Psychiatrists are medical doctors who have completed specialty training in psychiatry. They are able to prescribe medications, which is not something that psychologists can do. Psychologists have a doctoral degrees in psychology, and many of them specialize in psychotherapy - helping people work through their problems by talking about them. Psychiatrists are medical doctors who have completed a residency in psychiatry. They are able to prescribe medications. Psychologists are not medical doctors and do not prescribe medications. Psychologists typically have a doctoral degree in psychology.

The main difference between psychiatrists and psychologists is that psychiatrists are licensed to prescribe medication, while psychologists are not. Psychiatrists may also provide therapy, while psychologists generally do not. However, many psychiatrists also provide therapy, and many psychologists prescribe medication.

Psychologists, on the other hand, usually have a doctoral degree in psychology but are not licensed to prescribe medication. Psychologists are generally considered to be experts in the assessment of behavior and cognitive functioning, while psychiatrists are considered to be experts in both assessment and treatment. Psychiatrists are licensed to prescribe medication. Psychologists are not medical doctors, and they cannot prescribe medication. Psychologists often have a PhD or a PsyD degree in psychology.

Psychologists have a PhD or a PsyD in psychology. They do not prescribe medications, but they can provide therapy and assessment services. Some psychologists do have prescribing privileges, but this varies from state to state. Psychiatrists are medical doctors who specialize in the diagnosis and treatment of mental illness. Psychologists are not medical doctors, but they have graduate degrees in psychology and they can do psychological testing and therapy.

Psychiatrists can prescribe medications, while psychologists cannot. Some psychiatrists also do therapy, but many do not. Most psychologists do therapy. Psychiatrists can prescribe medications, which psychologists cannot. Psychologists typically have a doctoral degree in psychology but cannot prescribe medications. Psychologists provide therapy, which psychiatrists also do. So, psychiatrists are both therapists and prescribers of medication, while psychologists are therapists only.

Psychiatrists generally do a more detailed evaluation of a person's mental state and symptoms to make a diagnosis, while psychologists may only administer standardized tests. Psychiatrists usually provide long-term treatment for people with serious or chronic mental illness, while psychologists often provide short-term treatment or therapy. Psychiatrists have specialized training in the diagnosis and treatment of mental illness, whereas psychologists do not. psychiatrists can prescribe medication, whereas psychologists cannot.

How Cold Weather Affects Health: Understanding Winter’s Impact on the Body

How Cold Weather Affects Health: Understanding Winter’s Impact on the Body

Seasonal changes influence human health more than most people realise. Cold weather, in particular, places unique stress on the body and can worsen existing health conditions while increasing susceptibility to new illnesses. Understanding how cold weather affects health is essential for preventing seasonal complications and maintaining wellbeing during winter months.

In India, winter-related health issues vary by region but commonly include respiratory infections, cardiovascular strain and joint discomfort. According to the Indian Council of Medical Research (ICMR) and World Health Organization (WHO), cold exposure is associated with increased morbidity, especially among older adults and people with chronic conditions.

 

Why Cold Weather Impacts the Body

The human body works constantly to maintain core temperature. In cold environments:

  • blood vessels constrict to conserve heat
     

  • energy expenditure increases
     

  • immune responses may weaken
     

  • organs work harder to maintain balance
     

These adaptations, while protective, also create health vulnerabilities.

 

Increased Risk of Infections

Weakened Immune Response

Cold weather can suppress immune function, making it harder for the body to fight infections.

Factors contributing to winter infections include:

  • reduced vitamin D due to less sunlight
     

  • dry air affecting mucosal defenses
     

  • closer indoor contact
     

Common winter infections include colds, flu and respiratory illnesses.

 

Respiratory Health Problems

Cold air irritates the respiratory tract.

This can lead to:

  • worsening asthma symptoms
     

  • bronchitis flare-ups
     

  • increased cough and breathlessness
     

WHO reports higher hospital admissions for respiratory illnesses during colder months.

 

Impact on Heart Health

Cold temperatures affect cardiovascular function.

Blood Vessel Constriction

Cold causes blood vessels to narrow, increasing:

  • blood pressure
     

  • heart workload
     

This raises the risk of:

  • heart attacks
     

  • strokes
     

People with existing heart disease are particularly vulnerable.

 

Joint and Muscle Pain

Cold weather affects musculoskeletal health.

Common complaints include:

  • joint stiffness
     

  • muscle aches
     

  • worsening arthritis pain
     

Lower temperatures reduce joint lubrication and increase sensitivity to pain.

 

Metabolic and Weight Changes

Winter often leads to:

  • reduced physical activity
     

  • increased calorie intake
     

  • metabolic slowdown
     

These changes contribute to weight gain and worsen metabolic conditions such as diabetes.

 

Skin and Hydration Issues

Cold air holds less moisture.

This leads to:

  • dry skin
     

  • cracked lips
     

  • worsening eczema
     

Dehydration is also common as thirst perception reduces in cold weather.

 

Mental Health Effects

Seasonal changes can influence mental wellbeing.

Cold weather is associated with:

  • low mood
     

  • reduced motivation
     

  • seasonal affective symptoms
     

Limited sunlight affects circadian rhythm and serotonin levels.

 

Cold Weather and Older Adults

Elderly individuals face higher risks due to:

  • reduced temperature regulation
     

  • weaker immunity
     

  • existing chronic conditions
     

Winter-related complications are a significant cause of hospitalisation in older populations.

 

Why Chronic Diseases Worsen in Winter

Conditions such as:

  • hypertension
     

  • arthritis
     

  • asthma
     

  • diabetes
     

often worsen due to reduced activity, stress on organs and infection risk.

 

Preventive Strategies for Winter Health

Maintain Body Warmth

Layered clothing and warm environments reduce cold stress.

 

Support Immunity

Adequate nutrition, vitamin intake and sleep strengthen immune defences.

 

Stay Physically Active

Indoor exercises and regular movement prevent stiffness and metabolic decline.

 

Manage Chronic Conditions

Regular monitoring and medication adherence are critical during winter.

 

Hydration and Skin Care

Drinking fluids and using moisturisers prevent dehydration and skin damage.

 

Role of Preventive Healthcare

Preventive healthcare helps:

  • identify seasonal risk factors
     

  • adjust treatment plans
     

  • prevent winter complications
     

NITI Aayog highlights seasonal preparedness as an important public health strategy.

When to Seek Medical Help

Medical attention is necessary if:

  • infections persist or worsen
     

  • chest pain or breathlessness occurs
     

  • joint pain limits mobility
     

  • mental health symptoms interfere with daily life
     

Early care prevents serious outcomes.

 

Long-Term Impact of Ignoring Winter Health Risks

Ignoring cold weather effects may lead to:

  • severe infections
     

  • cardiovascular events
     

  • chronic pain progression
     

  • reduced quality of life
     

Seasonal awareness plays a critical role in long-term health.

 

Conclusion

Understanding how cold weather affects health allows individuals to take timely preventive measures. Winter increases the risk of infections, heart strain, respiratory problems, joint pain and mental health challenges. With proper warmth, nutrition, activity and preventive healthcare, most cold-related health issues are manageable and preventable. Seasonal care is not optional—it is essential for protecting health and wellbeing throughout the colder months.
