Beauty sleep

An hour before midnight is worth three afterwards. That’s the age-old adage. Is that true?

I cannot live with less than 7 hours of sleep. I get cranky and less productive with work. The problem with me is sometimes I get caught up with work that I forget the time. This happens whenever I develop a website. That’s why I stopped accepting web development projects. I must have at least 7 hours of sleep. When I was much younger, I could get by with 6 hours of sleep and still feel bright and vibrant. Perhaps it’s my age. No sleep means no new brain cells

The researchers compared animals who were deprived of sleep for 72 hours with others who were not.They found those who missed out on rest had higher levels of the stress hormone corticosterone.They also produced significantly fewer new brain cells in a particular region of the hippocampus.

When the animals’ corticosterone levels were kept at a constant level, the reduction in cell proliferation was abolished.

The results suggest that elevated stress hormone levels resulting from sleep deprivation could explain the reduction in cell production in the adult brain.

and get this . Too little sleep may make you fat. You know I always thought that the less one sleeps, the more calories spent and one would expect to lose weight. During the week where I had less sleep, the weighing scale refused to budge lower and worse , I even gained some weight.

They found that, even after factors such as depression, physical activity, alcohol consumption, ethnicity, level of education, age and gender had been taken into account, people were more likely to be obese the less sleep they had.

While those who had less than four hours sleep were most at risk, people who got only five hours of sleep were 50% more likely to be obese than those who were getting a full night’s rest.

It is important to have seven or eight hours of sleep . Sleeping more than that means we wake up looking puffy and feeling sluggish.

Geoff Wright, an expert in chronobiology (the study of the body clock), says: ‘There are set times when our body clock dictates that various processes take place in hair and skin.

‘From 8pm to 11pm is the time for hydration and stimulation, while 11pm to 3am is the time for nutrition and regeneration, and 3am to 5am is the time for resting.’

Of course, very few adults are in bed at 8pm and, as the hormone that triggers sleep – melatonin – peaks at around 11pm, this is the time we should naturally get tired.

So much health benefits in sleeping early. I need to sleep now.
