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

Deep sleep is one of the most restorative stages of rest. It occurs during NREM (non-rapid eye movement) sleep, especially in stages 3 and 4, known as ‘slow-wave sleep’.

During this phase:

• The body regenerates at the cellular level.

• Essential hormones such as growth hormone are released.

• The immune system is strengthened

• Memories are consolidated and brain toxins are cleared away.

Without sufficient deep sleep, the quality of your sleep is compromised, even if you sleep for a full eight hours.

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

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

Deep sleep occurs mainly during the first third of the night. In other words, if you go to bed at 11 p.m., your deepest and most restorative sleep phases will be approximately between 11:30 p.m. and 2:30 a.m.

During this interval, it is essential that rest is not interrupted, as this is when the body activates its most intense recovery functions.

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

Going to bed and waking up at the same time every day helps regulate your circadian rhythm, facilitating the transition through all stages of sleep, including the deepest.

Exposure to blue light from mobile phones, tablets or television reduces the production of melatonin, making it difficult to fall asleep and reach deep sleep stages.

Heavy digestion or stimulants can keep you alert, interfering with deep sleep. Opt for light, stimulant-free dinners.

Magnesium is one of the most important minerals for quality rest. It helps relax the nervous system, reduce cortisol levels and facilitate the transition to deep sleep phases.

On the contrary: numerous studies confirm that magnesium, especially in forms such as citrate or bisglycinate, promotes sleep onset and depth. It is one of the most widely used ingredients for naturally improving deep sleep.

At ZZEN Labs, we work from a realistic, science-backed perspective to help you improve your rest. We don't offer quick fixes, but rather natural support that can be easily integrated into your routine and help you regain your balance.

Designed to help you fall asleep and stay asleep without interruptions, ZZEN Sleep is formulated with synergistic ingredients that naturally support the onset and depth of sleep:

• Magnesium bisglycinate (300 mg): one of the most bioavailable forms of magnesium, ideal for promoting muscle and neurological relaxation.

• L-Tryptophan (300 mg): an amino acid precursor of serotonin and melatonin, which helps improve mood and regulate the sleep cycle.

• GABA (200 mg): a key neurotransmitter for reducing brain hyperactivity and facilitating the transition to states of deep calm.

• Valeriana officinalis (120 mg, dry extract): a plant traditionally used to reduce tension and improve sleep quality.
• Zinc (zinc citrate) (5 mg): mineral involved in neurological function and melatonin synthesis, essential for maintaining restful sleep.
• Vitamin B6 (pyridoxal-5-phosphate) (1.4 mg): a key cofactor in the production of serotonin and GABA, which contributes to the balance of the nervous system and emotional well-being.

The formula of ZZEN Sleep is designed for those seeking natural help to promote deep sleep, without feeling drowsy upon waking or aggressive effects on the body's natural rhythm.

When daily stress or anxiety makes it difficult to relax and get a good night's sleep, ZZEN Calm can be a great help. Its formula is designed to help balance the nervous system and promote a state of sustained calm, ideal as a natural preparation for deep sleep:

• Ashwagandha KSM-66® (600 mg): A powerful adaptogen that helps reduce cortisol, manage stress, and improve the body's response to mental and physical strain.
• Extracto seco de Azafrán (30 mg)
• Extracto seco de Melissa (200 mg)

ZZEN Calm can be taken in the late afternoon or evening as part of a relaxation routine that prepares the body and mind for deeper, more sustained rest.

The body needs signals to rest deeply. When we create the right environment and habits, we are telling the brain: it is safe to switch off.

Relaxation before bedtime, accompanied by a calm environment, a consistent routine, and natural support such as ZZEN Labs' natural nootropics, can make all the difference.
