How to warm up or cool down a memory foam mattress?

Yes, so many people experience excellent sleep on memory foam mattresses, even when you have heard about issues with memory foam and heat. The thought of sleeping on a hotbed can seem unpleasant. If you want to learn the truth about memory foam and heat, it will require peeling back the covers, looking at what memory foam is and how it reacts to warmth.

How well a person sleeps can get deeply affected by thermoneutrality, as it is a real problem. For most people temperatures between 60-68 ºF (18-20 ºC) degrees have been known to generate the best sleep. This can be achieved because the body is able to relax and not have to work as hard for auto functions. Plenty of people shiver at temperatures below and may perspire when it gets warm. According to many scientists, it is agreed that a slightly cool circulating temperature results in better sleep, and the problem of keeping cool is necessary for the comfort of many people.

In this article, we are going to discuss the issue of memory foam and how to warm it up or cool it down, either there is validity to the claims or not.

What is Memory Foam?

Originally developed by NASA, memory foam was used for shuttle seats to reduce impact during cosmic acceleration. Since that time of period, it has been used in plenty of things such as- exercise machines, medical equipment, and bedding. It is utilized in absorbing and distributing body weight evenly in a mattress.

This foam is made of viscoelastic polyurethane, an absorbent and soft foam material. It has the capacity to form to the body, by producing a “hug” sensation. The encircling feature it has relieves pressure points and eliminates pain. Yet, this same contouring specification also absorbs heat, which causes many to wake up during the night.

Types of memory foam

There are actually four different types of foam instead of one type, they are all similar, but each of them generates different properties. Traditional, air cooling, gel, and plant-based foams are included in these kinds. If you know the differences and similarities, it can easily drive you in the direction of the concrete purchase.

Traditional memory foam

These mattresses first came in the ’90s. It gained popularity very quickly due to its unique features, the memory foam mattress stimulated expanded blood flow, pressure point relief, and flawless support. Furthermore, it has hypoallergenic characteristics, as there is little to no risk of dust mites and other bugs. Those who are constantly suffering from allergies, it is a great relief. Despite the fact, the overheating condition of traditional memory foam still remains a drawback.

Gel memory foam

Just like traditional, gel memory foam has the same features, such as body contouring pressure relief, antimicrobial properties, and motion isolation. If you concentrate while researching you will notice the differences. For example, the infusion of gel beads absorbs body heat and has good endurance.

Nonetheless, sometimes an issue can arise in the amount of heat the gel beads can absorb before the body begins to preserve heat. Plenty of consumers have experienced overheating with gel memory foam beds while sleeping, especially hot sleepers..

Air cooling memory foam

After the traditional memory foam mattresses were released, manufacturers got to know about the public’s negative reactions and attempted to amend the issue by designing cool memory foam technology. The open-cell structure lets air to pass through the bed, and hence advance overall cooling. As the surface itself still retains some heat, it was somewhat more convenient than traditional foam.

Plant-based memory foam

One of the most neglected kinds of foam is plant-based. Compared to the other four, this one is the most breathable. It’s eco-friendly substantial is free from preservatives, like formaldehyde, benzene, and naphthalene, traditionally found in other foams. With Castor oil, the plant-based foam takes over part of the petrochemicals and is known to expend heat faster than traditional memory foam.

If you are sleeping on memory foam and you are feeling cold every night, there are few ways by which you can change your sleeping condition.

Did you now?

You have to be very careful when some dirt or stain sticks on your mattress and you are about to clean it up. The proper ingredients with a suitable method are obligatory. To avoid any damage, check out our guide on how to wash memory foam.


How to warm up a memory foam mattress?

If you turn up the thermostat to warm up just the bedroom is inefficient and will only increase your energy bills further up. A better decision is to just heat up your bedroom or even more specifically, just the mattress. Here are a few ways to warm up a memory foam mattress.

Use a heated mattress topper or pad

You have to be extra careful if you are using a memory foam bed in a box mattress as they tend to give more reaction to heat than other types of mattresses.

To warm up your bed you can use a heating pad consists of a network of wires inside. Current will go through the wires and they heat up when you turn the heat on. This in change will warm up the pad and the memory foam surface you are sleeping on. You have to use an attached controller so that you can manage the temperature of your bed as you want.

These days most heating pads also contain timer controls that automatically switch off the heat after a specific period of time, and few heated mattress pads have dual controls that let you set a variety of temperatures for each side of your bed. They are a great option for couples who generally have different sleeping preferences.

Don’t forget that to protect your memory foam you have to use the lowest setting on your heating pad to avoid any kind of damage.

Electric blanket

Just like a heating pad, if you use an electric blanket, it will work the same way. In fact, in some places ‘heating pad’ and ‘electric blanket’ is used correspondently with heating pads sometimes referred to as under blankets. The major difference you will notice between an electric blanket and a heating pad is that the former goes on top of your body. These blankets come with similar controls as heating pads, such as- temperature control, timer and dual controls.

Again, just like before, to protect your memory foam mattress, use the lowest setting on your electric blanket too.

