Weekend camping activities reset body clock, scientists say

BBC – Spending a weekend out camping resets the clock inside our bodies that influences sleeping habits, scientists at a US university have discovered.
The team argue that time in the great outdoors could help those struggling to get up in the morning and boost health.
The researchers said swapping bricks and mortar for canvas was not a long-term solution.
But exposing ourselves to more bright light in the day (and less at night) could help.
Our body has a daily “circadian” rhythm that anticipates day and night to co-ordinate how our body works.
It alters alertness, mood, physical strength, when we need to sleep and even the risk of a heart attack as part of a 24-hour cycle.
Light helps the clock keep time, but modern life with artificial light, alarm clocks and smartphones has altered our sleeping habits.
