In diabetic patients, effective glycemic control is important in preventing complications, mortality and morbidity. The main purpose of DM treatment is to prevent neuropathic and vascular complications and to increase quality of life by keeping blood glucose levels and insulin activity within normal limits. It is stated that achieving the targeted glycemic control in diabetic patients reduces the risk of developing vascular complications in patients. In these patients, helping them reach the targeted glycemic level with lifestyle changes or medications is important in preventing the effects of diabetes on individual and community health. In effective DM monitoring and treatment, medical nutrition therapy (MNT), physical activity, drug therapy (OAD and insulin), DM education, patient self-monitoring and ensuring compliance with treatment are important. Although there have been significant developments in the field of treatment and follow-up today, there may be difficulties in achieving the targeted treatment goals in diabetic patients. This situation has led to the investigation of modifiable and non-modifiable factors affecting glycemic control in diabetic patients. Especially in Type 2 Diabetes, if these modifiable factors are diagnosed and managed early, effective management and control of diabetes can be achieved to a great extent. Especially psychological health and sleep health have become one of the new and mandatory modifiable risk factors for glycemic control in DM patients. Although it is known that diabetes is basically a disorder of the endocrine system, it has also been revealed that there is a relationship between psychosocial health and diabetes. Especially the presence of anxiety can cause an increase in blood glucose in diabetic patients, further worsening the patient's condition.Because emotional tension affects both neuroendocrine and hormonal pathways and indirectly the treatment and monitoring of diabetes, leading to blood sugar disorders. It is known that epinephrine secretion is stimulated by anxiety, which reduces the effect of insulin. Even in the simplest psychosocial stress and spiritual conflict, free fatty acids, cortisol and blood sugar increase. Therefore, stress and anxiety are considered important factors in patients whose blood sugar cannot be regulated despite medical treatment. In such cases, psychosocial evaluation should be made before increasing the insulin dose. In addition, studies in the literature show that in addition to the effect of anxiety on glycemic control, poor glycemic control also has an effect on the emergence of anxiety and a positive mutual relationship has been found between anxiety and glycemic control. Therefore, it was emphasized that anxiety and depression levels should be determined in order to consider diabetic patients as a whole. Sleep is a biological requirement and a physiologically active process. It repairs the body by giving strength to the mind and memory. Sleep quality is defined as the efficiency of sleep. Within the scope of sleep quality; sleep efficiency, number of sleep interruptions, total sleep duration, wakefulness duration, sleep transition time and spontaneous awakenings. Sleep, in addition to productivity and efficiency, positively affects cognitive functions such as memory and concentration, and contributes to physical and psychological renewal. Due to such positive effects, sleep is seen as an important variable affecting the individual's quality of life and well-being. Therefore, disruptions that may occur in sleep quality and sleep patterns cause problems such as inability to concentrate, anxiety, depression, increased sensitivity to pain, irritability, hallucinations, loss of appetite and difficulty in excretion, and directly affect the individual's daily life and general health. Therefore, it is important to take sleep health into consideration in order to ensure glycemic control in DM patients.

PURPOSE: This study will be conducted to examine the Effect of Sleep Hygiene Education and Progressive Relaxation Exercise on Sleep Quality, Anxiety and Glycemic Control in Type 2 Diabetic Patients.

Today, it is known that sleep disorders are quite common in DM patients. In addition, it has been demonstrated that there is a two-way relationship between DM and sleep. The American Diabetes Association (ADA) included sleep as a behavior to be monitored among adults living with DM in its 2022 care standards .The American Academy of Sleep Medicine has also reported a relationship between sleep deprivation and sleep disorders and the progression or seriousness of DM, and stated that DM alone has an effect on sleep quality. Studies in the literature have also shown that sleep quality problems negatively affect diabetes, and a positive relationship has been found between poor sleep quality and hemoglobin A1c (HbA1c). The reason for this is; physiopathologically, in the NREM deep phase of sleep, sympathetic nerve activity decreases and the level of anti-insulin growth hormone increases, and in the second half of sleep, especially in the REM phase of sleep, the level of plasma cortisol, one of the anti-insulin regulatory hormones, increases.

