How to Warm a Room

Use windows and drapes to warm the room with sunlight. One of the easiest ways to make a room warmer is to take advantage of the sun, mother nature’s original source of heat. In general, during the day you should let the warm sunlight shine into the room as much as possible, and at night you should prevent heat loss. For optimal results, you also need to know which windows in the room get sunlight. Generally, sunny windows are south-facing windows if in the northern hemisphere, and north-facing windows if in the southern hemisphere. ^[1] Here is a simple sequence you can do:

• Morning: Before going to work or school, close all room windows. Open all the windows.
• Afternoon: Leave the curtains open until the sun no longer shines into the room. Close the curtains as soon as it starts to get dark and cold.
• Night: Close windows and drapes throughout the night to keep the heat in the room.

Wear layers of warm clothing that don’t consume energy. In this day and age, when climate change caused by human lifestyle is becoming a big concern, many environmentally concerned consumers choose to keep warm, not room heating. Wearing a jacket, sweater, or sweatpants indoors is a great way to stay warm without spending a single bit of heating energy (or paying a dime to pay your heating bill.)

• If it’s freezing cold in the bedroom at night, try wearing layers of clothing. Although some people find it uncomfortable to wear thick clothing, soft materials like gym pants and sweatshirts will often keep you warm without causing discomfort.
• Man-made materials that don’t “breathe” like ppyester, rayon, and the like usually hold heat very well (which is why they’re so uncomfortable in the summer.)

Put the hot water bottle on the bed. One of the worst feelings in the world is walking around in your pajamas in a cold room, and then when you go to bed, the bed is as cold as ice. Although the bed will warm up once you’ve been in bed for a while, you can avoid shivering by warming the bed before bed. A hot water bottle would be a great way to do this; You just need to pour very hot water into the bottle, close the lid tightly and place it under the blanket in the middle of the bed 15 minutes before going to bed. When the water bottle cools, it radiates heat around and gives you a warm and comfortable feeling when lying in.

• Medical hot water packs are available at drugstores or online for more than one hundred thousand to several hundred thousand dong.
• If you’re using a microwave to boil water, be sure to use a microwave-safe container (like a glass or ceramic bowl).

Use blankets to seal the gaps. When you’re trying to keep a room warm, the most annoying thing is the openings, where cold air can get into the room. You can use a rag or blanket to seal the gaps while you wait for a more permanent solution (like replacing a cracked window, etc.). When openings let the wind in, this simple response can make a big difference.

• Not sure if there is a gap in the room? There are many ways for you to find out. A simple way is to put your hand near the slits in a window or door and feel the air move. You can also experiment with candles – if the flame flickers when you bring it closer to the slits, there’s air in.

Use available heaters or fireplaces as efficiently as possible. There is a heater or heater in the room, but how much does the room warm up? Follow the tips below to increase fireplace efficiency (and save money, too):

• Make sure there is no furniture blocking the front of the heater. For example, many traditional homes often have a fireplace behind the sofa.
• Stick tin foil behind the fireplace (use a sheet of tin foil about the same size as the fireplace). The tin foil will reflect heat that would normally be transferred to the wall, helping to warm the rest of the room.
• If it is a portable heater, you should use it in the smallest possible space to get the most out of the heater’s performance. For example, a portable heater in a small bedroom will keep you warmer than in a large living room.

Invite guests to the house to play. We often forget that humans have an inherent need to walk, talk, and are also natural “fireplaces” that continuously radiate heat into the surrounding air. If there were an extra guest or two sitting in the room, it would make a difference – the heat of the human body and the heat in the exhaled air would help warm the room.

• There are two things you need to remember when choosing this option: the smaller the room and the more active people are, the warmer it will be. In other words, a boisterous party in a small room will generate more heat than several people sitting on a sofa in a large living room.
• If you can’t bring friends over because everyone’s busy, pets can help keep you warm (unless they’re cold-blooded—fish or lizards won’t help).

Use a hair dryer to blow on the bed. This tip may seem a bit weird, but it really works. In essence, a hair dryer is like a tiny heater with a fan inside. You can blow hot air directly on the bed or lift the blanket and point the hair dryer head into the blanket to create a warm air pocket before lying in it.

• Be careful not to let the metal parts of the hair dryer head touch the bedding, especially if it’s a flowable material (like ppyester or similar.)
