Patients suffering with sleep disorders are more likely to develop infections this winter.
This is the opinion of Dr Ellie Cannon, a GP who specialises in general health. She stated that getting enough rest each night is one of the most effective ways a person can boost their immune system, which would subsequently make them more resistant to diseases.
Other changes a person could make include adopting a healthier diet and participating in more exercise.
"Exercise boosts your circulation and your immune system. That is a great two-fold motivation to keep up the exercise," Dr Cannon added.
She also advised that proteins such as lean meats and fish can also help to improve a person's immune system.
The Royal College of Psychiatrists states that sleep disorders such as insomnia can be caused by emotional problems or depression and advises that people could seek cognitive therapy and stimulus control to help alleviate some of these issues.
