For all these years, experts have researched this topic. In this blog, we have gathered all the information to help you understand how to get more deep sleep, its advantages, and much more. Let’s get started by understanding what deep sleep is.

What Is Deep Sleep?

Deep sleep, also referred to as slow-wave sleep, is a kind of non-REM sleep. In this type of sleep, the brain waves slow down, and the body feels much fresher after waking up. Slow-wave sleep also restores the body from the daily activities that include healing of injuries, releasing growth hormones, strengthening the immune system, and regeneration of cells. As per studies, the average adult needs 7 to 9 hours of sleep and roughly spends 10-15% of his night sleep in a deep sleep cycle.

Why Is Deep Sleep Important?

Deep sleep is unarguably the most significant part of our sleep cycle. Deep sleep is also known as “sleep-dependent memory processing,” meaning it consolidates new memories. Slow-wave sleep also improves declarative memory, which includes both semantic and episodic memory. Deep sleep also facilitates a High arousal threshold and Presumed restoration of the body and brain. Let’s understand how to induce deep sleep in the next section.

Tips for Getting More Deep Sleep 

Here are the tips to improve deep sleep continuity.

1. Prepare a Sleep Schedule

Preparing a proper sleep schedule is the stepping stone to getting more deep sleep. Decide a fixed time to go to bed, and try to go to bed at that particular time itself, without any excuse. Similarly, set up a wake-up time and wake up at a fixed time every day. It will regulate the circadian rhythm of your body and helps you get a quality deep sleep.

2. Limit the Use of Digital Devices

The best way to get deep sleep is to avoid the blue light from electronic devices; it disrupts melatonin production and disrupts the circadian rhythm. So, if you’re trying to get your cycle to run normally again, we recommend avoiding screens like mobiles, television, tablets, laptops, etc., within an hour before bed.

3. Exercise Daily

Exercising daily for about 30 minutes increases the chances of deep sleep by increasing your heart rate and movement of your muscles. It also releases endorphins that help you be awake. It also increases your exposure to the sun and decreases the production of melatonin during the daytime.

4. Consume a Healthy Diet

Consuming heavy meals before getting into bed leads to acid reflux, indigestion, and heartburn, which may disrupt your deep sleep. Still, if you want to snack at night, consume a light snack rich in protein and low in carbohydrates and fats like fruits, vegetables, dry fruits, milk, cheese, etc., which can have many health benefits without impacting your deep sleep.

5. Try Yoga and Meditation

What better than a natural way to increase your deep sleep. Not only is yoga a great way to center your body and mind, but it can also promote better sleep quality. According to a recent study, people who performed yoga and meditation daily got deep sleep quickly— If possible, try to practice yoga right before your bedding time; it is a great way to calm your mind.

6. Reduce Caffeine Consumption

We all are obsessed with caffeine. But consuming excess caffeine makes it hard for you to fall asleep quickly. Inevitably it also reduces the amount of deep sleep you get. We recommend you having caffeine at least six hours before bedtime. You can consume other noncaffeinated drinks such as water, tea, or milk. These beverages help in inducing sleep.

7. Keep the Nights Dark

Try keeping your bedroom dark. A dark room leads to melatonin production and sets the circadian rhythm.

The temperature of your room also impacts your deep sleep. According to studies, sleeping in scorching temperatures can decrease deep sleep. A process named thermoregulation maintains the core temperature of the body. If you cannot control your room temperature, try wearing light sleepwear and sleeping on cool, breathable Bedding.

8. Create a Relaxed Environment

As mentioned above, a boiling room can decrease sleep quality. Try cooling the room with the thermostat or other temperature controlling devices.

You can create a calm sleeping environment by using dim lights, keeping the electronic devices away, using soft and comfortable Bedding, curtains, and wearing earplugs.

9. Select the Right Bedding

All said and done; you cannot get a comfortable deep sleep without the right choice of Bedding. Try using soft foam bedding made up of natural materials such as cotton, latex, and bamboo to ensure you sleep cool. These materials are more breathable, comfortable, and cozy than fabrics like polyester or microfiber.

10. Try Aromatherapy

Using oils releases tension and lowers heart rate, and makes you feel more calm and relaxed. Using Oils such as lavender, Bergamot, Clary Sage, Valerian, Sandalwood, Ylang-ylang, and Jasmine daily can improve your deep sleep to a considerable extent.
