Physical and psychological effects of insomnia

Proper sleep is an important part of healthy lifestyle and sleep makes both psychological and physical health and helps to get ready for another day. Insomnia can have a serious effect on the body, which can affect work, energy level, focus, mood and performance. Sleep disorders don’t just cause sleeplessness. They can lead to other conditions and may have more serious and long-lasting effects on other organs, such as hypothyroidism, poor decision-making ability, poor coordination, hypertension, diabetes, and many other problems.

  • The central nervous system is something that can get affected by insomnia. A person with chronic insomnia may find it difficult to focus on work or learn new things. This can reduce coordination, affect mental abilities and the emotional state. It can also increase the risk for accidents.
  • It can also affect the immune system. During sleep, the body produces antibodies and cytokines to protect and fight infections such as bacteria and viruses. Various cytokines increase immunity to defend the body against illness and help to fall asleep. These get hampered due to lack of sleep.
  • The respiratory system can also take a hit due to sleep disorders. Obstructive sleep apnea is a night breathing disorder which can disturb sleep.
  • The digestive system is another body function that insomnia impacts. Less sleep affects the levels of two hormones, Ghrelin and Leptin, which control feelings of hunger and fullness. Leptin signals the brain that the body has enough food, and Ghrelin signals that the body needs more food. Sleep disorders can, therefore, lead to an increase in weight and obesity.
