Lack of sleep intensifies anger, impairs adaptation to frustrating circumstances
Losing just a couple hours of sleep at night makes you angrier, especially in frustrating situations, according to new Iowa State University research. While the results may seem intuitive, the study is one of the first to provide evidence that sleep loss causes anger.
Other studies have shown a link between sleep and anger, but questions remained about whether sleep loss was to blame or if anger was responsible for disrupted sleep, said Zlatan Krizan, professor of psychology at Iowa State. The research, published in the Journal of Experimental Psychology: General, answers those questions and provides new insight on our ability to adjust to irritating conditions when tired.
“Despite typical tendencies to get somewhat used to irritating conditions — an uncomfortable shirt or a barking dog — sleep-restricted individuals actually showed a trend toward increased anger and distress, essentially reversing their ability to adapt to frustrating conditions over time. No one has shown this before,” Krizan said.
Eight things you can do to improve sleep:
Avoid alcohol, large meals, exercise and smoking at least two to three hours before bed.
Turn off from work and technology at least an hour before bed.
Go to bed as soon as you feel tired. If you wait too long, it will be harder to fall asleep.
Avoid watching TV or reading an exciting page-turner in bed.
Go to bed at around the same time each night. Ideally this should be before midnight.
Sleep in a dark, well ventilated room.
Deep sleep is the phase of sleep where you benefit most. It happens in the first third of your sleep. Avoid environments where you could be disturbed during this phase.
Aim for seven to nine hours of sleep per night

How sleep issues can affect anger expression in couples and negatively affect relationships and communication?
Sleep is probably the most underrated of habits that impact health and wellbeing. A lack of sleep the night before is enough to leave us tired, grumpy and fed up for the rest of the day. Getting the right amount of rest is crucial to tackling everything the world has to throw at us and that includes how we interact & communicate with other people especially with our spouses. But why? Let’s examine in closer detail exactly what it is about sleep that has such an impact on us.
Why is sleep important in a relationship?
The short answer to this question is that it affects our “Emotions”. The body needs time to recover at the end of every day. Not getting enough sleep has the potential to hinder our social abilities. It becomes harder to recognize communication cues when tired, and affects how we react to the behavior of others.
What happens to the body with lack of sleep?
What will actually happen if we don’t get enough sleep? Some of the potential dangers associated with getting less sleep include:
Weight gain – Sleep plays an important role in burning calories. As such, not getting enough can cause someone to pack on the pounds. It’s also been claimed that sleep-deprived people have lower levels of leptin. This chemical is what controls our ability to feel full. As such, you’re prone to eating more as a direct result of a lack of sleep.As well as these more specific side effects, you’ll also experience exhaustion throughout the day. Constantly feeling like you need to sleep is no way to get through the day productively. In some extreme circumstances, it may even result in death. Such was the case with SAP CEO Ranjan Das.
Lowered concentration levels – Your ability to focus will be drastically impacted if you’ve missed too much sleep.
A lowered sex drive – Your sex life might suffer if you’re not getting enough sleep. The NHS recently published information highlighting how a lack of sleep affected both males and female libidos. This could have a detrimental impact on your relationship.
Dangers associated with a lack of sleep
As you may have already realized, there are a number of dangers, which go hand-in-hand with not getting enough rest. These include:
Mood disorders – Studies have suggested mental illnesses can be caused, or heightened, as a direct result of not getting enough sleep. This occurs as a result of neurotransmitters in the brain being damaged, causing the brain to experience the same symptoms associated with depression and anxiety.
Raised blood pressure – Owing to the aforementioned close association of the heart and sleep, it should come as no shock blood pressure is affected when a person misses out on sleep. Increased pressure is the natural side effect of additional strain being put on the cardiovascular system.
How much of an impact a lack of sleep can have on your daily performance?
Physical exercise – Physical activity will also be impaired by a loss of sleep. There are a number of ways in which your body will be negatively affected if you over-exert yourself.
Psychological Effect – It’s a vicious cycle when it comes to sleep and exercise. You’re bound to feel less motivated if you don’t get enough sleep. Naturally, this will have a negative impact on your abilities to push yourself on the workout itself. You may not feel like you want to do any activity at all.
You’re going to notice a significant difference in your motivation, recovery and performance levels when you miss out on sleep. If you have an important day of activities ahead, make sure you always get the right amount of rest the evening before.
In short, not getting enough sleep puts us at an instant disadvantage in almost every aspect of daily life from both a health and social perspective.
