For those woken up at night by the slightest sound, lack of quality sleep may not be the only problem, experts report.

Sleeping too lightly can put you at risk for many diseases, according to the Sleep Foundation.

Endocrinologist Dr. Anis Rahman has confirmed that poor sleep is linked to type 2 diabetes, high blood pressure and cardiovascular disease.

type 2 diabetes

The National Health Service (NHS) states that the most common signs of type 2 diabetes are:

Urinating more often than usual, especially at night

Feeling thirsty all the time

I feel very tired

Slimming without effort

Frequent thrush

Wounds take longer to heal

blurred vision

And you can have your blood sugar checked by a doctor with a blood test and the results will show if you have diabetes or not.

high blood pressure

The British Heart Foundation (BHF) warns that high blood pressure can be a life-threatening condition because it increases the risk of heart attacks and strokes.

Although high blood pressure may not show any symptoms, in some cases it can be accompanied by signs such as:

blurred vision


– shortness of breath

– chest pain

– Dizziness


The best way to find out if you have high blood pressure is to have it checked at your doctor’s office or pharmacy, or buy a blood pressure monitor.

Cardiovascular diseases

Symptoms of cardiovascular disease may include:

– chest pain

Pain, weakness, or numbness in the legs or arms

– hard breath

Very fast or slow heartbeat or palpitations

Feeling dizzy, dizzy, or fainting

– fatigue

Swelling of the extremities

Light sleepers fall awake in response to small disturbances, such as moving a partner into sleeping position, noise outside, or turning on a light in a hallway.

Dr. Rahman stressed that light sleepers are also at risk of developing obesity and certain types of cancer.

Although researchers couldn’t fully understand why a person sleeps lightly compared to those who sleep deeply, their arousal threshold is much lower. The arousal threshold describes how strong the stimulus is to wake you up.

How to sleep better if you sleep lightly?

Light sleepers can help themselves by participating in good, healthy sleep.

When possible, healthy sleep habits include getting up and going to bed at the same time each day and night.

Creating a calming bedtime routine that includes the same steps in the same order can prepare the brain for bedtime.

It is recommended that you avoid electronics and blue light for 60 minutes before trying to sleep.

And if you tend to sleep during the day, stop doing so, as sleeping more than 30 minutes can make it difficult to sleep at night.

Blackout curtains can help reduce the amount of light entering the bedroom that can wake you up.

And if you’re still having trouble sleeping at night, it might be worth making an appointment with your doctor.
