Electromagnetic Radiations

Introduction and Aim: Sensitivity to electromagnetic radiation is the emerging health problem of the 21st century. The sensitivity to electromagnetic radiations has become the major issue to be highlighted as environmental intolerance to Wi-Fi. These Wi-Fi radiations are a form of stress and thereby tend to increase salivary cortisol levels. Hence this study was done to analyse the effect of Wi-Fi radiations on salivary cortisol levels. The aim of the present study is to study the effect of Wi-Fi radiation from mobile phone towers on salivary cortisol levels. Materials and Methods: This study incorporated analysis of salivary cortisol levels in 72 healthy volunteers who were divided into two groups, subjects residing within 100 mts of the location of mobile phone towers and subjects who were residing outside 100 mts of the location of mobile phone towers and both groups were age & sex matched. The data was statistically analysed using the ANOVA with the SPSS software15.0 version. Results: The study showed that the salivary cortisol level increased in those subjects staying within 100 meters of the location of mobile phone towers compared to the subjects residing outside 100 mts of the location     of mobile phone towers. Conclusion: From this study, it is concluded that Wi-Fi radiation causes invisible damaging effects by increasing the levels of salivary cortisol and vigorous measures to be taken to safeguard ourselves from these radiations.

The Impact

Aromatherapy is one of the complementary therapies to improve health. The aromatic essential oils have been used in the treatment procedure through inhalation of essential oil vapor, massage, and herbal bathing. Litsea species are generally used in traditional medicine, and Litsea cubeba (Lour.) Persoon is a potent fumigant plant, used in cosmetics and foods as essence. The chemical composition of the essential oil of different parts of L. cubeba has been found to be varied. L. cubeba essential oil (LEO) is known for the treatment of cognition-associated discomforts. The current study assessed the impact of inhalation of LEO on mood states and salivary cortisol levels of healthy people. Fifteen healthy volunteers were involved in the study. The Profile of Mood States (POMS) Questionnaire and ELISA methods were employed to determine the mood states and salivary cortisol level, respectively. (-)-β-pinene, β-citral, cis- and trans-citral, citronellal, limonene, linalool, and 6-methyl-5-hepten-2-one were detected in LEO by GC-MS analysis. The heart rate and blood pressure were not affected significantly during LEO exposure. The inhalation of LEO significantly improved the total mood disturbance and reduced the confusion among the healthy human subjects. LEO inhalation reduced the salivary cortisol level at a notable level. The results of the current study warrant further studies on the beneficial effect of LEO aromatherapy in healthy and diseased subjects to uncover the therapeutic nature of the L. cubeba plant.

Current data report that high levels of dental anxiety in children have a negative impact on oral health. The aim of this study was to measure dental anxiety, based on the Abeer Children Dental Anxiety Scale (ACDAS) used as a self-reported measure and to correlate its values with the salivary cortisol levels. The study was conducted in 2019 and included 389 children aged 6–9 years old; evaluation of dental anxiety and saliva sampling were performed. The influence of gender on the presence of dental anxiety was analyzed using Fisher’s exact test, the salivary cortisol level was compared between anxious and non-anxious children and was further correlated with the ACDAS score (p < 0.05). Girls had higher odds of experiencing dental anxiety (odds ratio: 1.533, p = 0.041). Salivary cortisol levels were higher in anxious compared to non-anxious children (median 1.251 vs. 1.091 ng/mL, p < 0.001) and showed a positive moderate correlation with the ACDAS score (r = 0.411, p < 0.001). Children aged 6–9 years have a high prevalence of dental anxiety, with girls being more susceptible to this condition. Salivary cortisol levels are higher in anxious children and correlate positively with the ACDAS score, proving that ACDAS can be used for the detection of dental anxiety.

Abstract The objective was to study the peculiarities of hormonal stress in preterm infants in the NICU and their mothers, and to investigate how skin-to-skin contact influences it. The study included 60 preterm infants with GA˂32 weeks who were treated in NICU and their mothers. The overall design was a baseline-response design. Saliva was collected before (baseline) and after skin-to-skin contact to measure cortisol by enzyme immunoassay method. Infant baseline salivary cortisol level was 0.587 [0.239; 1,714] µg/dL. It was significantly higher in neonates who had invasive ventilation (1.00 [0.38; 2.44]) µg/dL compared to non-ventilated infants (0.335 [0.156; 1.236]) µg/dL, p = 0.022; and positively correlated with the Apgar score at 1st and 5th minutes (r=-0.36; p = 0.011 and r=-0.34; p = 0.017) and duration of ventilation (r = 0.70; p = 0.0000). Maternal baseline salivary cortisol level was 0.212 [0.123; 0.378]µg/dL. There was significant decreasing of salivary cortisol after Kangaroo mother care with skin-to-skin contact in infants (0.162 [0.111; 0.231]) µg/dL, p˂0.001 and mothers (0.096 [0.077; 0.156]) µg/dL, p˂0.001. Conclusion: Preterm infants in the NICU and their mothers experience stress confirmed by the increased baseline cortisol levels. Kangaroo mother care with skin-to-skin contact reduces the stress and normalizes salivary cortisol levels in both infant and mother in the NICU.

