The CDC estimates that nearly 35% of American adults do not get six hours of sleep a night. Many even work all night and miss out on nightly sleep entirely, leading to a buildup of sleep deprivation that affects the body in myriad ways, including negatively affecting the immune system, appearance, and brain function.

Puffy eyes and dark circles, cravings and hunger that can contribute to obesity, lack of concentration at work or homework, frequent infections due to lack of immunity are some of the reasons why our body is affected by insufficient sleep.

Our bodies induce sleep by increasing circulating levels of the neurotransmitter adenosine and using signals from our circadian clock, which controls our circadian rhythm. These two systems work together to determine the best time for us to go to bed. Most of us reach peak levels of “tiredness” between 12:00 pm and 6:00 am and between 2:00 pm and 4:00 pm.

Lack of sleep affects the body and mind. Our circadian clock regulates our bodily functions, including fluctuations in blood pressure, body temperature, and levels of various hormones and digestive enzymes. In a University of Chicago study of human sleep deprivation, volunteers who slept only about 4 hours a night for 6 consecutive days experienced increased blood pressure, increased stress hormones, cortisol levels, and decreased levels of antibodies against the flu vaccine. They also showed signs of insulin resistance, a precursor to type 2 diabetes.

Sleep deprivation also causes irritability and fatigue, as well as impairs memory and concentration, impairing reaction time, judgment and vision. The greater the sleep debt, the greater the health impacts such as weight gain, heart disease, diabetes and even stroke.

Repairs the effects of sleep deprivation

Adults who don't get the recommended hours of sleep during the workweek should focus on making up for it on the weekend. Adequate sleep is as important to a healthy life as diet and exercise. Paying off your sleep debt can be a challenge for those with busy schedules, but adding a few extra hours of sleep every night for the next week goes a long way.

It can take a few weeks or even months to fully recover from the negative effects of sleep deprivation, but it's important to sleep with your alarm off a few days a week and wake up feeling refreshed and relaxed. Equally important is avoiding falling back into a new cycle of debt. Factor your sleep needs into your schedule and plan your days and nights accordingly.

Important points to remember

naps during the day

  • Choose the right time– Taking a nap at the wrong time of day can disrupt your normal sleep pattern. The best time to nap during the day is after lunch when your body's energy levels start to drop.
  • Keep it short -Make sure you only take short 20-30 minute naps during the day. Naps that last an hour or more can disrupt nighttime sleep.
  • Choose the right place -Plan your nap well by choosing a comfortable room with low light and minimal noise.

night of sleep

  • Limit your caffeine intake –Consuming too much caffeine after noon can keep you awake at night and interfere with deep sleep at night.
  • be active -Exercise regularly to go to bed tired.
  • reduce irritation- Allow your brain to shut down by turning off cell phones and computers well in advance (at least an hour before bed). If you need to use phones, turn on the backlight or night light on smartphones to be easy on the eyes. Reading a printed book in bed can be a great way to relax and calm your brain.

    The author discusses the effects of voluntary minor sleep deprivation. The cumulative effect of losing a few hours of sleep and the damage of not sleeping well are desirable. But not once is the question of the title discussed. What are the effects of a person sleeping during the day instead of at night? Nowhere in this question is it assumed that the sleeper is not getting enough sleep, only that sleep comes at an unusual time.

    This article should not be provided as a search result for anyone looking for information on daytime and nighttime sleep schedules. It has a misleading title and does not contain any relevant information about the subject that most readers want to study.
