In 1965 a high school student managed to stay awake for 264 hours; that’s approximately 11 days. There have been a variety of studies that show it is possible to stay awake for 10 days, but in the process, the ability to concentrate, stay motivated, or even retain cognitive function diminished.

Of course, a couple of good night’s sleep then resolved all the issues. However, this is extreme circumstances. Most people sleep every night, which is just as well as sleep and weight loss are intricately connected.

In recent years there has been a huge amount of research into the effects of sleep on health. Sleep isn’t simply a time when your body is passive. It is the time when your body processes the day’s events, restores energy, and balances your body.

Put simply, getting the right amount of sleep can extend your lifespan.  A lack of sleep increases your risk of depression, seizures, high blood pressure, and an array of chronic long-term illnesses.

But what is the right amount? Scientists state that a healthy adult should have 7 hours of sleep per night. Of course, this is slightly variable depending on an individual’s needs and lifestyle.

What is clear is that below 6 hours and over 9 can have a serious effect on your health.

How Irregular Sleep Can Lead To Weight Gain

It may seem confusing that a lack of sleep can result in weight gain, but the answer is actually very simple.

grhelin & leptin sleep and weight lossSleep and weight gain are intrinsically linked by the hormones in your body.

When you sleep, your body balances your hormones. This means reducing the amount of cortisol (the stress hormone), which allows your body to produce other hormones.

Specifically related to sleep and weight loss is the balancing of two hormones:

Ghrelin is a hormone commonly referred to as the hunger hormone. It makes you feel hungry. When you sleep, your levels of this hormone reduce, and you crave food less.

Leptin is the appetite hormone. Sleeping encourages the production of this hormone, which makes you feel full.

Put these together with enough sleep, and you’ll feel fuller throughout the day and less inclined to eat. That puts sleep and weight loss in the same camp.

The opposite is true. If you don’t get enough sleep, you’ll feel hungrier, and your appetite will be increased. In short, you’ll eat more and are likely to gain weight!

A lack of sleep can also slow your metabolic rate, which reduces your ability to convert calories to energy and results in higher fat storage.

It has also been shown that if you don’t get enough sleep, then your body will crave sugar to help it keep functioning. This will result in snacking and consuming more calories than you need. Again, you’ll be looking at weight gain.

Equally, too much sleep can cause similar issues.

Top Tips for Sleeping Better

So, now you know that sleep and weight loss go hand in hand. How do you improve your current level of sleep?

It’s not just the amount you sleep of you need. It's the quality of sleep. All you need is the right motivation and these great tips to improve your sleeping patterns:

Blue Light Exposure

Unfortunately, blue light stimulates the brain, preventing the release of melatonin. This is a hormone released by your body late in the day to prepare you for sleep. If it is suppressed, you’ll struggle to get to sleep.

Don’t forget, being in bed for 8 hours is not the same as getting 8 hours of sleep.

You need to turn any devices emitting blue light off at least 1 hour before bed.

Avoiding Caffeine

But, most people associate caffeine with coffee. Of course, it is present in coffee, but it is also in many other things such as tea or cola.

Think about what you’re eating and drinking late at night. If it has caffeine or another stimulant, try to avoid drinking it within 3 hours of your bedtime.

No Napping!

Napping during the daytime is a recipe for disaster. Your body only needs so much sleep. If you nap during the daytime, then you’ll struggle to sleep at night. Worse, your night sleep is unlikely to be deep sleep, where most of the repair work is done.

If you feel tired during the day, then get up, walk around and get some fresh air. This is not a cue to rely on caffeine or other stimulants.

Build A Schedule

You need to set yourself a bedtime and a getting up time. These should be the same every day of the week, whether you’re at work or not.

This will help your body to regulate sleep and awake times and ensure you switch off quicker, allowing yourself to get quality sleep.

In the process of creating your schedule, you’ll help your body regulate its circadian cycle. This is the natural mechanism that controls when you feel awake and when you feel sleepy.

Setting it correctly will help you to get quality sleep.

Start today by setting your bedtime and waking time and sticking to them.


stress ball sleep and weight lossWe live in a stressful world. But high levels of cortisol in your body will prevent your body from sleeping as it remains in ‘fight or flight’ mode.

You can’t avoid all stress, but you can create a habit that allows you to de-stress before bed.

A warm bath may help as will meditation. You may even like to sit and read for 30 minutes. As long as you’re not thinking about work or other issues, you’ll be helping get your body ready for quality sleep.


Your bedroom needs to be comfortable. Curtains and blinds can keep out streetlights, but don’t make them so heavy that they keep out the sun in the morning.

Your bed must be comfortable. If it’s not, change the mattress.

Above all, the bedroom must make you feel relaxed. This will help you drift off naturally to sleep.


Exercise is good for weight loss as you burn more calories. But it can also help your body to need sleep and therefore ensure you have better quality sleep.

However, you shouldn’t exercise too close to your bedtime as this is the same as a stimulant, making it harder for you to get to sleep.

Talk To A Doctor

However, if the above tips are not helping and you’re still struggling with sleeping, then it is important that you visit a doctor. There may be an underlying cause that they can help you deal with.
