Seal drafts around windows and doors

Use weatherstripping, draft stoppers (or rolled towels) under doors to block cold air leaks.

Use thermal or heavy curtains

Hang thick, lined curtains and keep them closed at night or on cold days to trap heat inside.

Add rugs or carpets on bare floors

Bare tiles or wooden floors let heat escape; rugs act as insulation and make feet feel warmer instantly.

Reverse your ceiling fan direction

Switch the fan to clockwise (winter mode) on low speed to push warm air down from the ceiling.

Let sunlight in during the day

Open curtains on south-facing windows when the sun is out to allow free solar heating, then close them before sunset.

Use hot water bottles or DIY rice socks

Fill a hot water bottle or heat a sock filled with rice in the microwave for instant, portable warmth in bed or on the couch.

Layer rugs or add blankets on furniture

Double up rugs or throw thick blankets on sofas and beds to create cozy, insulated spots.

Bake or cook more often

Using your oven or stove releases heat into the kitchen and surrounding rooms; leave the oven door open after baking (safely) to let heat escape.
