At Unbox Mattress, we’re obsessed with getting the best night’s sleep. And while there are many, many reasons you’re not getting the best sleep you can, your bedding is a part of that.
If your room is too hot, your body will struggle to keep your body temperature at a comfortable level. Too cold, and you can’t sleep well. The climate or time of the year (hello, summer) you live in can be a factor. Night sweats, hormonal changes, and even aging can throw off your body temperature.
It’s a challenge to find the right temperature for the best sleep. Here are some ways we’ve found to help.
Sleep Issue: You Sleep Too Hot
Problem: You get hot and sweaty at night (and it’s not from sex).
Sleeping too hot is one of the most common sleep issues. According to a survey by Sleeprate, 80% of people said they slept better during cooler months compared to summer months. And this sleep study says sleep is actually disturbed more by too much heat than by being too cold.
Solution #1: get a new mattress. If you normally don’t sleep hot, it could be your mattress. Memory foam heats up, softens up, sinks, and traps body heat then cooks you all night long.
All foam mattresses with large sheets of foam stacked on each other don’t allow for airflow, which means you sleep hotter. Here’s the mattress we recommend if you sleep hot. This recommendation is based on tests by Consumer Reports on cooling beds and our own experience.
Solution #2: If you sleep hot because you tend to be sweatier or you’re going through hot flashes (menopausal women), it may be more than your mattress. In that case, we recommend a bed fan or cooler. Products like a BedJet or Chilipad can cool you down fast – for a price.
The BedJet is a bed fan that recirculates cooler air on the ground or warms the air. Turn it on, and you get cool within seconds.
The Chilipad is not a fan, rather it's a mattress pad that circulates water through a network of tiny tubes. It has a temperature range between 55°- 110° F, which covers just about anyone who sleeps hot. Sleep in a hot climate? Try using a Chilipad to cool down to 55°!
These products work well, but they're also more pricey. The next solution is less expensive (but may take longer to work or not work as well).
Solution #3: Cooler blankets and bedding.
To stay cool, you need a blanket that allows good airflow in and out of your sleep space. Trapped air heats up quickly, which raises your body temperature. Look for a blanket with natural or synthetic venting structures.
Blanket materials with good breathability include Regular cotton, Egyptian cotton, Linen, Satin, Viscose, and Rayon Blends (e.g., cotton & linen). We love linen for the summer or just for cooling. Just be aware that even though it's not the softest option, it softens up as you wash it.
Another thing that keeps you too hot is sweating. When you have wind to cool you off, that's not a bad thing. When it makes your bedding moist, it is.
A cooling blanket should be made of fabric with good absorption properties or hygroscopy. It will then “wick” or draw moisture from the air instead of trapping it next to you.
Here are some blankets with good absorbency: cotton, hemp, bamboo, flax linen, and microfibers.
We like Sheex brand performance sheets. They are sold with just the bottom sheet or just the top, so if you prefer not to sleep with a top sheet, you can just buy the fitted one.
Solution #3: a warm mist humidifier.
It's easier to warm humid air. A warm mist humidifier can help make your room warmer without turning up the heat for the whole house. We like top-fill models and ones with larger tanks, so it's easier to refill and you don't have to refill it as often.
Venta is our favorite humidifier/air purifier/diffuser. It's not a warm mist humidifier. It isn't warm or cool. While this product is an investment but it's one of those things you can't live without once you have one. Plus, the Venta has the added benefit of being easy to clean. There are no filters to replace, it uses tap water, is easy to fill, and you can add your favorite essential oil (like sleep-promoting lavender) to the water.
Sleep Issue: You Get Too Cold
Problem: you freeze most nights and spend hours trying to warm up so you can relax and fall asleep. Or you wake up freezing cold during the night.
This problem is easier to solve than sleeping hot. The ideal sleeping temperature is between 60 and 67 degrees Fahrenheit. Most people say 65 degrees. Falling temperatures (like what happens when you go from being warmer to being cooler) help you fall asleep. However, anyone who's been winter camping, knows if you're too cold you won't get great sleep either.
Fact: rooms between 60 and 68 degrees encourage the body to produce melatonin. Melatonin not only promotes sleep, it's also a powerful anti-aging hormone.
Solution #2: a heated mattress pad.
If, like many of us, you get cold and someone you sleep in the same bed with gets too warm, a dual-control heating mattress pad can help. These go underneath your sheets, but they can't be kicked off or fall off the bed.
We have this heated mattress pad (pictured below), and like how quickly it heats up. You can set it for 1, 2, or 10-hour auto shut-off times. No cords are running underneath, and you don't have to plug in both sides for it to work.
After testing several brands of heated mattress pads, this is by far our favorite:
Solution #3: an electric blanket.
Most electric blankets are made from polyester, which is naturally more flame-retardant and keeps its shape better after washings. Cotton is softer but less flame resistant. You can also get fleece heated blankets.
What to look for in an electric blanket
Thicker is better for warmth, and if a blanket is too thin, you risk being able to feel the wires through the blanket, which isn't very cozy at all.
Your electric blanket or heated mattress pad can get stains and odors. So find one with detachable controls (like the heated mattress pad pictured above). That way, you can wash and dry it to keep it sanitary. Washing your blanket wrong can ruin it, so check the instructions and follow them. Every heated blanket and mattress pad we link to in this article is machine washable.
Look for an electric blanket with the cord on the side, not down the middle, so you can plug it into the nearest outlet. Is the cord long enough? Also, it's easier to make the bed without dealing with the cord in the middle.
Your blanket’s controls should also be simple to see and use, even at night. If you sleep with someone else, dual controls are so helpful. Also, some blankets have one setting, and others have many temperature settings to choose from. This one has 10. We prefer a digital readout over a dial because it's tough to maneuver dials in your sleep. The one we linked to has a dimmer so as not to keep you awake.
If you haven't found what you're looking for, here are more bed cooling options.
