Lack of sleep increases the risk of obesity and depression

Lack of sleep increases the risk of obesity and depression

We all know that sleep plays a vital role in good health and well-being throughout our lives. However, it might be even more important than you realized.

Persistent lack of sleep can lead to depression within 1 year.

Research shows that ‘of the many potential difficulties likely to be associated with depression, the single most common symptom, affecting more than 65% of outpatients and 90% of inpatients diagnosed with major depression, is some type of SLEEP DISTURBANCE’ (McCall, Reboussin & Cohen, 2000).

‘Insomnia is the most common sleep disorder related to depression’ (Roth & Roehrs, 2003).

‘In a prospective study of non-depressed subjects from the general population, complaints of persistent sleep disturbances were risk factors for the onset of depression within one year’ (Thase, 2000), because sleep affects your physical, mental and psychological health. Sleep helps you pay attention, make decisions, feel energetic, alert, have positive emotions and function properly.

If you’re sleep deficient, you will have trouble making decisions, solving problems, learning, remembering, controlling your emotions and behaviour, and coping with change. People who are sleep deficient may have problems getting along with others. They may feel cranky and impulsive, have mood swings, feel low and lack motivation.

Sleep deficiency increase the risk of obesity.

A growing body of research suggests that there’s a link between how much people sleep and how much they weigh. In general, children and adults who get too little sleep tend to weigh more than those who get enough sleep.

For example, in the Nurses’ Health Study, researchers followed roughly 60,000 women for 16 years, asking them about their weight, sleep habits, diet, and other aspects of their lifestyle.  At the start of the study, all of the women were healthy, and none were obese; 16 years later, women who slept 5 hours or less per night had a 15 percent higher risk of becoming obese, compared to women who slept 7 hours per night. Short sleepers also had 30 percent higher risk of gaining 30 pounds over the course of the study, compared to women who got 7 hours of sleep per night.

There are several reasons for why sleep deprivation could increase the chances of becoming obese:

  1. Sleep-deprived people may be too tired to exercise, decreasing the “calories burned” side of the weight-change equation.
  2. People who don’t get enough sleep may take in more calories than those who do, simply because sleep deficiency makes them lack energy, so they wrongly try to fix that by getting energy from extra food.
  3. Lack of sleep also disrupts the balance of key hormones that control appetite and send us ‘a fullness signal’. If we don’t get enough sleep, then we are more likely to overeat, as we won’t get ‘a fullness signal’ once we had enough to eat.

 

Sleep is also involved in healing and repair of your heart and blood vessels. Ongoing sleep deficiency is linked to an increased risk of heart disease, kidney disease, high blood pressure, diabetes, and stroke

To conclude, make getting enough sleep your priority at night. Adults need on average 7-8 hrs of sleep at night, teenagers: 9hrs.

If you suffer from insomnia (difficulty in initiating and or maintaining sleep), then it is recommended that you to seek help.
