Sleep Science

At first glance, flying might seem glamorous or efficient. But anyone who has ever stepped off a red-eye flight with puffy eyes, aching limbs, and a dazed mind knows this truth: airplane travel plays havoc with your sleep. Beyond the cramped seating and airline food lies a deeper problem. Flying disturbs not just your rest, but your hormonal balance, circadian rhythms, and even your emotional well-being. In this blog, we explore the scientific underpinnings of why travel by air is so disruptive, and more importantly, how you can overcome it with preparation, insight, and the supportive embrace of NadaUp's scientifically designed mattresses and pillows.

At the heart of ancient Chinese philosophy lies a symbol that transcends time and culture: the Yin-Yang. This elegant swirl of black and white embodies the fundamental truth that all life is a dynamic balance between opposing forces. Darkness and light. Stillness and motion. Cold and warmth. Feminine and masculine. In Taoist thought, harmony is not the elimination of one force over the other, but the dance between them—a continual ebb and flow that restores peace, health, and vitality.

Trust is the invisible thread that holds human connections together. At its core, trust is the psychological state in which we accept vulnerability based on positive expectations of another’s intentions or behavior (Rousseau et al., 1998). It is not just a feeling—it’s a foundational mechanism that governs relationships, decisions, and loyalty in both personal and professional contexts. In an age dominated by technological leaps, instant gratification, and algorithmic precision, one might argue: “Oil was once a currency. Then data became the currency. But now?”—Trust is the new currency. It’s the only tender accepted in matters of love, business, politics, and yes—sleep.

We’ve all been there. It’s past bedtime, but we’re still glued to our phones—catching up on messages, scrolling through social media, or reading the news. In a world where digital devices are nearly inseparable from our daily lives, this habit may seem harmless. However, research reveals that nighttime screen exposure could be seriously sabotaging your sleep, raising stress levels, and affecting how energetic you feel the next day. A good night’s sleep is not just about closing your eyes. It’s about aligning with your body's natural rhythms and giving your hormones the right environment to do their jobs. Unfortunately, your phone might be throwing everything off balance.

Emotions are more than fleeting feelings; they are intricate biochemical and physiological responses to our perceptions of the world. As Dr. Bradley Nelson eloquently states in The Emotion Code, emotions are “energy in motion.” When these emotional energies are not fully processed, they can become lodged in our bodies, manifesting as pain, illness, or mental fog. Nelson writes, “Trapped emotions are literally balls of energy, vibrating at different frequencies depending on the emotion” (Nelson, 2007).

Love is one of the most profound human experiences, but its essence is often misunderstood. Some say love is a feeling, others call it chemistry, and many think it’s simply about connection. But what if love begins in a place you never thought to look—within yourself, in silence, in stillness… in sleep? At NadaUp, we believe love is a state of being, not just a fleeting emotion. And surprisingly, your mattress—the place where you spend nearly one-third of your life—can be the portal to awakening that love.

Across civilizations, the human body has often been seen as more than a physical vessel — a mirror of the cosmos, a temple of the spirit, a bridge between seen and unseen. In this piece, ancient wisdom converges with contemporary insights to explore how the body, mind, and spirit are deeply intertwined, and how the subtle energies within us may shape the quality of our lives — down to how we sleep and heal.

Every morning you wake up, yawn, stretch, and begin a day that feels “normal.” Yet, beneath your awareness, your cells are performing an ancient dance—a choreography dictated by a language written in four letters: A, T, C, and G. This is your DNA, and far from being a static script, it is an adaptable score waiting for your conscious choices to press "play" on the right melody.

Do you wear a smart band or watch while sleeping? If yes, you’ve probably noticed something intriguing—your heart rate. It’s more than just a number. A steady nighttime BPM (beats per minute) is a key marker of good health. But what if your heart is racing while you're in deep slumber? Your heart should slow down during sleep to aid recovery and maintain hormonal balance. A consistently elevated BPM can be a warning signal, and understanding the causes is the first step toward fixing it. Below are 10 reasons your heart rate might spike during sleep—and what you can do about it.
