Happy Hour challenge

 

We are at heart a wasteful society - and it seems that the intrinsic value of daylight is no exception. For large chunks of the year we often sleep when it is light and we are awake in the depths of darkness.

Such is the folly of modern society that our natural circadian rhythms and the balance between day and night have been brutally squeezed by modern electricity's triumph over the night. Bright lights are the norm and night is more of an optional experience.

Here in the northern hemisphere we are plunging headlong into days of less daylight and longer nights. And this Sunday our country will change the clocks by putting them back one hour, in what Sir Greg Knight MP describes as a “flawed annual ritual”.

According to Sir Greg the answer is to bring our waking hours more in line with the hours of daylight - rather than ‘waste’ daylight in the early morning when most of us are still asleep       

“Our current, self-chosen time settings mean that for most of winter days, people at work, college or school have little or no sunlit leisure time,” he says.

“The answer is to put our clocks forward an extra hour all year round and move to a system of Single/Double Summer Time (SDST).”

Evidence for the positive effects of shifting the clocks forward is mounting. Research indicates that any increase in road casualties during a darker morning rush hour in winter would be more than offset by a decrease in road casualties as a result of lighter afternoons.

Knock-on benefits of reduced electricity bills and improved health (less Seasonal Affective Disorder) in the winter, combined with a boost for the leisure and tourism on late summer days, mean that such a change has a growing band of champions.

Old arguments about milkmen and postal workers needing early-morning sunlight to carry out deliveries look exactly like what they are – arguments from when life was very different.

The National Farmers’ Union, at one time a staunch critic of any change, now says the reasons for farmers' past opposition to advancing the clocks have been “lost in history” (and probably modern technology).

A grassroots campaign is aiming to prove there is an alternative to dark winter afternoons – and at the same time raise awareness about the benefits to our health, the environment and economy of managing our time in a different way.

This weekend the Happy Hour challenge is encouraging people to discover for themselves the social and health benefits of SDST – for just a couple of days.

Chris Hayes, campaign co-ordinator, says: “As well as raising awareness about positive emotional well-being and freedom, this is also all about changing the way we do politics and policy; getting people to actually experience and try things out rather than debating abstract policy concepts.”

“We don't want to prescribe how people take on the challenge but ideally it is to leave the clocks alone on Sunday and spend all of that day and then next an hour ahead of everyone else (GMT+1),” he explained.

Rebecca Harris MP also supports SDST. “The Happy Hour campaign is a great way to show how people could benefit in a practical way from keeping an extra hour of light in the afternoons,” she says.

“Whether it's getting more exercise, sport and recreation or saving cash by using less artificial lighting it would clearly be of public benefit. And road safety organisations are adamant that more daylight in the late afternoon will save many lives and serious injuries.

“I hope the Happy Hour campaign will get more people thinking about how they would use an extra hour’s afternoon light and convince the political parties to commit to include it in their manifestos.”

Whilst the beauty of SDST is its ability to deliver much for little cost - the devil is in the politics. Happy Hour offers the chance to try it out in a fun way. So why not leave your watch on BST and give it a go?

Your body certainly won’t notice the difference for a couple of days. And while everyone else is complaining about how dark the afternoon has suddenly become you can enjoy an extra hour in the park or garden.

Let there be light

The Milky Way strode across the sky, a band of faint light spanning almost from horizon to horizon. In the distance, lights sparkled like ships on a dark ocean. Such a dark sky with a myriad twinkling stars is a sight that is becoming all too rare - or even beyond the experience of many.

This is the heart of the Fens at night. A natural planetarium with glorious low horizons in every direction and a pitch dark sky, just far enough from the sodium city lights of Peterborough and the market towns of Stamford and Spalding.

Indeed, this part of South Lincolnshire, an industrial farming and food-producing landscape by day, is by night one of Britain’s dwindling exceptions to our light-polluted lives.

According to the Council for the Protection of Rural England (CPRE), places with the ‘purest’ night-time darkness are (perhaps by definition) among the least populated in the country.

Dartmoor, Exmoor and the Quantock Hills in the south west; Salisbury Plain and the top of the Chilterns in southern England; parts of Lincolnshire to the east; the Black Mountains and the Brecons in Wales; the Yorkshire moors and some of Northumberland; plus large swathes of Scotland, outside major cities and the Borders.

Early this year Sark – the smallest of the four Channel Islands at just a couple of square miles – became the world's first officially-designated ‘Dark Sky Island’.

The US-based International Dark-Sky Association measured Sark's night-time illumination levels and assessed the degree of visibility of constellations in the night sky. And to assist Sark's claim, one of its government officers visited every outside light on the island and recommended measures to cut artificial light seeping into the sky.

Sark is not Britain's only dark success. In 2009 Galloway Forest in Scotland was designated Europe's first ‘Dark Sky Park’. As a result visitor numbers are booming, a new observatory is planned for the edge of the forest and neighbouring local councils have introduced restrictions on outside lighting to preserve the quality of darkness.

The Inner Hebrides’ island of Coll, 13 miles long and three miles wide with two main roads and a small airport, is another dark spot with no security lights on homes, or traffic or street lights.

Much closer to home, the Rutland village of Market Overton recently reduced its light pollution by replacing its old sodium street lights with modern light-emitting diode lamps. Its 39 lamps cost over £20,000 in total to convert but immediately produced an 80 per cent saving in electricity.

These locations, however, remain the exceptions to the light-polluted rule. And they are getting rarer thanks to what the Campaign for Dark Skies describes as ‘wasteful’ over-provision of domestic lighting by British householders.

CPRE has, for several years, urged government action to limit light pollution from street lamps, overnight illumination of shopping centres, office blocks and public buildings, stark upward lighting from floodlit sports complexes and, at the household level, outdoor lights that are unnecessarily bright or disperse their illumination. Of course it would also save a lot of money and energy too – Britain's street lamps alone cost an estimated £500 million a year to run.

The most common forms of such pollution are ‘light trespass’ when illumination from Britain's 22 million homes and 7.5 million street lights, even if designed with the intention of shining downwards, typically also extends upwards. You can see it in this picture of the UK at night as seen by astronauts passing overhead aboard the International Space Station.

Two other common forms are ‘sky glow’ – that orange glow visible for tens of miles around towns and cities easily seen from the air or from distant roads – and ‘glare’, the harsh white light on some modern housing estates and golf driving ranges at night.

As October marches onwards, here in the northern hemisphere we are plunging headlong into days of less daylight, longer nights and the clocks going back – all marking the onset of winter. And, while we say we prefer it lighter for longer, in reality most of us only now experience a limited degree of darkness.

Modern electricity's triumph over the night keeps us all busier. We live in a fast-moving, fully lit world where night still happens but is more of an optional experience – a kind of failed daylight. Our 24/7 supermarket culture has done it’s best to phase out the night.

Yet slowness and silence – the different rhythm of the night – are a necessary correction to the day. Life is too short to be all daylight. Moments of life take on a different quality at night-time, where the moon reflects the light of the sun and we have time to reflect what life is to us. So why not turn down the lights and rest awhile? Night is not less – it's more.
