Is it really that cold inside?

Yes. Dubai's AC systems are powerful. If you are sitting near a vent in a cinema or restaurant, you will feel like you are in an office building in winter.

Should I dress conservatively?

Yes, especially in public spaces. Keeping your shoulders and knees covered with light fabrics serves two purposes: respecting local customs and protecting your skin from direct sun and blasting cold air.

How to handle extreme desert heat and freezing air conditioning

Dress in loose, breathable natural fibers like linen or cotton for the heat, but always carry a dedicated 'AC layer' like a pashmina or lightweight cardigan. The massive temperature swing between 110°F outdoors and 65°F indoors is where most people get sick or uncomfortable.

Master the base layer. Stick to 100% linen or thin cotton. Avoid synthetic fabrics like polyester, which trap sweat against your skin and don't breathe. Loose-fitting shirts and trousers are essential to allow airflow.
Select your AC layer. Carry a pashmina, a light denim jacket, or a merino wool cardigan. It must be something you can put on and take off in seconds. Keep it in your bag; you will need it inside every mall, taxi, and hotel lobby.
Manage your footwear. Wear leather sandals or breathable sneakers. Avoid heavy boots. If visiting religious sites, ensure your footwear is easy to take off and put back on, and always have socks in your bag if you prefer not to walk barefoot on carpet.
Protect your skin from sun and chill. A wide-brimmed hat is non-negotiable for the sun. For the AC, focus on covering your neck and shoulders, as these areas are the first to feel the chill from overhead vent blasts.
