20 Signs of TOO MUCH Stress – Dr. Berg
For example, a recent study of more than 7,000 working adults found that fatigue was “significantly associated” with work-related stress (3Trusted Source).
Stress may also disrupt sleep and cause insomnia, which can lead to low energy.
A 2018 review published in the Journal of Sleep Research found that “stress-related worry and rumination” can lead to disrupted sleep and eventually the risk of developing insomnia (4Trusted Source).
Another study of 2,316 participants showed that exposure to stress was associated with an increased risk of insomnia (5Trusted Source).
Both of these studies focus in on sleep reactivity, or the extent to which stress affects the ability to fall sleep or remain asleep.