Flannel winter bed sheets

In winter flannel is a great option of material for bedsheets to warm up your memory foam as it is cotton that’s been brushed to make it fluffy, rather than unwrinkled like normal cotton sheets. Adding all that extra fluffiness will mean more air is trapped inside your bed, which will make it a better insulator.

Use layers of top sheets and blankets

Rather than just having one thick blanket, comforter or duvet, you can create layers instead to warm up your mattress. The idea behind this is to create layers of insulation and trap air which may seem like poor conduct but it works. If you get too warm in the night these layers will also work well as you can just remove them. You can try to alternate between thinner and thicker layers to maximize the insulation effect.

A warmer comforter or duvet filling

If you face no big issue while using animal products, the heated filling for comforters and duvets is down and/or feathers. Wool is another effective filler, which will also trap air very efficiently, while it will be more breathable than synthetic fillings. If you prefer to avoid animal-based fillings, a good choice of warm material is a hollow fiber.

Climate control system

The system works by directing warm air into the memory foam mattress under the sheets. Another thing you can do is to try to plug it into a comforter with cavities where the system pumps in warm air. A climate control system will provide you most of the same features and will control just like a heated pad or electric blanket.

You can decide to have a dual set up for you and your partner, by which you can control how warm your mattress gets and you can also set a timer. As we know the memory foam or the Viscoelastic foam absorbs heat quickly, so use the lowest setting, while using the climate control system for avoiding any sort of damage.

Hot water bottle

If you prefer something cheap to warm up your bed at night, then a hot water bottle is a great option. It is also perfect if its only your feet that get cold and need warming. But if you want your whole body to get warm, I will recommend any of the above methods. Those are much better and more effective than a hot water bottle.

Space heater

If you cannot warm up your memory foam, the next best option is to warm your bedroom. The best way to do this is if you use a space heater. One of the best advantages is its adaptability. You can just pick it up and use it in the living room or your home office in the morning, which you won’t be able to do with a heating pad.

As we are talking about warming up the memory foam mattress so as to make sure the bed is at the perfect temperature when you sleep, preheat it for around 30 minutes before bed, then you can turn it off and let the trapped heat keep you warm through the night.

Did you know?

Changing your sleep position is tricky, but not impossible at all. Pillows, a sofa, and some other things might be very useful. The healthiest is side sleeping; you will never wake up with pain in your back! Read on for complete information.


How to make a memory foam mattress cooler?

Buying a new mattress can be expensive and also it cannot be your only solution, and if you love your current one there are few ways to help you sleep cool. You can use these following methods now to help lessen the temperature and achieve a deeper, restful sleep.

Switch out your bedding

Something like a simple change of bedding can help to improve circulation. You can lean towards those materials that are made of natural fibers like cotton or bamboo which will provide better airflow and wick away moisture. Also, you should stick to a lower thread count. Our recommendation would be a thread count of 300 or less for cotton material.

Bedsheets

You can choose a bed sheet of low thread count, made from Tencel, cotton, or linen can make all the difference in temperature at night. Also, find out what type of material is inside your comforter or duvet. Using cotton or down alternative fill for optimal cooling is a good solution.

Mattress pad

The pad adds a layer of space for airflow and better cooling, and also will generate an extra level of comfort. A gel memory foam mattress topper is a highly recommended option from us.

Pillows

You can look for cooler materials like cotton, bamboo, feathers, and polyester. Sometimes pillows will offer you cooling properties, like gel memory foam or copper infusions.

Wear breathable clothes while sleeping

If you change your pajamas to a breathable material it might help extremely along with the change of bedding. Not only the breathable material will cover your bed matter, the kind of material that covers your body can also affect your body temperature. For example, you can choose cotton, wool, silk, linen, etc.

Change the bedframe

It is true that memory foam mattresses do best with a solid foundation, and additional cooling can be accomplished by switching to a bed frame with equally spaced slats. This will give more airflow underneath the bed. You should check details about the product manufacturer for recommendations.

Get constant airflow for your bedroom

A consistent airflow and better air circulation will help to reduce the buildup heat. There are plenty of methods you can choose to achieve this:

  • turn on your ac at night while sleeping,
  • you can open your bedroom windows to get fresh air,
  • or you can turn on your fan to circulate air.

If you don’t own a working A/C, you can just place a bowl of ice in front of a portable fan. It will work like a charm too.

Turn off the lights

Lights discharge heat, and as heat accumulates over time, so if you turn off all light sources it will keep the room cool and ensure a deeper sleep.

Stay hydrated before sleeping

Drinking plenty of water can help your body get cool down at night. It might also be a good idea to put a glass of cool water next to your bed if by any chance you wake up hot in the middle of the night.

Conclusion

To sum up, if your memory foam is making you hot at night and you want to have a good experience of sleeping, then you should try changing your bedding, put breathable clothes on or get constant airflow in your bedroom.

On the contrary, when the cold mattress is a problem, buying a heated mattress topper or pad, using layers of sheets or simply a bottle of hot water might be a great solution. You should try a few of these methods to see which one works the best.