BACKGROUND: Hypothalamic-pituitary-adrenal axis and its end product cortisol have been extensively investigated in patients with depressive disorders for many years. Recently, salivary alpha-amylase (sAA) had emerged as a new biomarker with non-invasive and more convenience protocol for measuring sympathetic activity which were also associated with depression. Selective Serotonin Reuptake Inhibitor is antidepressant drug extensively used to treat depression. AIM: The aim of this study was to determine whether decrease of sAA and salivary cortisol levels could be observed in subjects with depression who were treated by fluoxetine. METHODS: The total subjects were 25 depressed subjects and ten healthy controls. sAA was examined before therapy, and after 2, 4, and 6 weeks of fluoxetine administration using a portable cocorometer. Salivary cortisol was examined before therapy, after 4 and 6 weeks of fluoxetine administration with Elisa method. The therapeutic effect was assessed with Hamilton Depression Rating Scale (HDRS). RESULTS: sAA and cortisol levels were significantly decreased after fluoxetine administration (p < 0.001), followed by at least 50% reduction of HDRS scores after 6 weeks of fluoxetine administration. Levels of sAA and cortisol were higher in the depression group than in the healthy control. CONCLUSIONS: Measurement of sAA levels can be used as a potential biomarker of therapeutic response in depressed patients in addition to salivary cortisol.

Patients with cancer will experience limitations in meeting their daily needs, including psychological problems such as stress. Stress can be assessed through cortisol saliva as a biomarker of stress. Foot Reflexology will help restore the body's energy balance, stimulate relaxation and endorphins, and reduce stress. To determine the effect of foot reflexology to reduce salivary cortisol levels as a biomarker of anxiety for patients with cancer. Adult patients with cancer in stage II and III hospitalized in a Public hospital in Central Java, Indonesia, were invited. Foot reflexology was given once (40 minutes) a day. Saliva collection was carried out two times a day (30 minutes before intervention) and 15 minutes after intervention. Salivary cortisol levels at baseline and post-intervention were measured and compared to determine the effect of foot reflexology. Data were analyzed using the Wilcox on signed-rank and effect size (ES) test. Fifty-five patients (93.2%) participated in this study. We found that the effect size of foot reflexology was 0.82 (ρ = 0.001) with a mean and standard deviation of salivary cortisol levels at baseline and post-intervention were (9.31 ± 5.45 and 6.17 ± 4.55) respectively. These findings indicated the significant effect of giving Foot Reflexology Massage in reducing salivary cortisol levels. Foot Reflexology massage is proven to have a substantial impact on reducing the Salivary cortisol level as a stress biomarker.

The present study investigates the usage of social media networking behavior among the MAHSA university students by using structured questionnaire. The salivary cortisol levels among the study groups were estimated. In addition, the association between salivary cortisol and the usage of social media networking was also assessed. Saliva samples were obtained twice a day from selected subjects to analyze the cortisol level. Results of the present study indicate that the 11% of the students spend less than one hour on social media, 40.2% uses two to four hours and 46.4% more than four hours daily; whereas, 2% of the study groups are others. The cortisol levels assessed among the male and female study groups showed high cortisol concentration in both morning and evening. The cortisol levels in the morning seen among the male study group ranges from 0.13-5.49 µg/dl and the female cortisol level ranges from 1.11-5.72 µg/dl. Besides in the evening, the cortisol levels seem to be higher among the study group. The evening cortisol level of male students ranges from 0.06-4.6 µg/dl. Whereas in the females, cortisol level ranges 0.263.9 µg/dl. The average value of the cortisol concentration in the morning is seen to be higher among the female study group than the male and in the evening the male cortisol concentration is seen to be higher than the females. Results clearly demonstrated that students spending more hours in social media had higher cortisol levels when compared to less hour users. From the present preliminary study, it is clear that there is an association between salivary cortisol level and the usage of social media networking behavior.

Background. Rooming-in practice improves breastfeeding and reduces newborn stress reactivity. When this modality is not available, partial rooming-in after birth can be considered. Salivary cortisol levels (SCLs) are considered reliable biomarkers to indicate stress. Objective. To test the hypothesis that rooming-in duration impacts neonatal stress response in hospitalized newborns. Design/methods. Forty term newborns, enrolled in the Neonatology and Obstetrics Nursing, C.G. Ruesch, Naples, Italy, were divided, according to the mother’s choice, into the study (SG; n=20) and control (CG; n=20) groups if they received full (24 hs) or partial (14 hs) rooming-in care, respectively. Saliva samples were collected from all babies between 7:00 a.m. and 8:00 a.m. of the 3rd day of life by using oral swab. Salivary cortisol levels were measured using an enzyme immunoassay kit (Salimetrics LLC, PA, USA). Results. A statistically significant difference in the SCLs between SG and CG was found (median: 258 ng/dl versus 488.5 ng/dl; p=0.048). Conclusions. Data support the practice of full rooming-in care compared with partial rooming-in. The rooming-in duration clearly reduces SCLs and likely neonatal stress. These lower SCLs may have long-term positive effects reducing the risk of metabolic syndrome, high blood pressure, and cognitive and behavioural changes.
