We all have a circadian rhythm, also known as your body clock or sleep-wake cycle, that acts as your body’s internal timing device. Primarily responsive to light and darkness in the environment, the process enables our bodies to follow a daily pattern of physical, mental, and behavioural changes that help us know when to sleep, wake, eat, exercise and even work.A disrupted body clock can lead to poor quality sleep, weight gain and even health problems, such as cardiovascular disease and diabetes.
Here are six strategies to help reset your inner timer.
1. Switch off your screen at night
Light is the main influence on your body clock and looking at the bright light of a laptop screen in the evening can disrupt its natural balance. Phone screens and computers have a bluer wavelength than other lights, which disrupt more than other, yellow, lights.
2. Avoid coffee in the evening
Scientists have now proven what most of have experienced already, that coffee keeps you awake. Coffee pushes back the release of the circadian hormone melatonin, which tells your body when it’s time to sleep. Because its release is delayed, your body doesn’t think that it is night time until later and will keep you awake.
3. Avoid social burnout
Your body clock likes routine and late nights can throw your body out of sync. Try to go to bed around the same time most evenings to help restore your body back to normal service.
4. Eat at regular meal times
Breakfast, lunch and dinner are signals to our body to fire up our metabolism and fuel up during our active hours of the day. Eating erratically can confuse this signal and knock our body clock of course.
5. Stay cool
Keeping your bedroom cool can help to bring your sore temperature down and signal to your body that it is time for sleep. The optimal bedroom temperature for a good night’s is below 21 degrees Celsius (70 degrees Fahrenheit).
6. Invest in circadian lighting
Circadian lighting systems are specifically designed to use feedback from the environment to control the colour and intensity of the light at particular times. Blue wavelengths are beneficial during daylight hours because they boost attention, reaction times and mood, but can have a disruptive affect at night. These can be controlled throughout the day and set to transition towards darkness in the evening.
