In our fast-paced world, the concept of time governs much of our daily routine, yet one crucial aspect frequently overlooked is our internal biological clock or circadian rhythm. This internal timer plays a vital role in dictating our sleep patterns, hormone release, eating habits, and overall health.

Johanna Altman, a wellness enthusiast and advocate for holistic health practices, shares insights on how properly managing light exposure can significantly enhance circadian health and, by extension, improve overall well being.

Understanding Circadian Rhythms
Circadian rhythms are physical, mental, and behavioral changes that follow a 24-hour cycle, responding primarily to light and darkness in an organism’s environment. They are found in most living things, including animals, plants, and microbes. The study of circadian rhythms is called chronobiology.

The Role of Light
Light is the most potent cue influencing circadian rhythms, helping to synchronize the internal clock to the environment’s 24-hour light/dark cycle. Natural sunlight and artificial indoor lighting impact these rhythms, signaling when it’s time to wake up and when it’s time to sleep.

The Impact of Circadian Misalignment
Disruption to the circadian rhythm can lead to various health issues, including sleep disorders, obesity, diabetes, depression, bipolar disorder, and seasonal affective disorder. Johanna Altman emphasizes that understanding and managing our light exposure is key to preventing such disruptions and maintaining good health.

Harnessing the Power of Light
Sunlight: The Best Circadian Regulator
Exposure to natural sunlight during the day is crucial in keeping the circadian rhythm healthy. Johanna recommends starting the day with a morning walk or simply sitting by a sunny window. This exposure helps halt the production of the sleep hormone melatonin, making us alert and ready to start the day.

Artificial Lighting: Friend and Foe
While natural light is beneficial, artificial lighting can be a double-edged sword. During the day, bright artificial light can help maintain alertness and focus, mimicking the benefits of natural sunlight. However, excessive exposure to artificial blue light from screens and LED lights in the evening can disrupt the body’s natural preparation for sleep by inhibiting melatonin production.

Blue Light and Sleep
The blue wavelengths produced by our electronic screens are beneficial during the day because they boost attention, reaction times, and mood, but they are the most disruptive at night. To mitigate their impact, Johanna uses apps that filter the blue/green wavelength at night, or she wears glasses that block blue light in the evening.

Practical Tips for Optimal Light Management
Johanna Altman shares several strategies to harness the power of light effectively to support your circadian rhythm:

Maximize Daylight Exposure
Get outside: Aim for at least 30 to 60 minutes of outdoor light exposure daily, especially in the morning.
Position your workspace: Arrange your work area so that it receives ample daylight, using windows and skylights wherever possible.
Manage Indoor Lighting
Brightness: Keep indoor lights bright during the day to mimic natural sunlight, especially if your exposure to natural daylight is limited.
Dim lights at night: As the evening progresses, dim your ambient lighting to help signal to your body that it’s time to wind down. Utilize lamps instead of overhead lights.
Technology and Blue Light
Use technology wisely: Leverage apps and settings on smartphones, tablets, and computers that reduce blue light exposure in the evening.
Set a technology curfew: Try to turn off electronic devices at least an hour before bedtime to give your body a break from blue light.
Consistency is Key
Regular sleep schedule: Going to bed and waking up at the same time each day sets a routine that your body can adapt to.
Pre-sleep routine: Establish a calming pre-sleep routine that begins at the same time each night.
The Benefits of Light-Based Circadian Regulation

Proper management of light exposure can lead to numerous health benefits:

Improved sleep quality and duration: Aligning light exposure with your body’s natural circadian rhythm can promote better sleep patterns.
Enhanced mood and cognitive function: Regular sleep cycles and natural light exposure are linked to improved mood and sharper cognitive functions.
General health and wellbeing: Synchronizing your circadian rhythm enhances metabolic processes, boosts immune function, and reduces the risk of chronic diseases.
Conclusion
Resetting your internal clock using light is a powerful yet often underutilized strategy for enhancing circadian health. As Johanna Altman illustrates through her daily practices, making thoughtful adjustments to our light exposure patterns can lead to significant improvements in our health and quality of life. By understanding and respecting the natural cycles of our bodies, we can live more harmoniously within the rhythms of the day and lead healthier, more balanced lives.

Algorithmic (Algo) trading also called as the automated trading or black-box trading, is the new era of stock marketing. Those who are deeply involved in algo trading, they found this system worth to use and invest time on for its multiple features and real-time trading ability. Algo trading is a complex method using mathematical routes to understand and gain profit. Automates stock marketing comes with defined sets of instruction based entirely on timing, price, quantity and mathematical model.

Here is the short example of algo trading -

A trader buys 50 shares of stock when it is in the 50-day moving average going above the 200-day moving average.
Sell shared of the stock when its 50-day moving average goes below the 200-day moving average.
By using these two simple instructions, the computer program will monitor the stock price. It will then place the buy and sell order if the condition is met. The traders do not have to monitor live prices and graphs because the system would do it manually.

To use and gain profit from automated trading, the user needs to understand critical components. However, let us first check some of the benefits of algorithmic trading system

Every possible trade is executed with the right price.
Instant order placement and accurate
Traders get a real-time update on price change to trade rightly
Automated checks on multiple market conditions
Reduced risk of manual errors while placing possible trades
Reducing the possibility of mistakes from human traders
Key Components of Algo Trading

To perform algo trading, the trader should know the key components. These strategies can improve your costing and earnings-

Identifying the Strategies
To have successful trading using the software method, it is essential to identify strategies on which market is suitable for trading. This will allow developing logic before trading. The best thing of using trading software is it automatically trades if it finds the stock suitable.

Back testing the strategy
Stock trading or marketing entirely relies on testing the data. Algo Trading software comes with historical data that allows you to backtest the previous trading and according to work on strategies. Here, you will also need to work on proven mathematical models like- delta neutral trading strategy.

Executing your strategy
Once you have backtested the previous data, you can execute the idea based on transaction costs. There is a cost of trading and commission, which you will need to work upon to ensure you do not have to pay beyond the required limit.

Manage Risk
Once you have executed the trade, it is vital to manage risk by creating pre-and-post trade checks. This will help in avoiding losses.

Technical Requirements
For successful algo trading, you need to be technically upgraded like-

Computer-programming knowledge for trading strategy hired programmers, and pre-made trading software.
Network connectivity and access to trading
Ability and infrastructure to backtest the system before it goes live
Ability to avail and learn historical data for backtesting
