This article is a part of CNN Underscored’s Guide to Sleep, a week-long focus on the best sleep-related products. We’ll be featuring new products and guides all week, so check in every morning to see what’s new and keep your eyes peeled for exclusive deals.

We live in challenging times, and one thing that’s been so challenging for many of us is putting worry aside and relaxing into a good night’s sleep. Things like work, stress and your sleep hygiene can impact your quality of sleep, so we talked to experts in sleep and comfort to find helpful tips and tricks so you can rest easier every night.

“The most important thing for a good night’s sleep is to make sure that you set yourself up for success,” says Dr. Michael Grandner, Casper sleep adviser and director of the Sleep and Health Research Program at the University of Arizona. “That means removing barriers to sleep like caffeine, reducing distractions close to bedtime, giving yourself enough time to wind down and keeping your bedroom cool, quiet, dark and comfortable.”

Upgrade your pillow

“Something that I was taught through my years of physical therapy is called a spring test,” explains physical therapist Dr. Karen Joubert. “If you take your pillow and you fold it in half and it doesn’t bounce back, it means that pillow’s lost its integrity. And it’s probably time for a new pillow.”

However, what kind of pillow is right is up to you, says Grandner. “A good pillow is one that is firm enough but soft enough,” he says. “That may differ from one person to another, but the ideal pillow is one that balances comfort with the ability to maintain its level of support throughout the night.”

For side sleepers, this firm foam pillow is ideal for keeping the spine straight, says Grandner.

Writes one reviewer: “For over a month, I’d been waking up with a sore neck and tight shoulders, which I knew had to be caused by my pillow. Since finding a good pillow is even more difficult than finding a good bra or pair of jeans, I asked my chiropractor for a suggestion. She told me about the Casper foam pillow, I went right home and ordered it, Amazon delivered it the next day and I’ve had one full week of great, pain-free, comfortable and uninterrupted sleep.”

Joubert strongly recommends this tiny pillow, saying, “It’s a tiny little pillow, and it goes in between your legs. When you sleep on your side and your knees are together, your knee is kind of pulling on your hip. You really want to lift that leg so that the knee is in line and level with a hip.”

Try a noise machine

“So many of us have gone to bed watching the news, or on our phone, and we can’t shut our brain down,” says Joubert, who recommends this machine. “When you use something like white noise, it retrains the brain. You can focus on something else. It also helps to quiet and slow the brain and the mind down. I think they’re highly effective.”

“Many people, especially light sleepers, appreciate the noise-masking effects of noise machines, drowning out and absorbing other sounds from the environment,” says Grandner, who likes this machine.

Try a weighted blanket

“There is something comforting about a weighted blanket,” says Joubert. “I think that’s a really smart product out on the market.” This highly rated blanket can have a calming effect and help reduce anxiety and promote relaxation.

Eye masks are some of the most effective, inexpensive pieces of sleep technology out there, according to our experts. They are very effective at blocking out environmental light, helping to protect the “nighttime” signal in your body. This one is beloved on Amazon for its molded eye cups that relieve pressure off your eyelids.

Block out the world with blackout curtains

“Blackout curtains are another great way to protect your sleep from environmental light that can disrupt it,” says Grandner. “They can help keep you asleep at night, even when the sun comes back up. Just make sure you open them in the morning!” This highly rated set also blocks out the cold.

These highly rated blackout curtains promise to block out light, cold and noise from the outside world, leading to a better night’s sleep.

Find the right mattress

“A lot of people wait too long before replacing an old mattress. Sometimes, this can make a big difference in nighttime comfort,” says Grandner.

Weight and sleep style can also make a difference, explains Joubert. “Someone who’s lighter, or you sleep on your side, you’re going to want to maybe go with a more medium-soft or a medium-firm mattress.”

If you’re looking for soft, supportive comfort, this highly rated mattress is a true steal at this price.

“Believe me when I say this mattress is perfect,” one reviewer writes. “The mattress is not too soft or too hard, just perfect. I would say it’s very true to a medium-plush feel. Sort of molds to your body, but I don’t find it difficult to get in and out of bed.”

Layers of breathable foam plus springs add a little lift, support and airflow to this highly rated mattress.

You may want to look for a firmer mattress like this one if you’re a bigger person, or sleep on your back, says Joubert. “The heavier you are, let’s say you weigh 200 pounds or more, or you’re a back sleeper, you’re going to tend to maybe fall in the guidelines of the medium-firm to firm mattress,” she says.

Zinus 12-Inch Green Tea Memory Foam Mattress, Queen ($271, originally $289; amazon.com)
