OPTIMIZE YOUR Circadian RHYTHM TO RISE, SLEEP, THINK AND EAT AT THE IDEAL TIME

⚕️Have you ever wondered what my Circadian clock and your natural biorhythm is?

Are you ready for a natural life that prioritizes wellness?

Want to live with more energy and focus utilizing natural cycles?

Are you keen to have better sleep, improved mood, and body composition?

With Circadian, you can anchor your life to sunrise and sunset to optimize your Circadian rhythm and natural cycles.

TURN YOUR LIFESTYLE INTO MEDICINE IN SYNC WITH YOUR NATURAL BIORHYTHM & ENVIRONMENT

☀️The Circadian app is your natural alarm clock. Circadian uses local times (i.e. sunrise and sunset) plus user settings to calculate your Circadian rhythm, also known as biorhythm. Healthy living and better sleep are natural with Circadian.

THE SCIENCE BEHIND Circadian RHYTHMS (CHRONOBIOLOGY)

? Your body's Circadian rhythm are 24-hour cycles of biological, hormonal, and behavioural patterns. This biorhythm modulates a wide array of physiological processes, including your hormones (i.e. melatonin), sleep, hunger, and metabolism, ultimately regulating body weight, energy, mood, and disease susceptibility.

The 2017 Nobel Prize in Medicine was given for research on Circadian rhythms. Circadian clocks in almost all of your cells govern cellular functioning. When you disrupt your Circadian clocks, chaos in the body emerges.

SET REMINDERS AND ALARMS FOR CRITICAL Circadian EVENTS

? Circadian acts as a healthy alarm clock for your biorhythm in line with natural cycles, like light & dark and the seasons. Start syncing your sleep and activity with nature by setting reminders & alarms for:

● daybreak, sunrise, solar noon, sunset, and nightfall

● ultraviolet light rise & fall (UVA & UVB)

● sleep & wake times

● natural eating & fasting

● ideal exercise times

● best mental activity

ADJUST YOUR SLEEP TO THE SEASONS

? Your biorhythm governs daily functioning, while seasonal rhythms affect longer-term behavioral & metabolic changes. Circadian adjusts your sleep duration dynamically based on the sunshine hours at your location. Let your biorhythm become the alarm clock that keeps you in sync with natural cycles, balances hormones (ie cortisol & melatonin), and leads to better sleep.

EAT & FAST IN LINE WITH YOUR NATURAL CYCLES

?️ Eating and fasting are important cues for your biorhythm. Aligning your eating time with Circadian rhythms is necessary to balancing hormones, lowering inflammation, preventing/reversing disease, and better sleep.
