Sleep deprivation: tips for staying healthy and productive

Adults have different needs in terms of sleep time, but it is estimated that an adult needs 7 to 9 hours of sleep on average. Yet only 35% of French people sleep well.

The average weekday sleep time is 6 hours 41 minutes, and 28% of French people sleep less than 6 hours a night. On weekends, this figure rises to 7h33. In addition, 25-35 year-olds sleep longer than 35-55 year-olds, with an average of 7 to 8 hours per night(INSV).

Yet sleep is essential for health and productivity.

Causes of sleep deprivation

Sleep deprivation, or sleep deprivation, refers to less rest than is necessary for proper physical and mental functioning. This may be due to too little sleep or poor sleep quality.

Poor sleep can be caused by a variety of psychological, environmental or even physiological factors. Stress and anxiety prevent you from falling asleep, or cause you to wake up at night. Bad lifestyle habits such as excessive caffeine or alcohol consumption, the use of screens before bedtime, or lack of physical activity can also disrupt sleep. Sleep apnea, restless legs syndrome and other sleep disorders are also detrimental to restful sleep. Last but not least, an uncomfortable mattress, noise or light can all contribute to a decline in sleep quality.

Consequences of sleep deprivation

Sleep deprivation has a negative impact on productivity and health.

It reduces concentration, decreases reaction time and increases the risk of errors and accidents. Sleep deprivation can also lead to cognitive impairment, a weakened immune system, and an increased risk of chronic diseases such as hypertension, diabetes and heart disease. Sleep deprivation also affects mood, increasing the risk of depression and anxiety.

Impact on physical health

Sleep deprivation promotes cardiovascular disease, diabetes and obesity. It weakens the immune system and increases the risk of hypertension and seasonal diseases.

Impact on mental health

Sleep deprivation also leads to more stress and anxiety, more depression and a reduction in cognitive ability. Sleep deprivation affects mood and motivation, and leads to a marked reduction in cognitive ability.

Impact on productivity

Sleep deprivation leads to reduced concentration and alertness, which in turn can lead to more frequent mistakes and accidents at work. Decision-making and problem-solving become difficult with a sleep deficit. Not getting enough sleep is also detrimental to creativity and innovation.

Limiting the impact of sleep deprivation

The ideal way to have a good day is to have had enough sleep, but this can sometimes be difficult, so we've put together some tips to help you make sure that lack of sleep doesn't affect your health or productivity.

Prioritize tasks

You can't be as efficient with a sleep debt as you can when you're in top form. To compensate for this and minimize the effects of sleep deprivation, task prioritization is effective because it enables you to focus on the most important and urgent tasks, and limit activities that require intense concentration or complex decisions that your state does not fully allow you to carry out in the best of situations.

Take regular breaks

We can't stress this enough, but taking regular breaks does wonders for productivity(The Power of Breaks). These breaks are all the more important when you're tired, so consider taking breaks every 90 minutes or so to improve your concentration and productivity.

Stay hydrated

Dehydration increases fatigue, so it's important to drink plenty of water. Make sure you drink between 1 and 1.5 liters of water a day, always carrying a glass or bottle of water with you(Santé pratique paris).

Incorporate relaxation techniques

Meditation, deep breathing and yoga can help you get off to a good start and limit the stress and anxiety caused by sleep deprivation.

Watch your diet

To stay in shape after a hard night's sleep, eat high-energy foods such as fruit, seeds and nuts, proteins and wholegrain cereals. Avoid fast sugars, as they cause energy crashes.

Take a nap

There's nothing like a little sleep to boost your energy. A 15-30 minute nap is perfect for increasing your alertness and performance without affecting your night-time sleep. However, avoid naps of 30 to 60 minutes, as you'll wake up during your deep sleep phase, which can lead to drowsiness when you wake up and affect the quality of your sleep this evening(Santé Magazine).

Get active

Moderate physical activity such as brisk walking or yoga can improve your energy levels and reduce stress, leading to greater productivity. What's more, exercise in the morning helps your body wake up for the day. However, be careful to avoid overly intense exercise at the end of the day, as it can disrupt your sleep. Sport can also be perfectly integrated into your workplace.

Limit your caffeine intake

Having a coffee in the morning can help you stay alert, but be careful not to overdo it, and consume it in small quantities. Avoid coffee in the afternoon, so as not to disturb your sleep the following night.

Expose yourself to natural light

Natural light helps to regulate your circadian rhythm and improve your state of wakefulness. In fact, it's daylight that sends the "day" or "night" information to your internal clock(Santé Magazine). Open your shutters when you wake up to expose yourself to daylight.

Design your working environment

Working in an ergonomic, well-lit workspace is easier. Using a comfortable chair and maintaining good posture will help you avoid additional physical pain and feel at ease. What's more, working in an ergonomic environment will protect you from RSI.

See our article on exercises and tips to prevent RSI.

These practices will help you maintain lasting productivity despite insufficient sleep.
