Our core body temperature follows a distinct pattern throughout the day, synchronised with our circadian rhythm. This temperature fluctuation closely mirrors our alertness levels. When our core temperature is higher, we tend to be more alert and productive; conversely, when it's lower, we naturally feel more inclined to sleep or rest.

This natural temperature fluctuation is influenced by various factors, including the release of hormones like melatonin and cortisol, as well as environmental cues.

Here's how core body temperature typically varies over a 24-hour period:

• Morning (Around 6 AM): Our core body temperature starts to rise, signalling the body to wake up. This increase in temperature is associated with the release of cortisol, a hormone that helps us feel alert and ready for the day.
• Mid-Morning to Early Afternoon: Core body temperature continues to increase, reaching its peak in the late morning to early afternoon. During this period, our cognitive functions, such as problem-solving and concentration, tend to be at their best. This elevated temperature supports our natural circadian alertness.
• Afternoon to Evening (3 PM - 6 PM): Core body temperature gradually begins to decline from its peak. This decrease is part of the natural circadian rhythm and can lead to a temporary drop in alertness, often referred to as the "afternoon slump."
• Evening (6 PM - 9 PM): As evening approaches, core body temperature continues to decrease. This decrease signals to the body that it's time to wind down and prepare for sleep. Melatonin, a hormone that promotes sleep, is released in response to the declining temperature.
• Late Night (10 PM - 4 AM): Throughout the night, core body temperature remains at its lowest point, supporting deep and restorative sleep. This low temperature allows the body to conserve energy and repair itself during the sleep cycle.

Workspace Temperature & The Circadian Alerting Zone

For most people, the ideal core body temperature for productivity tends to be around 37°C or slightly higher during these peak hours. This period is often referred to as the "circadian alerting zone." During this time, you may find that your cognitive functions, such as problem-solving, decision-making, and focus, are at their best.

To optimise productivity, consider scheduling tasks that require high cognitive demand during these hours. This could include important meetings, creative work, problem-solving, or tasks that require deep concentration.

It's essential to maintain a comfortable workspace temperature that supports productivity. Cooler temperatures, which align with the circadian alerting zone, can help keep you alert and focused. However, individual preferences can vary, so it's important to find the temperature that works best for you within this range.

Remember that everyone's circadian rhythm is slightly different, and factors like age, genetics, and lifestyle can influence your peak alertness times. Therefore, it's valuable to pay attention to your own body's signals and adjust your schedule and workspace temperature accordingly to maximise productivity.

A workspace that aligns with your body's temperature fluctuations can enhance your overall productivity and well-being.

• Daytime Productivity: Maintaining your natural core temperature (i.e not getting too hot or too cold) during the day supports heightened alertness, making it easier to concentrate and perform tasks efficiently.
• Evening Preparation: As evening approaches, lowering the workspace temperature can signal to your body that it's time to wind down. This is especially beneficial if you work late hours, helping facilitate a smoother transition to a restful state.

Temperature Control Techniques:

Achieving an optimal workspace temperature involves more than just adjusting the thermostat. Here are some practical techniques to regulate temperature effectively:

• Thermostat Settings: Invest in a programmable thermostat that can adjust the temperature based on your daily schedule. Set it to maintain a cooler temperature during the day to coincide with your peak alertness.
• Layered Attire: Keep a range of clothing options in your workspace to adapt to changing temperatures. Layering allows you to adjust your clothing to stay comfortable as your body temperature fluctuates.
• Natural Ventilation: Ensure proper ventilation in your workspace to help regulate temperature. Fresh air circulation can prevent overheating during the day and promote better sleep quality at night.
• Personal Preferences: Individual temperature preferences vary. Experiment with different settings to find what works best for you and aligns with your circadian rhythm.