In individuals with poor sleep quality and sleep disorders, the physiological state begins to deteriorate and glucose utilization decreases as a result of increased sympathetic activity, decreased growth hormone, and increased catecholamine and cortisol levels, and hyperglycemia and insulin resistance develop due to glycogenolysis and gluconeogenesis.Another reason is that short and poor sleep duration alters the ability of leptin, which has appetite suppressant properties, and ghrelin, which has appetite stimulant properties, to accurately report the body's calorie needs. This can lead to excessive calorie intake and obesity.Changes in the release of all these hormones that provide energy balance can lead to the risk of developing diabetes and deterioration in glycemic control and micro and macrovascular complications in people with diabetes. In the literature has been shown that insufficient sleep duration and decrease in sleep quality is associated with impaired glucose tolerance and insulin resistance. IAmong the reasons for this effect of sleep in these studies, it is stated that when sleep duration is insufficient and its quality is low, the risk of developing obesity, hyperglycemia and insulin resistance increases due to changes in the secretion of hormones that affect energy intake and expenditure. Therefore, it is important to consider sleep health in order to ensure glycemic control in DM patients. Nurses, who are in constant communication with patients, have important roles in determining the factors affecting the sleep quality of individuals and their sleep needs, diagnosing sleep disorders, and providing treatment. It is seen that the item "Sleep and rest", which is one of the physiological needs, is included in the nursing theory developed by Henderson, one of the important theorists. It is seen that the diagnosis of sleep pattern disturbance is also among the nursing diagnoses determined by NANDA. Therefore, sleep has an important role in nursing care. In addition, there are nursing interventions to improve sleep quality in DM patients. These interventions include sleep hygiene education, cognitive behavioral therapy, health education, music therapy, massage, aromatherapy. Among these interventions, in sleep hygiene education; not going to bed without feeling sleepy, not spending too much time in bed other than sleeping, not forcing yourself to fall asleep, setting sleep routines before going to bed, not taking daytime naps or sleeping, if taking daytime naps, not consuming carbonated drinks or caffeinated products at least 3-4 hours before going to bed, not going to bed hungry, avoiding heavy meals, stressful activities and strenuous movements before going to bed. Some studies were found that sleep hygiene training increased the quality of sleep in Type 2 DM patients. Relaxation exercises, which are effective in activating the parasympathetic system in DM patients, can also be used along with approaches such as sleep hygiene. Progressive relaxation exercise (PRE), one of these exercises, is a method that provides relaxation throughout the body by regularly and voluntarily relaxing large muscle groups in the human body. PRE is an intervention that nurses can teach. Relaxation exercises, one of the effective methods on anxiety and sleep; It is a widely used, effective and inexpensive method to change the behavior and mental processes of the individual. Recently, PGE has also started to be used in diabetes management. In an study conducted on diabetic patients, examining the effect of PGE on blood sugar, it was observed that there was a significant difference in the blood sugar levels of the experimental and control groups. The reason for this situation is thought to be due to the minimization of stress by controlling negative emotions with PGE . In another study examined the relationship between PGE and HbA1c in their randomized controlled study with Type 2 DM patients. According to the results of the study, positive improvements were observed in the HbA1c level of the experimental group, while there was no difference in the control group. It is thought that the reason for this situation is that hormonal activities become stable as PGE reduces stress Although the effects of PGE on sleep quality and glycemic control have been addressed separately in the literature, there is no study showing the effects on sleep quality and glycemic control at the same time. Therefore, it is thought that this study will emphasize the importance of using non-pharmacological interventions in the management of decreased sleep quality and anxiety affecting glycemic control in diabetic patients and will raise awareness about health professionals who apply these non-pharmacological interventions. In addition, it is thought that it will contribute to the literature because it is an evidence-based initiative in the field of nursing.
