaving children or animals in parked cars. Behind the tips sits a larger pattern: longer heat spells now worsen chronic illnesses and raise infection risks as a standing public-health load.
What the NCDC Told Residents to Do
The core advice is simple and immediate. Avoid the outdoors in the hottest hours. Drink water steadily. Skip alcohol, sugary drinks and caffeine. Move any hard physical work to the cooler morning.
Parents and pet owners received the strongest line: never leave children or animals inside parked vehicles. Interior temperatures climb to life-threatening levels fast. Outdoors, wear light-colored, loose clothing made from natural fabrics, plus a hat and sunglasses. Use an umbrella for shade. Keep homes cooler by ventilating in the early morning and at night.
- Stay hydrated with water; avoid alcohol, sugar and caffeine
- Limit outdoor time and strenuous activity to cooler morning hours
- Never leave children or pets in parked cars
- Choose light loose natural-fabric clothing, hats and sunglasses
- Ventilate homes early and late; keep rooms as cool as possible
Parallel coverage from local outlets added food and water rules that rise with the heat. Store food properly, cook it thoroughly, keep raw and cooked items separate, and never leave cooked food at room temperature more than two hours. Wash produce under running water. Boil drinking water if quality is uncertain. Wash hands with soap before food prep and eating.
Longer Heat Spells Are Already Here
NCDC stated that heatwaves remain a major public-health challenge. Against the backdrop of climate change, extreme heat episodes are becoming more frequent and prolonged in Georgia. That raises heat-related illness risk and worsens chronic non-communicable diseases.
World Bank climate risk data put numbers on the shift. Average temperatures have risen 0.3°C in western Georgia and 0.4-0.5°C in eastern areas since the 1960s. In Tbilisi the number of days when the heat index reached dangerous levels increased by 14 between the 1986-2010 period and the 1961-1985 baseline. The capital also faces a clear urban heat island effect that makes residents more vulnerable as extreme temperatures grow more common.
| Indicator | Observed or Projected Change |
|---|---|
| Western Georgia temperature since 1960s | +0.3°C |
| Eastern Georgia temperature since 1960s | +0.4-0.5°C |
| Tbilisi dangerous heat-index days | +14 (1986-2010 vs 1961-1985) |
| Heat-wave frequency by 2090s (higher emissions) | Sharp rise; up to 1-in-5 annual chance under RCP8.5 |
| Projected temperature rise by 2090s | 1.4°C to 4.9°C above 1986-2005 baseline |
Recent forecasts for Tbilisi showed afternoon highs near 34-35°C (93-95°F) in early August, well above the long-term August average near 29-31°C. The pattern matches the agency’s description of more frequent and extended episodes rather than a one-off heat spike.
The Parked Car Turns Deadly Fast
The NCDC’s strongest warning targets parents and pet owners. Cars become ovens. Even on a mild day the interior can climb almost 20 degrees Fahrenheit in the first ten minutes, and a cracked window does little. A child’s body temperature rises three to five times faster than an adult’s. Hyperthermia can kill in minutes.
Key vehicle risks:
- 20°F rise possible inside a car within 10 minutes
- Child body heat climbs 3-5 times faster than an adult’s
- Average 38 U.S. childhood vehicular heatstroke deaths per year in long-term data; 31 recorded in 2025
- Never safe for toddlers, disabled people or pets, any season
U.S. National Weather Service guidance is blunt: it is never safe to leave a toddler or pet locked in a car. The same physics apply in Tbilisi traffic or supermarket lots. CDC heat-health pages note that temperatures inside a car can rise almost 20 degrees Fahrenheit quickly even with a window cracked. Local residents already treat summer heat as a conversational baseline; the advisory simply makes the lethal edge explicit.
Chronic Illnesses Take the Heavier Hit
Heat does more than cause heat exhaustion or heat stroke. It exacerbates heart disease, respiratory conditions, diabetes and other non-communicable diseases. Longer episodes mean more days when older adults, people with pre-existing conditions and those without reliable cooling face elevated risk. NCDC flags exactly this compounding effect.
Urban density in Tbilisi amplifies the load through the heat-island effect. Nighttime temperatures stay higher, giving bodies less recovery time. Outdoor workers, market vendors and construction crews absorb the cumulative stress. The second-order cost shows up in hospital visits, medication adjustments and lost work days rather than only in the dramatic collapse stories.
Food and Water Safety Tighten in the Heat
High temperatures speed bacterial growth. The risk of intestinal infections and food poisoning climbs. NCDC-linked advice stresses basic barriers: keep raw and prepared foods separate, cook thoroughly, refrigerate promptly, and discard anything left out more than two hours. Wash fruits, vegetables and herbs under running water. Treat questionable drinking water by boiling. Handwashing with soap before cooking and eating remains one of the strongest defenses.
These steps are ordinary in cooler weather. In prolonged heat they become daily non-negotiables. Tourists and residents alike face the same rules when picnic food or market produce sits in the sun.
Daily Rhythm Shifts Toward Cooler Hours
The practical response is behavioral. Move errands and exercise to early morning or evening. Seek air-conditioned spaces or deep shade during peak sun. Light natural fabrics and wide-brim hats cut radiant load. Umbrellas double as portable shade in open squares. At home, close blinds against the afternoon sun and open windows when outside air cools.
National national heat health information resources and local forecasts help people plan. Georgia’s own data show the trend is not reversing soon. Under higher-emissions pathways the annual chance of a heat wave could reach one in five by the 2090s, according to the Tbilisi dangerous heat-index days rose by 14 analysis and related projections. The current advisory is therefore both immediate protection and a preview of summers ahead.
Residents who treat the list as routine summer hygiene will cut the acute risks. The deeper task is adapting homes, work schedules and health systems to heat that no longer feels exceptional.
