As the brilliance of autumn gradually fades, the presence of winter draws closer.

Days grow shorter, nights grow longer.

Sunlight seems to dim as if someone pressed a “weaken” button.

Even our mood appears to shift into “grayscale mode.”

Many people find that once winter arrives, they tend to feel low: difficulty getting up in the morning, low energy during the day, and trouble falling asleep at night; an increase in appetite, especially for carbohydrates and sweets; a lack of interest in usual activities, with a desire to stay at home and zone out…

This may not be “winter laziness,” nor is it simply being “overly sensitive.”

It could be Seasonal Affective Disorder (SAD) quietly influencing you.

Less Light, Changing Mood

Seasonal Affective Disorder (SAD) is a form of low mood triggered by seasonal changes. It often appears during autumn and winter and naturally eases in spring and summer.

Reduced sunlight is the primary factor:

Studies show that when light exposure decreases, the brain produces less serotonin—the “feel-good” hormone—while melatonin, which promotes sleep, increases. This disrupts the body’s circadian rhythm, leading to a drop in mood.

So when you feel down or unmotivated in winter, it may be your body’s way of saying: it’s time to replenish some light.

Light: The Body and Mind’s Natural “Switch”

Daily exposure to sunlight not only helps the brain release serotonin, but the near-infrared wavelengths contained in sunlight can also activate cellular mitochondria, promote energy metabolism, and enhance the body's vitality.

Unfortunately, ideal sunlight is not always easy to get.

You leave home before sunrise and return after dark;

even when there is daylight outside, it may not reach you directly;

and with occasional smog and overcast weather, even weekends can pass without sunshine.

In short: you want sunlight, but opportunities are limited.

LifeGlo Vitality Lamp: Bringing “Sunlight” to Every Day

The LifeGlo Vitality Lamp simulates the natural sunlight spectrum, avoiding ultraviolet rays and harmful blue light while preserving the “golden band” of near-infrared light. This helps improve issues caused by insufficient light exposure, such as fatigue, circadian rhythm disruption, and low mood, supporting the body in restoring balance and energy.

Ten minutes in the morning helps signal the body to “power on”;

a short session in the afternoon helps push away drowsiness and “recharge”;

and at night, its warm light allows the body and mind to naturally relax.

On days when sunlight is absent, give yourself a little extra brightness—

warm, steady, and comfortable, like a small patch of winter sunshine.

The LifeGlo Vitality Lamp — your winter source of light and energy.
