Many people have late sleep and late waking up habits including persons who are forced to work late evening. Are there any health consequences? According to health experts, late sleep can be harmful for your physical and mental health by triggering overweight, additional stress, diseases and disturbing daily routine. Here are some late sleep negative effects:
Delayed sleep syndrome
If you go to sleep late every day, it would become your fixed habit and after some time you would not be able to sleep earlier. This phenomenon called “Delayed sleep syndrome” when the sleep biological cycle begins late.
Headaches and back aches are common complains of late sleepers. It was noted that sleeping late can affect brain functions and trigger frequent headaches. Health experts couldn’t explain the origin of back aches in late sleepers.
In most cases late sleep means late weak up time which could lead to reduced concentration and mood changes. It is not natural to function beyond natural body clocks. You are taking risk to be behind of others.
Dark under eye circles
Dark circles under the eyes of women are the most unpleasant late sleep side effect. According to health experts, the main reason behind the appearance of dark under eye circles is inadequate sleep or change of sleeping hours.
Obesity and not healthy eating habits
Late sleep means longer time for food consumption which could result weight gain.
“People who go to bed late and sleep late eat more calories in the evening, more fast food, fewer fruits and vegetables and weigh more than people who go to sleep earlier and wake up earlier,” according to a study from Northwestern University Feinberg School of Medicine.
It was noted that late sleepers have not healthy habits to drink diet soda, sugary drinks and energy drinks at night time. In addition, late sleepers often skip their breakfast and tend to consume fast food. Most late sleepers suffer from short sleep which can cause weight gain. If you go to bed late and weak up late, you have no chances for healthy early morning physical exercises.
Reduced sleep duration
If you went to sleep late and should go to work in the morning, it means you did not have enough sleep (at least 7-8 hours). Sleep duration and sleep quality are crucial for our health. Sleep deprivation could cause anxiety, weakened immune system, increased cardiovascular risks, obesity and increased risks for breast cancer.
Weakened immune system
In most cases late sleep correlate with lack of sleep which have been linked to weakened immune system. Staying up late at night destroys your white blood cells that give your body immunity. It was noted that many college students who study at night and specialists with night shifts get sick more frequently. Weakened immune system means reduced ability to control and eradicate several diseases including early stages of cancer.
Reduced melatonin production
Late sleep and reduced duration of sleep lead to decreased levels of melatonin which can be produced only during night (dark time) sleep. Melatonin supports hormone regulations and maintains body’s circadian rhythm. Actually the melatonin is responsible for body clock. Reduced melatonin production could trigger several diseases including cancer development.
Negative emotion or depression
Often stress depends on daily sleep duration. Late sleepers find themselves more stressed. According to health experts, not healthy sleeping habits (including late sleep) could cause mental disorders including anxiety, depression, Schizophrenia and Alzheimer’s disease.
Late sleepers are at risk of insomnia, sleep apnea or narcolepsy.
It was noted that sleeping late has an adverse affect over the voice quality and tone. The voice grain becomes too hoarse and rough, as you get into the habit of waking up late.
Late sleep triggered diseases
Late sleepers have increased levels of hormone cortisol which is responsible for increased blood pressure and reduction in cell regeneration activity. It means late sleepers are at risk of diabetes, hypertension, heart diseases and cancer.
