How light affects our day-to-day life



In the smart future, every aspect of our lives will be digitised and optimised, including light and our relationship with it. Asli Okar, the marketing manager of Philips Lighting in the Middle East discusses the development of lighting and how it will affect our day to day life in the future.

Light, whether natural or artificial, affects all life on our planet. It is more than just a source of vitamin D for us humans. Philips has recently compiled in a white paper key insights from more than 10 years of ongoing research about the effects of light on our sleep/wake cycle, or what is known as our “circadian rhythm”.

It reveals that the amount and quality of light you are exposed to every day may be responsible for how you feel when you wake, ultimately dictating whether you are more of a morning person or a night owl.

Light plays a crucial role in regulating our circadian rhythm, which is one of our natural biorhythms commonly known as our body clock.

Our body clock is not naturally in sync with our artificial clock. It is slightly slower, running for 24 hours and 30 minutes on average, which means we are naturally inclined to sleep and wake 30 minutes later each day.

If this slower rhythm is not regulated by the end of the week our sleep/wake cycle could be off by more than two hours.

Because of our 9 to 5 lifestyle, we may be getting too little sleep during the working week and sleeping in during the weekends. More sleep at the weekend may compensate for any lack of rest, but can reset a later circadian rhythm the following week, resulting in that “Sunday morning blues” feeling.

Are you aware of the term social jet lag? This is a term coined by researchers to describe how you feel when you reset your sleep/wake cycle but are required to wake earlier to meet daily responsibilities. Like jet lag, you can feel groggy on Sunday morning if your weekend activities have reset your cycle to a later rhythm. Exposing yourself to the right quality of light at the same time each day and night can regulate and synchronize your natural body clock to the clock on your bedside table.

In today’s world, alarm clocks help to manage the time lag created by our slower circadian rhythm.

But looking back into history, humans, like most animals, used the sun and the amount of light during different times of the day to regulate our body clock; this was natural and the human body did this without realising it. The reason being, specific quality of light hitting the photoreceptors in our eyes not only regulates our internal body clock, but can actually reset it every single day.

What should do investors do now?

What does the S&P 500's new all-time high mean for the average investor? 

Should I be euphoric?

No. It's fine to be pleased about hearty returns on your investments. But it's not a good idea to tie your emotions closely to the ups and downs of the stock market. You'll get tired fast. This market moment comes on the heels of last year's nosedive. And it's not the first or last time the stock market will make a dramatic move.

So what happened?

It's more about what happened last year. Many of the concerns that triggered that plunge towards the end of last have largely been quelled. The US and China are slowly moving toward a trade agreement. The Federal Reserve has indicated it likely will not raise rates at all in 2019 after seven recent increases. And those changes, along with some strong earnings reports and broader healthy economic indicators, have fueled some optimism in stock markets.

"The panic in the fourth quarter was based mostly on fears," says Brent Schutte, chief investment strategist for Northwestern Mutual Wealth Management Company. "The fundamentals have mostly held up, while the fears have gone away and the fears were based mostly on emotion."

Should I buy? Should I sell?

Maybe. It depends on what your long-term investment plan is. The best advice is usually the same no matter the day — determine your financial goals, make a plan to reach them and stick to it.

"I would encourage (investors) not to overreact to highs, just as I would encourage them not to overreact to the lows of December," Mr Schutte says.

All the same, there are some situations in which you should consider taking action. If you think you can't live through another low like last year, the time to get out is now. If the balance of assets in your portfolio is out of whack thanks to the rise of the stock market, make adjustments. And if you need your money in the next five to 10 years, it shouldn't be in stocks anyhow. But for most people, it's also a good time to just leave things be.

Resist the urge to abandon the diversification of your portfolio, Mr Schutte cautions. It may be tempting to shed other investments that aren't performing as well, such as some international stocks, but diversification is designed to help steady your performance over time.

Will the rally last?

No one knows for sure. But David Bailin, chief investment officer at Citi Private Bank, expects the US market could move up 5 per cent to 7 per cent more over the next nine to 12 months, provided the Fed doesn't raise rates and earnings growth exceeds current expectations. We are in a late cycle market, a period when US equities have historically done very well, but volatility also rises, he says.

"This phase can last six months to several years, but it's important clients remain invested and not try to prematurely position for a contraction of the market," Mr Bailin says. "Doing so would risk missing out on important portfolio returns."

FFP EXPLAINED

What is Financial Fair Play?
Introduced in 2011 by Uefa, European football’s governing body, it demands that clubs live within their means. Chiefly, spend within their income and not make substantial losses.

What the rules dictate?
The second phase of its implementation limits losses to €30 million (Dh136m) over three seasons. Extra expenditure is permitted for investment in sustainable areas (youth academies, stadium development, etc). Money provided by owners is not viewed as income. Revenue from “related parties” to those owners is assessed by Uefa's “financial control body” to be sure it is a fair value, or in line with market prices.

What are the penalties?
There are a number of punishments, including fines, a loss of prize money or having to reduce squad size for European competition – as happened to PSG in 2014. There is even the threat of a competition ban, which could in theory lead to PSG’s suspension from the Uefa Champions League.

The burning issue

The internal combustion engine is facing a watershed moment – major manufacturer Volvo is to stop producing petroleum-powered vehicles by 2021 and countries in Europe, including the UK, have vowed to ban their sale before 2040. The National takes a look at the story of one of the most successful technologies of the last 100 years and how it has impacted life in the UAE.

How tumultuous protests grew
  • A fuel tax protest by French drivers appealed to wider anti-government sentiment
  • Unlike previous French demonstrations there was no trade union or organised movement involved 
  • Demonstrators responded to online petitions and flooded squares to block traffic
  • At its height there were almost 300,000 on the streets in support
  • Named after the high visibility jackets that drivers must keep in cars 
  • Clashes soon turned violent as thousands fought with police at cordons
  • An estimated two dozen people lost eyes and many others were admitted to hospital

How Islam's view of posthumous transplant surgery changed

Transplants from the deceased have been carried out in hospitals across the globe for decades, but in some countries in the Middle East, including the UAE, the practise was banned until relatively recently.

Opinion has been divided as to whether organ donations from a deceased person is permissible in Islam.

The body is viewed as sacred, during and after death, thus prohibiting cremation and tattoos.

One school of thought viewed the removal of organs after death as equally impermissible.

That view has largely changed, and among scholars and indeed many in society, to be seen as permissible to save another life.
