How to get deep sleep, and why it's so important

Sleeping well doesn't always mean resting well. And even if we manage to sleep the recommended hours, we often still wake up tired, with a foggy mind or the feeling of not having switched off all night. In many cases, the reason lies in a lack of deep sleep, a key phase of rest that usually goes unnoticed, but which has a direct impact on our energy, concentration and emotional health.

In this article we're going to delve into what exactly deep sleep is, how it influences your daily wellbeing, what factors can reduce its quality or duration and, above all, how you can increase it naturally through habits, strategies and natural nootropics.

What deep sleep is and why it's so important

Deep sleep is one of the most restorative stages of rest. It's found within NREM sleep, non-rapid eye movement, especially in phases 3 and 4, known as slow-wave sleep. During this phase:

1. The body regenerates at a cellular level.

2. Essential hormones are released, such as growth hormone.

3. The immune system is strengthened.

4. Memories are consolidated and brain toxins are cleaned out.

Without enough deep sleep, sleep quality is compromised, even if you sleep eight full hours.

How long should we spend in deep sleep

An average adult spends between 13% and 23% of the night in deep sleep. That's equivalent to about 60 to 110 minutes per night, depending on age, physical condition, stress and lifestyle habits.

This time is usually greater in children and adolescents, and decreases with age. However, a good routine can help you improve deep sleep even in adulthood.

At what time is sleep deepest

Deep sleep mainly occurs during the first third of the night. That is, if you go to bed at 11:00 pm, your deepest and most restorative phases will be approximately between 11:30 pm and 2:30 am.

During this interval it's essential that rest isn't interrupted, since it's when the body activates its most intense recovery functions.

How to increase deep sleep naturally

There are real, sustainable and natural strategies to increase the duration and quality of deep sleep. And no, we're not talking about instant solutions, but about an approach based on consistency and healthy habits.

Create a consistent sleep routine

Going to bed and waking up always at the same time helps regulate your circadian rhythm, facilitating the passage through all sleep phases, including the deepest one.

Turn off screens at least an hour before sleep

Exposure to the blue light of phones, tablets or television reduces melatonin production, making it harder to fall asleep and access the deep phases.

Avoid heavy dinners and caffeine after mid-afternoon

Heavy digestion or stimulants can keep you in states of alertness that interfere with deep sleep. Opt for light dinners without stimulants.

Integrate magnesium into your night-time routine

Magnesium is one of the most relevant minerals in the quality of rest. It helps relax the nervous system, reduce cortisol levels and facilitate the passage into the deep phases of sleep.

Does magnesium keep you awake

On the contrary: numerous studies confirm that magnesium, especially in forms such as citrate or bisglycinate, promotes falling asleep and the depth of sleep. It's one of the most used ingredients to improve deep sleep naturally.

*Extra tip: protect above all the first three hours of sleep. Bringing your bedtime forward by twenty minutes pays off more than lengthening the morning, because deep sleep is concentrated at the start of the night and isn't recovered later.

How to achieve real and restorative rest

The body needs signals to rest deeply. When we create the right environment and habits, we're telling the brain that it's safe to switch off.

Relaxation before sleep, accompanied by a calm environment, a consistent routine and natural support like the nootropics from ZZEN Labs, can make the difference.
