How to deal with afternoon fatigue

Experts say that circulated rhythms decide how the body functions flow and flow through about a long -term cycle, and these rhythms are largely determined by the biological “clock” in the brain. Meanwhile, sleep pressure is the idea that our need to sleep gradually builds, the longer we wake up.

Our circadian rhythms are affected by the environment, which means that we usually feel awake and vigilant during daylight and more sleeping airy when it is shadowy. But some fluctuations are normal: for example, people feel quite sleepy overdue in the morning, said Dr. Alon Avidan, professor of neurology at the University of California in Los Angeles, but in the afternoon they experience immersion in vigilance – when – when – when – when – when some neurotransmitters related With a sense of awakening, they may become less energetic.

Sleep pressure is generally the lowest when we wake up in the morning – the body is like “a battery that is fully charged with good sleep,” said Dr. Avidan. But the longer we wake up, the more our energy leaves and the stronger sleep pressure, he added.

During the afternoon decline, these two forces – sleep pressure and circulated rhythms – basically “fight with each other,” said Dr. Ravi Allada, executive director of the Michigan Institute at the University of Michigan. When we feel drowsy, the pressure to sleep wins the fight, he said.

As long as this feeling lasts, it may be different, but people tend to “second wind” early in the evening, said Dr. Avidan. The discount, however, may get worse if you are without sleep or have an irregular sleep schedule, said David Earnest, Professor of Neuronuki and experimental therapeutic at the Texas A & m University. He said that sleep disorders, including insomnia or sleepless apnea, could also exacerbate this feeling.
