🧠 Main Reasons Your Room Gets So Hot
☀️ 1. Direct Sunlight
Rooms that face the sun — especially south-facing — absorb heat all day.
- Sunlight heats walls, floors, and furniture
- Heat builds up over hours
- The room stays hot even after sunset
👉 This is one of the biggest causes in UK homes.

🧱 2. Heat Trapped in Walls and Furniture
Materials like brick, concrete, and even wood:
- Absorb heat during the day
- Slowly release it at night
👉 This is why your room can feel hotter at night than outside.

If air isn’t moving:
- Heat gets trapped
- Fresh air doesn’t circulate
- The room feels heavy and stuffy
👉 Small flats and bedrooms are especially affected.

- Gaming consoles
…all produce heat.
👉 In small rooms, this builds up quickly.
🏢 5. Top Floor or Loft Rooms
If you live:
- On the top floor
- In a converted loft
👉 Heat rises — and gets trapped above you.
