6 Reasons For Excessive Daytime Sleepiness

Deep sleep is crucial for restoring the mind’s ability to learn and process things.

If the number of hours of a person’s night sleep is less than 7-8 hours, they aren’t sleeping enough to repair their body and mind.

The main way to prevent daytime sleepiness is to get adequate sleep at night to maintain a healthy life.

People with bad sleep schedules are more prone to problems like obesity, diabetes etc.

Here are some points to consider for your excessive daytime sleeping habits.

1. Sleep Deprivation

Not getting a good sleep like that, especially for several days in a week, is when a person will most likely begin to suffer from excessive daytime sleepiness.

The most evident and easiest solution is to get more sleep.

2. Poor Sleep Hygiene

Quality sleep is necessary for avoiding sleepiness during the day. Sleep hygiene refers to those habits which affect the quality of one’s sleep.

Poor sleep hygiene habits include:

  1. Having an irregular sleeping schedule

  2. Consuming caffeinated drinks late at night

  3. Usage sleeping pills

  4. Regular alcohol consumption

  5. Using mobile phones, laptops and other devices that emit blue light just before sleeping

  6. Taking long afternoon naps

  7. Eating just before hitting the bed

  8. Working out before bed

3. Hypothyroidism

The thyroid gland present behind the trachea, is responsible for producing hormones that regulate body metabolism and temperature.

Iodine deficiency or an autoimmune disorder may be the cause for hypothyroidism.

This is more common among women than in men.

Hypothyroidism can make you feel sluggish and sleepy all the time.

A person may tend to feel cold even when the others around you may feel warm. Lack of concentration, excessive weight gain and constipation are common symptoms of this condition.

Proper medication taken from a doctor can help cure this condition easily.

4. Narcolepsy

A person with narcolepsy, tends to abruptly fall asleep at unpredictable times. This could be even during an ongoing conversation.

Symptoms of narcolepsy are:

  1. Excessive daytime sleepiness

  2. Abruptly falling asleep

  3. Sleep paralysis

  4. Vivid dreams

  5. Loss of muscle tone

There is no standard cure for narcolepsy, though there exist few medications that can control abrupt sleepiness.

Daily physical activity and healthy eating and sleeping habits can help overcome this.

5. Periodic Limb Movement Disorder

Though most people are unaware, they might be involuntarily moving their arms and legs during their night sleep. The movement is sometimes significant enough to wake the person up.

People with this disorder complain of feeling unrested and of daytime sleepiness.

Though the cause of PLMD is unknown, studies say it may be related to anaemia or may be genetic.

6. Severe Anaemia

Severe anaemia is when the body may need blood transfusion to correct.

A person with severe anaemia is known to have constant headaches, feel exhausted and arrhythmic heartbeat which could adversely affect night sleep.

For all the young ones,  it may seem as if poor sleep is only impacting your days now and then due to work pressure, but lack of good sleep has its own long-term effects on mental and physical health which can cause serious harm to the body.

Getting a good sleep at night is very important to avoid daytime sleepiness.

A good 8-10-hour sleep makes the mind fresh and gives it the ability to function properly throughout the day.

If a person feels that even after good sleeping habits and good health, they are prone to feeling sleepy during the day, it is advised to visit a doctor and take necessary medications.
