However, the cost of all those sleepless nights is more than just bad moods and a lack of focus.

Regular poor sleep puts you at risk of serious medical conditions, including obesity, heart disease and diabetes – and it shortens your life expectancy.

It’s now clear that a solid night’s sleep is essential for a long and healthy life.

How much sleep do we need?
Most of us need around 8 hours of good-quality sleep a night to function properly – but some need more and some less. What matters is that you find out how much sleep you need and then try to achieve it.

As a general rule, if you wake up tired and spend the day longing for a chance to have a nap, it’s likely that you’re not getting enough sleep.

A variety of factors can cause poor sleep, including health conditions such as sleep apnoea. But in most cases, it’s due to bad sleeping habits.

What happens if I don’t sleep?
Everyone’s experienced the fatigue, short temper and lack of focus that often follow a poor night’s sleep.

An occasional night without sleep makes you feel tired and irritable the next day, but it won’t harm your health.

After several sleepless nights, the mental effects become more serious. Your brain will fog, making it difficult to concentrate and make decisions. You’ll start to feel down, and may fall asleep during the day. Your risk of injury and accidents at home, work and on the road also increases.

If it continues, lack of sleep can affect your overall health and make you prone to serious medical conditions, such as obesity, heart disease, high blood pressure and diabetes.
