Snooze yourself to health

According to a report published by The Sleep Council in March 2013 the number of Britons getting just five to six hours sleep per night has risen dramatically: 40% of us are not getting the six to nine hours recommended by the NHS.

Why is that? In the majority of cases health conditions, such as depression and anxiety or chronic pain are keeping us awake at night. Many are unable to sleep due to worry, but a great many of us are just not going to bed on time to get the rest we need. Some see sleep as a waste of time, which would be better spent working. Others don’t like going to bed early, because the only me-time they can get is in the evenings, when at last they get home after a long and stressful day at work or when the kids are finally tucked up and asleep. Understandable. But is it wise?

The fact that sleep is something our body just demands is a strong clue that we need it and that it is in fact good for something. If we are prevented from sleeping – and remember: sleep deprivation is a form of torture! – we will die. But even without this drastic outcome, sleep deprivation seriously affects our health.

Well watered – you are probably not dehydrated

Have you always been told to drink at least 8 glasses of water a day? Everybody knows that that’s what you must do, right? And do you find that you are struggling to meet that target?

Even though most health professionals keep repeating the “8 glasses rule”, there doesn’t seem to be any scientific evidence for that.

More on Stress from the Inside

A few weeks ago, I wrote about the body’s stress response, or “fight-or-flight” response. The article described what happens inside the body in a situation of immediate danger – the alarm phase. The changes I described are mainly due to the stress hormone adrenaline. It triggers a cascade of mechanisms designed to save our life. The effects of adrenaline are very short lived.

Coffee – It’s not black and white

Do you love your coffee? And if you do, do you feel guilty about it? After all, coffee seems to be bad for you and many health experts discourage its consumption. But as with most things concerning health and nutrition: It’s not black and white.

We all know people who can guzzle a “venti” (20 fl oz = 600 ml) and still have a nap afterwards, when others only so much as sniff an espresso and are wired all day long. That’s because how you respond to caffeine – coffee’s most predominant active compound – is governed by your genes, some of which affect the way your liver processes caffeine, others influence how the brain reacts.
