The Hidden Risks of Air Conditioning
1. Extremely Low Indoor Temperatures
Keeping the air conditioner set too cold for extended periods can overstimulate the body’s sympathetic nerves. This stimulation triggers the release of adrenaline, which elevates blood glucose levels — potentially leading to hyperglycemia in sensitive individuals.
2. Reduced Physical Activity and Energy Loss
Summer heat typically causes the body to sweat, helping regulate internal temperature and burn energy. However, if you stay in an air-conditioned room all day without sweating or moving much, your body uses less energy. This drop in energy consumption can contribute to higher blood sugar levels.
3. Poor Ventilation and Low Temperatures Can Weaken Immunity
Prolonged exposure to cold air, especially in poorly ventilated, sealed rooms, creates an environment where bacteria and viruses can thrive. For those with diabetes — whose immune systems are often already compromised — this can increase susceptibility to respiratory infections, arthritis flare-ups, gastrointestinal issues, and even cardiovascular or cerebrovascular problems. These secondary illnesses can indirectly disrupt blood sugar regulation.
Smart Guidelines for Using Air Conditioning Safely
To enjoy the comfort of air conditioning without risking your health, especially if you have diabetes, keep these key points in mind:
1. Keep the Temperature Moderate
Set the AC to around 26°C (about 78.8°F). The indoor temperature should not differ from the outside by more than 8 degrees Celsius, to avoid shocking the body and disrupting its regulatory systems.
2. Limit Time in Cold Rooms
Try not to stay in an air-conditioned room all day. Spend time outdoors in the early morning or evening when it’s cooler, to get fresh air and stay active. Indoors, consider using fans or natural ventilation during cooler parts of the day to reduce reliance on air conditioning.
3. Avoid Running the AC Overnight
Instead of keeping the air conditioner on all night, cool the room for a while before bedtime, then set a timer to shut it off automatically. Use a fan during the night to maintain air circulation — but avoid letting it blow directly on your body.
You can also program the AC to operate intermittently during the day, and regularly open windows to refresh the air and improve circulation.
Additional Tips
-
Never let cold air blow directly on your body. Adjust the vent direction upwards so the cool air descends gently into the room.
-
Stay alert to how your body reacts. If you begin feeling discomfort, fatigue, or symptoms of respiratory or joint issues, reassess your exposure to cold air.
By following these precautions, you can safely enjoy the benefits of air conditioning while protecting your health during the hot summer months — especially if you have diabetes or are managing other chronic conditions.
